Answer 1

Answers

Q1: Answer is 818.1 mg

This can be calculated by:

Ordered dose – Cyclosporine 12mg/kg/day

Patient weight is 150lbs

Here, 1kg = 2.2 lbs

So, to convert weight in lbs to weight in kg, divide the number of lbs by 2.2

To find the mg,

mg = 12mg   ×  1kg    ×  150 lbs

  1 kg 2.2 lbs 1

  = 818.1 mg

Q2: Answer is 250ml/hr

This can be calculated by:

Order – 3000ml TPN

Time period – 1900 to 0700 = 12 hrs

To find the ml/hr,

ml/hr = 3000ml ÷ 12

= 250 ml/hr

Q3: Answer is 20.8 ml/hr

This can be calculated by:

Order – 500 ml Dextran

Time period –infusion over 24 hours

To find the ml/hr,

ml/hr = 500ml ÷ 24 hrs

= 20.8 ml/hr

Q4: Answer is 33drops/min

This can be calculated by:

Order – Pepcid 20mg in 100ml D5W to infuse over 30minutes.

Drop factor – 10gtt/ml

To find the drops per minute,

Number of drops per minute = Total volume × Drop factor

  Time (in mints)   

= 100 ml ÷ 30 mints × 10 gtt/ml   

= 33.3 drops/min

= 33 drops/min
