HESI Fundamentals Study Guide

Correct Answer: D

Rationale: The correct action the nurse should take when administering multiple medications to a client with an enteral feeding tube is to flush the tube with 15-30 mL of sterile water before and between medications, and 30-60 mL after the last medication. This helps prevent clogging and ensures each medication is delivered effectively. Choice A is incorrect as medications should not be dissolved in water for administration through an enteral feeding tube. Choice B is incorrect because each medication should be drawn up and administered separately to prevent any potential interactions. Choice C is incorrect as resistance while pushing the plunger may indicate a problem that needs to be addressed before continuing with the administration.

Correct Answer: A

Rationale: The correct answer is A because severe pain can hinder the client's ability to participate effectively in learning. Pain can be distracting and may prevent the client from focusing on acquiring new information or skills. Choice B is incorrect because asking for a demonstration shows an interest in learning and readiness to understand the exercises. Choice C is incorrect as inquiring about potential complications indicates the client's engagement in understanding the procedure and its outcomes, demonstrating readiness to learn. Choice D is incorrect as agreeing to the procedure does not necessarily reflect a lack of readiness to learn. The client may still be open to receiving information about postoperative care, indicating a level of readiness to learn despite agreeing to the surgery.

Correct Answer: A

Rationale: Severe diarrhea can lead to metabolic acidosis due to the loss of bicarbonate. When there is excessive loss of bicarbonate through diarrhea, the pH of the blood decreases, leading to metabolic acidosis. Metabolic alkalosis (Choice B) is not typically associated with severe diarrhea as it involves elevated pH and bicarbonate levels. Hyperkalemia (Choice C) is less likely with severe diarrhea as potassium is often lost along with fluids. Hypercalcemia (Choice D) is not a common complication of severe diarrhea; instead, hypocalcemia may occur due to malabsorption of calcium.

Correct Answer: B

Rationale: The most important initial action for the LPN/LVN to take in this situation is to measure the pulse volume and capillary refill distal to the infiltration. This assessment helps evaluate the severity of the infiltration and the circulation in the affected arm. Asking about past history of drug abuse or addiction (Choice A) is not the priority when addressing acute arm pain and infiltration. Compressing the infiltrated tissue (Choice C) may exacerbate the pain and is not recommended as the first step. Evaluating the extent of ecchymosis (Choice D) is not as critical as assessing the circulation in the affected arm, which is better addressed by measuring pulse volume and capillary refill.

Correct Answer: D

Rationale: The nurse should call the provider for clarification. In situations where there is difficulty reading an order, it is crucial to directly contact the healthcare provider to ensure the correct order is understood and followed. Leaving the order for the oncoming staff (Choice A) may lead to misunderstandings and errors. Contacting the charge nurse (Choice B) may cause delays as they may also need to contact the provider. Asking the pharmacy (Choice C) is not the most direct and immediate action in this scenario, as the provider is the one who can provide immediate clarification.
