Nursing Elites

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

• A. Remove the patch each evening.
• B. Do not cut the patch in half even if angina attacks are under control.
• C. Take off the nitroglycerin patch if a headache occurs.
• D. Apply a new patch every 48 hours.

Correct answer: A

Rationale: The correct instruction is to remove the nitroglycerin patch each evening to prevent tolerance. This allows for a 10- to 12-hour nitrate-free period daily, reducing the risk of developing tolerance to nitroglycerin. Cutting the patch in half is not recommended because it can alter the dosing and absorption rate, leading to inadequate symptom control. Taking off the patch for a headache is not necessary as headaches are a common side effect that may improve with continued use. Applying a new patch every 48 hours is not correct as it may not provide continuous symptom relief for angina.

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

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

Correct answer: C

Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption. By taking Levothyroxine on an empty stomach, the client ensures optimal absorption and effectiveness of the medication.

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

• A. Take this medication with food.
• B. Avoid drinking grapefruit juice.
• C. Take this medication in the morning.
• D. Increase your intake of potassium-rich foods.

Correct answer: B

Rationale: The correct answer is B: 'Avoid drinking grapefruit juice.' Grapefruit juice can increase the blood levels of Atorvastatin by inhibiting its metabolism in the body, leading to a higher risk of adverse effects, such as muscle pain and liver damage. Therefore, it is important for the client to avoid consuming grapefruit juice while taking Atorvastatin. Choices A, C, and D are incorrect because Atorvastatin can be taken with or without food, at any time of the day, and there is no specific need to increase potassium-rich foods while on this medication.

4. How do ACE inhibitors work?

• A. Block the vasoconstrictor and aldosterone effects of angiotensin II at the receptor site
• B. Block stimulation of beta 1 and beta 2 at the receptor sites
• C. Block the conversion of angiotensin I to the vasoconstrictor angiotensin II
• D. None of the above

Correct answer: C

Rationale: ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, and by blocking its production, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload of the heart. Choice A is incorrect because it describes the mechanism of action of angiotensin receptor blockers (ARBs), not ACE inhibitors. Choice B is incorrect as it describes beta-blockers, not ACE inhibitors. Choice D is incorrect as ACE inhibitors do have a specific mechanism of action.

5. A client has a new prescription for nitroglycerin transdermal patches. Which of the following instructions should the nurse include?

• A. Apply the patch to a different location each day.
• B. Remove the patch every night before bedtime.
• C. Massage the patch area gently after application.
• D. Shave the area before applying the patch.

Correct answer: B

Rationale: The correct instruction for a client using nitroglycerin transdermal patches is to remove the patch every night before bedtime. This practice helps prevent tolerance to the medication's effects. Continuous exposure to nitroglycerin can result in the body becoming less responsive to its therapeutic effects over time, reducing its efficacy in managing the prescribed condition. Choices A, C, and D are incorrect. Applying the patch to a different location each day does not address the issue of tolerance. Massaging the patch area gently after application is not recommended as it may alter drug absorption. Shaving the area before applying the patch is unnecessary and may increase the risk of skin irritation.
