Correct Answer: D

Rationale: Elevating the head of the bed to 30 degrees reduces the risk of aspiration by promoting proper digestion and preventing reflux. Warming the formula to room temperature is essential to prevent discomfort and complications. Aspirating and measuring the gastric aspirate is not a recommended nursing action for monitoring enteral feeding via a nasogastric tube, as it can introduce the risk of introducing contaminants into the feeding tube. Therefore, choices A and B are incorrect, making choice D the correct answer.

Correct Answer: A

Rationale: Corrected Rationale: When administering magnesium sulfate to a client with chronic alcoholism, chronic pancreatitis, and hypomagnesemia, the nurse should assess deep tendon reflexes. Magnesium sulfate can depress the central nervous system and decrease deep tendon reflexes, so monitoring them is crucial. Assessing arterial blood gases, skin turgor, or capillary refill time is not directly related to the administration of magnesium sulfate in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Establish requirements. In the procurement process, the initial step involves determining and establishing the requirements for the supplies and equipment needed. This step is crucial as it sets the foundation for the entire procurement process by outlining the specific needs and specifications. Choice A, 'Keep hand receipts up to date,' is not the first step but rather a later administrative task. Choice C, 'Requisition supplies and equipment through the proper channels,' comes after establishing requirements. Choice D, 'Properly receive, inspect, and store required items,' is the final step in the procurement process, focusing on the physical receipt and handling of the procured items.

Correct Answer: A

Rationale: The correct answer is to instruct the client to walk 15 to 20 minutes three times a day. Walking helps improve circulation and reduces the risk of complications following sclerotherapy. Choice B, keeping the legs in the dependent position when sitting, is incorrect as it can increase venous pressure. Choice C, removing compression bandages before going to bed, is incorrect as compression should be maintained as per healthcare provider's instructions. Choice D, performing Berger-Allen exercises four times a day, is incorrect as these exercises may not be specifically recommended post-sclerotherapy.

Correct Answer: A

Rationale: Corrected Rationale: Insulinomas lead to excessive insulin production, causing hypoglycemia. Symptoms of hypoglycemia include nervousness, jitteriness, and diaphoresis. These symptoms result from the low blood sugar levels. Flushed skin, dry mouth, and tented skin turgor (choice B) are more indicative of dehydration. Polyuria, polydipsia, and polyphagia (choice C) are classic symptoms of diabetes mellitus, not insulinomas. Hypertension, tachycardia, and feeling hot (choice D) are not typical symptoms of insulinomas.
