Question 1 of 5
A c+2:34lient has a medical prescription for nifedipine [Adalat XL]. Which of the following should the nurse teach the client about this medication?
Correct Answer: A
Rationale:
Correct
Answer: A
Rationale:
1. Nifedipine [Adalat XL] is an extended-release medication designed to release the drug slowly over time.
2. Cutting, crushing, or chewing the medication can disrupt the extended-release mechanism, leading to a sudden release of the drug and potential adverse effects.
3. By swallowing the medication whole, the client ensures the drug is released gradually, maintaining its therapeutic effect.
Summary:
B: Taking blood pressure in the morning is not directly related to the administration of nifedipine.
C: Caution with OTC cold medications is a general precaution and not specific to nifedipine.
D: Taking the medication before bedtime is not specified for nifedipine and may not align with its dosing schedule.
Question 2 of 5
A client has been diagnosed with a life-threatening recurrent ventricular fibrillation that has not responded to other medications or defibrillation. Which of the following does the nurse anticipate will be prescribed next?
Correct Answer: D
Rationale: The correct answer is D: Amiodarone. This medication is used to treat life-threatening ventricular arrhythmias like ventricular fibrillation that have not responded to other treatments. Amiodarone works by prolonging the action potential and refractory period of cardiac tissue, helping to stabilize the heart's rhythm. Quinidine (
A) is not typically used for ventricular arrhythmias. Digoxin (
B) is used for heart failure and atrial fibrillation, not ventricular fibrillation. Atropine (
C) is used for bradycardia, not ventricular fibrillation. Amiodarone is the drug of choice for this situation.
Question 3 of 5
Which of the following will the nurse include in teaching for a client taking ferrous sulfate [Feosol]?
Correct Answer: A
Rationale: The correct answer is A because ferrous sulfate can stain teeth and cause GI upset. Diluting the liquid with juice or water and using a straw can help minimize these side effects.
Choice B is incorrect because dairy products can decrease iron absorption.
Choice C is incorrect because green or brown stools are normal with iron therapy.
Choice D is incorrect because citrus juices can enhance iron absorption.
Question 4 of 5
The nurse is assessing a client on a telemetry unit when the client states, "My vision is blurry, and I have been seeing yellow/green halos everywhere I look." Which of the following would the nurse suspect?
Correct Answer: D
Rationale: The correct answer is D: Digoxin (Lanoxin) toxicity. Blurred vision and seeing yellow/green halos are classic signs of digoxin toxicity. Digoxin can cause visual disturbances due to its effects on the optic nerve. Hyperglycemia (choice
A) typically does not present with visual disturbances. Captopril (choice
B) and Verapamil (choice
C) do not typically cause visual changes like halos. Digoxin toxicity (choice
D) is the most likely cause based on the client's symptoms.
Question 5 of 5
A client prescribed fluoxetine (Prozac) returns to the clinic one week after beginning therapy and states, "This drug is not working, I am still very sad." Which of the following would be the nurse's best response?
Correct Answer: D
Rationale: The correct answer is D: "This drug could take 4-6 weeks to begin working." This response is correct because fluoxetine, a selective serotonin reuptake inhibitor (SSRI), typically takes around 4-6 weeks to reach its full therapeutic effect. It is important for the nurse to educate the client on the delayed onset of action to manage expectations effectively.
Choice A is incorrect as adding another drug without giving fluoxetine an adequate trial period may not be necessary and could increase the risk of side effects.
Choice B is incorrect because while fluoxetine may start to show some effects within 1-3 weeks, the full therapeutic effect is generally achieved after 4-6 weeks.
Choice C is incorrect as switching to a different antidepressant prematurely may not be beneficial without giving fluoxetine sufficient time to work.
