HESI Fundamentals Study Guide

Correct Answer: A

Rationale: The correct answer is A. It is crucial for the client to remove the hearing aid before showering to prevent damage from moisture. Choice B is incorrect as wearing the hearing aid all the time, including during sleep, is not recommended and can cause discomfort or harm. Choice C is incorrect as alcohol can damage hearing aids; they should be cleaned with a solution recommended by the manufacturer to prevent harm. Choice D is incorrect because hearing aids should not be turned off when not in use; instead, they should be stored properly following the manufacturer's instructions to maintain functionality and battery life.

Correct Answer: A

Rationale: The correct answer is A: Hypotension. Heat stroke is characterized by elevated body temperature, which can lead to hypotension (low blood pressure) due to dehydration and vasodilation. Bradycardia (slow heart rate) and clammy skin are not typical findings in heat stroke. Bradypnea (slow breathing) is also not a common feature of heat stroke. Therefore, hypotension is the most likely cardiovascular manifestation seen in a client with heat stroke.

Correct Answer: A

Rationale: The correct answer is A. Washing out the feeding bag once every 24 hours with warm water can lead to bacterial growth due to inadequate cleaning, potentially causing diarrhea. Hot water, as in choice B, can also promote bacterial growth, which is not desirable. Changing the feeding bag every 48 hours, like in choice C, is within an acceptable timeframe and is unlikely to be a cause of diarrhea. Adding water to the formula before administration, as in choice D, is a common practice to dilute the formula but is not typically associated with causing diarrhea in this scenario.

Correct Answer: A

Rationale: In a situation where a client is found unresponsive on the floor, the nurse's first priority is to establish an airway. This is crucial to ensure that the client can breathe adequately and receive oxygen. Without a patent airway, the client's oxygenation and ventilation may be compromised, leading to serious consequences. Calling for assistance is important, but establishing an airway takes precedence as it directly impacts the client's ability to breathe. Checking the client's pulse and blood pressure can be done after ensuring a clear airway. Performing CPR is not the immediate action needed unless the client's breathing and pulse are absent after the airway has been secured.

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.
