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 C
Explanation
To determine the number of tablets needed, we can set up a proportion:
x tablets / 7.5 mg = 1 tablet / 5 mg
Cross-multiplying:
5x = 7.5
Solving for x:
x = 7.5 / 5
x = 1.5
Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.
Therefore, the nurse should administer 2 tablets of metolazone.
Correct Answer is ["2"]
Explanation
To calculate the number of tablets needed, we can set up a proportion:
x tablets / 500 mg = 1 tablet / 250 mg
Cross-multiplying:
250x = 500
Solving for x:
x = 500 / 250
x = 2
Therefore, the nurse should administer 2 tablets of azithromycin per dose.
