Answer 1

ANSWERS

1. Rocephin GM 1 IV q12h mixed in D5W = 150 ml

Time = infuse over 45 minutes

Drop factor = 15 gtt /ml

Drops /minute = [volume (ml) ÷Time per minute] ×Drop factor

= [150 ml ÷ 45 min] × 15 gtt /ml

= 50 drop/minute

Drip rate = 50 drops /minute

2.   Medication = 30ml of IV fluid

Time = over 45 minutes

Drip factor = 60 gtt /ml

Drops /minute = [volume (ml) ÷ Time per minute] ×Drop factor

= [30 ml ÷ 40 minutes] ×60gtt /ml

= 45 drops /minute

Drip rate = 45 drops /minute

3. Desired dose (D) = Tab. Apresoline 30mg

Available dose (H) = Tab. Apresoline 20 mg

Quantity =(desired dose ÷ available dose)× No: of tablets  

=( 30 ÷ 20) ×1

=1.5

The number of tablets = 1 and 1/2 tablets

4. Desired dose = 1.0 gm

Available dose =0.5 gm

Quantity = (desired dose ÷ available dose) ×No :of tablets

= (1.0gm ÷ 0.5 gm) ×1

= 2 tablets

The number of tablets = 2 tablets
