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. Hydrochlorothiazide is classified as a
- A. Anti-inflammatory
- B. Antiarrhythmic
- C. Diuretic
- D. Antifungal
Correct answer: C
Rationale: Hydrochlorothiazide is classified as a diuretic. Diuretics are medications that help the body get rid of excess salt and water by increasing urine production, reducing fluid retention, and lowering blood pressure. Option A, Anti-inflammatory, is incorrect because hydrochlorothiazide does not primarily reduce inflammation. Option B, Antiarrhythmic, is incorrect because hydrochlorothiazide is not used to correct heart rhythm irregularities. Option D, Antifungal, is incorrect because hydrochlorothiazide is not used to treat fungal infections.
3. A client's plasma Lithium level is 2.1 mEq/L. Which of the following is an appropriate action by the nurse?
- A. Perform immediate gastric lavage.
- B. Prepare the client for hemodialysis.
- C. Administer an additional oral dose of lithium.
- D. Request a stat repeat of the laboratory test.
Correct answer: A
Rationale: In a client with a plasma lithium level of 2.1 mEq/L, immediate gastric lavage is appropriate for severe toxicity. Gastric lavage can help lower the client's lithium level by removing the unabsorbed lithium from the stomach.
4. A client with Schizophrenia is taking Risperidone. Which of the following instructions should the nurse include in the teaching?
- A. Increase your intake of snacks to prevent weight loss.
- B. Notify the provider if you develop breast enlargement.
- C. Be aware of the possibility of mild seizures while taking this medication.
- D. Expect an increase in libido when taking this medication.
Correct answer: B
Rationale: The correct instruction the nurse should provide to the client taking Risperidone for Schizophrenia is to notify the provider if they develop breast enlargement. Risperidone can lead to an increase in prolactin levels, causing gynecomastia (breast enlargement) and galactorrhea. Therefore, it is crucial for the client to report these manifestations to the healthcare provider for appropriate management. Choices A, C, and D are incorrect. Increasing snack intake to prevent weight loss is not a specific concern related to Risperidone. Mild seizures are not a common side effect of Risperidone, so this instruction is unnecessary. Risperidone is more likely to cause sexual side effects like decreased libido rather than an increase.
5. Which drug class has been found to decrease mortality if given within 8 hours of an MI due to a decrease in cardiac workload?
- A. Antiplatelets
- B. Beta-adrenergic blockers
- C. ACE inhibitors
- D. Calcium channel blockers
Correct answer: B
Rationale: Beta-adrenergic blockers have been shown to decrease mortality when administered within 8 hours of a myocardial infarction (MI). They do so by reducing cardiac workload, which helps improve outcomes post-MI. These drugs work by blocking the effects of adrenaline on the heart, leading to decreased heart rate, blood pressure, and myocardial oxygen demand, thereby protecting the heart muscle from further damage. This makes them a crucial part of the treatment regimen for acute coronary syndromes like MI.
