HESI Fundamentals Practice Questions

Correct Answer: B

Rationale: Fasting can lead to an increased protein-binding response of medications. This can result in a higher concentration of bound medications in the bloodstream, potentially causing toxicity as the medications may not be readily available for metabolism or excretion. Choice A is incorrect because fasting typically doesn't increase medication metabolism. Choice C is incorrect as fasting usually decreases transit time through the intestines. Choice D is incorrect since fasting generally does not decrease medication excretion.

Correct Answer: A

Rationale: When a client with a terminal illness asks about advance directives, it is essential to provide the information they seek. Choice A is the correct response as it acknowledges the client's request and offers to discuss advance directives while providing additional resources in the form of brochures. This approach empowers the client to make informed decisions about their end-of-life care. Choices B, C, and D are incorrect because they do not directly address the client's request or provide the information the client is seeking. Choice B dismisses the importance of advance directives, which are crucial in end-of-life care planning. Choice C involves the family unnecessarily when the client directly requested information. Choice D deflects the responsibility back to the client to seek information from their provider instead of addressing their immediate request.

Correct Answer: A

Rationale: Abdominal cramping is a common manifestation of hyponatremia (low sodium levels). When sodium levels drop, it can lead to changes in the body's water balance, affecting cell function and causing symptoms like abdominal cramping. Increased thirst (choice B) is more commonly associated with hypernatremia (high sodium levels) due to the body's attempt to dilute the excess sodium. Elevated blood pressure (choice C) and elevated heart rate (choice D) are not typically direct manifestations of low sodium levels and are more commonly seen in conditions like dehydration or shock.

Correct Answer: A

Rationale: The correct answer is A: 'Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.' In the Snellen eye test, a visual acuity of 20/30 means that the client sees at 20 feet what a person with normal vision sees at 30 feet. This indicates that the client's vision is slightly worse than average. Choice B is incorrect as it incorrectly describes the visual acuity of each eye individually, rather than the combined visual acuity. Choice C is incorrect as it misinterprets the meaning of the Snellen eye test results by reversing the values. Choice D is incorrect as it inaccurately describes the visual acuity of the client's eyes, attributing different visual acuities to each eye instead of a combined measurement as indicated by 20/30.

Correct Answer: A

Rationale: In this scenario, the nurse should stand to the side of the patient's eye and observe the cornea. This action is crucial in assessing whether the patient wears contact lenses, especially in unresponsive patients. Observing the cornea can provide valuable information about the patient's eye health and potential use of contact lenses. Choices B, C, and D are incorrect. Concluding that the glasses were lost during the accident is premature without proper assessment. Notifying ambulance personnel about the missing glasses may not be the immediate priority, and asking the unresponsive patient about the glasses would not yield useful information in this situation.
