HESI Fundamentals Study Guide

Correct Answer: A

Rationale: The correct answer is A: 'Potassium 5.4'. A potassium level of 5.4 is elevated (normal range is typically 3.5-5.0 mEq/L) and may indicate hyperkalemia, which can have serious cardiac implications. Elevated potassium levels can lead to life-threatening arrhythmias, so immediate reporting and intervention are necessary. Choice B, 'Sodium 140', falls within the normal range (135-145 mEq/L) and does not require immediate reporting. Choice C, 'Calcium 8.6', falls within the normal range (8.5-10.5 mg/dL) and is not an immediate concern. Choice D, 'Magnesium 2.0', is within the normal range (1.5-2.5 mEq/L) and does not need urgent reporting. Therefore, the nurse should prioritize reporting the elevated potassium level as it poses the most immediate risk.

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: 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: Urticaria, also known as hives, is a common manifestation of a mild allergic reaction. It presents as raised, red, itchy welts on the skin. Ptosis is drooping of the upper eyelid and is not typically associated with allergic reactions. Nausea is a gastrointestinal symptom that can occur with various conditions but is not specific to allergic reactions. Hematuria, which is the presence of blood in the urine, is not a typical manifestation of an allergic reaction.

Correct Answer: D

Rationale: The first action the LPN/LVN should implement is to notify the healthcare provider of the family's request. This is crucial to ensure that appropriate steps are taken to address the family's request for hospice care and to coordinate the necessary care for the resident. While reaffirming the client's desire for no resuscitative efforts is important, notifying the healthcare provider takes precedence in this situation. Transferring the client to a hospice inpatient facility and preparing the family for the client's impending death are significant actions but should be done after notifying the healthcare provider to ensure proper coordination of care.
