Nursing Elites

1. 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.

2. A nurse is teaching a client who has a new prescription for Atenolol. Which of the following adverse effects should the nurse instruct the client to monitor?

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

Correct answer: C

Rationale: Atenolol is a beta-blocker that can cause bradycardia as an adverse effect. The client should monitor their pulse regularly and report any significant decreases.

3. What is the action of Metformin?

• A. Decreasing intestinal glucose absorption
• B. Increasing sensitivity to insulin
• C. Decreasing hepatic glucose production
• D. All of the above

Correct answer: D

Rationale: Metformin exerts its effects by decreasing hepatic glucose production, increasing sensitivity to insulin, and decreasing intestinal glucose absorption. These actions help in lowering blood glucose levels and improving insulin sensitivity in individuals with diabetes.

4. A client has a new prescription for radioactive iodine to treat Hyperthyroidism. Which of the following instructions should the nurse include?

• A. Expect a metallic taste in the mouth.
• B. Avoid contact with pregnant women for 1 week.
• C. Administer iodine solution using a straw.
• D. Take thyroid replacement medication for 3 weeks after treatment.

Correct answer: B

Rationale: When a client undergoes radioactive iodine treatment for hyperthyroidism, they can emit radiation for a short time. To prevent radiation exposure to others, especially pregnant women, infants, and small children, clients should avoid close contact for about 1 week following therapy. This precaution is essential to protect vulnerable individuals from potential harm. Choice A is incorrect because a metallic taste in the mouth is not a common side effect of radioactive iodine treatment. Choice C is incorrect because administering iodine solution using a straw is not a standard practice in this treatment. Choice D is incorrect because taking thyroid replacement medication for 3 weeks after treatment is not a typical instruction associated with radioactive iodine therapy for hyperthyroidism.

5. 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 ensures proper absorption of the medication. It is important to rotate the application site daily to prevent skin irritation and tolerance development. Applying the patch to the same site each day can lead to decreased efficacy and potential skin reactions. Removing the patch at night is not necessary as the patches are usually worn continuously to provide constant medication delivery. Covering the patch with a heating pad can increase the absorption of the medication and lead to an overdose, which is not recommended.
