Correct Answer: C

Rationale: In chronic renal failure, proteins should be limited in the diet. When the kidneys are not functioning well, the buildup of protein byproducts can put additional stress on them. Limiting protein intake can help reduce the burden on the kidneys. Carbohydrates and fats do not need to be restricted in the same way as proteins. Vitamins are essential nutrients that should not be limited in the diet unless specified by a healthcare provider for a specific reason.

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: A

Rationale: Correct Answer: Monitoring respiratory status and oxygenation is crucial in clients with lung cancer, as metastasis to the lungs or pleural effusion can compromise breathing. This assessment helps in early identification of respiratory distress and the need for interventions to maintain adequate oxygenation. Choice B is important but not the priority in this situation. Evaluating mental status and cognition should follow after ensuring the client's physiological needs are met. Choice C, checking pain level and providing comfort, is essential but secondary to assessing respiratory status. Choice D, assessing nutritional status and appetite, is also important but not the priority when the client's breathing is at risk.

Correct Answer: C

Rationale: A negative Pap smear does not rule out ovarian cancer, which often requires more comprehensive evaluation, including imaging studies or surgery. The client should be informed that the Pap smear primarily detects cervical cancer, not ovarian cancer. Therefore, further evaluation involving imaging studies or surgery may be necessary to determine the presence of ovarian cancer. Choice A is incorrect because a Pap smear is not sufficient to detect ovarian cancer. Choice B is incorrect because surgery may be necessary for further evaluation if ovarian cancer is suspected. Choice D is incorrect because further tests are needed to confirm or rule out ovarian cancer.
