Nursing Elites

1. The patient expects that a type 1 diabetic may receive ____ of their morning dose of insulin preoperatively:

• A. 10-20%.
• B. 25-40%.
• C. 50-60%.
• D. 85-90%.

Correct answer: B

Rationale: It is common practice to administer 25-40% of the morning dose of insulin preoperatively to prevent hypoglycemia during surgery. Giving a lower percentage (A) may not provide sufficient glycemic control, while higher percentages (C, D) can increase the risk of hypoglycemia during the surgical procedure.

2. A nurse caring for a client with hypocalcemia would expect to note which of the following changes on the electrocardiogram?

• A. Widened T wave
• B. Prominent U wave
• C. Prolonged QT interval
• D. Shortened ST segment

Correct answer: C

Rationale: In hypocalcemia, a decreased level of calcium can lead to a prolonged QT interval on the ECG due to its role in myocardial repolarization. A widened T wave (Choice A) is typically seen in hyperkalemia. A prominent U wave (Choice B) is associated with hypokalemia. A shortened ST segment (Choice D) is not a typical ECG finding in hypocalcemia.

3. A client with hypothyroidism is receiving levothyroxine therapy. The healthcare provider should monitor for which of the following signs of medication overdose?

• A. Bradycardia
• B. Weight gain
• C. Tachycardia
• D. Cold intolerance

Correct answer: C

Rationale: The correct answer is C: Tachycardia. Tachycardia is a sign of levothyroxine overdose, indicating that the dose may need to be adjusted. Bradycardia (Choice A) is a sign of hypothyroidism, not an overdose of levothyroxine. Weight gain (Choice B) and cold intolerance (Choice D) are also symptoms of hypothyroidism, not medication overdose.

4. Effective leaders must communicate a vision for the future. Which of the following is the best method for communicating a vision for the future?

• A. Involve others in creating the vision and connect daily work tasks to the vision.
• B. Encourage staff nurses to openly discuss practice and possible improvements.
• C. Critically analyze and discuss advances in practice with other nurses on staff.
• D. Actively listen to the recommendations of others.

Correct answer: A

Rationale: The best method for communicating a vision for the future is to involve others in creating the vision and connect daily work tasks to the vision. This approach fosters ownership and commitment among team members, as they feel part of the vision-building process and understand how their daily tasks contribute to achieving that vision. Choice B, encouraging staff nurses to openly discuss practice and possible improvements, is important for fostering communication but doesn't directly address creating and communicating a vision. Choice C, critically analyzing and discussing advances in practice with other nurses, focuses on professional development and knowledge sharing rather than specifically communicating a future vision. Choice D, actively listening to recommendations, is valuable for gathering input but may not be sufficient on its own for effectively communicating a future vision.

5. 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.
