A nurse is preparing to administer sulfadiazine 150mg/kg PO to divide equally every 6 hr to an adolescent who weighs 88 Ib.
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.).
1 tablet.
3 tablets.
4 tablets.
8 tablets.
The Correct Answer is B
Step 1: Convert weight from lb to kg.
88 lb ÷ 2.2 = 40 kg
Step 2: Calculate total daily dose in mg.
150 mg/kg × 40 kg = 6000 mg
Step 3: Calculate dose per administration (every 6 hr).
6000 mg ÷ 4 = 1500 mg
Step 4: Calculate number of tablets per dose.
1500 mg ÷ 500 mg/tab = 3 tablets
Answer:
3 tablets per dose.

Correct Answer is A
Explanation
Spironolactone is a potassium-sparing diuretic that can increase potassium levels in the blood.
It is important for clients taking spironolactone to limit their intake of potassium-rich foods to prevent hyperkalemia (high potassium levels).
Choice B is wrong because “I will take the medication on an empty stomach,” is not the correct answer because spironolactone can be taken with or without food.
Choice C is wrong because “I will use salt substitutes in place of table salt,” is not the correct answer because many salt substitutes contain potassium and can increase the risk of hyperkalemia.
Choice D is wrong because “I will double up on my medication if I miss a dose,” is not the correct answer because it is not recommended to double up on medication if a dose is missed.
Correct Answer is C
Explanation
Metformin is an antidiabetic agent used to treat type 2 diabetes mellitus.
It works by decreasing carbohydrate absorption from the gut, increasing glucose uptake in peripheral tissues in the presence of insulin, and reducing hepatic gluconeogenesis.
In normal patients, metformin ingestion is not associated with hypoglycemia.
However, it is still important to check the client’s glucose level to ensure that it is within a safe range.
Choice A is wrong because collecting the client’s uric acid level is not necessary after accidental administration of metformin.
Choice B is wrong because obtaining the client’s HDL level is not necessary after accidental administration of metformin.
Choice D is wrong because monitoring the client’s thyroid function levels is not necessary after accidental administration of metformin.
