A client with hypernatremia is to receive an IV infusion of 1000 ml 5% dextrose in water to be infused over 6 hours. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["167"]

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 = 1000 mL / 6 hours

Calculating the result:

Infusion Rate ≈ 166.67 mL/hour

Rounding to the nearest whole number, the nurse should program the infusion pump to deliver 167 mL/hour

Correct Answer is ["10.5"]

Explanation

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 ["2"]

Explanation

Calculating the Ferrous Fumarate Dose

Problem: Administer ferrous fumarate 3 mg/kg/day PO three times daily to an 88-pound child. The available concentration is 100 mg/5 mL.

Steps:

Convert pounds to kilograms:

88 pounds x (1 kg / 2.20462 pounds) ≈ 39.9 kg

Calculate the daily dose:

3 mg/kg/day x 39.9 kg = 119.7 mg/day

Calculate the dose per administration (TID):

119.7 mg/day / 3 doses = 39.9 mg/dose

Set up a proportion:

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

We know the desired dose (39.9 mg) and the concentration of the medication (100 mg/5 mL).

Proportion:

x mL / 39.9 mg = 5 mL / 100 mg

Cross-multiply:

100x = 199.5

Solve for x:

x = 199.5 / 100

x ≈ 2

Answer: The child should receive approximately 2 mL of ferrous fumarate oral suspension for each dose.
