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 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.

3. A client with diabetes mellitus is being educated on the importance of foot care. Which of the following instructions should the nurse include?

• A. Soak your feet daily to maintain cleanliness.
• B. Wear tight-fitting shoes to protect your feet.
• C. Apply lotion between your toes to prevent dryness.
• D. Inspect your feet daily for any cuts or sores.

Correct answer: D

Rationale: The correct answer is to instruct the client to inspect their feet daily for any cuts or sores. This is crucial for individuals with diabetes as they are at a higher risk of developing foot problems. Soaking feet daily can lead to skin breakdown and infections, making choice A incorrect. Tight-fitting shoes can cause pressure points and increase the risk of foot injuries, so choice B is incorrect. Applying lotion between the toes can create a moist environment, increasing the risk of fungal infections, making choice C incorrect.

4. A client with hyperaldosteronism is at risk for which of the following electrolyte imbalances?

• A. Hyperkalemia
• B. Hyponatremia
• C. Hypokalemia
• D. Hypercalcemia

Correct answer: C

Rationale: In hyperaldosteronism, there is an excessive secretion of aldosterone, a hormone that promotes potassium excretion in the kidneys. This leads to low potassium levels in the blood, known as hypokalemia. Therefore, the correct answer is hypokalemia (Choice C). Hyperkalemia (Choice A) is the opposite condition, where there is high potassium levels in the blood and is not typically associated with hyperaldosteronism. Hyponatremia (Choice B) is a low sodium level, which is not directly related to aldosterone function. Hypercalcemia (Choice D) is an elevated calcium level and is not typically a direct result of hyperaldosteronism.

5. The client with hypothyroidism is being educated by the healthcare provider about taking levothyroxine. Which of the following instructions should be included?

• A. Take the medication with meals
• B. Take the medication at bedtime
• C. Take the medication on an empty stomach in the morning
• D. Take the medication with a glass of milk

Correct answer: C

Rationale: The correct answer is to take levothyroxine on an empty stomach in the morning. This instruction is essential to enhance absorption and efficacy of the medication. Taking levothyroxine with meals, at bedtime, or with a glass of milk can interfere with its absorption and effectiveness, leading to suboptimal treatment outcomes.
