HESI Fundamental Practice Exam
1. The healthcare professional is preparing to administer potassium chloride intravenously to a client with hypokalemia. Which action is most important?
- A. Monitor the client's respiratory rate
- B. Check the client's urine output
- C. Administer the potassium chloride as a rapid IV push
- D. Dilute the potassium chloride in an appropriate IV solution
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.
2. While caring for a client receiving parenteral fluid therapy via a peripheral IV catheter, after which of the following observations should the nurse remove the IV catheter?
- A. Swelling and coolness are observed at the IV site.
- B. The client reports mild discomfort at the insertion site.
- C. The infusion rate is slower than expected.
- D. The IV catheter is no longer needed for treatment.
Correct answer: A
Rationale: Swelling and coolness at the IV site can indicate complications such as infiltration, which can lead to tissue damage or fluid leakage into the surrounding tissues. Prompt removal of the IV catheter is essential to prevent further complications. The client reporting mild discomfort at the insertion site is common during IV therapy and does not necessarily warrant catheter removal unless there are signs of infiltration. A slower than expected infusion rate may not always necessitate IV catheter removal; the nurse should troubleshoot potential causes such as kinks in the tubing or pump malfunctions first. Just because the IV catheter is no longer needed for treatment does not automatically mean it should be removed; proper assessment and monitoring for complications are still essential.
3. A charge nurse is explaining the various stages of the lifespan to a group of newly licensed nurses. Which of the following examples should the charge nurse include as a developmental task for a young adult?
- A. Becoming actively involved in providing guidance to the next generation.
- B. Adjusting to major changes in roles and relationships due to losses.
- C. Devoting time to establishing an occupation.
- D. Finding oneself 'sandwiched' between and being responsible for two generations.
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.
4. When assessing a male client, the nurse finds that he is fatigued and is experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client's laboratory values to validate the existence of which condition?
- A. Hyperphosphatemia
- B. Hypocalcemia
- C. Hypermagnesemia
- D. Hypokalemia
Correct answer: D
Rationale: The symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias are indicative of hypokalemia, a condition characterized by low potassium levels. Checking the client's laboratory values for potassium will help confirm this diagnosis. Hyperphosphatemia (Choice A) is an elevated phosphate level in the blood, which is not consistent with the symptoms described. Hypocalcemia (Choice B) is a low calcium level and typically presents with different symptoms than those mentioned in the scenario. Hypermagnesemia (Choice C) is an excess of magnesium in the blood and does not align with the symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias observed in the client.
5. The healthcare provider is caring for a patient with a spinal cord injury and notices that the patient's hips have a tendency to rotate externally when the patient is supine. Which device will the healthcare provider use to help prevent injury secondary to this rotation?
- A. Hand rolls
- B. A trapeze bar
- C. A trochanter roll
- D. Hand-wrist splints
Correct answer: C
Rationale: A trochanter roll is the correct choice as it is used to prevent external rotation of the hips when the patient is in a supine position. Hand rolls (Choice A) are incorrect because they are used to prevent contractures of the fingers, wrist, and hand. A trapeze bar (Choice B) is not the correct option as it helps patients change positions in bed and aids with movement, not specifically for hip rotation. Hand-wrist splints (Choice D) are also incorrect as they are used to maintain the functional position of the wrist and hand, not to address hip rotation.
