A nurse is preparing to administer gentamicin to a child who weighs 44 lb. The provider prescribes 6 mg/kg/day IV to be administered in three equal doses. Available is gentamicin 40 mg/mL. How many mL should the nurse administer with each dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A rationale:

Rifampin does not typically cause insomnia.

Choice B rationale:

Rifampin can cause a red or orange discoloration of body fluids, including urine, not blue or green.

Choice C rationale:

It is recommended to take rifampin on an empty stomach, either 1 hour before or 2 hours after a meal.

Choice D rationale:

Unusual hair growth is not a known side effect of rifampin.

Choice A rationale:

While a tuberculin syringe can be used for insulin administration, it’s not necessary when mixing NPH and regular insulin. Insulin syringes are typically used for this purpose.

Choice B rationale:

Injecting air into each vial before withdrawing insulin helps equalize pressure and makes it easier to draw up the insulin. This should be done before withdrawing any insulin.

Choice C rationale:

Withdrawing NPH insulin first contradicts the standard practice of drawing up insulins. The usual recommendation is to draw up short-acting (regular) insulin before intermediate-acting (NPH) insulin.

Choice D rationale:

Shaking the regular insulin vial is unnecessary and could potentially create bubbles, making it harder to draw up the correct dose of insulin.
