Question

a client who has heart failure with paroxysmal atrial tachycardia is receiving digoxin 0.45 mg iv as the initial digitalizing dose. the pharmacy provides 0.25 mg/ml. how many ml should the nurse administer? (enter numerical value only. if rounding is required, round to the nearest tenth.)

Explanation:

Step1: Recall the formula for volume calculation

The formula to calculate the volume \( V \) (in mL) is \( V=\frac{\text{Dose Required (mg)}}{\text{Concentration (mg/mL)}} \). Here, the dose required is \( 0.45 \) mg and the concentration is \( 0.25 \) mg/mL.

Step2: Substitute the values into the formula

Substitute the given values into the formula: \( V = \frac{0.45}{0.25} \).

Step3: Perform the division

Calculate \( \frac{0.45}{0.25}=1.8 \).

Answer:

1.8
