Question 1 of 5
A nurse is teaching a newly licensed nurse about administering naloxone to treat a client who is experiencing opioid toxicity. Which of the following information should the nurse include in the teaching?
Correct Answer: C
Rationale: The correct answer is C: Monitor the client for ventricular arrhythmia after administration. This is crucial because naloxone can precipitate ventricular arrhythmias in some cases due to its rapid reversal of opioid effects. Monitoring for this adverse effect allows for prompt intervention if needed.
Choice A is incorrect because naloxone is not administered orally, it is typically given intravenously or intramuscularly due to its rapid onset of action.
Choice B is incorrect as naloxone is not contraindicated for clients with glaucoma.
Choice D is incorrect because naloxone has a short duration of action, so it should be administered as needed rather than on a fixed schedule every 1 to 2 hours.
Question 2 of 5
A nurse is assessing a client who is taking combination oral contraceptives. Which of the following findings should the nurse report to the provider immediately?
Correct Answer: C
Rationale: The correct answer is C: Leg tenderness. This finding could indicate deep vein thrombosis (DVT), a serious side effect of oral contracepters. DVT can lead to life-threatening complications like pulmonary embolism. Cramps, abdominal bloating, and nausea are common side effects of oral contraceptives and not typically urgent. Leg tenderness is a red flag for DVT and requires immediate attention to prevent complications.
Question 3 of 5
A nurse is providing teaching to a client who has a new prescription for phenelzine. Which of the following foods should the nurse instruct the client to avoid?
Correct Answer: A
Rationale: The correct answer is A: Cheddar cheese. Phenelzine is a monoamine oxidase inhibitor (MAOI) that interacts with tyramine-rich foods, such as aged cheeses like cheddar. Tyramine can cause dangerously high blood pressure levels when combined with MAOIs. Sweet potatoes, orange juice, and canned tuna do not contain high levels of tyramine and are safe to consume with phenelzine.
Question 4 of 5
A nurse is caring for a client who has a life-threatening ventricular dysrhythmia. Which of the following medications should the nurse anticipate administering?
Correct Answer: D
Rationale: The correct answer is D: Amiodarone. Amiodarone is an antiarrhythmic medication commonly used to treat life-threatening ventricular dysrhythmias. It works by prolonging the action potential duration and refractory period of cardiac muscle cells, thereby stabilizing the heart's electrical activity. Digoxin (
A) is not typically used for ventricular dysrhythmias. Dopamine (
B) is a vasopressor used for hypotension, not dysrhythmias. Verapamil (
C) is a calcium channel blocker, which is contraindicated in ventricular dysrhythmias.
Therefore, the nurse should anticipate administering amiodarone to treat the client's life-threatening ventricular dysrhythmia.
Question 5 of 5
A nurse is preparing to administer dextrose 5% in water 500 mL over 12 hr to a client. The nurse should set the IV pump to deliver how many mL/hr?
Correct Answer: A
Rationale: The correct answer is A: 42 mL/hr.
To calculate the IV pump rate, divide the total volume to be infused by the total time in hours (500 mL ÷ 12 hr = 41.67, rounded to 42 mL/hr). This ensures a consistent and accurate delivery of dextrose over the prescribed duration.
Choices B, C, and D are incorrect as they do not result from the correct calculation. It's important to calculate the IV pump rate precisely to prevent under or over-infusion, which can lead to potential harm to the client.
