geriatric nursing practice questions

Correct Answer: D

Rationale: The correct answer is D, dramatic loss of melanin. Melanin is a pigment responsible for skin color and does not play a role in the development of pressure ulcers. Shearing, decreased body weight, and malnutrition (decreased serum albumin) are all known risk factors for pressure ulcers in the elderly. Shearing can lead to tissue damage, decreased body weight can indicate poor nutrition and muscle wasting, and malnutrition can impair wound healing and skin integrity. Therefore, D is the correct answer as it does not contribute to the likelihood of an elderly person developing a pressure ulcer.

Correct Answer: A

Rationale: The correct answer is A because as individuals age, there is a decrease in renal function leading to reduced renal clearance of drugs. This results in a longer drug half-life and potentially increased drug accumulation in the body. Choice B is incorrect as aging often leads to a decrease in hepatic metabolism, not faster metabolism. Choice C is incorrect because aging can actually lead to reduced gastrointestinal absorption due to changes in the gastrointestinal tract. Choice D is incorrect as aging can result in decreased circulation, which may affect drug distribution negatively.

Correct Answer: A

Rationale: The correct answer is A because social aging refers to changes in a person's roles and relationships as they age. Retiring from a job is a significant social change that typically accompanies aging. This indicates a shift in the man's social status and activities, which aligns with the concept of social aging. B, C, and D are incorrect because taking multiple medications, using a walker, and celebrating a 65th birthday are not direct indicators of social aging. While these factors may be related to aging, they do not specifically address the social aspects of aging, which is the focus of the question.

Correct Answer: B

Rationale: Step 1: Conducting regular reviews allows nurses to assess the necessity and appropriateness of each medication, addressing potential drug interactions, duplications, and side effects in elderly patients. Step 2: This proactive approach helps prevent polypharmacy-related complications and ensures optimal medication management. Step 3: Ensuring medications are taken exactly as directed (A) may not address the root cause of polypharmacy. Recommending over-the-counter medications (C) without proper evaluation can worsen the issue. Administering medications only during hospital stays (D) is not a comprehensive solution outside of the hospital setting.

Correct Answer: C

Rationale: The correct answer is C: Being adequately nourished. Malnutrition weakens the immune system, making individuals more susceptible to infections like tuberculosis. Diabetes (A), living in crowded institutions (B), and immunosuppression (D) all lower immunity, increasing the risk of developing TB. In summary, adequate nutrition is not a risk factor for TB in the elderly, while diabetes, institutional living, and immunosuppression are.
