Nursing Elites

1. A patient taking isotretinoin (Accutane) for acne vulgaris. Which statement indicates that the patient teaching has been effective?

• A. I should use a reliable form of birth control.
• B. I will stop taking the drug if my skin is dry.
• C. It is important to increase intake of vitamin A.
• D. I do not need to use sunblock while taking Accutane.

Correct answer: A

Rationale: The correct answer is A. Isotretinoin is highly teratogenic, which means it can cause birth defects. Therefore, it is crucial for patients, especially females of childbearing potential, to use effective forms of birth control to prevent pregnancy while taking this medication. This is a key component of patient teaching to ensure the safe use of isotretinoin. Choice B is incorrect because discontinuing isotretinoin abruptly can lead to a flare-up of acne. Choice C is incorrect because increasing vitamin A intake can be harmful due to the risk of hypervitaminosis A. Choice D is incorrect because isotretinoin makes the skin more sensitive to sunlight, so sunblock is essential to prevent sunburn and skin damage.

2. A child is admitted to the hospital for hypercalcemia and is placed on diuretic therapy. Which diuretic would the nurse expect to administer?

• A. Furosemide (Lasix)
• B. Hydrochlorothiazide (Aquazide)
• C. Spironolactone (Aldactone)
• D. Mannitol (Osmitrol)

Correct answer: A

Rationale: Furosemide (Lasix) is a loop diuretic that acts on the ascending loop of Henle in the kidney to increase calcium excretion. In the setting of hypercalcemia, where there is an elevated level of calcium in the blood, Furosemide can help promote the elimination of excess calcium through the urine, thereby aiding in the management of hypercalcemia.

3. A nasogastric tube for suction is ordered for a neonate diagnosed with a diaphragmatic hernia. Which complication related to gastric drainage is the priority when planning care for this neonate?

• A. Weight loss
• B. Metabolic alkalosis
• C. Dehydration
• D. Hyperbilirubinemia

Correct answer: B

Rationale: Metabolic alkalosis is the priority complication to consider when a neonate with a diaphragmatic hernia is placed on gastric suction. Prolonged gastric drainage can lead to the loss of stomach acids, resulting in metabolic alkalosis, which can have serious consequences for the neonate's health.

4. The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure?

• A. Angiotensin I
• B. Angiotensin II
• C. Angiotensin III
• D. Renin

Correct answer: B

Rationale: Angiotensin II is the most potent compound in the renin-angiotensin-aldosterone system for raising blood pressure. It acts as a powerful vasoconstrictor, leading to increased systemic vascular resistance. Angiotensin II is formed from angiotensin I through the action of the angiotensin-converting enzyme. While renin initiates the cascade by converting angiotensinogen to angiotensin I, it is angiotensin II that exerts the strongest pressor effect.

5. Which menu choices for a child diagnosed with renal failure and experiencing hyperkalemia indicate the need for further instruction by the nurse?

• A. Carrots and green, leafy vegetables
• B. Spaghetti and meat sauce with breadsticks
• C. Hamburger on a bun and cherry gelatin
• D. Chips, cold cuts, and canned foods

Correct answer: A

Rationale: Carrots and green, leafy vegetables are high in potassium, which should be avoided in hyperkalemia. Therefore, this choice requires further instruction by the nurse to prevent exacerbating the child's condition.
