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. A postoperative client returns to the nursing unit following a ureter lithotomy via a flank incision. Which potential nursing problem has the highest priority when planning nursing care for this client?
- A. Ineffective airway clearance
- B. Altered nutrition less than body requirements
- C. Fluid volume excess
- D. Activity intolerance
Correct answer: A
Rationale: The correct answer is 'Ineffective airway clearance.' Following a ureter lithotomy via a flank incision, the highest priority nursing problem is ensuring the client's airway remains clear. This is crucial for effective breathing and oxygenation. Altered nutrition, fluid volume excess, and activity intolerance are important to address but are of lower priority compared to maintaining a clear airway postoperatively.
3. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen at 2 liters per minute via nasal cannula. The client reports difficulty breathing. What action should the nurse take first?
- A. Increase the oxygen flow rate
- B. Instruct the client to breathe deeply and cough
- C. Check the client's oxygen saturation level
- D. Place the client in a high-Fowler's position
Correct answer: C
Rationale: The correct action for the nurse to take first when a client with COPD reports difficulty breathing while receiving oxygen is to check the client's oxygen saturation level. This helps in determining the adequacy of oxygenation and identifying the cause of the breathing difficulty. Increasing the oxygen flow rate (Choice A) may not be appropriate without knowing the current oxygen saturation level. Instructing the client to breathe deeply and cough (Choice B) may not address the immediate need for oxygen assessment. Placing the client in a high-Fowler's position (Choice D) can help with breathing but should come after ensuring proper oxygenation.
4. A client is taught how to collect a 24-hour urine specimen. Which statement indicates understanding of the procedure?
- A. I should keep the urine specimen refrigerated.
- B. I need to start the collection in the morning after my first void.
- C. I will collect the urine for 24 hours and keep it on ice.
- D. I will start collecting the urine after discarding my first morning specimen.
Correct answer: D
Rationale: The correct way to collect a 24-hour urine specimen is to discard the first morning void and then start the collection. Choice A is incorrect because refrigeration is not typically necessary for a 24-hour urine specimen. Choice B is incorrect as the client needs to discard the first void. Choice C is incorrect; while collecting urine for 24 hours is correct, keeping it on ice is not standard procedure.
5. A client receiving amlodipine (Norvasc), a calcium channel blocker, develops 1+ pitting edema around the ankles. It is most important for the nurse to obtain what additional client data?
- A. Bladder distention
- B. Serum albumin level
- C. Abdominal girth
- D. Breath sounds
Correct answer: D
Rationale: The correct answer is 'D. Breath sounds.' When a client receiving amlodipine develops edema, it is crucial to assess for potential heart failure, a side effect of the medication. Checking breath sounds helps in identifying any signs of pulmonary edema, a severe complication of heart failure. Choices A, B, and C are less relevant in this context. Bladder distention could be associated with urinary issues, serum albumin level with malnutrition or liver disease, and abdominal girth with gastrointestinal problems, none of which directly relate to the potential heart failure induced by amlodipine.
