HESI RN
HESI RN Exit Exam Capstone
1. An older client is admitted to the intensive care unit unconscious after several days of vomiting and diarrhea. The nurse inserts a urinary catheter and observes dark amber urine output. Which intervention should the nurse implement first?
- A. Begin dopamine infusion at 2 mcg/kg/minute.
- B. Begin potassium chloride 10 mEq over 1 hour.
- C. Give a bolus of 0.9% sodium chloride 1000 mL over 30 minutes.
- D. Administer promethazine 25 mg IV push.
Correct answer: C
Rationale: In this scenario, the priority intervention is to give a bolus of 0.9% sodium chloride 1000 mL over 30 minutes. The client's dark amber urine output indicates dehydration and hypovolemia, requiring rapid fluid resuscitation. Dopamine infusion, potassium chloride, and promethazine are not the initial interventions needed for a client with hypovolemic symptoms.
2. Twenty-four hours after admission to the newborn nursery, a full-term male infant develops localized edema on the right side of his head. The LPN/LVN knows that, in the newborn, an accumulation of blood between the periosteum and skull which does not cross the suture line is a newborn variation known as
- A. a cephalhematoma, caused by birth trauma and may last up to 8 weeks.
- B. a subarachnoid hematoma, which requires immediate drainage to prevent further complications.
- C. molding, caused by pressure during labor and will disappear within 2 to 3 days.
- D. a subdural hematoma, which can result in lifelong damage.
Correct answer: A
Rationale: Cephalhematoma is the accumulation of blood between the periosteum and skull, often due to birth trauma, and typically resolves within weeks. It is a common finding in newborns and is not usually a cause for concern as it gradually resolves without specific treatment. Subarachnoid hematoma and subdural hematoma are different conditions that present with distinct characteristics and require different management strategies. Therefore, the correct answer is A. Subarachnoid hematoma is typically found in the subarachnoid space and requires immediate intervention, not just observation like cephalhematoma. Molding refers to the shaping of the fetal head during passage through the birth canal and is a temporary change, not a collection of blood like in cephalhematoma. Subdural hematoma is located beneath the dura mater and is associated with significant complications, unlike the self-limiting nature of cephalhematoma.
3. A client is admitted to the ER with DKA. In the acute phase, the priority nursing action is to prepare to:
- A. Administer regular insulin intravenously
- B. Administer 5% dextrose intravenously
- C. Correct the acidosis
- D. Apply an electrocardiogram monitor
Correct answer: A
Rationale: Administering regular insulin intravenously is the priority nursing action in the acute phase of DKA. Insulin helps to lower blood glucose levels by promoting cellular uptake of glucose and inhibiting ketone production. Administering dextrose would be counterproductive as it can worsen hyperglycemia. Correcting acidosis is important but usually follows insulin administration. Applying an electrocardiogram monitor is not the priority action in the acute management of DKA.
4. A nurse manager works hard to keep employee morale high with the thought that this will lead to effective employees doing the best work they can. Which of the following theories does this best describe?
- A. Theory X
- B. Theory Y
- C. Servant leadership
- D. Scientific management
Correct answer: B
Rationale: Theory Y, as proposed by Douglas McGregor, emphasizes that employees are intrinsically motivated and seek responsibility. It suggests that high morale leads to high productivity, aligning with the nurse manager's actions. Theory X, on the other hand, assumes employees are inherently lazy and need to be closely monitored and controlled. Servant leadership focuses on serving others first and prioritizing their needs, which is not directly related to the scenario described. Scientific management, developed by Frederick Taylor, emphasizes efficiency and standardization through systematic study and organizational control, which is not the primary focus of the nurse manager's approach to boosting employee morale.
5. The nurse is caring for five clients on the medical-surgical unit. Which clients would the nurse consider to be at risk for post-renal acute kidney injury (AKI)? (Select all that apply.)
- A. Man with prostate cancer
- B. Woman with blood clots in the urinary tract
- C. Client with ureterolithiasis
- D. All of the above
Correct answer: D
Rationale: Post-renal acute kidney injury (AKI) occurs due to urine flow obstruction, which can result from conditions such as prostate cancer, blood clots in the urinary tract, and ureterolithiasis (kidney stones). Severe burns would lead to pre-renal AKI by reducing blood flow to the kidneys. Lupus would cause intrarenal AKI by affecting the kidney tissue directly. Therefore, options A, B, and C are correct choices for clients at risk for post-renal AKI, making option D the correct answer.
