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: 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.

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: A

Rationale: The correct answer is A. Using douches is not recommended as it can disrupt the natural flora and increase the risk of infections. Choices B, C, and D are all correct statements that can help prevent UTIs. Drinking an adequate amount of water helps flush out bacteria, avoiding tight-fitting clothing promotes ventilation and reduces moisture, and wiping from front to back prevents the spread of bacteria from the anal region to the urethra.

Correct Answer: A

Rationale: When a client with diabetes mellitus presents with a high blood sugar level of 320 mg/dL, the nurse's initial action should be to administer sliding scale insulin as prescribed. The priority is to bring down the elevated glucose level promptly to prevent further complications. Encouraging the client to drink fluids or providing a carbohydrate snack would not effectively address the elevated blood sugar level in this scenario. Assessing for signs of hypoglycemia is not appropriate as the client's blood sugar level is high, not low.
