geriatric nursing exam questions with rationale

Correct Answer: D

Rationale: The correct answer is D: Serum triiodothyronine (T3) and gastric pepsin. Aging typically leads to a decrease in serum T3 levels due to reduced thyroid function. Gastric pepsin production also decreases with age, impacting digestion. A: Creatinine clearance and insulin secretion typically decrease with kidney and pancreatic function decline, not necessarily solely due to aging. B: Blood CO2 levels and saliva production are not directly affected by aging but can be influenced by various health conditions. C: Left ventricle-wall thickness may increase with age due to conditions like hypertension, and skin healing time can be affected by various factors other than just aging. In summary, the correct answer stands out as age-related declines in serum T3 and gastric pepsin levels are more directly linked to the aging process compared to the other choices.

Correct Answer: B

Rationale: The correct answer is B: Fewer taste buds. As people age, they tend to have fewer taste buds, leading to a decreased ability to taste food. This can result in a loss of interest in eating, which may contribute to anorexia and weight loss. Excessive saliva (A) does not directly contribute to anorexia or weight loss. Wearing dentures (C) may affect chewing but is not a major factor in anorexia. Softened tooth enamel (D) is more related to dental health rather than appetite and weight loss.

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.

Correct Answer: C

Rationale: Correct Answer: C - Maintain blood pressure below 120/70 mm Hg. Rationale: 1. Older African American individuals are at higher risk for hypertension. 2. African American men have a higher prevalence of hypertension compared to other demographic groups. 3. Hypertension is a common health issue among Jamaican individuals. 4. Keeping blood pressure below 120/70 mm Hg helps prevent complications like stroke and heart disease. Summary: A. Attributing illness to voodoo is culturally inappropriate and lacks evidence-based practice. B. Improving social relationships may be beneficial but is not directly related to the man's health needs. D. Reviewing magicoreligious systems is not relevant to addressing the man's health issues like hypertension.
