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. The nurse reviews the diagnostic tests prescribed for a client with a positive skin test. Which subjective findings reported by the client support the diagnosis of tuberculosis?
- A. Mucopurulent cough and night sweats
- B. Fatigue and headache
- C. Persistent cough and weight gain
- D. Weight loss and fever
Correct answer: A
Rationale: A mucopurulent cough and night sweats are hallmark signs of active tuberculosis. These symptoms are key indicators of TB as the combination of a productive cough with night sweats is highly suggestive of the disease. Fatigue and headache (choice B) are nonspecific symptoms that can occur in many conditions and are not specific to TB. Persistent cough and weight gain (choice C) are not typical findings in tuberculosis. Weight loss and fever (choice D) can be present in TB, but the specific combination of mucopurulent cough and night sweats is more specific to the diagnosis.
3. The nurse is administering a new medication to a client. What is the priority action before administering the drug?
- A. Verify the client's allergies
- B. Check the client's blood pressure
- C. Assess the client's pain level
- D. Provide client education on the medication
Correct answer: A
Rationale: Verifying the client's allergies is the priority action before administering any medication. It is crucial to identify any known allergies to prevent potential allergic reactions, which can be severe and life-threatening. Checking the client's blood pressure, assessing pain levels, and providing education on the medication are important aspects of client care but verifying allergies is essential for ensuring the safety of the client.
4. A 5-week-old infant with hypertrophic pyloric stenosis has developed projectile vomiting over the last two weeks. Which intervention should the nurse plan to implement?
- A. Instruct the mother to give sugar water only.
- B. Offer the infant oral rehydration every 2 hours.
- C. Provide Pedialyte feedings via nasogastric tube.
- D. Maintain intravenous fluid therapy.
Correct answer: D
Rationale: The correct intervention for a 5-week-old infant with hypertrophic pyloric stenosis presenting with projectile vomiting is to maintain intravenous fluid therapy. This is essential to maintain hydration before surgery. Instructing the mother to give sugar water only (Choice A) is inadequate and does not address the need for proper hydration. Offering oral rehydration every 2 hours (Choice B) may not be effective in cases of severe vomiting and could lead to further fluid loss. Providing Pedialyte feedings via nasogastric tube (Choice C) is an option, but in severe cases, intravenous fluid therapy is more effective in ensuring hydration and electrolyte balance.
5. A client is newly prescribed lithium for bipolar disorder. Which finding is most important to report to the healthcare provider?
- A. A serum lithium level of 1.2 mEq/L.
- B. Fine hand tremors noted after starting the medication.
- C. A blood pressure of 110/60 mmHg.
- D. A serum sodium level of 140 mEq/L.
Correct answer: B
Rationale: The correct answer is B. Fine hand tremors noted after starting lithium are an early sign of lithium toxicity. It is crucial to report this finding to the healthcare provider promptly. Adjusting the dose or monitoring serum levels more closely may be necessary to prevent further toxicity. Choice A, a serum lithium level of 1.2 mEq/L, is within the therapeutic range (0.6-1.2 mEq/L) for treating bipolar disorder. Choice C, a blood pressure of 110/60 mmHg, and Choice D, a serum sodium level of 140 mEq/L, are within normal limits and not directly related to lithium therapy or toxicity.
