Zoonosis is the spread of diseases from animals to humans. Rabies is a clinical example of a zoonotic infection.
What is Zoonosis?
Zoonosis, also known as zoonotic disease, is an infection or disease that can spread from animals to humans. This transmission can occur through various mechanisms such as direct contact with infected animals, consumption of animal products like meat or milk, or through vectors such as mosquitoes and ticks, which transfer disease-causing pathogens to humans from infected animals.
In fact, about 60% of infectious diseases that affect humans are of animal origin. Some of the most well-known examples of zoonotic infections include rabies, Ebola, West Nile virus, salmonella, and anthrax.
Clinical example of a zoonotic infection:
Rabies is a clinical example of a zoonotic infection. Rabies is a viral disease that can infect any mammal. The virus attacks the nervous system and spreads through the saliva of infected animals via bites or scratches.
Rabies can infect humans when they come into contact with the saliva of an infected animal. This can happen if an infected animal bites or scratches a person, or if an infected animal's saliva comes into contact with an open wound, cut, or scratch on a person's skin.

Why do you believe that quality can be viewed as a strength and
a weakness of the U.S. health care system? Post atleast 300
words
Put 2 examples and explanation and reference
The quality of the U.S. health care system can be viewed as both a strength and a weakness.
The United States has one of the most advanced health care systems globally, but this quality comes with significant drawbacks. Despite offering a higher standard of care, the quality of the U.S. healthcare system can also create barriers to receiving care. For example, the high cost of health care makes it unaffordable for some individuals, leading to an inability to access care. Additionally, patients in rural areas may not have access to specialist care because specialists tend to be concentrated in urban areas. These factors limit the ability of people to access and receive high-quality care.
On the other hand, the quality of U.S. healthcare attracts many patients from other countries who require treatment for complex conditions. For example, people travel from all over the world to receive cancer treatment at world-renowned institutions such as Memorial Sloan Kettering Cancer Center in New York City. U.S. hospitals and clinics are also known for their medical research and innovative treatment options.

Based on the position of the female bladder in relation to the vagina and uterus, what do you think happens to the bladder during the last month of pregnancy? Also be sure to describe where the female bladder is located.
The female b la dder is a muscular, balloon-shaped organ that sits at the bottom of the p el vis, behind the pu bic bone, and in front of the rec tum. It is separated from the ut erus and the va gina by connective tissue.
During pregnancy, the u te rus grows significantly, putting pressure on the b lad der and shifting it upwards towards the abdomen and the belly button. This phenomenon is called "bla d der displacement" or "uterine prolapse" in some instances, as the uterus exerts more pressure on the p el vic region. This can cause a range of symptoms, including frequent urination, urinary incontinence, and an increased risk of urinary tract infections. Pregnant women are also more prone to bladder infections due to the increased pressure on the bl ad der. As the baby drops into the pelvis, the pressure on the b la dder may decrease slightly. However, this is not always the case. The bladder may be pushed to the side of the pe l vis, which can lead to further pressure and discomfort. Overall, during the last month of pregnancy, the bla dder may be under significant stress due to the pressure from the growing u te rus. As a result, it is essential for pregnant women to drink plenty of water and empty their bladder frequently to prevent any complications.

What two anatomical structures would be at risk of complications
from Aortic Stenosis?
Aortic Stenosis is a medical condition that affects the heart valve. The aortic valve, located between the left ventricle and the aorta, is normally a one-way valve that allows blood to flow from the left ventricle into the aorta.
The most common cause of aortic stenosis is calcification or hardening of the valve, which can lead to a narrowing of the valve opening. This narrowing can result in two anatomical structures that are at risk of complications, which are:1. Left ventricle: The left ventricle is the heart's main pumping chamber, and it is the most likely structure to be affected by aortic stenosis.
When the valve narrows, the left ventricle has to work harder to pump blood through the valve. This increased workload can lead to the left ventricle becoming thicker and stiffer, a condition known as left ventricular hypertrophy (LVH). LVH can cause chest pain, shortness of breath, fatigue, and even heart failure.
2. Aorta: The aorta is the body's largest artery and carries oxygen-rich blood from the heart to the rest of the body. When the aortic valve is narrowed, the aorta has to work harder to push blood through the valve. This can cause the aorta to become enlarged (dilated), a condition known as aortic aneurysm. An enlarged aorta can be life-threatening if it ruptures or dissects (tears).In conclusion, two anatomical structures at risk of complications from Aortic Stenosis are the left ventricle and the aorta.

