ATI Pharmacology Proctored Exam 2023
1. A client with Angina Pectoris asks the nurse about the next step if they take one tablet, wait 5 minutes, but still have Anginal pain. Which response should the nurse provide?
- A. Take two more sublingual tablets at the same time.
- B. Call emergency services.
- C. Take a sustained-release nitroglycerin capsule.
- D. Wait another 5 minutes then take a second sublingual tablet.
Correct answer: B
Rationale: If anginal pain persists after taking the first tablet and waiting 5 minutes, the priority step is to call emergency services (911) and then take a second sublingual tablet. Persistent pain could indicate a myocardial infarction, and immediate medical attention is crucial. Taking two more tablets at the same time (Choice A) can lead to excessive vasodilation and hypotension. Taking a sustained-release nitroglycerin capsule (Choice C) is not appropriate for immediate relief during an acute episode. Waiting another 5 minutes and then taking a second tablet (Choice D) is not advisable in this emergency situation where prompt action is necessary.
2. When administering medications to a 4-month-old infant, which of the following pharmacokinetic principles should be considered? (Select all that apply.)
- A. Infants have a more rapid gastric emptying time.
- B. Infants have immature liver function.
- C. Infants' blood-brain barrier is poorly developed.
- D. Infants have an increased ability to absorb topical medications.
Correct answer: B
Rationale: When administering medications to a 4-month-old infant, the pharmacokinetic principle to consider is that infants have immature liver function until 1 year of age. This requires medications metabolized by the liver to be administered in smaller dosages. While infants do have a more rapid gastric emptying time, immature liver function is a more critical pharmacokinetic consideration in this context. Additionally, although infants have a poorly developed blood-brain barrier, this relates more to pharmacodynamic effects rather than pharmacokinetic principles. The statement about infants having an increased ability to absorb topical medications is not directly related to pharmacokinetic principles, making choice B the correct answer.
3. A client is starting therapy with Metformin. Which of the following instructions should the nurse include?
- A. Take this medication with your first bite of food.
- B. Take this medication on an empty stomach.
- C. Take this medication before bedtime.
- D. Take this medication every other day.
Correct answer: A
Rationale: Metformin should be taken with meals to reduce gastrointestinal side effects and ensure better absorption. Instructing the client to take the medication with the first bite of food helps in achieving optimal effectiveness and minimizes the risk of side effects like nausea or upset stomach. Choice B is incorrect because taking Metformin on an empty stomach can lead to increased gastrointestinal side effects. Choice C is incorrect as there is no specific timing requirement for taking Metformin before bedtime. Choice D is incorrect as Metformin is usually taken daily, not every other day.
4. When a client has a new prescription for Warfarin, which of the following foods should they avoid based on the nurse's instructions?
- A. Broccoli
- B. Bananas
- C. Chicken
- D. Potatoes
Correct answer: A
Rationale: Clients prescribed Warfarin should avoid foods high in vitamin K, like broccoli, as they can counteract the medication's effectiveness. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming high vitamin K foods can interfere with its anticoagulant effects. Bananas, chicken, and potatoes are not high in vitamin K and do not have a significant impact on Warfarin therapy.
5. A client reports taking Aspirin about four times daily for a sprained wrist. Which of the following prescribed medications taken by the client is contraindicated with aspirin?
- A. Digoxin
- B. Metformin
- C. Warfarin
- D. Nitroglycerin
Correct answer: C
Rationale: The correct answer is C, Warfarin. Aspirin increases the effect of anticoagulants like warfarin by inhibiting platelet aggregation, leading to an increased risk of bleeding. Therefore, the use of aspirin is generally contraindicated for clients taking warfarin. Choices A, B, and D are not contraindicated with aspirin. Digoxin, Metformin, and Nitroglycerin do not have significant interactions with Aspirin, unlike Warfarin, making them safe to use concomitantly.
