ATI Capstone Pharmacology Assessment 1
1. A client is prescribed digoxin 0.125 mg daily for heart failure. Which of the following client reports should concern the nurse as a sign of digoxin toxicity?
- A. Increased appetite
- B. Visual disturbances
- C. Weight gain
- D. Constipation
Correct answer: B
Rationale: Visual disturbances such as blurred vision or seeing halos around lights are common signs of digoxin toxicity. Increased appetite, weight gain, and constipation are not typically associated with digoxin toxicity. Weight gain could be a sign of worsening heart failure rather than digoxin toxicity. Increased appetite and constipation are not specific signs of digoxin toxicity and are less likely to be related.
2. A client is receiving a dopamine infusion via a peripheral IV. Which of the following actions should the nurse take if the IV site appears infiltrated?
- A. Slow the infusion and continue to monitor the site
- B. Stop the infusion
- C. Apply a warm compress to the site
- D. Apply a cold compress to the site
Correct answer: B
Rationale: When an IV site appears infiltrated, it indicates that the medication is leaking into the surrounding tissues. In such a situation, the infusion should be stopped immediately to prevent further tissue damage. Choice A is incorrect because slowing the infusion would still allow the medication to leak into the tissues. Choices C and D are also incorrect as applying compresses can exacerbate the tissue damage caused by infiltration.
3. 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.
4. A nurse is caring for a client with diabetes and a new prescription for 14 units of regular insulin and 28 units of NPH insulin subcutaneously at breakfast daily. What is the total number of units of insulin that the nurse should prepare in the insulin syringe?
- A. 14 units
- B. 28 units
- C. 32 units
- D. 42 units
Correct answer: D
Rationale: The nurse should combine both orders of insulin in the same syringe. To prepare the correct dose, the nurse should withdraw the regular insulin first (14 units) and then the NPH insulin (28 units), totaling 42 units. This combination ensures the client receives the prescribed doses of both types of insulin. Choices A, B, and C are incorrect because the nurse needs to prepare and administer both types of insulin as prescribed, resulting in a total of 42 units in the syringe.
5. A client is prescribed HMG CoA reductase inhibitor, atorvastatin. Which of the following should be monitored while this medication is prescribed?
- A. Liver function tests
- B. Renal function tests
- C. Visual acuity screening
- D. Hearing screenings
Correct answer: A
Rationale: The correct answer is A: Liver function tests. Atorvastatin, an HMG CoA reductase inhibitor, can lead to hepatotoxicity, making it essential to monitor liver function tests regularly. Choices B, C, and D are incorrect because atorvastatin primarily affects the liver, not the kidneys, vision, or hearing.
