geriatric nursing exam questions with rationale

Correct Answer: C

Rationale: The correct answer is C because drinking hot chocolate before bed contains caffeine which can disrupt sleep. A is correct as exercise can promote better sleep. B is correct as smoking can affect sleep quality. D is correct as reading before bed can help relax the mind.

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. 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: 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 because straining to void can lead to increased vagal stimulation, resulting in decreased blood pressure upon standing (orthostatic hypotension). A: age and walker use don't directly increase risk. C: a leg cast may not directly affect blood pressure. D: Premarin use is not a common cause of orthostatic hypotension.
