HESI 799 RN Exit Exam Capstone
1. A client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?
- A. Administer IV calcium gluconate.
- B. Administer sodium polystyrene sulfonate (Kayexalate).
- C. Administer insulin with dextrose.
- D. Restrict potassium intake in the client's diet.
Correct answer: A
Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.
2. A client with cirrhosis is experiencing ascites and peripheral edema. What is the nurse's priority intervention?
- A. Administer furosemide as prescribed.
- B. Administer albumin to increase oncotic pressure.
- C. Elevate the client's legs to reduce swelling.
- D. Administer a sodium-restricted diet.
Correct answer: A
Rationale: The correct answer is A: Administer furosemide as prescribed. Administering furosemide, a loop diuretic, is the priority intervention in a client with cirrhosis experiencing ascites and peripheral edema. Furosemide helps promote diuresis and reduce fluid buildup in the body. Choice B, administering albumin to increase oncotic pressure, may be beneficial in some cases but is not the priority intervention for immediate fluid removal. Elevating the client's legs (Choice C) and administering a sodium-restricted diet (Choice D) are important aspects of managing edema and ascites but are not the priority interventions in this situation.
3. A client is admitted to the hospital with a diagnosis of pneumonia. The client is prescribed intravenous antibiotics and oxygen therapy. Which assessment finding indicates that the client's condition is improving?
- A. Increased white blood cell count
- B. Crackles heard on lung auscultation
- C. Productive cough with green sputum
- D. Decreased respiratory rate from 24 to 18 breaths per minute
Correct answer: D
Rationale: A decrease in respiratory rate indicates that the client's breathing is becoming more stable, which suggests an improvement in their condition. Respiratory rate is a critical indicator of respiratory status and oxygenation. Increased white blood cell count (choice A) suggests ongoing infection, crackles on lung auscultation (choice B) indicate fluid in the lungs, and productive cough with green sputum (choice C) may indicate persistent infection or airway inflammation, which do not necessarily reflect improvement in pneumonia.
4. A client is scheduled for a colonoscopy and has been prescribed a bowel preparation. What is the most important instruction for the nurse to provide?
- A. Eat a low-fiber diet the day before the procedure
- B. Drink clear liquids 24 hours before the procedure
- C. Take the entire bowel preparation as directed
- D. Avoid all solid foods 12 hours before the procedure
Correct answer: C
Rationale: The most important instruction for the nurse to provide to a client scheduled for a colonoscopy and prescribed a bowel preparation is to take the entire bowel preparation as directed. Completing the entire bowel preparation as prescribed is crucial to ensure the colon is properly cleansed for the colonoscopy. Incomplete bowel prep can interfere with the visualization of the colon, leading to inaccurate results. Choices A, B, and D are important but not as crucial as ensuring the complete intake of the bowel preparation for an effective procedure.
5. The healthcare provider prescribes an IV infusion of isoproterenol in D5W at 300 mcg/hour. How many ml/hour should the nurse set the pump to?
- A. 100 ml/hour
- B. 75 ml/hour
- C. 60 ml/hour
- D. 125 ml/hour
Correct answer: B
Rationale: To calculate the correct infusion rate, convert 300 mcg/hour to mg/hour (300 mcg = 0.3 mg). Since the IV solution is 1 mg in 250 ml, the rate is calculated as 0.3 mg/hour = 75 ml/hour. Therefore, the nurse should set the pump to 75 ml/hour. Choice A (100 ml/hour) is incorrect as it does not reflect the accurate calculation. Choice C (60 ml/hour) is incorrect as it is lower than the correct rate. Choice D (125 ml/hour) is incorrect as it is higher than the correct rate.
