HESI Fundamentals Exam
1. Postoperative client with fluid volume deficit. Which change indicates successful treatment?
- A. Decrease in heart rate
- B. Increase in blood pressure
- C. Decrease in respiratory rate
- D. Increase in urine output
Correct answer: A
Rationale: A decrease in heart rate can indicate improved fluid balance and successful treatment of fluid volume deficit. When a client is experiencing fluid volume deficit, the heart rate typically increases as a compensatory mechanism to maintain cardiac output. As fluid volume is restored and the deficit is corrected, the heart rate should decrease back towards a normal range. Choices B, C, and D are less likely to be directly related to the successful treatment of fluid volume deficit. An increase in blood pressure may occur as a compensatory response to fluid volume deficit; a decrease in respiratory rate is not a typical indicator of fluid volume deficit correction; and an increase in urine output can be a sign of improved kidney function but may not directly reflect fluid volume status.
2. A nurse is providing care to a 17-year-old client in the post-operative care unit (PACU) after an emergency appendectomy. Which finding is an early indication that the client is experiencing poor oxygenation?
- A. Abnormal breath sounds
- B. Cyanosis of the lips
- C. Increasing pulse rate
- D. Pulse oximeter reading of 92%
Correct answer: C
Rationale: An increasing pulse rate can be an early sign of poor oxygenation as the body tries to compensate. Abnormal breath sounds (choice A) can indicate respiratory issues, but they may not always be an early sign of poor oxygenation. Cyanosis of the lips (choice B) is a late sign of inadequate oxygenation. A pulse oximeter reading of 92% (choice D) indicates mild hypoxemia but may not be considered an early indication of poor oxygenation.
3. A healthcare professional is preparing to administer 750 mL of 0.9% sodium chloride IV to infuse over 7 hr. The professional should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
- A. 107 mL/hr
- B. 120 mL/hr
- C. 95 mL/hr
- D. 100 mL/hr
Correct answer: A
Rationale: To calculate the infusion rate, divide the total volume (750 mL) by the total time (7 hr). 750 ÷ 7 ≈ 107 mL/hr. Choice A is correct because it accurately calculates the infusion rate based on the total volume and time. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate in this scenario.
4. A client postoperative expresses pain during dressing changes. What should the nurse prioritize?
- A. Administer pain medication 45 minutes before changing the client’s dressing.
- B. Change the dressing less frequently.
- C. Apply a topical anesthetic before removing the dressing.
- D. Use a non-adherent dressing to reduce pain.
Correct answer: A
Rationale: Administering pain medication before changing the dressing is the priority action as it will help alleviate the client's pain and improve comfort. Choice B, changing the dressing less frequently, may hinder proper wound care and healing. Applying a topical anesthetic (choice C) might offer some relief but systemic pain medication is more effective. Using a non-adherent dressing (choice D) can reduce pain during dressing changes, but addressing immediate pain with medication is the most appropriate intervention in this case.
5. What action should be taken to maintain the patency of a peripherally inserted central catheter (PICC)?
- A. Flush the catheter with heparin solution daily.
- B. Change the dressing at the insertion site daily.
- C. Use sterile technique when changing the dressing.
- D. Keep the insertion site dry at all times.
Correct answer: C
Rationale: The correct answer is to use sterile technique when changing the dressing. This practice is essential for preventing infections that can compromise the patency of the PICC line. While flushing the catheter with heparin solution helps prevent clot formation, it does not directly maintain patency. Changing the dressing daily is important for hygiene but does not have a direct impact on catheter patency. Keeping the insertion site dry is crucial to prevent infections but does not specifically address patency maintenance.
