1. 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.
2. A client with active tuberculosis asks why he must take four different medications. Which of the following responses should the nurse make?
- A. Taking four medications decreases the risk of a severe allergic reaction.
- B. Taking four medications reduces the chance that the bacteria will become resistant.
- C. Taking four medications reduces the risk of adverse reactions.
- D. Taking four medications decreases the chance of having a positive tuberculin skin test.
Correct answer: B
Rationale: When treating tuberculosis, using a combination of multiple medications is crucial to reduce the risk of bacterial resistance. The use of four medications helps to target the bacteria from different angles, making it harder for them to develop resistance to the treatment. This approach is essential to ensure the effectiveness of the treatment regimen and to prevent the spread of drug-resistant strains of tuberculosis. Choices A, C, and D are incorrect because the primary reason for using multiple medications in tuberculosis treatment is to prevent the development of bacterial resistance, not to decrease the risk of allergic reactions, adverse reactions, or affecting the tuberculin skin test results.
3. A client has a new prescription for clonidine to treat hypertension. Which of the following instructions should the nurse include?
- A. Discontinue the medication if a rash develops.
- B. Expect increased salivation during the first few weeks of therapy.
- C. Avoid driving until the client's reaction to the medication is known.
- D. Stop the medication if you experience a dry mouth.
Correct answer: C
Rationale: The correct instruction for a client starting clonidine therapy for hypertension is to avoid driving until their reaction to the medication is known. Clonidine can cause drowsiness, so it is important for the client to refrain from activities that require alertness until they are aware of how the medication affects them. Choice A is incorrect because a rash is not a common side effect of clonidine. Choice B is incorrect as increased salivation is not an expected side effect of clonidine. Choice D is also incorrect as dry mouth is a common side effect of clonidine, but it is not a reason to stop the medication unless severe or bothersome. Therefore, the priority instruction for the nurse to include is to advise the client to avoid driving until their reaction to the medication is known to ensure safety.
4. A client is being discharged with a new prescription for Atenolol. Which of the following instructions should the nurse include?
- A. Take this medication in the morning.
- B. Monitor your heart rate regularly.
- C. Avoid consuming foods high in potassium.
- D. Increase your fluid intake.
Correct answer: B
Rationale: The correct answer is B: 'Monitor your heart rate regularly.' Atenolol is a beta-blocker that can cause bradycardia (slow heart rate). Monitoring the heart rate regularly is crucial to promptly detect any significant decreases. This allows for timely intervention and adjustment of the medication regimen if needed, helping to prevent adverse effects associated with bradycardia. Choices A, C, and D are incorrect. Instructing the client to take the medication in the morning does not address the need for heart rate monitoring. Avoiding foods high in potassium is more relevant for medications like ACE inhibitors or potassium-sparing diuretics. Increasing fluid intake is not directly related to the use of Atenolol.
5. 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.
