geriatric nursing exam questions with rationale

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: Providing palliative care focused on symptom management and comfort. This is the most appropriate intervention for an older adult with advanced heart failure as it prioritizes quality of life by focusing on alleviating symptoms and ensuring comfort. High-dose diuretics (choice A) may lead to electrolyte imbalances and worsen the patient's condition. Initiating aggressive cardiac surgery (choice C) may be too risky and invasive for an older adult with advanced heart failure. Enforcing strict bed rest (choice D) can lead to deconditioning and muscle wasting, further compromising the patient's quality of life.

Correct Answer: A

Rationale: The correct answer is A: Role theory. Role theory suggests that individuals continue to seek fulfilling roles and activities in older age to maintain a sense of purpose and identity. In this scenario, the older woman's transition from a career as a school principal to volunteering at the library aligns with the idea of seeking meaningful roles. B: Disengagement theory posits that older adults withdraw from society as they age, which contradicts the woman's active engagement in volunteering. C: Age-stratification theory focuses on how age influences opportunities and constraints within society, not on individual choices like volunteering. D: Social exchange theory emphasizes reciprocal relationships and benefits gained from social interactions, which is not the primary focus in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Coordinating care among healthcare providers. This is the most important consideration for providing care to older adults with multiple chronic conditions because it ensures that all aspects of their health are managed comprehensively and efficiently. Coordinating care among healthcare providers helps prevent medication interactions, duplicate tests, and conflicting treatment plans. It also promotes better communication and collaboration among the healthcare team, leading to improved outcomes for the patient. A: Treating each condition independently is not ideal as it may result in conflicting treatment plans and overlook the holistic nature of managing multiple chronic conditions. B: Using a single medication for all conditions is not appropriate as different conditions may require specific medications tailored to each individual's needs. D: Limiting social interactions to reduce stress is not directly related to managing multiple chronic conditions and may have negative effects on the overall well-being of the older adults.

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.
