A nurse is preparing to administer enoxaparin 20 mg subcutaneously to a school-age child. The amount available is enoxaparin 30 mg/0.3 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.2"]

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 ["1"]

Explanation

To find out how many tablespoons of magnesium hydroxide the nurse should administer, we need to convert the volume from mL to tablespoons.

There are approximately 14.7868 mL in 1 tablespoon.

Therefore, to convert 15 mL to tablespoons, we divide 15 by 14.7868.

This gives us approximately 1.014 tablespoons. The answer is rounded to the nearest whole number as instructed.

Correct Answer is ["1.2"]

Explanation

Step 1 is to convert the child’s weight from pounds to kilograms since the dosage of morphine is prescribed in mg/kg. We know that 1 kg is approximately equal to 2.2 lb. So, the child’s weight in kg is:

51 lb ÷ 2.2 = 23.18 kg

Step 2 is to calculate the total amount of morphine the child should receive per dose. The doctor ordered 0.1 mg of morphine per kg of body weight. So, the total amount of morphine per dose is:

0.1 mg/kg × 23.18 kg = 2.318 mg

Step 3 is to calculate the volume of morphine injection to be administered. We know that the available morphine injection has a concentration of 2 mg/mL. So, the volume in mL is:

2.318 mg ÷ (2 mg/mL) = 1.159 mL

Rounding this to the nearest tenth gives 1.2 mL. So, the nurse should administer 1.2 mL of morphine injection per dose.

So, the correct answer is 1.2 mL.
