HESI Fundamentals Study Guide

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: Assigning an admission with atrial fibrillation and heart failure to a PN is not appropriate. This complex case requires more advanced skills and should not be managed by a PN without adequate support. The PN may not have the necessary training or expertise to handle such a critical situation effectively. Choice B is a suitable assignment for a PN nursing student as they can handle a client who had a major stroke 6 days ago. Choice C is also appropriate as a child with burns receiving packed cells and albumin IV running can be managed by the charge nurse. Choice D is within the scope of practice for a UAP since an elderly client post-myocardial infarction a week ago may require basic care and assistance.

Correct Answer: C

Rationale: To administer 250 mL over 30 min with a drop factor of 10 gtt/mL, the healthcare professional should adjust the IV infusion to deliver 100 gtt/min. The correct calculation is: (250 mL � 30 min) x 10 gtt/mL = 100 gtt/min. This rate ensures the proper administration of the IV solution within the specified time frame. Choices A, B, and D are incorrect as they do not align with the accurate calculation based on the provided data.

Correct Answer: D

Rationale: The correct answer is to initiate contact precautions when providing client care. C-diff (Clostridium difficile) is highly contagious, and contact precautions are necessary to prevent its spread. Giving the client chlorhexidine gluconate for hand hygiene (Choice A) is not specific to managing C-diff. Removing the protective gown first when exiting the client's room (Choice B) may increase the risk of contaminating oneself and the environment. Using alcohol-based hand rub when caring for the client (Choice C) is not sufficient to prevent the transmission of C-diff, as soap and water are more effective against this particular pathogen.

Correct Answer: C

Rationale: To assess for orthostatic hypotension, a healthcare professional needs to obtain a blood pressure cuff. Orthostatic hypotension is defined as a drop in blood pressure greater than 20 mm Hg in systolic pressure or 10 mm Hg in diastolic pressure when moving from lying down to a standing position. A thermometer (Choice A) is used to measure body temperature and is not directly related to assessing orthostatic hypotension. Elastic stockings (Choice B) are used for preventing deep vein thrombosis and improving circulation in the lower extremities, not for assessing orthostatic hypotension. Sequential compression devices (Choice D) are mechanical pumps that are used to prevent deep vein thrombosis and are not specifically used for assessing orthostatic hypotension.
