Practice HESI Fundamentals Exam
1. A client with a history of hypertension is prescribed a diuretic. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?
- A. Monitor serum calcium levels.
- B. Monitor serum potassium levels.
- C. Monitor serum sodium levels.
- D. Monitor serum magnesium levels.
Correct answer: B
Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.
2. A 3-year-old child has had multiple tooth extractions while under general anesthesia. The client returns from the post-anesthesia care unit crying but awake. Which approach is likely to be successful?
- A. Examine the mouth first
- B. Reassure the child
- C. Examine the mouth last
- D. Offer a pacifier
Correct answer: C
Rationale: In this scenario, it is crucial to prioritize the comfort of the child. By examining the mouth last, discomfort is minimized, and the child is given the opportunity to settle down. Choosing to examine the mouth first may escalate the distress of the child further. While reassuring the child is important, in this case, addressing the physical discomfort before providing emotional reassurance is more effective. Offering a pacifier may provide some comfort, but addressing the immediate physical discomfort by examining the mouth last is the most appropriate action to help the child settle down after the procedure.
3. When reviewing a client’s fluid and electrolyte status, what should the nurse report to the provider?
- A. Potassium 5.4
- B. Sodium 140
- C. Calcium 8.6
- D. Magnesium 2.0
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.
4. When caring for an older adult client who becomes agitated when asked to remove dentures before surgery, which of the following responses should the nurse make?
- A. "What worries you about being without your teeth?"
- B. "You need to follow the preoperative instructions and remove your dentures."
- C. "It's important to remove dentures to ensure proper fitting of the mask during anesthesia."
- D. "I will explain why dentures need to be removed before surgery."
Correct answer: A
Rationale: The correct response is to ask the client about their concerns regarding being without their teeth. This approach helps address the client's anxiety and provides insight into the reason for their agitation. Choice B is authoritarian and does not address the client's emotional needs. Choice C focuses on the technical aspect of surgery and does not address the client's emotional state. Choice D implies a one-way communication without addressing the client's feelings or concerns.
5. A nurse is providing home care for a client who is receiving tube feedings and medication through a gastrostomy tube. The family member providing the feedings reports that the client has begun to have diarrhea. For which of the following practices should the nurse intervene?
- A. The family member washes out the feeding bag with warm water once every 24 hours.
- B. The family member washes out the feeding bag with hot water once every 24 hours.
- C. The family member washes out the feeding bag with soap and water every 24 hours.
- D. The family member changes the feeding bag every 24 hours.
Correct answer: A
Rationale: The correct answer is A. Washing out the feeding bag with warm water once every 24 hours is not sufficient to prevent bacterial growth and can lead to diarrhea. Using hot water may damage the feeding bag. Washing out the feeding bag with soap and water every 24 hours is excessive and may leave residue that could be harmful. Changing the feeding bag every 24 hours is important for preventing infections but does not directly address the issue of diarrhea in this case.
