HESI RN
HESI Medical Surgical Practice Exam
1. During spring break, a young adult presents to the urgent care clinic and reports a stiff neck, a fever for the past 6 hours, and a headache. Which intervention is most important for the nurse to implement first?
- A. Initiate isolation precautions
- B. Administer an antipyretic
- C. Draw blood cultures
- D. Prepare for lumbar puncture
Correct answer: A
Rationale: The correct answer is to initiate isolation precautions. This is the priority action because the patient presents with symptoms that could be indicative of meningitis, an infectious disease that requires isolation to prevent its spread. Administering an antipyretic (Choice B) may help manage the fever but does not address the need for isolation. Drawing blood cultures (Choice C) and preparing for a lumbar puncture (Choice D) are important steps in diagnosing meningitis but should come after initiating isolation precautions to prevent potential transmission of the infection to others.
2. A client with heart failure is prescribed spironolactone. What is the nurse's priority intervention?
- A. Monitor the client's potassium levels closely.
- B. Assess for signs of hyperkalemia.
- C. Instruct the client to increase intake of potassium-rich foods.
- D. Increase the client’s fluid intake to prevent dehydration.
Correct answer: B
Rationale: The correct answer is B: Assess for signs of hyperkalemia. Spironolactone is a potassium-sparing diuretic, which can cause hyperkalemia (high potassium levels). Therefore, the nurse's priority intervention should be to assess the client for signs of hyperkalemia, such as muscle weakness, fatigue, and potentially dangerous cardiac arrhythmias. Monitoring potassium levels closely (choice A) is important but assessing for signs of hyperkalemia takes precedence. Instructing the client to increase intake of potassium-rich foods (choice C) can exacerbate hyperkalemia in this case. Increasing the client’s fluid intake to prevent dehydration (choice D) is not directly related to the potential side effect of spironolactone.
3. A client is receiving meperidine (Demerol) for pain management. Which assessment finding requires immediate action?
- A. Constipation
- B. Drowsiness
- C. Respiratory rate of 10 breaths per minute
- D. Nausea
Correct answer: C
Rationale: A respiratory rate of 10 breaths per minute indicates respiratory depression, a severe side effect of meperidine (Demerol) that necessitates immediate intervention to prevent further complications. Constipation, drowsiness, and nausea are common but less urgent side effects that do not pose an immediate life-threatening risk. Respiratory depression can lead to respiratory arrest and must be addressed promptly to ensure the client's safety and well-being.
4. A client on mechanical ventilation is experiencing high-pressure alarms. What action should the nurse implement first?
- A. Check the client's oxygen saturation.
- B. Assess the client's endotracheal tube for obstruction.
- C. Reposition the client to relieve pressure.
- D. Suction the client's airway.
Correct answer: B
Rationale: The correct answer is to assess the client's endotracheal tube for obstruction. When a client on mechanical ventilation experiences high-pressure alarms, the first action should be to check for any potential obstructions in the airway, which can trigger the alarms. Checking the oxygen saturation (Choice A) is important but not the priority when dealing with high-pressure alarms. Repositioning the client (Choice C) may be necessary later but should not be the initial action. Suctioning the client's airway (Choice D) should only be done after assessing for and addressing any obstructions in the endotracheal tube.
5. Which of these clients, all in the terminal stage of cancer, is least appropriate to suggest the use of patient-controlled analgesia (PCA) with a pump?
- A. A young adult with a history of Down syndrome
- B. A teenager who reads at a 4th-grade level
- C. An elderly client with numerous arthritic nodules on the hands
- D. A preschooler with intermittent alertness
Correct answer: D
Rationale: The correct answer is D, a preschooler with intermittent alertness. This client may not have the cognitive ability to effectively use a PCA pump due to their age and alertness level. They may not understand how to self-administer the analgesia. Choices A, B, and C are more appropriate candidates for PCA as they are likely to have better comprehension and ability to operate the PCA pump compared to a preschooler with intermittent alertness.
