Question 1 of 5
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?
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.
Question 2 of 5
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?
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.
Question 3 of 5
A nurse is caring for a client prescribed methotrexate for rheumatoid arthritis. Which of the following client history findings requires the nurse to question the administration of this medication?
Correct Answer: C
Rationale: The correct answer is C: Peptic ulcer disease. Methotrexate can exacerbate peptic ulcer disease, leading to serious complications. This finding warrants questioning the administration of methotrexate to prevent harm to the client. Choices A, B, and D are not directly contraindicated with methotrexate use. Osteoporosis, hypertension, and immunosuppression are not typically reasons to question the administration of methotrexate for rheumatoid arthritis.
Question 4 of 5
A nurse is caring for a client taking ciprofloxacin for an infection. Which of the following adverse effects should the nurse include in the client education?
Correct Answer: B
Rationale: The correct answer is B: Tendon rupture. Ciprofloxacin belongs to the fluoroquinolone class of antibiotics, which is associated with the adverse effect of tendon rupture. Tendon rupture is a severe but rare side effect that can occur with the use of ciprofloxacin. Educating the client about this potential adverse effect is crucial to promote awareness and early recognition of symptoms, such as tendon pain, swelling, or inflammation. Choices A, C, and D are not typically associated with ciprofloxacin use and are less relevant for client education in this scenario.
Question 5 of 5
A healthcare provider is preparing to administer heparin sodium to a client with deep vein thrombosis (DVT). Which of the following laboratory values should the provider monitor during therapy?
Correct Answer: C
Rationale: The correct answer is C: aPTT. The healthcare provider should monitor the activated partial thromboplastin time (aPTT) value during heparin therapy to assess the client's coagulation status. Heparin affects the intrinsic pathway of the coagulation cascade, and monitoring aPTT helps ensure that the client is within the therapeutic range to prevent bleeding or clotting issues. INR (Choice A) is used to monitor warfarin therapy, not heparin. Serum creatinine (Choice B) is not directly related to monitoring heparin therapy. Bilirubin (Choice D) is related to liver function, not heparin therapy.
