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.

Correct Answer: D

Rationale: The correct answer is to monitor the client's potassium level. When administering insulin and glucose in hyperkalemia, the aim is to shift potassium from the bloodstream into the cells, lowering elevated levels. Therefore, monitoring potassium levels closely is essential to prevent hypokalemia or further complications. Monitoring blood glucose levels (Choice A) is important but not the priority in this scenario. Monitoring sodium (Choice B) and calcium levels (Choice C) is not directly related to the treatment of hyperkalemia with insulin and glucose.

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: D

Rationale: The correct answer is D: Reduce gastric acid secretion. Omeprazole is a proton pump inhibitor that works by reducing the production of gastric acid in the stomach. This helps in managing GERD by decreasing the acidity levels in the stomach. Choice A is incorrect because omeprazole does not coat the lining of the stomach. Choice B is incorrect as omeprazole does not neutralize stomach acid but rather reduces its production. Choice C is incorrect because omeprazole does not promote gastric motility; instead, it acts on acid secretion.

Correct Answer: B

Rationale: The correct priority action for the nurse to implement in this scenario is to determine the client's need for pain medication. Ensuring that the client is comfortable and free from pain is crucial in end-of-life care, especially for a client with a Do Not Resuscitate (DNR) order. This action prioritizes the client's comfort and dignity in their final moments. While informing the healthcare provider and beginning comfort measures are important aspects of care, pain management takes precedence as the immediate priority. Removing life-saving equipment is not appropriate at this stage as it goes against the client's wishes stated in the DNR order.
