HESI Fundamental Practice Exam

Correct Answer: D

Rationale: The correct answer is to dilute the potassium chloride in an appropriate IV solution. Potassium chloride should never be administered as a rapid IV push as it can lead to severe complications, including cardiac arrhythmias. Diluting the medication and administering it slowly helps reduce the risk of adverse effects. Monitoring the client's respiratory rate (Choice A) and checking urine output (Choice B) are important aspects of patient assessment but not the most crucial when administering potassium chloride. Administering potassium chloride as a rapid IV push (Choice C) is dangerous and can result in serious harm to the client.

Correct Answer: B

Rationale: In this scenario, the nurse should adjust the machine settings. If the electronic blood pressure machine is providing varied intervals and inconsistent readings, it indicates a potential malfunction. Changing the settings may help correct the issue and ensure accurate measurements. Discontinuing the machine and measuring manually every 15 minutes (Choice A) may be time-consuming and impractical. Cleaning the machine (Choice C) is important for routine maintenance but may not address the current issue of varied intervals and inconsistent readings. Increasing the frequency of the readings (Choice D) does not address the problem of inaccurate measurements caused by the malfunctioning machine.

Correct Answer: A

Rationale: When providing mouth care for an unconscious client, the nurse should turn the client's head to the side. This action helps prevent aspiration by allowing any fluids to drain out of the mouth, reducing the risk of choking or aspiration pneumonia. Placing fingers into the client's mouth can be dangerous and may cause injury. Brushing the client's teeth only once a day may not be sufficient for proper oral hygiene care. Injecting mouth rinse into the center of the mouth is not recommended and can potentially lead to aspiration. Therefore, the correct action for the nurse to take is to turn the client's head to the side.

Correct Answer: A

Rationale: The correct answer is A because a second nurse should verify and enter the prescription into the client's medical record to ensure accuracy. This step is crucial to prevent errors in transcription and administration. Choice B is incorrect as having another nurse listen to the phone call does not ensure accurate transcription. Choice C is incorrect because the provider clarifying the prescription upon signing the health record does not replace the need for proper documentation. Choice D is incorrect because the 'read back' process is essential for all telephone prescriptions to confirm accuracy and prevent errors in transcription or administration.

Correct Answer: C

Rationale: The correct answer is C: Devoting time to establishing an occupation. Young adults typically focus on building their careers and personal identities, making establishing an occupation a crucial developmental task for this age group. Choices A, B, and D do not align with the typical developmental tasks of young adults. Choice A relates more to middle adulthood where individuals take on mentoring roles, choice B is more characteristic of the tasks associated with adjusting to late adulthood, and choice D is more relevant to middle adulthood when individuals may find themselves caring for both their own children and aging parents.
