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 ["2.5"]

Explanation

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

Volume to administer = (Prescribed dose) / (Concentration)

Plugging in the given values:

Volume to administer = 25 mg / (40 mg/4 mL)

Volume to administer = 25 mg x (4 mL / 40 mg)

Volume to administer = 2.5 mL

Therefore, the nurse should administer 2.5 mL of furosemide (Lasix).

Correct Answer is ["4.9"]

Explanation

Step 1: Calculate the concentration of dopamine in the IV solution:

400 mg / 250 mL = 1.6 mg/mL

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

12 mL/hour x (1 hour / 60 minutes) = 0.2 mL/minute

Step 3: Calculate the dopamine infusion rate in mg/minute:

0.2 mL/minute x 1.6 mg/mL = 0.32 mg/minute

Step 4: Convert milligrams to micro-grams:

0.32 mg x (1000 mcg / 1 mg) = 320 mcg/minute

Step 5: Calculate the dopamine infusion rate in mcg/kg/minute:

320 mcg/minute / 65 kg ≈ 4.9 mcg/kg/minute

Therefore, the client is receiving approximately 4.9 mcg/kg/minute of dopamine.