A prime mover (agonist) is the name given to a muscle producing the majority of the ____________ during a joint movement.
A prime mover, also called an agonist, is a muscle that is primarily responsible for generating the force required for joint movement. When it contracts, it produces a concentric contraction, shortening and tightening the muscle fibers. This movement is essential for generating the force required for the joint to move through its range of motion.
Prime movers work together with other muscle groups, such as synergists and antagonists, to create a coordinated movement. The prime mover works by creating the initial movement, while the synergists work to stabilize the joint, and the antagonists work to slow down or stop the movement.
There are various muscles in our body, which work as prime movers or agonists. For instance, the biceps are prime movers in elbow flexion, while the triceps are prime movers in elbow extension. The quadriceps are prime movers in knee extension, while the hamstrings are prime movers in knee flexion.
The pectoralis major is a prime mover in shoulder flexion, while the latissimus dorsi is a prime mover in shoulder extension. The prime mover or agonist is an essential muscle that generates the majority of the force during joint movement. Without it, it would be challenging to produce coordinated movements and execute daily activities like walking, running, and lifting objects.

Another type of adaptive immune cell can recognize viral infected cells and attack them directly with perforins and granzymes. It recognized the infected cell due to the presence of viral proteins on the cell surface of the infected mucosa cells bound to a MHC class I molecule.
Adaptive immune cells are the components of the immune system that learn to respond to specific antigens over time. Unlike the innate immune response, which is instant and generic, the adaptive immune system takes time to adapt to a new challenge. When the immune system recognizes a foreign substance, specialized cells are activated that target that specific substance. These cells include B cells and T cells, as well as macrophages, dendritic cells, and other cells that help to identify and target pathogens.
A key feature of the adaptive immune system is the ability to form memory cells that can recognize a particular antigen years after it was last encountered. This allows for rapid and efficient responses to repeat infections by the same pathogen. There are two primary types of adaptive immune cells: B cells and T cells. Each type of cell plays a specific role in recognizing and targeting specific pathogens and foreign substances.

