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 caring for a client prescribed Digoxin, which finding should the nurse monitor to assess for potential toxicity?

• A. Bradycardia
• B. Hypertension
• C. Hypoglycemia
• D. Hypercalcemia

Correct answer: A

Rationale: Bradycardia is a common sign of Digoxin toxicity. Digoxin, a cardiac glycoside, can lead to toxic effects such as bradycardia, which is a slow heart rate. Therefore, the nurse should closely monitor the client's heart rate for any significant decreases, as this could indicate Digoxin toxicity and prompt further intervention. Choices B, C, and D are incorrect because Digoxin toxicity typically presents with bradycardia, not hypertension, hypoglycemia, or hypercalcemia.

3. When assessing a client taking Gemfibrozil, which of the following findings should the nurse identify as an adverse reaction to the medication?

• A. Mental status changes
• B. Tremor
• C. Jaundice
• D. Pneumonia

Correct answer: C

Rationale: Jaundice is an adverse reaction that can occur in clients taking Gemfibrozil due to the potential development of liver impairment. Other symptoms of liver impairment may include anorexia and upper abdominal discomfort. Monitoring for signs of jaundice is crucial to detect and manage adverse effects of the medication promptly. Mental status changes (choice A) are not commonly associated with Gemfibrozil use. Tremor (choice B) is not a typical adverse reaction of Gemfibrozil. Pneumonia (choice D) is not directly linked to Gemfibrozil use but can be a complication in some cases.

4. A client has a new prescription for a Nitroglycerin transdermal patch. Which of the following instructions should the nurse include?

• A. Apply the patch to the same site each day.
• B. Remove the patch at night.
• C. Cover the patch with a heating pad.
• D. Apply the patch to a hairless area of skin.

Correct answer: D

Rationale: The correct instruction is to apply the Nitroglycerin transdermal patch to a hairless area of skin. This is important for proper absorption of the medication. Additionally, rotating the patch to different sites each day helps prevent skin irritation and ensures optimal therapeutic effect. Applying the patch to the same site each day can lead to skin irritation or tolerance development. Removing the patch at night is not necessary as the patch is typically worn continuously to provide a consistent level of medication. Covering the patch with a heating pad is contraindicated as it can increase drug absorption, potentially leading to adverse effects.

5. Which medication is a beta blocker?

• A. Atenolol (Tenormin)
• B. Verapamil (Calan)
• C. Captopril (Capoten)
• D. Clopidogrel (Plavix)

Correct answer: A

Rationale: Atenolol (Tenormin) is a beta blocker commonly used to treat conditions like hypertension and angina by blocking the action of adrenaline on the heart. Verapamil is a calcium channel blocker, Captopril is an ACE inhibitor, and Clopidogrel is an antiplatelet medication. Therefore, the correct answer is Atenolol (Tenormin) as it belongs to the beta blocker class of medications.
