HESI 799 RN Exit Exam Capstone
1. An unresponsive male victim of a diving accident is brought to the emergency department where immediate surgery is required to save his life. No family members are available. What action should the nurse take first?
- A. Ask the friend to sign an informed consent.
- B. Notify the unit manager that a court order is needed.
- C. Continue providing life support until a guardian is found.
- D. Proceed with surgery preparation without consent.
Correct answer: D
Rationale: In emergency situations where immediate surgery is required to save a patient's life and no family members are available, consent can be waived to proceed with necessary interventions. The priority in this scenario is to proceed with surgery preparation without waiting for consent, as any delay could jeopardize the patient's life. Asking the friend to sign informed consent or notifying the unit manager for a court order would cause unnecessary delays, which are not advisable in this critical situation. Continuing life support until a guardian is found is not the most appropriate action when immediate surgical intervention is necessary.
2. When organizing home visits for the day, which older client should the home health nurse plan to visit first?
- A. A woman who takes naproxen (Naprosyn) and reports a recent onset of dark, tarry stools.
- B. A man who receives weekly injections of epoetin (Procrit) for a low serum iron level.
- C. A man with emphysema who smokes and is complaining of white patches in his mouth.
- D. A frail woman with heart failure who reported a 2-pound weight gain in the last week.
Correct answer: A
Rationale: The correct answer is A. Dark, tarry stools may indicate gastrointestinal bleeding, a potentially life-threatening condition that requires immediate attention. Visiting this client first is crucial for prompt assessment and intervention. Choices B, C, and D do not present immediate life-threatening conditions that require urgent attention compared to the potential emergency indicated by dark, tarry stools.
3. A client with hyperthyroidism is admitted to the postoperative unit after a subtotal thyroidectomy. Which of the client's serum laboratory values requires intervention by the nurse?
- A. Blood glucose 90 mg/dL
- B. Sodium 138 mEq/L
- C. Total calcium 5.0 mg/dL
- D. Potassium 4.2 mEq/L
Correct answer: C
Rationale: A total calcium level of 5.0 mg/dL is critically low and indicates possible hypocalcemia, a common complication after thyroid surgery. This condition can lead to tetany and requires immediate intervention. Blood glucose within normal range, sodium, and potassium levels are not indicative of an immediate postoperative complication like hypocalcemia in this case.
4. A client with chronic heart failure is admitted with worsening dyspnea. What is the nurse's priority action?
- A. Administer oxygen at 2 liters per nasal cannula.
- B. Administer a diuretic as prescribed.
- C. Assess the client's lung sounds.
- D. Reposition the client to relieve dyspnea.
Correct answer: A
Rationale: In a client with chronic heart failure experiencing worsening dyspnea, the priority action for the nurse is to administer oxygen at 2 liters per nasal cannula. This helps improve oxygenation and alleviate respiratory distress. Administering a diuretic (Choice B) may be necessary but addressing oxygenation comes first. While assessing lung sounds (Choice C) is important, it is not the immediate priority when the client is in respiratory distress. Repositioning the client (Choice D) may help with comfort but does not address the underlying issue of inadequate oxygenation.
5. In a hospitalized child receiving IV fluids for dehydration, what is the best indicator that the child’s dehydration is improving?
- A. The child’s urine output increases
- B. The child’s skin turgor is normal
- C. The child’s weight increases
- D. The child’s vital signs are stable
Correct answer: A
Rationale: An increase in urine output is a reliable indicator of improving dehydration in a child. It signifies that the kidneys are functioning better, helping to restore fluid balance in the body. Monitoring urine output is crucial in assessing hydration status and response to treatment. Choices B, C, and D are not the best indicators of improving dehydration. Normal skin turgor is helpful but may not change immediately with improving hydration. Weight increase may reflect retained fluids rather than improved hydration status. Stable vital signs are important but may not always indicate improving dehydration.