Three care managers at Quadrangle Sunrise Senior Living Center, a 143-bed facility in Pennsylvania, were charged with aggravated assault, simple assault, criminal conspiracy, harassment, neglect of a care-dependent person, and related crimes for taunting and physically abusing Lois McCallister, a 78-year-old dementia patient, for 12 minutes and blocking her door when she tried to escape. McCallister's family contacted Quadrangle administrators in March after she complained of being punched and slapped, but said they were told the allegations were products of McCallister's dementia. The relatives then installed a camera disguised as a clock in her room and turned over the resulting video to police.
1) Was there corporate negligence in this case? Apply the 4 legal elements of negligence to the facts for the "corporation" following my feedback from Week 2. Note: I'm NOT asking about the "care managers" here. Make sure your writing follows the format below.
Duty to use due care - (Establish the duty to care and what the duty is)
Standard of care/breach of duty - (describe what the standard of care is and apply the facts to breach of duty)
Injury/actual damages - (apply the facts - what are the injuries/damages in this case)
Causation - (apply the facts by discussing both but for causation and foreseeability)
2) Assume that the court found no direct corporate negligence. What other legal theory could Quadrangle be held liable under?
3) Think about potential liability for its parent company, Sunrise Senior Living of McLean, Va. Under what circumstances and legal theory could the parent company's governing board be held liable for Quadrangle Sunrise Senior Living Center's negligence?
There may be corporate negligence in this case, as Quadrangle Sunrise Senior Living Center potentially breached its duty of care by failing to address the complaints of abuse made by McCallister's family and dismissing them as products of her dementia. The resulting injuries and damages suffered by McCallister are evident from the video evidence. Causation can be established by showing that, but for the negligence of Quadrangle Sunrise Senior Living Center, McCallister would not have suffered the abuse and harm she did.
Quadrangle Sunrise Senior Living Center had a duty to use due care in providing a safe and appropriate environment for its residents, including McCallister. The duty of care required the facility to reasonably address and investigate any complaints of abuse or mistreatment made by residents or their families. In this case, the family of McCallister contacted Quadrangle administrators in March, reporting allegations of physical abuse. However, the facility failed to adequately respond to these complaints and instead dismissed them as products of McCallister's dementia, thus breaching the duty of care.
The standard of care in this situation would involve promptly investigating and addressing the allegations, ensuring the safety and well-being of the residents. Quadrangle Sunrise Senior Living Center's failure to take appropriate action amounts to a breach of duty.
The injuries and damages suffered by McCallister are evident from the video evidence obtained by her family. The video shows taunting, physical abuse, and the care managers blocking her escape from the room. These actions caused emotional distress, physical harm, and a violation of her rights as a care-dependent person, constituting actual damages.
Causation can be established by demonstrating that the negligence of Quadrangle Sunrise Senior Living Center was the direct cause of McCallister's injuries and damages. But for the facility's failure to address the complaints and take appropriate action, McCallister would not have suffered the abuse and harm she did. Furthermore, it was reasonably foreseeable that neglecting such complaints and allowing abusive behavior to continue could result in harm to the residents.
2) If the court found no direct corporate negligence, Quadrangle could still be held liable under the theory of vicarious liability or respondeat superior. Vicarious liability holds employers responsible for the wrongful acts committed by their employees within the scope of their employment. In this case, the care managers who taunted and abused McCallister were employees of Quadrangle Sunrise Senior Living Center. If their actions were deemed to be within the scope of their employment, Quadrangle could be held liable for their actions, even if the corporation itself was not directly negligent.
3) The parent company, Sunrise Senior Living of McLean, Va., could potentially be held liable for the negligence of Quadrangle Sunrise Senior Living Center under the theory of corporate liability. To establish this, it would need to be shown that Sunrise Senior Living, through its governing board, exercised control over the operations and policies of Quadrangle. If it can be proven that the parent company's governing board had the authority to establish protocols and procedures for addressing complaints of abuse, and failed to do so, resulting in the harm suffered by McCallister, the board could be held liable for the negligence of Quadrangle. However, it is important to consult with legal professionals to evaluate the specific circumstances and applicable laws in order to determine the viability of such a claim.

