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: 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.

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: C

Rationale: The correct intervention for a client with diabetes mellitus experiencing tingling in their feet is to teach the client about blood sugar control and foot care. This is essential because tingling in the feet can be a sign of neuropathy, a common complication of diabetes. Educating the client on maintaining proper blood sugar levels and foot care practices can help manage neuropathy symptoms and prevent complications like ulcers or infections. Advising the client to avoid tight shoes (Choice A) may help with comfort but does not address the underlying issue. Referring the client to a podiatrist (Choice B) is important for foot care but does not directly address blood sugar control. Administering insulin (Choice D) is not the priority for managing tingling in the feet related to neuropathy.

Correct Answer: B

Rationale: The correct answer is B: Administer the morphine sulfate as prescribed. In this situation, the client is experiencing symptoms of acute pulmonary edema, a complication of heart failure. Morphine is indicated as it helps reduce anxiety and respiratory distress by decreasing preload and afterload. It dilates blood vessels, reducing the workload of the heart and improving oxygenation. The priority is to administer the morphine promptly to alleviate the client's distress and improve oxygenation. Consulting the charge nurse (A) or reviewing the need for the morphine prescription with the provider (D) would cause a delay in providing essential treatment. Withholding the morphine (C) would not be appropriate as it is indicated for this condition.
