ATI Pharmacology Quizlet
1. A client has a new prescription for Levothyroxine. Which of the following instructions should the nurse include?
- A. Take this medication with food.
- B. Take this medication at bedtime.
- C. Take this medication on an empty stomach.
- D. Take this medication with antacids.
Correct answer: C
Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption, affecting the medication's effectiveness.
2. A client has a new prescription for Clonidine. What instruction should the nurse include during teaching?
- A. Take the medication with food.
- B. Expect to feel drowsy or lightheaded.
- C. Increase your fluid intake.
- D. Avoid foods high in fat.
Correct answer: B
Rationale: The correct instruction when teaching a client about Clonidine is to expect to feel drowsy or lightheaded. Clonidine can cause these side effects, especially when starting the medication. The nurse should advise the client to avoid activities that require alertness until they understand how the medication affects them. Choices A, C, and D are incorrect because taking Clonidine with food, increasing fluid intake, or avoiding foods high in fat are not specific instructions related to managing the side effects of Clonidine.
3. A client has a new prescription for Cyanocobalamin (Vitamin B12) injections. Which of the following client statements indicates an understanding of the teaching?
- A. I will need to take this medication for the rest of my life.
- B. I will stop taking the medication when my symptoms improve.
- C. I should take this medication with food.
- D. I will need to avoid green, leafy vegetables while taking this medication.
Correct answer: A
Rationale: The correct answer is A. Clients with pernicious anemia or other causes of vitamin B12 deficiency may need to take cyanocobalamin for life to prevent deficiency. It is a lifelong treatment in many cases to maintain adequate B12 levels. Choice B is incorrect because stopping the medication when symptoms improve may lead to a relapse of the deficiency. Choice C is incorrect as cyanocobalamin injections are usually administered on an empty stomach. Choice D is incorrect as there is no need to avoid green, leafy vegetables while taking cyanocobalamin; in fact, these vegetables are good dietary sources of vitamin B12.
4. A client has a new prescription for Warfarin. The nurse should identify that the concurrent use of which of the following medications increases the client's risk of bleeding?
- A. Vitamin K
- B. Calcium carbonate
- C. Acetaminophen
- D. Ranitidine
Correct answer: C
Rationale: The correct answer is Acetaminophen (Choice C). Acetaminophen, especially in high doses, can increase the risk of bleeding in clients taking Warfarin. It can potentiate the anticoagulant effect of Warfarin, leading to an increased risk of bleeding. Vitamin K (Choice A) is actually used to reverse the effects of Warfarin in case of over-anticoagulation, so it does not increase the risk of bleeding. Calcium carbonate (Choice B) and Ranitidine (Choice D) do not significantly interact with Warfarin to increase the risk of bleeding.
5. Which of the following is classified as a class IA Sodium Channel blocker?
- A. Quinidine
- B. Disopyramide
- C. Aminodarone
- D. Propafenone
Correct answer: A
Rationale: Quinidine is classified as a class IA sodium channel blocker. Class IA antiarrhythmics, like quinidine, work by blocking sodium channels and delaying repolarization. Propafenone, mentioned in the original rationale, is actually a class IC antiarrhythmic agent, not a class IA sodium channel blocker.
