Nursing Elites

1. A client is taking Amiodarone to treat Atrial Fibrillation. Which of the following findings is a manifestation of Amiodarone toxicity?

• A. Light yellow urine
• B. Report of tinnitus
• C. Productive cough
• D. Blue-gray skin discoloration

Correct answer: D

Rationale: Blue-gray skin discoloration is a common sign of Amiodarone toxicity, known as blue-gray discoloration, which can affect areas like the face, neck, or hands. It is important to monitor for this side effect, as it can be a visible indicator of potential toxicity. Choices A, B, and C are incorrect. Light yellow urine is not typically associated with Amiodarone toxicity. Tinnitus is not a common manifestation of Amiodarone toxicity. A productive cough is not a recognized symptom of Amiodarone toxicity.

2. When teaching a client about a new prescription for Celecoxib, which of the following information should the nurse include?

• A. Increases the risk for a myocardial infarction
• B. Decreases the risk of stroke
• C. Inhibits COX-1
• D. Increases platelet aggregation

Correct answer: A

Rationale: The nurse should educate the client that taking Celecoxib increases the risk of a myocardial infarction due to its suppression of vasodilation. Celecoxib belongs to the class of NSAIDs known to have cardiovascular risks, including an increased risk of heart attacks. Choice B is incorrect because Celecoxib does not decrease the risk of stroke. Choice C is incorrect because Celecoxib selectively inhibits COX-2 rather than COX-1. Choice D is incorrect because Celecoxib does not increase platelet aggregation; in fact, it inhibits platelet aggregation.

3. Which of the following is not a side effect of the ACE Inhibitor (Captopril)?

• A. Rash
• B. Angioedema
• C. Cough
• D. Congestion

Correct answer: D

Rationale: Congestion is not a common side effect associated with ACE inhibitors such as Captopril. ACE inhibitors are known to cause a dry, persistent cough due to bradykinin accumulation, rash, and angioedema, but congestion is not typically listed as a side effect.

4. A provider prescribes phenobarbital for a client who has a seizure disorder. The medication has a long half-life of 4 days. How many times per day should the nurse expect to administer this medication?

• A. One
• B. Two
• C. Three
• D. Four

Correct answer: A

Rationale: Phenobarbital, with a long half-life of 4 days, remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should administer phenobarbital once a day to maintain a consistent therapeutic effect without the need for multiple daily doses. Administering the medication more than once a day would not be necessary and could increase the risk of side effects or toxicity. Therefore, the correct answer is to administer phenobarbital once a day.

5. Which of the following is the antidote for lead poisoning?

• A. Naloxone
• B. Nitrite
• C. CaEDTA
• D. Dialysis

Correct answer: C

Rationale: Calcium disodium ethylenediaminetetraacetic acid (CaEDTA) is the antidote for lead poisoning. CaEDTA works by chelating lead, forming a complex that is then excreted in the urine. It is used in chelation therapy to treat lead poisoning by reducing lead levels in the body.
