Nursing Elites

1. What is a severe adverse effect of warfarin?

• A. Bleeding
• B. Arrhythmias
• C. Blurred vision
• D. Bradycardia

Correct answer: A

Rationale: A severe adverse effect of warfarin is bleeding. Warfarin is an anticoagulant medication that works by inhibiting blood clotting factors, which can lead to an increased risk of bleeding. Excessive bleeding can occur internally or externally, and it is crucial for individuals taking warfarin to be aware of this potential complication and seek medical attention if they experience any signs of bleeding. Arrhythmias, blurred vision, and bradycardia are not typically associated with warfarin use, making them incorrect choices.

2. A client has a prescription for Clindamycin. Which of the following instructions should the nurse include?

• A. Take the medication with a full glass of water.
• B. Avoid taking the medication with food.
• C. Discontinue the medication if diarrhea occurs.
• D. Expect to have increased appetite while taking this medication.

Correct answer: A

Rationale: The correct instruction for a client taking Clindamycin is to take the medication with a full glass of water. Clindamycin can cause esophageal irritation, so taking it with a full glass of water helps minimize this risk. Avoiding taking the medication with food is not necessary. If diarrhea occurs, clients should not discontinue the medication without consulting their healthcare provider. Clindamycin is not known to cause increased appetite.

3. A client has a new prescription for Verapamil. Which of the following instructions should the nurse include?

• A. Take this medication at bedtime.
• B. Monitor for signs of hyperglycemia.
• C. Avoid drinking grapefruit juice.
• D. Increase your intake of potassium-rich foods.

Correct answer: C

Rationale: The correct answer is to instruct the client to avoid drinking grapefruit juice. Grapefruit juice can inhibit the metabolism of Verapamil, leading to increased blood levels of the medication, which can potentiate its effects, potentially causing adverse reactions like hypotension and bradycardia. Choices A, B, and D are incorrect. Taking Verapamil at bedtime is not a specific instruction related to its metabolism or side effects. Monitoring for signs of hyperglycemia is not directly related to Verapamil use. Increasing potassium-rich foods intake is not necessary with Verapamil and could potentially lead to hyperkalemia in some cases.

4. Which of the following is a potassium-sparing diuretic?

• A. Furosemide
• B. Spironolactone
• C. Hydrochlorothiazide
• D. Bumetanide

Correct answer: B

Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by antagonizing the aldosterone receptor, leading to potassium retention and sodium excretion. This mechanism makes it a suitable choice for conditions where potassium retention is desired, such as in patients with heart failure or liver cirrhosis. Choices A, C, and D are not potassium-sparing diuretics. Furosemide, hydrochlorothiazide, and bumetanide are loop diuretics and thiazide diuretics, respectively, which promote the excretion of potassium.

5. When educating a client who has a prescription for Levothyroxine, which instruction should the nurse include?

• A. Take this medication on an empty stomach.
• B. Take this medication with food.
• C. Take this medication at bedtime.
• D. Take this medication with antacids.

Correct answer: A

Rationale: The correct instruction for taking Levothyroxine is on an empty stomach. This helps to enhance the absorption and effectiveness of the medication. Consuming it with food or antacids can impede its absorption, leading to decreased efficacy.
