HESI Fundamentals 2023 Test Bank Questions

Question 1 of 5

The nurse is caring for a client with a central venous catheter. What is the most important action for the nurse to take to prevent infection?

Correct Answer: D

Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. Changing the catheter dressing every 72 hours, while important for overall catheter care, does not directly address infection prevention. Flushing the catheter with heparin solution daily is essential for maintaining patency but does not primarily prevent infections. Ensuring the catheter is clamped when not in use is important for preventing air embolism but is not the most critical action to prevent infection. The most effective way to prevent infections is by strictly adhering to sterile techniques during catheter handling, which minimizes the risk of introducing pathogens into the catheter site.

Question 2 of 5

A client with pneumonia is receiving antibiotic therapy. Which finding indicates that the treatment is effective?

Correct Answer: C

Rationale: The correct answer is C: Increased breath sounds. When a client with pneumonia is receiving antibiotic therapy, increased breath sounds indicate that the lungs are clearing and the pneumonia is resolving. This improvement in breath sounds suggests that the antibiotics are effectively treating the infection. Choices A, B, and D are incorrect because a decreased white blood cell count, decreased respiratory rate, and increased heart rate are not specific indicators of the effectiveness of antibiotic therapy in treating pneumonia. While these parameters may change in response to treatment, they do not directly reflect the resolution of the pneumonia infection.

Question 3 of 5

A client with chronic kidney disease is being assessed. Which of the following laboratory values would be most concerning?

Correct Answer: B

Rationale: In a client with chronic kidney disease, elevated serum potassium levels (hyperkalemia) are the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias. Monitoring and managing serum potassium levels are crucial in patients with kidney disease to prevent severe complications. While elevated creatinine (Choice A) and BUN (Choice C) are indicative of impaired kidney function, hyperkalemia poses a more immediate threat to the client's health. Hemoglobin levels (Choice D) can be affected by chronic kidney disease but are not as acutely dangerous as severe hyperkalemia.

Question 4 of 5

A nurse is collecting a blood pressure reading from a client who is sitting in a chair. The nurse determines that the client's BP is 158/96 mmHg. Which of the following actions should the nurse take?

Correct Answer: C

Rationale: When a nurse obtains a blood pressure reading that is elevated, the appropriate action is to recheck the client's BP and measure the other arm for comparison. This step helps ensure accuracy by ruling out errors like improper cuff size, positioning, or equipment malfunction. Repositioning the client supine is not necessary unless the client shows signs of distress or symptoms. Ensuring the appropriate cuff width is important for accurate readings but does not address the immediate need to confirm the current BP. Requesting another nurse to check the BP in 30 minutes delays immediate action and does not address the need for verification and comparison of the current reading.

Question 5 of 5

During an admission history, a client tells a nurse that she is under a lot of stress. Which of the following physiological responses should the nurse expect to increase as a result of stress?

Correct Answer: A

Rationale: The correct answer is A. Stress typically increases blood glucose levels due to the release of stress hormones like cortisol and adrenaline. Elevated blood glucose helps provide energy for the body to cope with the stressful situation. Choice B is incorrect because intestinal peristalsis, the movement of the intestines, is more likely to decrease under stress due to the 'fight or flight' response. Choice C is incorrect as peripheral blood vessels' diameter may vary in response to stress, with both constriction and dilation possible. Choice D is incorrect as urine output may increase or decrease depending on individual differences and the specific stress response, but it is not a typical or direct physiological response to stress.
