Hi,
Can anyone explain
Rx
Morphine sulfate 500mg in a 100 ml PCA unit to deliver 0.05 mg/min
Dosing to start at 8:00 AM tomorrow.
Upon consultation, the prescriber decides to allow bolus PRN dosing of 2 mg with a lockout of 1-h intervals. Assuming that the patient uses all bolus-dosing intervals, approximately how long will the PCA last?
