HESI RN CAT Exit Exam
1. The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?
- A. Blood glucose of 140 mg/dL
- B. White blood cell count of 8000/mm³
- C. Serum potassium of 3.8 mEq/L
- D. Serum calcium of 7.8 mg/dL
Correct answer: D
Rationale: The correct answer is D. A serum calcium level of 7.8 mg/dL requires immediate intervention due to the risk of hypocalcemia. Hypocalcemia can lead to serious complications such as tetany, seizures, and cardiac arrhythmias. The other laboratory findings are within normal limits or slightly elevated, which do not pose an immediate threat to the client's health in this scenario.
2. Which of the following is not a barrier method of birth control?
- A. Vaults
- B. Diaphragms
- C. Sterilization
- D. Cervical caps
Correct answer: C
Rationale: The correct answer is C, Sterilization. Sterilization is a permanent form of birth control that involves surgical procedures to prevent pregnancy by blocking the fallopian tubes or vas deferens. Barrier methods physically prevent sperm from reaching the egg, such as vaults, diaphragms, and cervical caps. These devices create a barrier to sperm, unlike sterilization. Therefore, choices A, B, and D are all considered barrier methods of birth control.
3. A client is being monitored while receiving bethanechol chloride (Urecholine) for urinary retention. Which of the following indicates a therapeutic effect of this medication?
- A. Increased heart rate
- B. Increased peristalsis
- C. Passage of flatus
- D. Urinary output of 50 mL per hour
Correct answer: D
Rationale: Bethanechol chloride (Urecholine) is administered to stimulate the bladder and treat urinary retention. The therapeutic effect is indicated by an increased urinary output, as it demonstrates the medication's ability to prompt the bladder to empty. Increased heart rate and passage of flatus are unrelated to the therapeutic effects of bethanechol. Although bethanechol can increase peristalsis, the primary therapeutic goal is to address urinary retention.
4. A nurse is planning a community event to raise awareness about mental health. Which activity should be included to best engage participants?
- A. lectures by mental health professionals
- B. interactive workshops on stress management
- C. distribution of mental health resources
- D. screenings for depression and anxiety
Correct answer: B
Rationale: Interactive workshops on stress management should be included to best engage participants in a community event about mental health. Unlike lectures by mental health professionals, workshops actively involve participants, allowing for interaction and practical skill-building. While distributing mental health resources and providing screenings for depression and anxiety are important components, interactive workshops offer a more engaging and hands-on approach, empowering individuals with skills they can use to manage their mental health effectively.
5. A client with cirrhosis is receiving lactulose. What is the most important assessment for the nurse to monitor?
- A. Monitor the client's ammonia levels.
- B. Monitor the client's blood glucose level.
- C. Monitor the client's potassium levels.
- D. Monitor the client's level of consciousness.
Correct answer: D
Rationale: The correct answer is to monitor the client's level of consciousness. Lactulose is used to reduce ammonia levels in hepatic encephalopathy. Monitoring the level of consciousness helps assess the effectiveness of lactulose therapy in improving the client's condition. Monitoring ammonia levels (choice A) is important, but assessing the client's response to therapy through their level of consciousness is more crucial. Blood glucose levels (choice B) and potassium levels (choice C) are not directly related to lactulose therapy for cirrhosis and hepatic encephalopathy.
