An adult client with myasthenia gravis is receiving pyridostigmine (Mestinon) 126 mg PO every 4 hours. The drug is available as 60 mg in 5 ml syrup. How many ml should the nurse administer? (If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["10.5"]

To calculate the volume of pyridostigmine to be administered, we can use the following formula:

Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)

However, the concentration is given in mg/5 mL. We need to convert it to mg/mL:

Concentration (mg/mL) = 60 mg / 5 mL = 12 mg/mL

Now, plug in the given values into the formula:

Volume (mL) = 126 mg / 12 mg/mL

Volume (mL) = 10.5 mL

Therefore, the nurse should administer 10.5 mL of pyridostigmine syrup.

Correct Answer is ["200"]

Explanation

To calculate the infusion rate, we'll use the following formula:

Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)

First, convert minutes to hours:

75 minutes x (1 hour / 60 minutes) = 1.25 hours

Then, plug in the values into the formula:

Infusion Rate = 250 mL / 1.25 hours

Calculating the result:

Infusion Rate ≈ 200 mL/hour

Therefore, the nurse should program the secondary infusion pump to deliver 200 mL/hour.

Correct Answer is ["83"]

Explanation

To calculate the infusion rate, we'll use the following formula:

Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)

Plugging in the given values:

Infusion Rate = 250 mL / 3 hours

Calculating the result:

Infusion Rate ≈ 83.33 mL/hour

Rounding to the nearest whole number, the nurse should program the infusion pump to deliver 83 mL/hour.
