ATI Pharmacology Proctored Exam
1. A client is receiving long-term aspirin therapy. The healthcare provider should monitor the client for which of the following complications?
- A. Hemorrhagic stroke
- B. Thromboembolic stroke
- C. Iron deficiency anemia
- D. Neutropenia
Correct answer: A
Rationale: The correct answer is A: Hemorrhagic stroke. Long-term aspirin therapy can lead to hemorrhagic stroke due to its antiplatelet effects, which increase the risk of bleeding. Aspirin inhibits platelet aggregation, which can predispose the individual to bleeding complications, including hemorrhagic stroke. Choices B, C, and D are incorrect because aspirin therapy is more likely to cause bleeding complications rather than thromboembolic events, iron deficiency anemia, or neutropenia.
2. A client has a new prescription for Pancrelipase for chronic pancreatitis. Which of the following instructions should be included by the nurse?
- A. Take the medication with meals and snacks.
- B. Chew the tablet thoroughly before swallowing.
- C. Take the medication 1 hour before meals.
- D. Expect the stool to be yellow.
Correct answer: A
Rationale: The correct instruction for taking Pancrelipase is to take it with meals and snacks to aid in the digestion of fats, proteins, and carbohydrates. This helps optimize the effectiveness of the medication in managing chronic pancreatitis. Choice B is incorrect because Pancrelipase should not be chewed but swallowed whole. Choice C is incorrect as the medication should be taken with meals. Choice D is incorrect because while Pancrelipase can cause stool changes, yellow stool is not an expected outcome.
3. What is the antidote for Heparin?
- A. Protamine sulfate
- B. Vitamin K
- C. Naloxone
- D. Toradol
Correct answer: A
Rationale: The correct answer is A: Protamine sulfate. Heparin is an anticoagulant that prevents blood clotting. Protamine sulfate is the antidote for Heparin as it binds to heparin, neutralizing its anticoagulant effects. Vitamin K is not the antidote for Heparin; it is used to reverse the effects of warfarin, another anticoagulant. Naloxone is an opioid antagonist for opioids, and Toradol is a nonsteroidal anti-inflammatory drug (NSAID) for pain relief. Therefore, the correct antidote for Heparin is Protamine sulfate.
4. The healthcare professional is preparing to administer atenolol (Tenormin) to a client with angina. Which vital sign would cause the healthcare professional to question administering this drug?
- A. Respirations 12 breaths per minute
- B. Pulse 52 beats per minute
- C. Blood pressure 134/72
- D. Oxygen saturation 95%
Correct answer: B
Rationale: Atenolol is a beta-blocker medication that can lower heart rate. A pulse of 52 beats per minute is relatively low and administering atenolol could further decrease the heart rate, potentially leading to bradycardia. Monitoring the pulse rate and holding the medication if the pulse is below the prescribed parameters is crucial to prevent adverse effects such as bradycardia and hypotension.
5. 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. Acetaminophen, especially in high doses, can increase the risk of bleeding in clients taking warfarin. Warfarin works by inhibiting the clotting factors dependent on vitamin K, so Vitamin K intake should be consistent but not excessive. Calcium carbonate and ranitidine do not significantly increase the risk of bleeding when used concurrently with Warfarin.
