HESI Fundamentals Study Guide

Correct Answer: A

Rationale: The correct answer is A: Knowledge. In this scenario, the healthcare professional is utilizing knowledge by gathering and applying information about the medication. Choice B, Experience, is not the best option as the focus is on accessing information about the medication rather than personal experience. Choice C, Intuition, refers to a gut feeling or instinct, which is not evident in the scenario. Choice D, Competence, relates more to overall ability and proficiency rather than the specific act of seeking information.

Correct Answer: A

Rationale: The correct answer is A: Serum albumin 3 g/dL. Low levels of serum albumin indicate poor nutritional status and can impair wound healing. Total lymphocyte count, HCT, and HGB levels are not directly related to wound healing and do not pose a significant risk for poor wound healing in this context. Total lymphocyte count reflects the immune status, HCT measures the percentage of red blood cells in blood, and HGB measures the amount of hemoglobin in blood.

Correct Answer: C

Rationale: The correct position for a postoperative client using an incentive spirometer is the Semi-Fowler's position. Placing the client in Semi-Fowler's or high-Fowler's position maximizes lung expansion and the effectiveness of the incentive spirometer. Side-lying may not provide optimal lung expansion. The supine position is not ideal for postoperative clients using incentive spirometers as it may limit lung expansion. The Trendelenburg position is not recommended due to potential complications postoperatively.

Correct Answer: D

Rationale: The correct answer is D because removing the hearing aid before taking a shower is essential to prevent water damage, as moisture can harm the device. Choice A is incorrect because behind-the-ear hearing aids do allow for fine-tuning of volume. Choice B is incorrect because exercise may cause the hearing aid to shift position, so it's important to ensure it stays secure. Choice C is incorrect because hearing a whistling sound when inserting the hearing aid may indicate improper placement or fit.

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.
