geriatric nursing exam questions with rationale

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: B

Rationale: The correct answer is B: Providing palliative care focused on symptom management and comfort. This is the most appropriate intervention for an older adult with advanced heart failure as it prioritizes quality of life by focusing on alleviating symptoms and ensuring comfort. High-dose diuretics (choice A) may lead to electrolyte imbalances and worsen the patient's condition. Initiating aggressive cardiac surgery (choice C) may be too risky and invasive for an older adult with advanced heart failure. Enforcing strict bed rest (choice D) can lead to deconditioning and muscle wasting, further compromising the patient's quality of life.

Correct Answer: B

Rationale: The correct answer is B: Difficulty standing up from a seated position. This is a key indicator of potential sarcopenia because sarcopenia is characterized by age-related loss of muscle mass and strength. Difficulty standing up from a seated position can be attributed to muscle weakness, which is a common symptom of sarcopenia. Unintentional weight loss (A) can be a sign of various health issues, not specific to sarcopenia. Loss of appetite (C) can also be caused by a range of factors, not exclusive to sarcopenia. Increased body fat percentage (D) is not a direct indicator of sarcopenia, as the condition primarily involves muscle loss rather than increased body fat.

Correct Answer: B

Rationale: The correct answer is B because polypharmacy in older adults increases the risk of adverse drug reactions and interactions due to multiple medications being taken concurrently. This can lead to medication errors, decreased adherence, drug toxicity, and increased healthcare costs. Choice A is incorrect as polypharmacy does not improve overall quality of life but rather can negatively impact it. Choice C is incorrect as polypharmacy does not prevent age-related health conditions but can exacerbate them. Choice D is incorrect as polypharmacy has a significant impact on health outcomes in older adults.

Correct Answer: D

Rationale: The correct answer is D because learning advanced knitting techniques adds to the existing knowledge base of older women. This activity stimulates cognitive functioning, enhances problem-solving skills, and fosters creativity. It also helps maintain mental acuity and memory. Choice A is incorrect because although knitting may involve hand movements, it primarily benefits cognitive functions. Choice B is incorrect as the primary focus is on individual learning rather than group cohesion. Choice C is incorrect as the main purpose of the activity is intellectual growth rather than social interaction.
