HESI RN Exit Exam 2023 Capstone
1. While auscultating heart sounds, the nurse hears a swishing sound. How should this sound be documented?
- A. Heart murmur.
- B. Murmur.
- C. S3 sound.
- D. S4 sound.
Correct answer: B
Rationale: The correct answer is B: 'Murmur.' A murmur is a swishing sound heard during auscultation, typically caused by turbulent blood flow through the heart or valves. Choices C and D, 'S3 sound' and 'S4 sound,' refer to specific heart sounds associated with different cardiac conditions, not the general description of a swishing sound. Choice A, 'Heart murmur,' is redundant as 'murmur' alone is sufficient to describe the swishing sound heard.
2. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarction of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?
- A. The aortic semilunar valve obstructs blood flow into the systemic circulation
- B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
- C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
- D. An opening in the atrial septum causes a murmur due to a turbulent left-to-right shunt
Correct answer: B
Rationale: The correct answer is B. Coarctation of the aorta causes narrowing of the aorta, reducing blood flow to the lower extremities. This narrowing results in higher blood pressure in the arms compared to the lower extremities, along with stronger brachial pulses and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanism of coarctation of the aorta, which specifically leads to reduced blood flow to the lower extremities.
3. A female client with a history of pheochromocytoma is admitted to the hospital in an acute hypertensive crisis. To reverse the hypertensive crisis caused by pheochromocytoma, nurse Lyka expects to administer:
- A. Phentolamine (Regitine)
- B. Methyldopa (Aldomet)
- C. Mannitol (Osmitrol)
- D. Felodipine (Plendil)
Correct answer: A
Rationale: In a hypertensive crisis due to pheochromocytoma, the appropriate medication to administer is Phentolamine (Regitine), an alpha-adrenergic blocker. Phentolamine acts quickly to block the effects of excess catecholamines that are released in pheochromocytoma, helping to rapidly lower blood pressure. Methyldopa (Aldomet) is an alpha-2 adrenergic agonist used for chronic hypertension, not for acute crises like pheochromocytoma. Mannitol (Osmitrol) is an osmotic diuretic used to reduce intracranial pressure and treat cerebral edema, not indicated for hypertensive crises. Felodipine (Plendil) is a calcium channel blocker used for chronic management of hypertension, not for acute hypertensive crises like those seen in pheochromocytoma.
4. The nurse is caring for a client with deep vein thrombosis (DVT) who is receiving anticoagulant therapy. Which intervention should the nurse implement to prevent complications?
- A. Elevate the affected leg
- B. Encourage early ambulation
- C. Perform frequent range-of-motion exercises
- D. Apply ice packs to the affected leg
Correct answer: A
Rationale: Elevating the affected leg is crucial in managing deep vein thrombosis (DVT) as it helps to reduce swelling and improve venous return. This intervention is essential for preventing complications such as pulmonary embolism. Encouraging early ambulation is generally beneficial for preventing DVT but is secondary to leg elevation. Performing range-of-motion exercises can be helpful for maintaining joint mobility but is not the priority intervention in this case. Applying ice packs to the affected leg is not recommended in DVT management as it can cause vasoconstriction and potentially worsen the condition.
5. A nurse assesses a client who is recovering from a nephrostomy. Which assessment findings should alert the nurse to urgently contact the healthcare provider? (Select all that apply.)
- A. Foul-smelling drainage
- B. Bloody drainage at site
- C. A & B
- D. All of the above
Correct answer: C
Rationale: After a nephrostomy, the nurse should assess the client for complications and urgently notify the provider if there is foul-smelling drainage, bloody drainage at the site, or both. Foul-smelling drainage can indicate infection, while bloody drainage may suggest bleeding. Clear drainage is generally normal after a nephrostomy. A headache would not typically be directly related to nephrostomy complications. Therefore, options A and B are correct choices for urgent notification, making option C the correct answer.
