A nurse is preparing to administer sucralfate 80 mg/kg/day to divide into four doses per day to a child who weighs 35 kg.

The amount available is sucralfate oral suspension 1 g/10 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) mL.

Answer and explanation.

The correct answer is choice B. To calculate the dose per mL, we need to use the following formula:

Dose per mL=Amount availableDose per kg×Weight Plugging in the given values, we get:

Dose per mL=1 g/10 mL80 mg/kg×35 kg

Simplifying the units and converting grams to milligrams, we get:

Dose per mL=1000 mg/10 mL2800 mg Dividing both sides by 10, we get:

Dose per mL=0.28 mL

Multiplying both sides by 4, we get the dose per day:

Dose per day=1.12 mL

Rounding to the nearest whole number, we get 1 mL as the answer.

Choice A is wrong because it uses 40 mg/kg instead of 80 mg/kg as the dose per kg.

Choice C is wrong because it uses 20 kg instead of 35 kg as the weight.

Choice D is wrong because.
