Order, digoxin (Lanoxin) 0.25 mg IM daily. Available digoxin (Lanoxin) 0.5 mg/2 mL How many mL will the nurse administer?

Answer and Explanation

The Correct Answer is ["1"]

To calculate the amount of mL the nurse should administer, we can use a proportion based on the available concentration of digoxin (Lanoxin) and the prescribed dose.

The available concentration is 0.5 mg/2 mL, which means there are 0.5 mg of digoxin in 2 mL of solution.

The prescribed dose is 0.25 mg.

Now we can set up the proportion:

0.5 mg / 2 mL = 0.25 mg / x mL

Cross-multiplying, we have:

0.5 mg * x mL = 2 mL * 0.25 mg

0.5x = 0.5

Dividing both sides by 0.5, we get:

x = 0.5 / 0.5

x = 1

Therefore, the nurse should administer 1 mL of digoxin (Lanoxin) to deliver a dose of 0.25 mg.

Correct Answer is ["30"]

Explanation

1 fluid ounce (fl oz) is equal to approximately 29.57 milliliters (ml). The conversion factor between fluid ounces and milliliters is not an exact value due to the difference between the U.S. fluid ounce and the metric milliliter. However, for most practical purposes, 1 fluid ounce is commonly rounded to 30 milliliters (ml) for simplicity.

Correct Answer is ["1.25"]

Explanation

To calculate the dose of Lasix (furosemide) in milliliters (ml), we can set up a proportion using the available concentration and the prescribed dose.

The available concentration is 80 mg/2 ml, which means there are 80 mg of Lasix in 2 ml of solution.

The prescribed dose is 50 mg.

Setting up the proportion:

80 mg / 2 ml = 50 mg / x ml

Cross-multiplying:

80 mg * x ml = 2 ml * 50 mg

80x = 100

Dividing both sides by 80:

x = 100 / 80

x = 1.25

Therefore, the dose of Lasix 50 mg IV would be approximately 1.25 ml.
