ATI Pharmacology Proctored Exam
1. A healthcare provider is providing discharge instructions to a client who has a new prescription for Warfarin. Which of the following foods should the provider instruct the client to avoid?
- A. Broccoli
- B. Bananas
- C. Chicken
- D. Potatoes
Correct answer: A
Rationale: Clients taking Warfarin should avoid foods high in vitamin K, such as broccoli, as they can interfere with the effectiveness of the medication. Vitamin K can counteract the anticoagulant effects of Warfarin, potentially leading to blood clotting issues. Broccoli is rich in vitamin K, so its consumption should be consistent to avoid fluctuations in the medication's effectiveness. Bananas, chicken, and potatoes are not known to significantly interact with Warfarin and do not pose a risk of affecting its anticoagulant properties.
2. A client has a new prescription for Clonidine. Which of the following adverse effects should the nurse monitor?
- A. Drowsiness
- B. Dry mouth
- C. Weight gain
- D. Insomnia
Correct answer: B
Rationale: Dry mouth is a common adverse effect of Clonidine. Clonidine can reduce saliva production, leading to dry mouth. To alleviate this symptom, the client should be advised to increase fluid intake or use sugar-free gum or candy. Monitoring for dry mouth is important to prevent complications such as oral health issues. Drowsiness, weight gain, and insomnia are potential side effects of Clonidine but are less common compared to dry mouth. Therefore, the nurse should prioritize monitoring for dry mouth as it's a more prevalent adverse effect associated with this medication.
3. A client with thrombophlebitis receiving heparin by continuous IV infusion asks the nurse how long it will take for the heparin to dissolve the clot. Which of the following responses should the nurse give?
- A. It usually takes heparin at least 2 to 3 days to reach a therapeutic blood level.
- B. A pharmacist is the person to answer that question.
- C. Heparin does not dissolve clots. It stops new clots from forming.
- D. The oral medication you will take after this IV will dissolve the clot.
Correct answer: C
Rationale: The correct response is C. Heparin does not dissolve clots; it prevents new clots from forming. Heparin works by inhibiting the formation of new clots and the extension of existing clots, rather than directly dissolving them. The client should be informed that the purpose of heparin therapy is to prevent the clot from getting larger and to reduce the risk of new clots forming. Choices A, B, and D are incorrect. Choice A talks about reaching a therapeutic blood level of heparin, which is not related to clot dissolution. Choice B deflects the question to a pharmacist without providing relevant information. Choice D inaccurately suggests that an oral medication will dissolve the clot, which is not the mechanism of action for heparin.
4. What is the expected pharmacological action of propranolol?
- A. Block stimulation of beta1 receptors
- B. Alter water and electrolyte transport in the large intestine
- C. Block stimulation of beta2 receptors
- D. Both A and C are correct
Correct answer: D
Rationale: Propranolol exerts its pharmacological action by blocking stimulation of both beta1 and beta2 receptors. By doing so, it leads to decreased heart rate and blood pressure. Therefore, both options A and C are correct as propranolol affects both types of beta receptors. Choice B is incorrect as propranolol does not alter water and electrolyte transport in the large intestine.
5. What is a common side effect that typically occurs with the initial therapy of Nitroglycerine as a result of increased vasodilation?
- A. Abdominal cramps
- B. Calf pain
- C. Headache
- D. Blurred vision
Correct answer: C
Rationale: Headache is a common side effect associated with the initial therapy of Nitroglycerine due to its vasodilatory properties. The vasodilation caused by Nitroglycerine leads to relaxation of blood vessels, including those in the head, which can result in headaches. This side effect is considered normal and is often transient, diminishing with continued use of the medication.
