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 client with Addison's disease is receiving corticosteroid therapy. The nurse should monitor the client for which of the following potential side effects?

• A. Hypoglycemia
• B. Hypertension
• C. Weight loss
• D. Hyperkalemia

Correct answer: B

Rationale: When a client with Addison's disease is receiving corticosteroid therapy, the nurse should monitor for hypertension as a potential side effect. Corticosteroids can lead to hypertension by causing fluid retention and increased blood volume. Hypoglycemia (Choice A) is not a common side effect of corticosteroid therapy; instead, hyperglycemia is more likely. Weight loss (Choice C) is not a typical side effect of corticosteroid therapy; in fact, weight gain is more common due to fluid retention and increased appetite. Hyperkalemia (Choice D) is a potential side effect of Addison's disease itself due to adrenal insufficiency, but it is not directly caused by corticosteroid therapy.

3. A client with type 1 diabetes mellitus presents to the emergency department with symptoms of diabetic ketoacidosis (DKA). Which of the following interventions should the nurse implement first?

• 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 first intervention in a client with DKA is to start an intravenous line and infuse normal saline for fluid resuscitation. This is crucial to restore intravascular volume and improve perfusion, addressing the dehydration and electrolyte imbalances commonly seen in DKA. Administering insulin without addressing the dehydration can lead to further complications. Monitoring serum potassium levels is important but is not the first priority; potassium levels can shift with fluid resuscitation. Obtaining an arterial blood gas (ABG) is helpful in assessing acid-base status but is not the initial priority compared to fluid resuscitation.

4. A patient with acute congestive heart failure is receiving high doses of a diuretic. On assessment, the nurse notes flat neck veins, generalized muscle weakness, and diminished deep tendon reflexes. Suspecting hyponatremia, what additional signs would the nurse expect to note in this patient if hyponatremia were present?

• A. Dry skin
• B. Decreased urinary output
• C. Hyperactive bowel sounds
• D. Increased specific gravity of the urine

Correct answer: C

Rationale: In a patient with hyponatremia, hyperactive bowel sounds are expected due to increased gastrointestinal motility. Dry skin (Choice A) is not a typical sign of hyponatremia. Decreased urinary output (Choice B) is more commonly associated with conditions like dehydration or renal issues, not specifically hyponatremia. Increased specific gravity of the urine (Choice D) is a sign of concentrated urine, which is not a characteristic finding in hyponatremia.

5. A nurse is assigned to care for a group of clients. On reviewing the clients' medical records, the nurse determines that which client is at risk for deficient fluid volume?

• A. A client with a colostomy
• B. A client with congestive heart failure
• C. A client with decreased kidney function
• D. A client receiving frequent wound irrigations

Correct answer: A

Rationale: The correct answer is A. Clients with a colostomy are at risk for deficient fluid volume due to the loss of fluid through the colostomy. In colostomy, there can be increased fluid loss through the stoma, which may lead to dehydration and electrolyte imbalances. Choices B, C, and D do not directly relate to the risk for deficient fluid volume. Clients with congestive heart failure are more prone to fluid overload rather than deficient volume. Clients with decreased kidney function are at risk for fluid retention, not deficient volume. Clients receiving frequent wound irrigations may be at risk for infection, but this does not directly indicate deficient fluid volume.
