Answer and Explanation

The Correct Answer is ["3"]

Calculating the Trimethoprim-Sulfamethoxazole Dose

Problem: Administer 120 mg of Bactrim-DS Oral Suspension. The available concentration is 200 mg/5 mL.

Steps:

Set up a proportion:

We want to find the number of milliliters (mL) needed.

We know the desired dose (120 mg) and the concentration of the medication (200 mg/5 mL).

Proportion:

x mL / 120 mg = 5 mL / 200 mg

Cross-multiply:

200x = 600

Solve for x:

x = 600 / 200

x = 3

Answer: The nurse should administer 3 mL of Bactrim-DS Oral Suspension per dose.

Correct Answer is ["33"]

Explanation

Step 1: Calculate the concentration of the medication:

Concentration (mg/mL) = Total Medication (mg) / Total Volume (mL)

Concentration = 2000 mg / 100 mL

Concentration = 20 mg/mL

Step 2: Calculate the infusion rate in mg/minute:

Infusion Rate (mg/minute) = Infusion Rate (mL/hour) x Concentration (mg/mL) x (1 hour / 60 minutes)

Infusion Rate = 100 mL/hour x 20 mg/mL x (1 hour / 60 minutes)

Infusion Rate = 33.33 mg/minute

Rounding to the nearest whole number, the client is receiving 33 mg of medication per minute.

Correct Answer is ["2"]

Explanation

To calculate the number of tablets needed, we can set up a proportion:

x tablets / 600 mcg = 1 tablet / 300 mcg

Cross-multiplying:

300x = 600

Solving for x:

x = 600 / 300

x = 2

Therefore, the nurse should administer 2 tablets of levothyroxine.
