2. Digoxin 0.375 mg PO daily is ordered. Digoxin 250 mcg tablets are available. The patient will receive ________tablet(s).

3. Diazepam 6 mg IM now is ordered. Calculate the dose and then indicate on the syringe the amount to be administered

Expert Solution

Answer 1

The drops per minute for an infusion can be calculated using the following equation.

Amount of fluid= 1 litre which is 1000 ml

Duration in hours=10

Duration in minutes=10*60=600

Drop factor=15

As per the above equation when we substitute the values

The drop factor is

Which is equal to 25 drops per minute or 25 gtts.

Answer 2

The dose of a drug can be calculated by the equation

According to this equation

Dose in hand = 250 mcg,This value must be converted into mg for easier calculation.

1mcg = 0.001 mg

250 mcg = 0.25 mg

Amount in hand = 1

Dose to be administered = 0.375mg

By substituting in the equation

we have to administer 1.5 tablets.

Answer 3

Diazepam normally comes in 1 mg per ml injection.so the below equation can be used

Dose to be administered =6 mg

Dose in hand=1 mg

Amount in hand= 1ml

Amount to be administered =6/1*1

=6 ml.

You have to label 6 ml in syringe. And it should be given in devided dose if it is IM
