Nursing Elites

1. Laboratory findings indicate that a client’s serum potassium level is 2.5 mEq/L. What action should the nurse take?

• A. Administer potassium supplements orally.
• B. Increase the client's dietary potassium intake.
• C. Inform the healthcare provider of the need for potassium replacement.
• D. Monitor the client's ECG continuously.

Correct answer: C

Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. In this situation, it is essential for the nurse to inform the healthcare provider promptly about the need for potassium replacement. Administering potassium supplements orally or increasing dietary potassium intake is not appropriate in cases of critically low potassium levels as immediate and precise replacement is necessary. Monitoring the client's ECG continuously is important in severe cases of hypokalemia, but the priority action should be to inform the healthcare provider for further management and treatment.

2. How often should the casts be changed for a newborn with talipes who is wearing casts?

• A. Daily
• B. Weekly
• C. Biweekly
• D. Monthly

Correct answer: B

Rationale: The correct answer is B: Weekly. Treatment of talipes involves manipulation and applying short leg casts. The casts need to be changed weekly to allow for further manipulation and to accommodate the rapid growth of the infant. Changing the casts daily (choice A) would be too frequent and may not provide enough time for the correction to take place. Changing the casts biweekly (choice C) or monthly (choice D) would not provide adequate support for the ongoing correction process required for talipes.

3. Twelve hours following a unilateral total knee replacement, a client reports being unable to sleep because of severe incisional pain. What is the best initial nursing action?

• A. Administer a prescribed sedative.
• B. Reposition the client for comfort.
• C. Apply ice packs to the surgical site.
• D. Instruct the client in the use of the prescribed patient-controlled analgesia (PCA) pump.

Correct answer: D

Rationale: Instructing the client in the use of the PCA pump is the best initial nursing action for managing severe incisional pain after knee replacement surgery. The PCA pump allows the client to self-administer pain medication effectively, promoting better pain management. Administering a sedative may mask the pain temporarily but doesn't address the root cause. Repositioning the client for comfort or applying ice packs may provide some relief but doesn't address the need for effective pain control as the PCA pump does.

4. On the first postoperative day, the nurse finds an older male client disoriented and trying to climb over the bed railing. Previously, he was oriented to person, place, and time on admission. Which intervention should the nurse implement first?

• A. Administer a sedative.
• B. Determine the client’s blood pressure.
• C. Apply soft restraints.
• D. Call for assistance.

Correct answer: B

Rationale: The correct intervention the nurse should implement first is to determine the client’s blood pressure. Assessing the blood pressure is crucial in this situation to rule out physiological causes like hypotension leading to the client's disorientation. Administering a sedative (Choice A) without understanding the underlying cause may worsen the situation. Applying soft restraints (Choice C) should not be the initial action and can be considered later if necessary. Calling for assistance (Choice D) may be needed eventually, but assessing the client's blood pressure takes precedence to address the immediate concern.

5. What is the most common clinical manifestation of coarctation of the aorta?

• A. Clubbing of the digits
• B. Upper extremity hypertension
• C. Pedal edema and portal congestion
• D. Loud systolic ejection murmur

Correct answer: B

Rationale: The correct answer is B: Upper extremity hypertension. Coarctation of the aorta leads to increased blood pressure in the upper extremities. The pressure in the arms is typically 20 mm Hg higher than in the legs. Choice A, clubbing of the digits, is not a common clinical manifestation of coarctation of the aorta. Choice C, pedal edema, and portal congestion are more suggestive of conditions like heart failure rather than coarctation of the aorta. Choice D, loud systolic ejection murmur, can be heard in conditions like aortic stenosis, but it is not the most common clinical manifestation of coarctation of the aorta.
