Question 4 of 5
A client who has Graves' disease is prescribed methimazole. Which of the following effects should the nurse expect to see after the client has taken the medication for 2 months?

Question 5 of 5
A nurse is preparing to administer sulfadiazine 150mg/kg PO to divide equally every 6 hr to an adolescent who weighs 88 lb. Available is sulfadiazine 500 mg/tab. How many tablets should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale: 88 lb ÷ 2.2 = 40 kg; 150 mg/kg × 40 kg = 6000 mg daily; 6000 mg ÷ 4 = 1500 mg per dose; 1500 mg ÷ 500 mg/tab = 3 tablets.
