A client receives a prescription for diazepam 12.5 mg IV. The available concentration is 5 mg per ml. How many ml should the nurse administer? (Enter the numerical value only. If rounding is required round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["2.5"]

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

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

Plugging in the given values:

Volume (mL) = 12.5 mg / 5 mg/mL

Calculating the result:

Volume (mL) = 2.5 mL

Therefore, the nurse should administer 2.5 mL of diazepam.

Correct Answer is ["1"]

Explanation

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

x tablets / 0.05 mg = 1 tablet / 0.1 mg

Cross-multiplying:

0.1x = 0.05

Solving for x:

x = 0.05 / 0.1

x = 0.5

Therefore, the nurse should administer 0.5 tablets of levothyroxine sodium (Synthroid).

Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.

So, the nurse should administer 1 tablet.

Correct Answer is ["5.8"]

Explanation

To calculate the infusion rate, we'll follow these steps:

1. Calculate the desired dose rate in mcg/minute:

Desired Dose Rate = Weight (kg) x Dose (mcg/kg/minute)

Desired Dose Rate = 86 kg x 8 mcg/kg/minute

Desired Dose Rate = 688 mcg/minute

2. Convert micro-grams to milligrams:

688 mcg x (1 mg / 1000 mcg) = 0.688 mg/minute

3. Calculate the concentration of dopamine in the IV solution:

Dopamine Concentration = Dopamine (mg) / Solution Volume (mL)

Dopamine Concentration = 800 mg / 500 mL

Dopamine Concentration = 1.6 mg/mL

4. Set up a proportion:

x mL/hour / 0.688 mg/minute = 60 minutes/hour / 1.6 mg/mL

5. Cross-multiply and solve for x:

x mL/hour = 0.688 mg/minute x 60 minutes/hour / 1.6 mg/mL

x mL/hour ≈ 25.8 mL/hour

Therefore, the nurse should program the infusion pump to deliver approximately 25.8 mL/hour.
