Researchers hypothesize that most super-centenarians survive and are in good health due to which of the following factors?

Correct Answer: C

Rationale: The correct answer is C because it states that the exact cause of super-centenarians' longevity and good health is not known. This acknowledges the uncertainty and complexity of the situation, highlighting the need for further research and understanding. Explanation for why the other choices are incorrect: A: Genetic makeup alone may not fully explain super-centenarians' survival, as there are likely additional factors involved. B: Living in wealthier areas does not guarantee longevity or good health, as there are many other factors at play. D: While quality medical care and improved social conditions can contribute to health, they are not the sole reasons for super-centenarians' exceptional longevity.

Correct Answer: D

Rationale: The correct answer is D: Depression. Depression is a strong predictor of functional decline in older adults because it can lead to decreased motivation, social withdrawal, and physical symptoms that affect daily activities. Depression is also associated with cognitive impairment, which can further impact functioning. Being physically active (A) and high socioeconomic status (B) are generally positive factors for maintaining function. Advanced age (C) alone is not a strong predictor of functional decline compared to depression.

Correct Answer: B

Rationale: The correct answer is B. Checking postural blood pressures is essential to assess for orthostatic hypotension in an elderly client with a history of falls and hypertension medication. Orthostatic hypotension can lead to falls, so monitoring postural B/Ps is crucial. Checking B/P every 2 hours (choice A) is not necessary and could cause unnecessary discomfort to the client. Checking serum sodium levels (choice C) and serum creatinine levels (choice D) are not directly related to the client's risk factors for falls post-prostate surgery.

Correct Answer: B

Rationale: Postural hypotension is a drop in blood pressure when standing up. Increased cholesterol levels do not directly affect blood pressure regulation or lead to postural hypotension. Medications, decreased baroreceptor sensitivity, and arterial stiffness can all contribute to postural hypotension by affecting blood pressure regulation mechanisms. Therefore, choice B, increased cholesterol level, is the correct answer as it does not directly cause postural hypotension.

Correct Answer: C

Rationale: The correct answer is C: Medications and polypharmacy. In older adults, incontinence is commonly caused by medications that affect bladder control, such as diuretics, sedatives, and anticholinergics. Polypharmacy can worsen this by increasing the likelihood of drug interactions. Chronic urinary tract infections (A) can cause incontinence but are less common in older adults. Neurological disorders (B) like dementia or stroke can also lead to incontinence but are not the most common cause. Poor hydration (D) can exacerbate incontinence but is not the primary cause.

Correct Answer: B

Rationale: The correct answer is B: Magicoreligious. This belief involves attributing illness to supernatural forces or divine punishment. In this scenario, the patient's statement implies a belief that her illness is a result of angering God, indicating a magical or religious explanation. Choice A (Biomedical) focuses on scientific and physical causes of illness, which is not reflected in the patient's statement. Choice C (Naturalistic) involves viewing illness as a part of the natural world, without supernatural elements. Choice D (Ayurvedic) is a traditional Indian system of medicine and does not relate to the patient's belief in supernatural punishment.

Correct Answer: B

Rationale: The correct answer is B because using large size fonts on written material is important for elderly individuals in assisted living facilities who may have visual impairments. This accommodation ensures that the residents can easily read and understand the information being presented. This is crucial for effective communication and engagement in the educational program. A: While using simple language is generally beneficial, the primary concern for this specific population is visual accessibility rather than language complexity. C: Providing the program in a quiet area is important for minimizing distractions, but it is not as critical as ensuring the residents can read the material. D: While building on prior knowledge is a good practice in teaching, it is secondary to ensuring that the information is visually accessible to the residents.

Correct Answer: D

Rationale: The correct answer is D. Intermittent claudication, defined as pain in the lower extremities with walking that improves with rest, is a classic symptom of moderate to severe PAD. This occurs due to inadequate blood flow to the muscles during exercise. Other choices are incorrect: A is typically associated with syncope or fainting; B is more indicative of cardiovascular or pulmonary issues; and C is more commonly seen in mesenteric ischemia.

Correct Answer: B

Rationale: The correct answer is B: Low calcium intake. Osteoporosis is a condition characterized by weakened bones, making them more susceptible to fractures. Calcium is essential for bone health, and a low intake can lead to decreased bone density and increased risk of osteoporosis. Physical activity, while beneficial for overall health, is not a significant risk factor for osteoporosis. High alcohol consumption can contribute to bone loss but is not as significant as low calcium intake. Genetics play a role in predisposing individuals to osteoporosis, but it is not a modifiable risk factor like low calcium intake. Thus, B is the correct answer.
