Nursing Elites

1. 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.

2. A healthcare provider caring for a client with severe malnutrition reviews the laboratory results and notes a magnesium level of 1.0 mg/dL. Which electrocardiographic change would the healthcare provider expect to note based on the magnesium level?

• A. Prominent U waves
• B. Prolonged PR interval
• C. Depressed ST segment
• D. Widened QRS complexes

Correct answer: C

Rationale: A magnesium level of 1.0 mg/dL can cause a depressed ST segment on the ECG. Magnesium deficiency commonly leads to ST segment depression on an electrocardiogram. Prominent U waves are associated with hypokalemia, prolonged PR interval is seen in conditions like first-degree heart block, and widened QRS complexes are typically related to conditions affecting the conduction system of the heart, such as bundle branch blocks.

3. A client with type 1 DM is admitted to the hospital with diabetic ketoacidosis (DKA). The nurse should prioritize which action?

• A. Administering intravenous fluids.
• B. Administering oral glucose.
• C. Administering a fever-reducing medication.
• D. Administering oxygen therapy.

Correct answer: A

Rationale: Administering intravenous fluids is the priority in treating DKA for several reasons. DKA is characterized by severe dehydration and electrolyte imbalances due to hyperglycemia. IV fluids help to correct dehydration, restore electrolyte balance, and decrease blood glucose levels. Administering oral glucose (Choice B) would be contraindicated in DKA as the primary issue is high blood glucose levels. Administering a fever-reducing medication (Choice C) is not the priority in managing DKA. Administering oxygen therapy (Choice D) may be necessary in some cases, but correcting dehydration and electrolyte imbalances take precedence in the management of DKA.

4. Nurse Kate is providing dietary instructions to a male client with hypoglycemia. To control hypoglycemic episodes, the nurse should recommend:

• A. Increasing saturated fat intake and fasting in the afternoon
• B. Increasing intake of vitamins B and D and taking iron supplements
• C. Eating a candy bar if lightheadedness occurs
• D. Consuming a low-carbohydrate, high-protein diet and avoiding fasting

Correct answer: D

Rationale: A low-carbohydrate, high-protein diet is beneficial for individuals with hypoglycemia as it helps in maintaining stable blood sugar levels. Choice A is incorrect as increasing saturated fat intake and fasting can worsen hypoglycemia. Choice B is incorrect as vitamins and iron supplements do not directly address hypoglycemia. Choice C is incorrect as consuming a candy bar may provide temporary relief but does not address the underlying cause of hypoglycemia.

5. Which of the following best describes the role of a nurse manager in managing conflict on the unit?

• A. The nurse manager is responsible for identifying the sources of conflict and working with staff members to resolve them in a constructive manner.
• B. The nurse manager is responsible for mediating conflicts between staff members and ensuring that they are resolved in a fair and equitable manner.
• C. The nurse manager is responsible for facilitating communication between staff members and ensuring that conflicts are addressed in a timely manner.
• D. The nurse manager is responsible for providing training and support to staff members to help them develop the skills needed to manage conflict effectively.

Correct answer: A

Rationale: The nurse manager's role in managing conflict involves identifying the sources of conflict and working with staff members to resolve them in a constructive manner. This includes addressing conflicts at their root cause and guiding staff towards effective resolution. Choice B is incorrect as the nurse manager typically does not act as a mediator but rather empowers staff to resolve conflicts themselves. Choice C is incorrect as while facilitating communication is important, it is not the sole responsibility of the nurse manager. Choice D is incorrect as providing training and support for conflict management is part of the role, but the primary responsibility lies in addressing the sources of conflict directly.
