A nurse is preparing to administer furosemide 1 mg/kg IV bolus to a preschooler who weighs 36 lb. Available is furosemide injection 10 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if applicable. Do not use a trailing zero.)
The Correct Answer is ["1.6"]
To calculate this, first convert the preschooler's weight from pounds to kilograms: 36 lb * (1 kg / 2.2 lb) = 16.36 kg.
Then, calculate the dose of furosemide in mg: 1 mg/kg * 16.36 kg = 16.36 mg.
Finally, divide the dose in mg by the concentration of the furosemide injection to find the volume to administer: 16.36 mg / (10 mg/mL) = 1.636 mL/dose, which rounds to 1.6 mL when rounded to the nearest tenth.

Correct Answer is ["0.2 mL"]
Explanation
To find out how many mL of enoxaparin the nurse should administer, we need to set up a proportion. If 30 mg of enoxaparin is equivalent to 0.3 mL, then 20 mg of enoxaparin is equivalent to x mL.
The proportion can be writen as 30/0.3 = 20/x. Solving for x, we get x = (20 * 0.3) / 30 = 0.2 mL.
Correct Answer is ["0.9 mL"]
Explanation
To find out how many mL of gentamicin the nurse should administer, we need to set up a proportion. If 40 mg of gentamicin is equivalent to 1 mL, then 36 mg of gentamicin is equivalent to x mL.
The proportion can be writen as 40/1 = 36/x. Solving for x, we get x = (36 * 1) / 40 = 0.9 mL.
The answer is rounded to the nearest tenth as instructed.
