Correct Answer: A

Rationale: The correct answer is A: Question the client about the frequency of falls. In the elderly population, falls are a significant risk factor that can impact their functional abilities and safety. By assessing the frequency of falls, the nurse can identify potential risks and implement interventions to prevent future falls. Choices B, C, and D are incorrect because they do not directly address the primary focus of a functional assessment for nursing home care, which is to evaluate the client's functional status and identify areas that may require assistance or intervention.

Correct Answer: B

Rationale: The correct recommendation for managing chemotherapy-induced fatigue is to advise the client to rest when needed and maintain a balanced diet. Increasing the dose of chemotherapy (Choice A) would exacerbate the fatigue and other side effects. While light physical activity (Choice C) can be beneficial, extreme fatigue may require more rest initially. Delaying chemotherapy treatment (Choice D) should only be considered after consultation with the healthcare provider, as timely treatment is usually crucial in cancer care.

Correct Answer: C

Rationale: A serum creatinine level of 0.3 mg/dL is abnormally low, indicating potential issues with the interpretation of the creatinine clearance test. It is crucial for the nurse to notify the healthcare provider of this result before proceeding with the 24-hour urine collection. Checking urine output, instructing the client to increase fluid intake, or starting the urine collection without consulting the healthcare provider could lead to incorrect test results and misinterpretation of the client's renal function.

Correct Answer: B

Rationale: The correct answer is B: 'Murmur.' A murmur is a swishing sound heard during auscultation, typically caused by turbulent blood flow through the heart or valves. Choices C and D, 'S3 sound' and 'S4 sound,' refer to specific heart sounds associated with different cardiac conditions, not the general description of a swishing sound. Choice A, 'Heart murmur,' is redundant as 'murmur' alone is sufficient to describe the swishing sound heard.

Correct Answer: B

Rationale: An oxygen saturation of 88% indicates hypoxemia, which is a critical condition requiring immediate intervention to improve oxygenation. Hypoxemia can lead to tissue hypoxia and further complications. A productive cough with yellow sputum is common in pneumonia but may not require immediate intervention unless it worsens or is associated with other concerning symptoms. A respiratory rate of 20 breaths per minute is within the normal range, indicating adequate ventilation. A heart rate of 90 beats per minute is also within a normal range and may not require immediate intervention unless it is accompanied by other abnormal findings.
