RN HESI Exit Exam Capstone
1. A client who has been prescribed multiple antihypertensive medications experiences syncope and has a blood pressure of 70/40. What is the rationale for the nurse to hold the next scheduled antihypertensive dose?
- A. Increased urinary clearance of the medications has produced diuresis, lowering the blood pressure.
- B. The antagonistic interaction of the medications has reduced their effectiveness.
- C. The synergistic effect of the medications has resulted in drug toxicity, causing hypotension.
- D. The additive effect of the medications has lowered the blood pressure too much.
Correct answer: D
Rationale: The additive effect of multiple antihypertensive medications can cause hypotension, leading to dangerously low blood pressure. In this scenario, the client experiencing syncope with a blood pressure of 70/40 indicates severe hypotension, likely due to the combined action of the antihypertensive medications. Holding the next scheduled dose is essential to prevent further lowering of blood pressure and potential complications. Choices A, B, and C provide inaccurate explanations and do not align with the client's presentation and the need to manage hypotension caused by the additive effect of the medications.
2. The nurse is caring for a client with a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Which intervention is most important for the nurse to implement?
- A. Encourage oral hydration
- B. Monitor for signs of dehydration
- C. Restrict fluid intake
- D. Administer IV fluids as prescribed
Correct answer: C
Rationale: In SIADH, there is excessive ADH secretion leading to water retention and dilutional hyponatremia. The most crucial intervention is to restrict fluid intake to prevent further fluid overload and worsening of hyponatremia. Encouraging oral hydration (choice A) would exacerbate the condition by adding more fluids. Monitoring for signs of dehydration (choice B) is not appropriate as the client is at risk of fluid overload. Administering IV fluids (choice D) would worsen the hyponatremia and should be avoided.
3. A client with hyperthyroidism is admitted for total thyroidectomy. What is the nurse's priority post-operative intervention?
- A. Monitor the client's calcium levels for hypocalcemia.
- B. Monitor for signs of respiratory distress.
- C. Administer oral calcium supplements.
- D. Elevate the head of the bed to 45 degrees.
Correct answer: A
Rationale: The correct answer is to monitor the client's calcium levels for hypocalcemia. After a total thyroidectomy, there is a risk of accidental removal or damage to the parathyroid glands, leading to hypocalcemia. This complication can manifest within the first 24-48 hours post-op. Monitoring calcium levels is crucial to prevent serious complications such as tetany or seizures. While monitoring for respiratory distress is important, it is not the priority in this case. Administering oral calcium supplements should only be done based on the healthcare provider's prescription and after assessing the client's calcium levels. Elevating the head of the bed to 45 degrees is beneficial for respiratory function but is not the priority intervention for a client at risk for hypocalcemia post-thyroidectomy.
4. A client with hypertension is prescribed a beta-blocker. What teaching should the nurse provide about this medication?
- A. Instruct the client to avoid high-potassium foods.
- B. Monitor the client’s heart rate and report any bradycardia.
- C. Advise the client to rise slowly from a sitting or lying position.
- D. Instruct the client to avoid sudden position changes.
Correct answer: C
Rationale: The correct answer is to advise the client to rise slowly from a sitting or lying position. Beta-blockers can cause bradycardia and hypotension, so clients should be advised to rise slowly to prevent dizziness and falls. Monitoring the client's heart rate and blood pressure regularly is essential. Instructing the client to avoid high-potassium foods (Choice A) is not directly related to beta-blockers. While monitoring the client's heart rate (Choice B) is important, advising the client to rise slowly (Choice C) is more directly related to potential side effects of beta-blockers. Instructing the client to avoid sudden position changes (Choice D) is not as specific or essential as advising them to rise slowly to prevent adverse effects.
5. The nurse is caring for a client who requires a mechanical ventilator for breathing. The high-pressure alarm goes off on the ventilator. What is the first action the nurse should perform?
- A. Disconnect the client from the ventilator and use a manual resuscitation bag
- B. Perform a quick assessment of the client's condition
- C. Call the respiratory therapist for help
- D. Press the alarm reset button on the ventilator
Correct answer: B
Rationale: The correct answer is to perform a quick assessment of the client's condition when the high-pressure alarm goes off on the ventilator. This assessment is crucial to determine the cause of the alarm and the client's current status. Option A is incorrect because disconnecting the client from the ventilator without assessing the situation can be harmful. Option C is incorrect as the nurse should first assess the client before seeking additional help. Option D is incorrect because resetting the alarm without understanding the underlying issue may lead to potential risks to the client.
