Correct Answer: D

Rationale: Sudden loss of consciousness in a client with a suspected stroke is the most concerning finding as it indicates a more severe neurological event, such as brain stem involvement or hemorrhage, requiring immediate intervention. While unilateral facial droop, slurred speech, and weakness in one arm are all common signs of a stroke, sudden loss of consciousness signifies a critical condition that needs urgent attention and evaluation to prevent further complications.

Correct Answer: C

Rationale: The correct answer is C. Abdominal rigidity in a client with a bowel obstruction could indicate peritonitis, a serious complication requiring immediate attention. Volvulus, a twisting of the intestine, can lead to bowel ischemia and necrosis. Clients with pneumonia (choice A) may need assessment and treatment for infection, but it is not as immediately life-threatening as a bowel obstruction. A client who underwent knee surgery (choice B) needing a dressing change can typically wait for assessment compared to a potential surgical emergency. Similarly, a client with diabetes requesting insulin (choice D) may require attention to maintain blood glucose levels, but it is not as urgent as a suspected bowel obstruction with possible peritonitis.

Correct Answer: A

Rationale: Weight-bearing exercises are crucial in managing osteoporosis as they help strengthen bones. Choice A is the correct answer because weight-bearing activities, such as walking, dancing, or weight training, help stimulate bone formation and strengthen bones, which is essential in managing osteoporosis. Choice B is incorrect as the primary focus should be on the type of exercise rather than weight reduction. Choice C is incorrect because avoiding exercise altogether can lead to further bone density loss, and it is important to engage in safe weight-bearing activities. Choice D is incorrect as the primary goal of exercise in osteoporosis is to improve bone density through weight-bearing activities.

Correct Answer: B

Rationale: Verifying the correct placement of a nasogastric tube before each feeding is essential to prevent aspiration and ensure that the tube is properly positioned in the stomach or intestine. This action is a priority to maintain client safety. Flushing the tube with water every 4 hours is important for tube patency but is not the priority over verifying placement. Securing the tube with tape and keeping the head of the bed elevated are crucial but are considered secondary measures compared to confirming the correct tube placement.

Correct Answer: A

Rationale: In a client receiving continuous ambulatory peritoneal dialysis (CAPD) who has lost weight and exhibits increasing edema, the nurse should prioritize evaluating the patency of the arteriovenous (AV) graft. This assessment is crucial to determine if hemodialysis can be resumed, addressing the client's presenting issues effectively. Instructing the client to continue a fluid-restricted diet (choice B) may not address the underlying issue related to the CAPD. Recommending support stockings for venous return (choice C) is not directly relevant to the situation described. Monitoring the client's serum albumin levels (choice D) may be important but does not directly address the immediate concern of weight loss and increasing edema in a CAPD client.
