ATI Capstone Pharmacology Assessment 1
1. A nurse is caring for a client prescribed ferrous sulfate for the treatment of anemia. Which of the following instructions should be included in client teaching about this medication?
- A. Take the medication on an empty stomach to maximize absorption
- B. Notify your provider if your stool becomes dark green
- C. Decrease dietary fiber intake while taking this medication
- D. Take prescribed antacids at the same time as this medication
Correct answer: A
Rationale: The correct answer is A. The nurse should instruct clients to take iron on an empty stomach, 1 hour before meals to maximize absorption. This enhances the medication's effectiveness. Option B is incorrect because dark green stool is a common side effect of iron supplements and does not necessarily indicate a problem. Option C is incorrect as dietary fiber intake does not need to be decreased while taking iron supplements. Option D is incorrect because antacids can interfere with the absorption of iron and should not be taken at the same time.
2. A client with an artificial heart valve is prescribed warfarin therapy. Which of the following laboratory values should the nurse monitor to assess the therapeutic effect of warfarin?
- A. Hemoglobin (Hgb)
- B. Prothrombin time (PT)
- C. Bleeding time
- D. Activated partial thromboplastin time (aPTT)
Correct answer: B
Rationale: The correct answer is B: Prothrombin time (PT). Warfarin is an anticoagulant medication that works by inhibiting the clotting factors dependent on vitamin K, such as factors II, VII, IX, and X. The prothrombin time (PT) measures the extrinsic pathway and is used to monitor the therapeutic effects of warfarin therapy. Monitoring PT helps assess the time it takes for the blood to clot, ensuring that the anticoagulant effect is within the desired range. Choices A, C, and D are incorrect because hemoglobin (Hgb) measures the amount of hemoglobin in the blood, bleeding time assesses the time it takes for bleeding to stop, and activated partial thromboplastin time (aPTT) is used to monitor heparin therapy, not warfarin therapy.
3. A nurse is caring for a client newly prescribed doxazosin mesylate. Which of the following instructions should the nurse include in client education regarding taking the first dose of this medication?
- A. Change positions slowly and lie down if dizziness occurs
- B. There is no need to avoid normal activities
- C. Avoid dairy products while taking this medication
- D. Do not eat green leafy vegetables
Correct answer: A
Rationale: Corrected Rationale: First-dose orthostatic hypotension can occur with doxazosin. The nurse should advise the client to change positions slowly and lie down if dizziness occurs. Choice B is incorrect because it does not address the potential side effect of dizziness. Choice C and D are also incorrect as there is no specific dietary restriction related to doxazosin mesylate.
4. A nurse is caring for a client who is prescribed warfarin. Which of the following laboratory tests should the nurse review to evaluate the therapeutic effect of this medication?
- A. aPTT
- B. INR
- C. Serum glucose
- D. Bilirubin
Correct answer: B
Rationale: The correct answer is B: INR. The International Normalized Ratio (INR) is the most reliable test for evaluating the therapeutic effects of warfarin therapy. INR measures the clotting ability of the blood and helps determine if the dosage of warfarin is within the therapeutic range. Choice A, aPTT, is not typically used to monitor the effects of warfarin. Choice C, Serum glucose, and choice D, Bilirubin, are not relevant to monitoring the therapeutic effect of warfarin.
5. A nurse has provided education to a client regarding prescribed levothyroxine sodium. Which of the following client statements demonstrates understanding of medication administration?
- A. I should take my medication as needed to alleviate symptoms
- B. I should take the medication in divided doses to ensure therapeutic drug levels
- C. I should take the medication in the morning to prevent insomnia
- D. I should take the medication on a full stomach
Correct answer: C
Rationale: Levothyroxine should be taken once in the morning to prevent insomnia and maintain therapeutic levels.
