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 nurse manager has detected a potential problem with staffing and has asked staff members for their thoughts on the matter. Which of the following best describes the informational activity this manager is engaging in?

• A. Spokesperson
• B. Reporting
• C. Monitoring
• D. Job analysis and redesign

Correct answer: C

Rationale: The correct answer is C: 'Monitoring.' Monitoring involves regularly checking and observing the status of a unit or situation. In this scenario, the nurse manager is actively seeking feedback from staff members to assess and keep track of the staffing situation. Choice A, 'Spokesperson,' refers to a role where someone represents or speaks on behalf of a group or organization, which is not the primary activity in this case. Choice B, 'Reporting,' typically involves presenting information or data about a specific topic or issue but does not capture the ongoing observation and assessment aspect seen in monitoring. Choice D, 'Job analysis and redesign,' involves assessing and restructuring job roles, responsibilities, and tasks, which is not directly related to the action of monitoring staffing levels.

3. A nurse is preparing to administer NPH insulin to a client with DM. The nurse notes that the NPH insulin vial is cloudy. The nurse should:

• A. Obtain a new vial of NPH insulin.
• B. Draw up the cloudy insulin as ordered.
• C. Shake the vial vigorously before drawing up the insulin.
• D. Warm the insulin to room temperature before administration.

Correct answer: B

Rationale: The correct answer is to draw up the cloudy insulin as ordered. NPH insulin is inherently cloudy due to its suspension of insulin crystals. Shaking the vial vigorously can lead to denaturation of the insulin molecules, altering its efficacy. Warming NPH insulin is not necessary as it can cause breakdown of insulin molecules. The nurse should gently roll the vial between hands to mix it before drawing it up to ensure an even distribution of insulin in the suspension.

4. The healthcare provider is monitoring a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following interventions should the healthcare provider include in the care plan?

• A. Encourage oral fluids
• B. Restrict fluid intake
• C. Administer potassium supplements
• D. Increase sodium intake

Correct answer: B

Rationale: The correct intervention for a client with SIADH is to restrict fluid intake. SIADH leads to water retention and dilution of sodium levels in the body, resulting in hyponatremia. Restricting fluid intake helps prevent further dilutional hyponatremia. Encouraging oral fluids (Choice A) would exacerbate the condition by further increasing fluid retention. Administering potassium supplements (Choice C) is not directly related to managing SIADH. Increasing sodium intake (Choice D) is contraindicated because it can worsen hyponatremia in clients with SIADH.

5. A client with type 1 diabetes mellitus is admitted with diabetic ketoacidosis (DKA). Which of the following interventions should be the nurse's priority?

• A. Administer intravenous insulin
• B. Start an intravenous line and infuse normal saline
• C. Monitor serum potassium levels
• D. Obtain an arterial blood gas (ABG)

Correct answer: B

Rationale: The correct answer is to start an intravenous line and infuse normal saline. In diabetic ketoacidosis (DKA), the priority intervention is fluid resuscitation with normal saline to restore intravascular volume and improve perfusion. Administering insulin without first addressing dehydration and electrolyte imbalances can lead to further complications. Monitoring serum potassium levels and obtaining an arterial blood gas (ABG) are important aspects of DKA management but come after initial fluid resuscitation.
