The physician ordered Cardene 5mg/hr. The pharmacy sends cardene 25 mg in 250 mL normal saline to the floor. At what rate will the nurse at the IV pump to achieve the correct dose

Expert Solution

Answer: Given that Cardene was ordered at 5mg/hr and we have 25mg in 250ml Normal Saline (NS);

= 25mg - 250ml

5mg - ?

= 5 X 250 / 25 = 50ml / hr

Volume per hour = 50ml / hr

Drops per minute = Total volume per hour X 1/3 (drop factor for clear fluids)

= 50 X 1/3

= 16.6 drops per minute or 17 drops per minute (rounding off)
