Nursing Elites

1. What is the primary action of warfarin as an anticoagulant?

• A. Prevents the formation of blood clots
• B. Dissolves existing blood clots
• C. Dilates coronary arteries
• D. Treats rhythm disturbances

Correct answer: A

Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.

2. When administering IV Acyclovir to a client with Varicella, what action should the nurse take?

• A. Administer a stool softener
• B. Decrease fluid intake following infusion
• C. Infuse Acyclovir over 1 hr
• D. Monitor for hypotension

Correct answer: C

Rationale: When administering IV Acyclovir to a client with Varicella, the nurse should infuse the medication over at least 1 hour to prevent nephrotoxicity. Rapid infusion can lead to adverse effects such as renal damage. Therefore, it is crucial to follow the recommended infusion rate to ensure the client's safety and well-being. Choice A is incorrect as stool softeners are not indicated in this situation. Choice B is incorrect because fluid intake should be maintained or increased to prevent dehydration and support kidney function. Choice D is incorrect as monitoring for hypotension is not specifically related to the administration of IV Acyclovir in Varicella.

3. What is levothyroxine's pharmacologic classification?

• A. Thyroid Preparations
• B. Metabolic Inhibitors
• C. Analgesic
• D. Loop Diuretic

Correct answer: A

Rationale: Levothyroxine is classified as a thyroid preparation because it is a synthetic form of the thyroid hormone thyroxine. It is primarily used to treat hypothyroidism by supplementing or replacing the natural thyroid hormones in the body, helping to regulate metabolism and energy levels. Choice B, Metabolic Inhibitors, is incorrect because levothyroxine does not inhibit metabolism but rather helps regulate it. Choice C, Analgesic, is incorrect as levothyroxine is not used for pain relief but for thyroid hormone replacement therapy. Choice D, Loop Diuretic, is also incorrect as loop diuretics are medications that act on the kidneys to increase urine production and are not related to thyroid hormone replacement therapy.

4. A client has a new prescription for Verapamil to control hypertension. Which of the following instructions should the nurse include?

• A. Increase the amount of dietary fiber in the diet.
• B. Drink grapefruit juice daily to increase vitamin C intake.
• C. Decrease the amount of calcium in the diet.
• D. Withhold food for 1 hr after taking the medication.

Correct answer: A

Rationale: Increasing dietary fiber intake is essential when taking Verapamil to prevent constipation, a common adverse effect of this medication. Verapamil is a calcium channel blocker used to treat hypertension, and dietary fiber helps maintain bowel regularity and prevent constipation that may occur as a side effect of the medication.

5. A client has a new prescription for spironolactone. The client should avoid which of the following foods?

• A. Salt substitutes
• B. Apples
• C. Chicken
• D. Bananas

Correct answer: A

Rationale: Spironolactone is a potassium-sparing diuretic. Clients prescribed spironolactone should avoid salt substitutes because they often contain potassium. Increased potassium intake can lead to hyperkalemia, which is a potential side effect of spironolactone.