Explain the historical disparity between sentencing for cocaine vs crack. How did this disparity lead to racial inequalities?
What is the potential relationship between illicit steroid use, mental health and body image?
Is the labeling of psychedelics as a Schedule 1 substance appropriate given what we have learned in this module? Why or why not?
The historical disparity between sentencing for cocaine vs crack: Cocaine and crack cocaine are two different drugs. Cocaine is a powder drug, whereas crack cocaine is made by cooking powdered cocaine, baking soda, and water until it forms a hard rock.
They both have different penalties for the possession, use, and distribution of each drug. When the war on drugs was announced in the 1980s, crack cocaine was labeled as a more harmful drug and received more severe punishments than powder cocaine. In 1986, the United States Congress passed the Anti-Drug Abuse Act, which imposed harsher penalties on crack cocaine crimes than cocaine crimes. The Act set a minimum sentence of 5 years for the distribution of crack cocaine and required a minimum of 100 times the amount of powder cocaine for the same sentence. Due to this difference in sentencing between the two drugs, crack cocaine offenders, who were mostly African American, received longer sentences than cocaine offenders, who were mostly white. Racial inequalities were caused by this disparity because crack cocaine users and dealers were primarily Black, and cocaine users and dealers were primarily white.
The potential relationship between illicit steroid use, mental health, and body image: Illicit steroid use is when people use anabolic-androgenic steroids (AAS) without a doctor's prescription. It's commonly used to increase muscle mass, boost athletic performance, and improve body appearance. The misuse of AAS can lead to mental health and physical problems. AAS can cause mood swings, aggression, paranoia, and delusions. Depression is also a possible outcome of AAS use. The pressure to achieve a perfect body image can lead to steroid use. The media portrays the ideal body image for men as muscular, strong, and lean. Therefore, many men feel compelled to use steroids to achieve this ideal body type.
Labeling of psychedelics as a Schedule 1 substance: Psychedelics are drugs that change perception, mood, thought, and behavior. The Drug Enforcement Administration (DEA) classifies drugs based on their potential for abuse, medical use, and safety. Schedule 1 substances are drugs that have a high potential for abuse, have no medical use, and are unsafe to use. Psychedelics, including LSD and psilocybin, are classified as Schedule 1 substances. The classification is not appropriate since studies have shown that these substances can have medical uses, including treating depression, anxiety, and post-traumatic stress disorder (PTSD). Therefore, the classification should be reconsidered and changed.

Cl: 100 mEq/L
Ca: 8.6 mEq/L
She was diagnosed with heart failure and admitted to the med/Surg unit.
One priority nursing diagnosis for Mrs. K would be Ineffective Breathing Pattern.
Mrs. K is 68 years old and presented to the emergency department with shortness of breath. She was diagnosed with heart failure and admitted to the med/Surg unit. From her assessment, her Neuro reveals that she is anxious, cardiac reveals an elevated heart rate, bounding pulse, and jugular venous distention (JVD), Respiratory shows crackles, dry cough, and dyspnea on exertion (DOE), GU reports decreased urine output and peripheral/neurovascular exhibits +3 pitting edema in bilateral lower extremities. Her vital signs also report low oxygen saturation levels.
Ineffective Breathing Pattern is defined as "inspiration and/or expiration that does not provide adequate ventilation." This diagnosis would be appropriate as it describes Mrs. K's shortness of breath and her other respiratory symptoms. Shortness of breath, along with crackles and dry cough, supports this diagnosis. She also has decreased oxygen saturation, which is a priority concern.
The method of prioritization can be based on Maslow's hierarchy of needs, which is a pyramid of physiological, safety, love/belonging, esteem, and self-actualization needs that are needed for humans to progress. Oxygen is necessary for survival, which falls under the physiological needs category of Maslow's hierarchy of needs.

Fat-soluble vitamins tend to accumulate in the body, and they can be toxic if consumed in large amounts.
Fat-soluble vitamins, such as vitamins A, D, E, and K, can be stored in the liver and other fatty tissues. They are often found in fatty foods, such as butter, oils, and nuts. However, because they are not readily excreted from the body, they can accumulate to toxic levels if they are consumed in excessive amounts. Symptoms of vitamin toxicity can include nausea, vomiting, headaches, and even death.
Therefore, it is important to monitor your intake of fat-soluble vitamins and avoid consuming them in excessive amounts. Water-soluble vitamins, on the other hand, are not stored in the body to the same extent as fat-soluble vitamins. Instead, they are excreted through urine, which means that they need to be consumed on a more regular basis. Examples of water-soluble vitamins include vitamin C and the B vitamins.

Vitamins are either fat-soluble or water-soluble. Fat-soluble vitamins are absorbed with lipids and can accumulate in the body. Water-soluble vitamins are absorbed with water and are not stored in the body.
Explanation:Vitamins can be either fat-soluble or water-soluble. Fat-soluble vitamins (A, D, E, and K) are absorbed through the intestinal tract with lipids in chylomicrons. They are carried in lipids and can accumulate in the body's lipid stores. On the other hand, water-soluble vitamins (including B vitamins and vitamin C) are absorbed with water in the gastrointestinal tract and move easily through bodily fluids. They are not stored in the body and excess amounts are excreted through urine.

