HESI RN Exit Exam Questions
Question 1 of 5
The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?
Correct Answer: C
Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.
Question 2 of 5
Before preparing a client for the first surgical case of the day, a part-time scrub nurse asks the circulating nurse if a 3-minute surgical hand scrub is adequate preparation for this client. Which response should the circulating nurse provide?
Correct Answer: D
Rationale: The correct answer is to direct the nurse to continue the surgical hand scrub for a 5-minute duration. Surgical hand scrubs should last for 5 to 10 minutes, ensuring thorough cleaning and disinfection. Choice A is incorrect because the nurse should be guided to complete the scrub properly rather than having someone else do it. Choice B is incorrect as it does not address the duration of the hand scrub. Choice C is incorrect as it suggests a 3-minute hand scrub is sufficient, which is inadequate for proper preparation before surgery.
Question 3 of 5
A client with chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which assessment finding requires immediate intervention?
Correct Answer: C
Rationale: The correct answer is C. The use of accessory muscles indicates increased work of breathing and can signal respiratory failure in a client with COPD. This finding requires immediate intervention to prevent further respiratory compromise. Oxygen saturation of 90% indicates some oxygenation impairment but may not necessitate immediate intervention. A respiratory rate of 24 breaths per minute is slightly elevated but does not indicate immediate respiratory distress. Inspiratory crackles may be present in pneumonia but do not require immediate intervention compared to the increased work of breathing indicated by the use of accessory muscles.
Question 4 of 5
A client with a history of rheumatoid arthritis is prescribed methotrexate. Which laboratory value should the nurse monitor closely?
Correct Answer: C
Rationale: Serum creatinine should be closely monitored in a client receiving methotrexate, as the medication can cause nephrotoxicity. Monitoring serum creatinine levels helps assess kidney function and detect potential nephrotoxic effects of methotrexate. Liver function tests (Choice A) are important to monitor for hepatotoxicity caused by methotrexate. While methotrexate can cause bone marrow suppression, leading to anemia, leukopenia, and thrombocytopenia, monitoring a complete blood count (Choice B) is essential but not the priority in this case. Prothrombin time (Choice D) is not typically affected by methotrexate therapy and is not the primary laboratory value to monitor in this situation.
Question 5 of 5
The nurse is caring for a client who is postoperative following a thyroidectomy. Which assessment finding is most concerning?
Correct Answer: C
Rationale: A positive Chvostek's sign is the most concerning assessment finding as it suggests hypocalcemia, which is a potential complication following thyroidectomy. Hypocalcemia can lead to serious complications such as tetany and laryngospasm. Immediate intervention is required to prevent further complications. Choices A, B, and D are common post-thyroidectomy findings and are expected during the immediate postoperative period. Slight difficulty swallowing may be due to postoperative swelling, a hoarse voice may be temporary due to intubation trauma, and pain at the incision site is normal after surgery.
