1. The nurse is caring for a client who is postoperative following a thyroidectomy. Which laboratory value should be monitored closely?
- A. Serum calcium of 8.5 mg/dL
- B. Serum sodium of 136 mEq/L
- C. Serum potassium of 3.0 mEq/L
- D. Serum chloride of 102 mEq/L
Correct answer: C
Rationale: A serum potassium level of 3.0 mEq/L should be monitored closely in a client who is postoperative following a thyroidectomy to detect any electrolyte imbalances. After a thyroidectomy, there is a risk of hypokalemia due to the effects of anesthesia, stress response, and the surgical procedure itself. Monitoring serum potassium levels is crucial as hypokalemia can lead to cardiac arrhythmias and muscle weakness. Serum calcium, sodium, and chloride levels are important but not the primary focus following a thyroidectomy, making them incorrect choices.
2. During the infusion of a second unit of packed red blood cells, the client's temperature increases from 99 to 101.6 F. Which intervention should the nurse implement?
- A. Stop the transfusion and start a saline infusion.
- B. Administer antipyretics and continue the transfusion.
- C. Monitor the client’s vital signs every 15 minutes.
- D. Notify the healthcare provider and continue the transfusion.
Correct answer: A
Rationale: An increase in temperature during a transfusion may indicate a transfusion reaction, which can be serious. Stopping the transfusion and starting a saline infusion is the priority action to prevent further complications and address the potential adverse reaction. Administering antipyretics (choice B) may mask the symptoms of a transfusion reaction, delaying appropriate treatment. While monitoring vital signs (choice C) is important, stopping the transfusion takes precedence to prevent harm. Notifying the healthcare provider (choice D) is essential but should not delay the immediate intervention of stopping the transfusion and starting a saline infusion.
3. A client with chronic kidney disease (CKD) is scheduled for hemodialysis. Which laboratory value should the nurse report to the healthcare provider before the procedure?
- A. Serum potassium of 5.5 mEq/L
- B. Hemoglobin of 10 g/dl
- C. Potassium of 6.0 mEq/L
- D. Blood glucose of 200 mg/dl
Correct answer: C
Rationale: The correct answer is C: Potassium of 6.0 mEq/L. A potassium level of 6.0 mEq/L is dangerously high in a client with CKD, and it should be reported before hemodialysis to prevent cardiac complications. High potassium levels can lead to life-threatening arrhythmias. Choices A, B, and D are not the most critical values to report before hemodialysis. While a serum potassium level of 5.5 mEq/L is slightly elevated, it is not as urgent as a level of 6.0 mEq/L in this context. Hemoglobin of 10 g/dl and blood glucose of 200 mg/dl are important parameters to monitor but are not as immediately concerning before hemodialysis compared to a high potassium level.
4. A client with a history of chronic kidney disease is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?
- A. Serum potassium
- B. Blood urea nitrogen (BUN)
- C. Serum creatinine
- D. Serum glucose
Correct answer: C
Rationale: Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in assessing kidney function because contrast agents can potentially worsen renal function, leading to contrast-induced nephropathy. Monitoring serum creatinine helps in identifying patients at risk and taking necessary precautions. Serum potassium (Choice A) is important in conditions like hyperkalemia but is not the priority before a contrast CT scan. Blood urea nitrogen (BUN) (Choice B) is another renal function test but is not as specific as serum creatinine for assessing kidney function. Serum glucose (Choice D) is important in monitoring blood sugar levels, especially in diabetic patients, but it is not directly related to the risk of contrast-induced nephropathy in this scenario.
5. A client with a spinal cord injury is admitted to the ICU. Which nursing intervention is most important to include in this client's plan of care?
- A. Monitor for signs of autonomic dysreflexia.
- B. Implement measures to prevent pressure ulcers.
- C. Perform passive range of motion exercises.
- D. Ensure that the client is turned every two hours.
Correct answer: A
Rationale: The correct answer is A: Monitor for signs of autonomic dysreflexia. Autonomic dysreflexia is a life-threatening condition that can occur in clients with spinal cord injuries, especially those with injuries above the T6 level. It is characterized by a sudden onset of excessively high blood pressure, pounding headache, profuse sweating, and flushing above the level of injury. Failure to recognize and treat autonomic dysreflexia promptly can lead to seizures, stroke, or even death. Therefore, monitoring for signs of autonomic dysreflexia is crucial in clients with spinal cord injuries. Choices B, C, and D are important interventions too, but in the context of a spinal cord injury, monitoring for autonomic dysreflexia takes priority due to its potentially life-threatening nature.
