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 in atrial fibrillation. The atrial heart rate is 250, and the ventricular rate is controlled at 75. Which of the following findings is cause for the most concern?
- A. Diminished bowel sounds
- B. Loss of appetite
- C. A cold, pale lower leg
- D. Tachypnea
Correct answer: C
Rationale: A cold, pale lower leg is cause for the most concern as it could indicate compromised blood circulation, potentially leading to serious complications like ischemia or thrombosis. Diminished bowel sounds, loss of appetite, and tachypnea are not directly related to the client's condition in atrial fibrillation and the heart rate discrepancy.
3. A teenager presents to the emergency department with palpitations after vaping at a party. The client is anxious, fearful, and hyperventilating. Which acid-base imbalance does the nurse anticipate the client developing?
- A. Metabolic alkalosis
- B. Respiratory alkalosis
- C. Respiratory acidosis
- D. Metabolic acidosis
Correct answer: B
Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation from anxiety or fear causes an excessive loss of CO2, leading to respiratory alkalosis. This shift in pH results from the rapid, shallow breathing that reduces the level of carbon dioxide in the blood. Respiratory acidosis would occur in cases of poor ventilation or CO2 retention, while metabolic acidosis/alkalosis relates to disturbances in bicarbonate, not breathing patterns. Therefore, in this case, the client's hyperventilation due to anxiety would likely result in respiratory alkalosis, making option B the correct choice.
4. A client with heart failure is experiencing shortness of breath and swelling in the legs. What is the nurse's priority intervention?
- A. Administer prescribed diuretics
- B. Place the client in a supine position
- C. Restrict fluid intake immediately
- D. Increase the client's sodium intake
Correct answer: A
Rationale: The correct answer is A: Administer prescribed diuretics. Diuretics are prescribed to reduce fluid overload in clients with heart failure. By promoting urine output, diuretics help alleviate symptoms like shortness of breath and swelling. While placing the client in a supine position can help with breathing and fluid redistribution, administering diuretics takes precedence as it directly addresses fluid overload. Restricting fluid intake immediately may be necessary in some cases, but the immediate priority is to administer diuretics. Increasing the client's sodium intake would worsen fluid retention and is contraindicated in heart failure.
5. Which intervention should be prioritized by the nurse when assessing tissue perfusion post-above knee amputation (AKA)?
- A. Evaluate the closest proximal pulse.
- B. Observe color and amount of wound drainage.
- C. Observe for swelling around the stump.
- D. Assess the skin elasticity of the stump.
Correct answer: A
Rationale: The correct answer is to evaluate the closest proximal pulse when assessing tissue perfusion post-above knee amputation (AKA). Checking the closest proximal pulse provides the best indication of tissue perfusion in the extremities after an AKA procedure. Observing the color and amount of wound drainage (Choice B) is important for wound care but does not directly assess tissue perfusion. Observing for swelling around the stump (Choice C) may indicate inflammation or fluid accumulation but is not the most direct way to assess tissue perfusion. Assessing the skin elasticity of the stump (Choice D) is more related to skin integrity and wound healing rather than tissue perfusion.
