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.

The nurse and an unlicensed nursing assistant are caring for a group of clients. Which nursing intervention should the nurse perform?
- A. Measure the client's output from the indwelling catheter.
- B. Record the client's intake and output on the I & O sheet.
- C. Instruct the client on appropriate fluid restrictions.
- D. Provide water for a client diagnosed with diabetes insipidus.
Correct Answer: C
Rationale: Instructing the client on appropriate fluid restrictions is a nursing intervention that requires professional judgment and should be performed by the nurse. In this scenario, the nurse should provide education regarding fluid restrictions based on the client's individual needs. Measuring the client's output from the indwelling catheter (choice A) and recording intake and output (choice B) can be tasks delegated to the unlicensed nursing assistant. Providing water for a client diagnosed with diabetes insipidus (choice D) is not appropriate as these clients often require careful fluid management to prevent complications.
The client with type 2 DM is being taught about the importance of foot care. Which instruction should be included?
- A. Soak your feet in hot water every night.
- B. Walk barefoot whenever possible.
- C. Use a heating pad to warm your feet.
- D. Wear comfortable shoes that allow air circulation.
Correct Answer: D
Rationale: The correct instruction for the client with type 2 DM regarding foot care is to wear comfortable shoes that allow air circulation. This helps prevent foot injuries and infections, which are common complications in clients with diabetes. Choice A is incorrect as soaking feet in hot water can lead to burns and skin damage. Choice B is incorrect because walking barefoot increases the risk of injury and infection. Choice C is incorrect as using a heating pad can also potentially lead to burns and skin damage.
A healthcare professional reviews a client's electrolyte laboratory report and notes that the potassium level is 3.2 mEq/L. Which of the following would the healthcare professional note on the electrocardiogram as a result of the laboratory value?
- A. U waves
- B. Absent P waves
- C. Elevated T waves
- D. Elevated ST segment
Correct Answer: A
Rationale: The correct answer is A: U waves. A low potassium level (hypokalemia) can manifest as U waves on an ECG. U waves are small, extra deflections seen after the T wave and may indicate cardiac irritability. Absent P waves (Choice B) are associated with conditions like atrial fibrillation. Elevated T waves (Choice C) can be seen in hyperkalemia, not hypokalemia. Elevated ST segment (Choice D) is not typically associated with low potassium levels but can be seen in conditions like myocardial infarction.
What is the nurse manager's role in improving the quality of care on the unit?
- A. The nurse manager is responsible for setting goals and priorities for the unit and ensuring that staff members are working towards achieving those goals.
- B. The nurse manager is responsible for monitoring patient outcomes and implementing changes to improve the quality of care on the unit.
- C. The nurse manager is responsible for ensuring that staff members follow established procedures and protocols to maintain the quality of care on the unit.
- D. The nurse manager is responsible for providing feedback and coaching to staff members to help them improve their performance and achieve the unit's quality goals.
Correct Answer: A
Rationale: The nurse manager plays a crucial role in improving the quality of care on the unit by setting goals and priorities for the unit and ensuring that staff members are working towards achieving those goals. This involves strategic planning, coordination, and leadership to guide the team in delivering high-quality patient care. Option B is incorrect as while monitoring patient outcomes is important, it is not the primary role of the nurse manager in improving care quality. Option C is incorrect because while ensuring staff adherence to procedures is important, it is a part of maintaining quality rather than actively improving it. Option D is incorrect as providing feedback and coaching, though essential, is not the primary role of the nurse manager in setting goals and priorities for quality improvement.
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.
