HESI Fundamentals Questions
Question 1 of 5
A client with a diagnosis of coronary artery disease is receiving atorvastatin (Lipitor). Which laboratory test should the nurse monitor to evaluate the effectiveness of this medication?
Correct Answer: C
Rationale: To evaluate the effectiveness of atorvastatin (Lipitor), the nurse should monitor liver function tests (LFTs) (C) because this medication can impact liver function. Complete blood count (CBC) (A), serum potassium level (B), and serum cholesterol level (D) are not directly indicative of the medication's effectiveness in managing coronary artery disease.
Question 2 of 5
The nurse explains to an older adult male the procedure for collecting a 24-hour urine specimen for creatinine clearance. Which action is most important for the nurse to include in their care plan for the shift?
Correct Answer: C
Rationale: To ensure accurate creatinine clearance results, it is crucial to collect all urine within the 24-hour period. The process should begin with discarding the first specimen and then collecting all subsequent urine in the designated 24-hour collection container. This ensures that the sample is complete and accurate for the creatinine clearance calculation.
Question 3 of 5
At 0100 on a male client's second postoperative night, the client states he is unable to sleep and plans to read until feeling sleepy. What action should the nurse implement?
Correct Answer: A
Rationale: The client has expressed a plan to read until feeling sleepy, indicating that he is managing his inability to sleep. In this situation, it is best for the nurse to respect the client's autonomy and leave the room, providing privacy and an opportunity for the client to relax and hopefully fall asleep. Closing the door can also help create a quiet environment conducive to rest.
Question 4 of 5
When assessing a male client, the nurse finds that he is fatigued and 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?
Correct Answer: D
Rationale: The symptoms of fatigue, muscle weakness, leg cramps, and cardiac dysrhythmias are classic manifestations of hypokalemia. Potassium plays a vital role in muscle function and cardiac conduction, so a deficiency can lead to these symptoms. Checking the client's laboratory values for potassium levels will help confirm the presence of hypokalemia.
Question 5 of 5
While changing a client's post-operative dressing, the nurse observes a red and swollen wound with a moderate amount of yellow and green drainage and a foul odor. Given a positive MRSA result, what is the most important action for the nurse to take?
Correct Answer: C
Rationale: Initiating contact precautions is crucial in this situation to prevent the spread of MRSA infection. MRSA is a highly contagious bacterium that can spread through direct contact with an infected wound or by touching contaminated surfaces. By implementing contact precautions, the nurse can help contain the infection and protect other patients, healthcare workers, and visitors from being exposed to MRSA.
