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

• A. Drink 2 liters of water daily.
• B. Avoid taking the medication on an empty stomach.
• C. Limit vitamin C intake while taking this medication.
• D. Take an iron supplement while on this medication.

Correct answer: A

Rationale: The correct instruction for a client prescribed allopurinol is to drink 2 liters of water daily. This helps reduce the risk of kidney stones, a potential side effect of allopurinol use. Adequate hydration is essential to prevent kidney stone formation and maintain kidney function while taking this medication.

3. A client is to receive Pamidronate for bone pain related to cancer. What precaution should the nurse take during the administration of Pamidronate?

• A. Inspect the skin for redness and irritation around the injection site.
• B. Assess the IV site for thrombophlebitis frequently during administration.
• C. Instruct the client to lie down for 30 minutes after oral administration.
• D. Monitor for signs of anaphylaxis for 20 minutes after intramuscular injection.

Correct answer: B

Rationale: Pamidronate is typically administered through IV infusion, which can cause irritation to veins. The nurse should frequently assess the IV site for thrombophlebitis during the administration to promptly detect any potential complications related to the infusion. Inspecting the skin for redness and irritation around the injection site (Choice A) is not directly related to IV infusion. Instructing the client to lie down after oral administration (Choice C) is not necessary for IV administration. Monitoring for signs of anaphylaxis after an intramuscular injection (Choice D) is not relevant for an IV infusion of Pamidronate.

4. A healthcare professional is caring for a group of clients receiving antimicrobial therapy. Which of the following clients should the professional plan to monitor for manifestations of antibiotic toxicity?

• A. An adolescent client with a sinus infection
• B. An older adult client with prostatitis
• C. A client who is postpartum with mastitis
• D. A middle-aged client with a urinary tract infection

Correct answer: B

Rationale: An older adult client with prostatitis who is receiving antibiotics should be monitored for toxicity due to age-related reductions in medication metabolism and excretion. Older adults are more susceptible to antibiotic toxicity, making them a high-risk group for adverse effects.

5. A client is admitted for a surgical procedure. Which preexisting condition can be a contraindication for the use of Ketamine as an intravenous anesthetic?

• A. Peptic ulcer disease
• B. Breast cancer
• C. Diabetes mellitus
• D. Schizophrenia

Correct answer: D

Rationale: Ketamine can produce psychological effects like hallucinations. Patients with schizophrenia may be more prone to experiencing exacerbation of their symptoms when exposed to Ketamine due to its potential to worsen psychotic symptoms. Therefore, schizophrenia can be a contraindication for the use of Ketamine as an anesthetic. Peptic ulcer disease, breast cancer, and diabetes mellitus are not contraindications for the use of Ketamine.
