A client who has heart failure with paroxysmal atrial tachycardia is receiving digoxin (Lanoxin) 0.45 mg IV as the initial digitalizing dose. The pharmacy provides 0.25 mg/ml. How many ml should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["1.8"]

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

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

Plugging in the given values:

Volume (mL) = 0.45 mg / 0.25 mg/mL

Calculating the result:

Volume (mL) = 1.8 mL

Therefore, the nurse should administer 1.8 mL of digoxin.

Correct Answer is ["60"]

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 = 240 mL / 4 hours

Infusion Rate = 60 mL/hour

Since the feeding is half-strength, the nurse should program the enteral pump to deliver 60 mL/hour.

Correct Answer is ["0.13"]

Explanation

To calculate the volume of phytonadione (AquaMEPHYTON) to be administered, we can use the following formula:

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

First, let's convert the desired dose from micro-grams to milligrams:

250 mcg x (1 mg / 1000 mcg) = 0.25 mg

Then, plug in the values into the formula:

Volume (mL) = 0.25 mg / 2 mg/mL

Calculating the result:

Volume (mL) = 0.125 mL

Rounding to the nearest hundredth, the nurse should administer 0.13 mL of phytonadione (AquaMEPHYTON).
