HESI Practice Test for Fundamentals

Correct Answer: C

Rationale: At 0100 on the client's second postoperative night, the nurse should address the client's inability to sleep. Providing a prescribed PRN sedative-hypnotic is appropriate in this situation to help the client rest. Choice A is incorrect because leaving the room and closing the door does not directly address the client's sleep concern. Choice B is not the priority at this moment since the client's main issue is insomnia, not pain. Choice D, while encouraging a non-stimulating activity, does not provide immediate relief for the client's sleeplessness as a sedative-hypnotic would.

Correct Answer: A

Rationale: When a client is receiving 100% oxygen via a partial rebreathing mask, there is a higher risk for oxygen toxicity due to the higher concentration of oxygen delivered. This client should be assessed most frequently for manifestations of oxygen toxicity. Choices B, C, and D are less likely to result in oxygen toxicity compared to 100% oxygen delivery via a partial rebreathing mask.

Correct Answer: D

Rationale: The correct answer is D. If a client reports developing a rash when taking a specific medication, even if they are not aware of any allergies, it is crucial to document this information. This is necessary to prevent future allergic reactions. Identifying the exact medication that caused the rash is essential as the client could have an allergy to it. Providing this information allows healthcare providers to avoid prescribing the same medication again, which could potentially lead to more severe allergic reactions or life-threatening situations. Choices A, B, and C are incorrect because they do not address the importance of documenting the specific medication that caused the adverse reaction or the potential risks of repeating the medication. Simply attributing the rash to common occurrences, adverse effects of medications in general, or assuming the rash is insignificant in the current context can overlook the critical aspect of identifying and avoiding allergens.

Correct Answer: A

Rationale: The correct first step in using a fire extinguisher is to remove the safety pin. This action enables the extinguisher to be activated and used effectively. Choice B, aiming the extinguisher at the base of the fire, comes after removing the safety pin. Choice C, squeezing the handle to release the extinguishing agent, and choice D, sweeping the extinguisher from side to side, are subsequent steps in using a fire extinguisher and should follow removing the safety pin.

Correct Answer: A

Rationale: To prevent complications associated with prolonged bed rest, encouraging the client to perform antiembolic exercises every 2 hours is essential. These exercises help promote circulation and prevent blood clots. Instructing the client to cough and deep breathe every 4 hours is beneficial for respiratory function, but it is not as critical as antiembolic exercises. Repositioning the client every 4 hours helps prevent pressure ulcers and maintain skin integrity. Restricting fluid intake is not recommended, as hydration is important for overall health and well-being, especially for clients on bed rest.
