geriatric nursing exam questions with rationale

Correct Answer: A

Rationale: The correct answer is A because it accurately reflects the multifactorial nature of diabetes in older adults. Age-related changes, coupled with lifestyle factors like poor diet and lack of exercise, contribute to the high incidence of diabetes in this population. This statement acknowledges the complexity of diabetes in older adults. B is incorrect because while nurses should have knowledge about diabetes in older adults, the statement does not specifically address the multifactorial nature of the disease in this population. C is incorrect because ethnicity can indeed play a role in diabetes risk and should not be dismissed outright. D is incorrect because the development of diabetes is not considered a normal age-related change; it is a medical condition that can be influenced by various factors.

Correct Answer: C

Rationale: The correct answer is C: Certified gerontological nurse. This nurse has specialized knowledge and training in caring for elderly patients, aligning with the nursing home's focus on eldercare standards. Certification demonstrates expertise in gerontological nursing. A: A nurse from a certified college may not necessarily have specialized training in gerontological nursing. B: Experience is valuable, but without specific gerontological training, the nurse may lack the specialized skills required for eldercare. D: A gerontological nurse practitioner has advanced training, but for direct patient care in a nursing home setting, a certified gerontological nurse may be a better fit.

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: 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 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.
