A patient receiving an intravenous infusion containing 40 mEq of potassium chloride in 1000
mL of Dextrose 5% in Half Normal Saline. The infusion has been running at a rate of 80 mL
per hour for the past 6.5 hours. Following a lab report showing the patient's serum
potassium level to be 3.5 mEq/L, the physician decides to increase the potassium while
slowing the infusion flow rate to 40 mL per hour. The physician prescribes potassium
chloride injection (14.99% KCI) to be added to the remainder of the 1000mL bag above such
that the patient will receive a total of 80 mEq of potassium over the remaining time for
completion of the infusion. How many MILLILITERS of the potassium chloride injection
should be added to the bag so the so the patient can receive a total of 80 mEq in the time
and fluid left? (KCI mw = 74.5) - CORRECT ANSWER -30.4ml
A 56 year old male patient weighing 160 lbs is on a heparin low dose protocol (from the
protocol in the ppt slides). The patient received no bolus and initiated a rate of 15
units/kg/hour 6 hours ago. Now, a PTT is performed on the patient and the vlue is 40
seconds. Based on the protocol from the ppt slides calculate the new infusion rate, in
MILLITERS PER HOUR, using heparin injection, 25,000 units/250 mL. - CORRECT ANSWER -
12.4ml/hr

50 mL/min = 10 mg/kg daily, divided into two dosesCrCl > 50 mL/min = 15 mg/kg daily,
divided into two doses
What is the patient's dose in MILLILITERS? - CORRECT ANSWER -90ml