Give in detail biomechanical analysis of walking
gait
Biomechanical analysis of walking gait involves studying the movement of the body during walking. It is a quantitative assessment of the motion and muscle activity that occurs when walking.
There are three major phases of walking gait; the stance phase, the swing phase, and the double support phase.The stance phase is when the foot is in contact with the ground. The swing phase is when the foot is off the ground and swinging forward.
The double support phase is when both feet are in contact with the ground, which happens briefly during walking.The biomechanical analysis of walking gait can be used to assess the following parameters; stride length, cadence, step width, and walking speed. Stride length is the distance between two consecutive heel strikes.
Cadence is the number of steps taken per minute. Step width is the distance between the two feet at their widest point during walking. Walking speed is the distance covered per unit time. Biomechanical analysis also involves studying the forces and moments acting on the body during walking.
This includes ground reaction forces, joint moments, and muscle forces. The ground reaction force is the force that is generated by the ground when the foot strikes it. Joint moments are the forces that act on the joints in the body. Muscle forces are the forces that are generated by the muscles to move the body.
The biomechanical analysis of walking gait is useful in identifying any abnormalities or deviations from normal walking. It can be used to assess the effectiveness of treatments for conditions such as cerebral palsy, stroke, and Parkinson's disease. It is also used in the design of prosthetics and orthotics.

The order is for 1000mL of R/L to run at 90mL per hour. The drop factor is 10gtt/mL. How many gtt/min should the IV run?
The IV should run at approximately 900 gtt/min to deliver 1000 mL of R/L over 11.11 hours at a flow rate of 90 mL/hour with a drop factor of 10 gtt/mL.
To calculate the number of drops per minute (gtt/min) for the intravenous (IV) infusion, we need to consider the volume, flow rate, and drop factor. Here's how you can determine the gtt/min:
Calculate the total time of the infusion:
To find the total time in hours, divide the total volume by the flow rate:
Total Time = Volume (mL) / Flow Rate (mL/hour)
In this case, the total time is:
Total Time = 1000 mL / 90 mL/hour = 11.11 hours
Convert the total time to minutes:
Multiply the total time by 60 to convert it to minutes:
Total Time (minutes) = Total Time (hours) * 60
Total Time (minutes) = 11.11 hours * 60 = 666.67 minutes
Calculate the total number of drops:
Multiply the total time (minutes) by the flow rate (mL/hour) and the drop factor (gtt/mL):
Total Drops = Total Time (minutes) * Flow Rate (mL/hour) * Drop Factor (gtt/mL)
Total Drops = 666.67 minutes * 90 mL/hour * 10 gtt/mL = 600,003 gtt
Calculate the gtt/min:
Divide the total number of drops by the total time (minutes):
gtt/min = Total Drops / Total Time (minutes)
gtt/min = 600,003 gtt / 666.67 minutes ≈ 900 gtt/min

