A client receives a prescription for 0.9% normal saline with inamrinone 0.1 grams/100 ml at a rate of 400 mcg/minute. What is the correct ml/hour setting for the infusion pump?

To determine the correct ml/hour setting for the infusion pump, the total dosage and rate of infusion must be understood in relation to the medication concentration in the solution.

In this scenario, the patient is receiving inamrinone at a concentration of 0.1 grams in 100 ml of normal saline. First, convert grams to milligrams, since the dosages in clinical practice often utilize milligrams for clarity. Therefore, 0.1 grams is equivalent to 100 mg.

The infusion rate is specified as 400 mcg (micrograms) per minute. To convert this into milligrams for consistency, note that 400 mcg is 0.4 mg (since there are 1000 mcg in 1 mg).

Next, we must determine how many ml of the solution is needed to provide this dosage of inamrinone. The total amount of inamrinone available in the 100 ml solution is 100 mg. If the solution is delivering 0.1 grams (or 100 mg) in 100 ml, then for every 100 ml, there are 100 mg of inamrinone available.

To calculate the ml needed to deliver the required 0.4 mg/minute of
