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: 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: 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.

Correct Answer: D

Rationale: The correct answer is D: For patients 65 years and older to be given sensitive and exemplary care. NICHE aims to provide specialized, high-quality care for older adults through evidence-based practices. This answer aligns with NICHE's goal of improving care quality for elderly patients. Choice A is too restrictive and does not encompass the holistic approach of NICHE. Choice B focuses on cost rather than quality of care. Choice C is vague and does not capture the essence of NICHE's mission to enhance care for older adults.

Correct Answer: A

Rationale: The correct answer is A: Nocturia. Nocturia, or waking up at night to urinate, is a common symptom of benign prostatic hypertrophy (BPH) due to the enlarged prostate pressing on the urethra, causing urinary frequency and urgency. Other symptoms like weak urine stream, difficulty starting urination, incomplete emptying, and dribbling may also be present. Recurrent urinary tract infections (B) are less likely to be the initial symptom of BPH, as they are more commonly associated with urinary retention or obstruction. Functional incontinence (C) is not a typical symptom of BPH, as it is more related to mobility or cognitive issues. Hematuria (D) is not a common presenting symptom of BPH, as it is more indicative of other conditions like urinary tract infections or kidney stones.