Partial plantar Fasciotomy. Preoperative diagnosis: Plantar fasciitis, left foot. Postoperative diagnosis: Plantar fasciitis, left foot. Procedure performed: Partial plantar fasciitis, left foot. Anesthesia: 10 cc of 0.5% Marcaine plain with TIVA. History: This 35-year-old Caucasian female presents to ABCD General Hospital with the above chief complaint. The patient states she has extreme pain with plantar fasciitis in her left foot and has attempted conservative treatment, including orthotics, without long-term relief of symptoms and desires surgical treatment. The patient has been NPO since midnight. Consent is signed and in the chart. No known drug allergies. Details of procedure: An IV was instituted by the Department of Anesthesia in the preoperative holding area. The patient was transported to the operating room and placed on the operating table in supine position with a safety belt across the stomach. Copious amounts of Webril were placed on the left ankle, followed by blood pressure cuff. After adequate sedation by the Department of Anesthesia, a total of 10 cc of 0.5% Marcaine plain was injected into the surgical site both medially and laterally across the plantar fascia. The foot was then prepped and draped in the usual sterile orthopedic fashion. An Esmarch bandage was applied for exsanguination, and the pneumatic ankle tourniquet was inflated to 250 mm Hg. The foot was then reflected on the operating, stockinette reflected, and the foot cleansed with a wet and dry sponge. Attention was then directed to the plantar medial aspect of the left heel. An approximately 0.75-cm incision was then created in the plantar fat pad over the area of maximal tenderness.
The incision was then deepened with a combination of sharp and blunt dissection until the plantar fascia was palpated. A #15 blade was used to transect the medial and central bands of the plantar fascia. Care was taken to preserve the lateral fibroids. The foot was dorsiflexed against resistance as the fibers were released, and there was noted to be increased laxity after release of the fibers on the plantar aspect of the foot, indicating that plantar fascia has in fact been transacted. The air was then flushed with copious amounts of sterile saline. The skin incision was then closed with #3-0 nylon sutures in a simple interrupted fashion. Dressings consisted of #0-1 silk, 4 × 4s, Kling, Kerlix, and Coban. The pneumatic ankle tourniquet was released, and immediate hyperemic flush was noted throughout all digits of the left foot. The patient tolerated the above procedure and anesthesia well without complications. The patient was transported to the PACU with vital signs stable and vascular status intact to the left foot. Intraoperatively, an additional 80 cc of 1% lidocaine was injected for additional anesthesia in the case. The patient is to be non-weight-bearing on the left lower extremity with crutches. The patient is given postoperative pain prescriptions for Vicodin ES, one q3-4, p.o., p.r.n. for pain, as well as Celebrex 200 mg one p.o. b.i.d. The patient is to follow-up with Dr. X as directed.
The procedure performed is a partial plantar fasciotomy for plantar fasciitis in the left foot. The patient received anesthesia, and the surgical site was prepared and draped. An incision was made in the plantar fat pad, followed by dissection to expose the plantar fascia. The medial and central bands of the plantar fascia were transected, preserving the lateral fibroids.
The incision was closed with sutures, and appropriate dressings were applied. The pneumatic ankle tourniquet was released, and the patient's vital signs remained stable. Additional anesthesia was administered intraoperatively, and postoperative pain medications were prescribed.
The procedure described is a partial plantar fasciotomy performed to address plantar fasciitis in the patient's left foot. Plantar fasciitis is a condition characterized by inflammation and pain in the plantar fascia, a thick band of tissue that supports the arch of the foot. When conservative treatments fail to provide long-term relief, surgical intervention, such as a partial plantar fasciotomy, may be considered.
The procedure involved the following steps:
1. Anesthesia: The patient received 10 cc of 0.5% Marcaine plain with TIVA (Total Intravenous Anesthesia).
2. Preoperative preparation: The patient was positioned on the operating table and appropriate safety measures were taken. The surgical site was prepped and draped in a sterile manner.

What is a disadvantage of a cohort study compared to a randomized controlled trial?
a. The external validity is lower
b. It is more prone to selection bias
c. It is less suitable for studying medical outcomes
d. Participants are followed over time to observe disease outcomes
The disadvantage of a cohort study compared to a randomized controlled trial is that it is more prone to selection bias. This statement is option B.
Randomized controlled trials (RCTs) are the gold standard for determining the effectiveness of an intervention or treatment. While cohort studies are also valuable, they have some limitations in comparison to RCTs.Cohort studies are observational studies that track groups of people over time and measure risk factors, exposures, and outcomes. However, they are more prone to selection bias because people can choose whether or not to participate in the study.
In contrast, randomized controlled trials (RCTs) have randomly assigned participants to either the treatment or control group, which minimizes selection bias. In RCTs, the participants are more representative of the general population, and the results are more generalizable. Furthermore, RCTs can assess the causality of the relationship between the intervention and the outcome because of their high internal validity, which is not always possible with cohort studies. However, RCTs can be expensive and impractical in some circumstances.

