A nurse is preparing to administer morphine 0.1 mg/kg IM to a school-age child who weighs 88 Ib. The amount available is morphine 4 mg/mL. How many ml should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1"]

Step-by-Step Solution:

Convert the child's weight from pounds to kilograms.

1 pound is approximately 0.453592 kilograms.

88 pounds = 88 x 0.453592 = 39.916736 kilograms.

Calculate the total dose of morphine.

The prescribed dose is 0.1 mg/kg.

The child weighs 39.916736 kg.

Total dose = 0.1 mg/kg x 39.916736 kg = 3.9916736 mg.

Calculate the volume of morphine injection to administer.

The available morphine injection is 4 mg/mL.

To find the volume, we can set up a proportion:

4 mg / 1 mL = 3.9916736 mg / x mL

Cross-multiplying:

4x = 3.9916736

Solving for x:

x = 3.9916736 / 4 = 0.9979184 mL

Round the answer to the nearest whole number: 1 mL

Correct Answer is ["0.3"]

Explanation

Given:

Desired dose: Penicillin G benzathine 200,000 units IM

Available concentration: Penicillin G benzathine injection 600,000 units/mL

To find:

Volume to administer (in mL)

Step 1: Set up the proportion

We can use the following proportion to solve the problem:

(Desired dose) / (Available concentration) = Volume to administer

Step 2: Substitute the values

Plugging in the given values, we get:

(200,000 units) / (600,000 units/mL) = Volume to administer

Step 3: Simplify

To simplify, we can invert the denominator and multiply:

(200,000 units) * (1 mL / 600,000 units) = Volume to administer

The "units" cancel out, leaving us with:

(200,000 * 1 mL) / 600,000 = Volume to administer

Step 4: Calculate

Performing the multiplication and division, we get:

200,000 mL / 600,000 = Volume to administer

0.33 mL = Volume to administer

Step 5: Round to the nearest whole number

Since the question asks for the volume rounded to the nearest whole number, we round 0.3.

Correct Answer is ["7.5"]

Explanation

Identify the given information:

Volume of fluconazole oral suspension: 1.5 tsp

Use the conversion factor:

1 tsp = 5 mL

Set up the conversion:

1.5 tsp x (5mL / 1 tsp)

Calculate the result:

1.5 tsp x 5mL/tsp = 7.5 mL

Round the answer to the nearest tenth: 7.5 mL
