HESI RN
HESI RN CAT Exit Exam
1. The nurse assesses a client who is receiving an infusion of 5% dextrose in water with 20 mEq of potassium chloride. The client has oliguria and a serum potassium level of 6.5 mEq/L. What action should the nurse implement first?
- A. Notify the healthcare provider of the laboratory results
- B. Decrease the rate of the IV infusion
- C. Stop the infusion
- D. Administer sodium polystyrene sulfonate (Kayexalate)
Correct answer: C
Rationale: The correct action for the nurse to implement first is to stop the infusion. Stopping the infusion is crucial to prevent further potassium from being administered, which can exacerbate the client's hyperkalemia. Notifying the healthcare provider of the laboratory results (Choice A) can be done after taking immediate action to stop the infusion. Decreasing the rate of the IV infusion (Choice B) may not be sufficient to address the high potassium level quickly. Administering sodium polystyrene sulfonate (Kayexalate) (Choice D) is not the initial action for managing hyperkalemia; stopping the potassium infusion takes precedence.
2. The nurse is caring for a client with a chest tube in place following a pneumothorax. Which finding requires immediate intervention?
- A. Oxygen saturation of 95%
- B. Crepitus around the insertion site
- C. Subcutaneous emphysema
- D. Drainage of 50 ml per hour
Correct answer: C
Rationale: Subcutaneous emphysema requires immediate intervention in a client with a chest tube following a pneumothorax as it can indicate a pneumothorax recurrence or air leak. Oxygen saturation of 95% is within the normal range and does not require immediate intervention. Crepitus around the insertion site can be expected post-procedure and may not necessitate immediate action. Drainage of 50 ml per hour is a normal finding and does not raise immediate concerns.
3. The healthcare professional is providing education on healthy eating habits to a group of adolescents. Which strategy is most likely to be effective?
- A. lecturing about the dangers of unhealthy eating
- B. distributing pamphlets on healthy food choices
- C. involving the adolescents in meal planning and preparation
- D. showing a documentary on the benefits of a healthy diet
Correct answer: C
Rationale: Involving adolescents in meal planning and preparation is a more effective strategy as it actively engages them in the learning process. This approach allows adolescents to have hands-on experience, make informed choices, and develop a sense of ownership over their dietary decisions. Lecturing about dangers or showing documentaries may not be as engaging or interactive, making it less likely for adolescents to retain and apply the information provided. Distributing pamphlets can be informative but lacks the interactive and experiential aspect that involving them in meal planning and preparation offers.
4. In assessing a client with type 1 diabetes mellitus, the nurse notes that the client's respirations have changed from 16 breaths/min with a normal depth to 32 breaths/min and deep, and the client becomes lethargic. Which assessment data should the nurse obtain next?
- A. Pulse oximetry
- B. Blood glucose
- C. Arterial blood gases
- D. Serum electrolytes
Correct answer: B
Rationale: Deep, rapid respirations (Kussmaul respirations) and lethargy are signs of diabetic ketoacidosis (DKA), which occurs in uncontrolled type 1 diabetes. Checking the blood glucose is the priority to confirm hyperglycemia and guide immediate treatment. Pulse oximetry is not the priority in this situation as the issue is related to altered glucose levels, not oxygenation. Arterial blood gases and serum electrolytes may be important later in the management of DKA but are not the initial priority compared to confirming and addressing the hyperglycemia.
5. A client is prescribed atorvastatin (Lipitor) for hyperlipidemia. Which instruction should the nurse include in the teaching plan?
- A. Take the medication in the morning.
- B. Avoid consuming grapefruit juice.
- C. Increase intake of dairy products.
- D. Take the medication with food.
Correct answer: B
Rationale: The correct instruction for the nurse to include in the teaching plan is to advise the client to avoid consuming grapefruit juice. Grapefruit juice can increase the risk of atorvastatin (Lipitor) toxicity by inhibiting its metabolism. Atorvastatin is typically taken in the evening because cholesterol synthesis occurs at night. Increasing dairy intake is not specifically recommended for atorvastatin use, and the medication can be taken with or without food.