If the triceps surae, attaching to the calcaneus .04 m from the ankle joint produces 700 N of tension perpendicular to the bone, and the tibialis anterior attaching to the medial cuneiform and base of the first metatarsal .035 m away from the ankle joint exerts 750 N of tension perpendicular to the bone how much net torque is present at the joint? a. 1.75 Nm plantar flexion O b. 17.5 Nm plantar flexion O c. No movement at the joint O d. 17.5 Nm dorsiflexion O e. 1.75 Nm dorsiflexion
The net torque at the joint is option a. 1.75 Nm plantar flexion.
To calculate the net torque at the joint, we need to determine the moment arm for each muscle and then calculate the torque produced by each muscle individually.
The moment arm is the perpendicular distance from the muscle's line of action to the axis of rotation (ankle joint in this case).
Given information:
Triceps surae tension (T1) = 700 N
Triceps surae moment arm (d1) = 0.04 m
Tibialis anterior tension (T2) = 750 N
Tibialis anterior moment arm (d2) = 0.035 m
Torque (τ) is calculated using the formula: τ = T * d, where T is the tension and d is the moment arm.
Torque produced by the triceps surae (τ1) = T1 * d1 = 700 N * 0.04 m = 28 Nm (plantar flexion)
Torque produced by the tibialis anterior (τ2) = T2 * d2 = 750 N * 0.035 m = 26.25 Nm (dorsiflexion)
To calculate the net torque, we subtract the torque produced by dorsiflexion from the torque produced by plantar flexion:
Net torque = τ1 - τ2 = 28 Nm - 26.25 Nm = 1.75 Nm (plantar flexion)
Therefore, the correct answer is option a. 1.75 Nm plantar flexion.

Jody is having trouble seeing close objects, they appear blurry. A trip to the opthamologist indicates Jody’s focal distance is too long. Use this information to answer the following questions.
3A. Based on the information provided, what is Jody’s diagnosis (use the correct term).
3B. Explain why Jody is having trouble seeing close objects clearly - be specific.
3C: Explain how this condition is corrected with glasses/contacts (be complete).
3A. Jody's diagnosis is likely to be "hyperopia" or "farsightedness."
3B. Jody is having trouble seeing close objects clearly because in hyperopia, the focal distance is too long. This means that when light enters the eye, it is focused behind the retina instead of directly on it. As a result, the image of close objects appears blurry.
3C. Hyperopia can be corrected with glasses or contact lenses that have a convex lens. The convex lens helps to bend light rays entering the eye, so that they focus properly on the retina. By wearing glasses or contacts with a positive (convex) lens, the light entering Jody's eye is refracted in a way that compensates for the longer focal distance. This allows the light to converge correctly on the retina, resulting in clear vision for both near and distant objects.
Jody's diagnosis is likely to be "hyperopia," commonly known as farsightedness. In hyperopia, the focal distance of the eye is too long, which means that light entering the eye is not properly focused on the retina. This results in blurred vision, especially when trying to focus on nearby objects.
The trouble in seeing close objects clearly for Jody is due to the way light is refracted by the eye. In a hyperopic eye, the cornea and lens have a flatter curvature than necessary, causing light rays to converge behind the retina instead of directly on it. As a result, the image formed on the retina is out of focus, leading to blurred vision for nearby objects.
To correct this condition, Jody would require glasses or contact lenses with a positive (convex) lens. The convex lens helps to increase the refraction of light entering the eye, compensating for the longer focal length. By wearing these corrective lenses, the light rays are bent in a way that allows them to converge properly on the retina, bringing close objects into focus. This enables Jody to see nearby objects with clarity and improved visual acuity.
It is important to note that the prescription for glasses or contact lenses would be determined by an optometrist or ophthalmologist after conducting a comprehensive eye examination to assess the specific refractive error and visual needs of the individual.
