HESI CAT Exam 2022 Questions

Question 1 of 5

A client is receiving lidocaine IV at 3 mg/minute. The pharmacy dispenses a 500 ml IV solution of normal saline (NS) with 2 grams of lidocaine. The nurse should regulate the infusion pump to deliver how many ml/hour?

Correct Answer: D

Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg).
Then, use the formula: (
Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour.
Therefore, the correct answer is D.

Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.

Question 2 of 5

The nursing staff on a medical unit includes a registered nurse (RN), practical nurse (PN), and an unlicensed assistive personnel (UAP). Which task should the charge nurse assign to the RN?

Correct Answer: C

Rationale: The correct answer is C because supervising a newly hired graduate nurse during an admission assessment is a task that falls within the registered nurse's scope of practice. Registered nurses are responsible for overseeing and delegating tasks, especially to new staff, to ensure proper assessment and care delivery.

Choices A, B, and D involve tasks that can be appropriately assigned to practical nurses or unlicensed assistive personnel as they are within their scope of practice. Transporting a client, administering oral analgesics, and completing focused assessments do not require the advanced knowledge and skills of a registered nurse.

Question 3 of 5

A female client has been taking a high dose of prednisone, a corticosteroid, for several months. After stopping the medication abruptly, the client reports feeling very tired. Which nursing intervention is most important for the nurse to implement?

Correct Answer: A

Rationale: Discontinuing prednisone abruptly can lead to adrenal insufficiency, which may result in symptoms such as fatigue. Monitoring vital signs is crucial in this situation to assess for potential complications like hypotension, which can be a sign of adrenal insufficiency. Auscultating breath sounds (choice
B) is important but not the priority when considering the risk of adrenal insufficiency. Palpating the abdomen (choice
C) and observing the skin for bruising (choice
D) are not directly related to the potential complications of abruptly stopping prednisone.

Question 4 of 5

The nurse administers an oral antiviral to a client with shingles. Which finding is most important for the nurse to report to the healthcare provider?

Correct Answer: C

Rationale: The correct answer is C: Elevated liver function tests. When administering antivirals, especially orally, monitoring liver function tests is crucial as it may indicate liver toxicity. This finding should be reported promptly to the healthcare provider to prevent further complications.
Choice A, decreased white blood cell count, may be expected with certain antivirals but is not the most critical finding in this scenario. Pruritus and muscle aches (choice
B) are common side effects of antivirals and do not require immediate reporting. Vomiting and diarrhea (choice
D) are also common side effects that may not be as concerning as elevated liver function tests.

Question 5 of 5

An adult male is admitted to the intensive care unit because he experienced a sudden onset of sharp chest pain and shortness of breath earlier today. Following an emergent pulmonary angiogram, the client is diagnosed with a pulmonary embolism. Which intervention is most important for the nurse to include in this client's plan of care?

Correct Answer: A

Rationale: In a patient diagnosed with a pulmonary embolism, the most critical intervention is to monitor for signs of increased bleeding. Pulmonary embolism treatment often involves anticoagulation therapy, which increases the risk of bleeding. Monitoring for signs of bleeding such as bruising, petechiae, hematuria, or gastrointestinal bleeding is essential to prevent complications. Instructing on the use of incentive spirometry can be beneficial for preventing pulmonary complications but is not as urgent as monitoring for bleeding. Observing for confusion and restlessness may indicate hypoxia but is not the most crucial intervention in this scenario. Administering intravenous opioids for severe pain might be necessary but is not the priority compared to monitoring for bleeding, which is directly related to the treatment for pulmonary embolism.
