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.)
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 ["2"]
Explanation
To calculate the number of tablets needed, we can set up a proportion:
x tablets / 3 mg = 1 tablet / 1.5 mg
Cross-multiplying:
1.5x = 3
Solving for x:
x = 3 / 1.5
x = 2
Therefore, the nurse should administer 2 tablets of dexamethasone for each dose.
Correct Answer is ["37.3"]
Explanation
To convert Fahrenheit to Celsius, you can use the following formula:
Celsius = (Fahrenheit - 32) x 5/9
In this case, the Fahrenheit temperature is 99.2. Plugging it into the formula:
Celsius = (99.2 - 32) x 5/9
Celsius = 67.2 x 5/9
Celsius = 37.33
Rounding to the nearest tenth, the Celsius temperature is 37.3.
