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 type 1 DM is experiencing hypoglycemia. Which symptom should the nurse expect to observe?

• A. Tachycardia
• B. Polyuria
• C. Flushed skin
• D. Dry mouth

Correct answer: A

Rationale: The correct answer is A: Tachycardia. In hypoglycemia, the body releases adrenaline in response to low blood glucose levels, leading to symptoms such as tachycardia (rapid heart rate). Choice B, polyuria, refers to excessive urination and is not a typical symptom of hypoglycemia. Choice C, flushed skin, is not a common symptom of hypoglycemia; instead, pale skin and sweating are more characteristic. Choice D, dry mouth, is not directly associated with hypoglycemia; rather, it can be a symptom of hyperglycemia or dehydration.

3. A client with hyperthyroidism is prescribed propranolol. The nurse explains that this medication is used to:

• A. Increase thyroid hormone production
• B. Decrease thyroid hormone production
• C. Relieve symptoms such as tachycardia and anxiety
• D. Prevent weight loss

Correct answer: C

Rationale: Propranolol is a beta-blocker that works by blocking the effects of adrenaline, which helps to reduce symptoms such as tachycardia (fast heart rate) and anxiety in individuals with hyperthyroidism. Choices A and B are incorrect because propranolol does not affect thyroid hormone production; it only addresses symptoms. Choice D is incorrect because propranolol does not prevent weight loss associated with hyperthyroidism.

4. A healthcare professional is reading a physician's progress notes in the client's record and reads that the physician has documented 'insensible fluid loss of approximately 800 mL daily.' The healthcare professional understands that this type of fluid loss can occur through:

• A. The skin
• B. Urinary output
• C. Wound drainage
• D. The gastrointestinal tract

Correct answer: A

Rationale: Insensible fluid loss refers to the fluid lost from the body that is not easily measured, such as through sweating and respiration. The skin is a major contributor to insensible fluid loss due to evaporation of water through the skin. Choice B, urinary output, represents measurable fluid loss through urine excretion. Choice C, wound drainage, is a measurable form of fluid loss that occurs externally from a wound. Choice D, the gastrointestinal tract, primarily involves fluid loss through feces and is also a measurable form of output. Therefore, the correct answer is 'A: The skin,' as it is the main route for insensible fluid loss.

5. A client with diabetes mellitus is receiving an oral antidiabetic medication. The nurse should monitor for which of the following adverse effects?

• A. Weight gain
• B. Hypoglycemia
• C. Hyperglycemia
• D. Bradycardia

Correct answer: B

Rationale: The correct answer is B: Hypoglycemia. When a client with diabetes mellitus is taking oral antidiabetic medication, the nurse should closely monitor for hypoglycemia, which is a common adverse effect. Hypoglycemia occurs when the blood sugar levels drop below normal range, leading to symptoms like confusion, shakiness, and sweating. Weight gain (Choice A) is not a typical adverse effect of oral antidiabetic medications. Hyperglycemia (Choice C) is the opposite of the desired effect of antidiabetic medications, which aim to lower blood sugar levels. Bradycardia (Choice D) is not directly associated with oral antidiabetic medications; it refers to a slow heart rate.
