1. A 55-year-old client has levothyroxine ordered. Which of the below past medical history concerns may contraindicate with her medication management of hypothyroidism?

Correct answer: B

Rationale: The correct answer is B: Osteoporosis. Osteoporosis is a concern with levothyroxine as it can increase the risk for fractures, particularly in older adults. Levothyroxine treatment can exacerbate bone loss in individuals with osteoporosis. Choices A, C, and D are not directly contraindicated with levothyroxine therapy for hypothyroidism.

2. A nurse has provided education to a client regarding prescribed levothyroxine sodium. Which of the following client statements demonstrates understanding of medication administration?

Correct answer: C

Rationale: Levothyroxine should be taken once in the morning to prevent insomnia and maintain therapeutic levels.

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?

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 client receiving epoetin alfa therapy for anemia is being monitored for therapeutic effects. Which of the following laboratory values indicates the medication is effective?

Correct answer: B

Rationale: The correct answer is B: Hematocrit. An increase in hematocrit levels indicates the effectiveness of epoetin alfa in treating anemia. Hematocrit reflects the percentage of red blood cells in the blood, so an increase in hematocrit signifies an improvement in the patient's red blood cell count and oxygen-carrying capacity. Choices A, C, and D are incorrect because white blood cell count, platelet count, and red blood cell count do not directly reflect the therapeutic effects of epoetin alfa in treating anemia.

5. A nurse is caring for a client with hypothyroidism. Which of the following findings indicates that the client is experiencing an adverse effect from the prescribed levothyroxine?

Correct answer: A

Rationale: Tachycardia is the correct answer as it is an adverse effect of levothyroxine. Levothyroxine is a medication used to treat hypothyroidism by supplementing the body with thyroid hormone. Tachycardia, or a fast heart rate, can indicate an overdosage or increased sensitivity to levothyroxine. Bradycardia, slow heart rate, weight loss, and increased appetite are not typically associated with adverse effects of levothyroxine. Bradycardia may actually be a symptom of untreated hypothyroidism.
