The healthcare provider prescribes the adjustment of the IV hourly rate based on
the nasogastric tube (NGT) output q4h for a client who had abdominal surgery
yesterday. From 1200 to 1600, the NGT output was 240 ml, and the IV of D5W
0.45% NS was infused at a rate of 100 ml/hour. At 1600 the nurse should regulate
the IV to deliver how many ml/hour to replace this fluid loss? (Enter numeric
value only.)

160
To calculate the hourly rate of IV fluid replacement based on the last 4 hours of
NGT output, the nurse should calculate an average hourly output by dividing 240
ml by 4 hours = 60 ml NGT output q1h. The nurse should then add the 60 ml loss
per hour to the present infusion rate of 100 ml/hr, totaling an infusion rate of 160
ml/hour for the next 4 hours.

, The healthcare provider prescribes propofol (Diprivan) at 8 mcg/kg/minute for a
client during conscious sedation. The drug is dispensed as 100 mg/50 ml 0.9%
normal saline. The client's weight is 198 pounds. The nurse should program the
infusion pump to deliver how many ml/hour? (Enter numeric value only. If
rounding is required, round to the nearest tenth.)
Incorrect
Correct Responses
21.6
The client's weight in kg is 90 kg (198 pounds / 2.2 pounds). Next, determine the
total mcg in the NS infusion (1 mg : 1000 mcg :: 100 mg : 100,000 mcg) and the
IV concentration per ml (100,000 mcg : 50 ml :: X mcg : 1 ml). 100, =
2000 mcg/ml. Then, calculate the prescribed dose (mcg/kg/min) x 60 min/hour x
kilograms divided by concentration (mcg/ml). 8 x 90 x 60 divided by 2000 = 21.6
ml/hour

The healthcare provider prescribes an intermittent infusion of nafcillin (Unipen)
800 mg IV for a pediatric client. The drug is dispensed in a concentration of 250
mg/ml, and the recommended infusion concentration is 40 mg/ml. When adding
the prescribed dose to the volume control device, how many ml of IV solution
should the nurse add to dilute? (Enter numeric value only. If rounding is required,
round to the nearest tenth.)
Incorrect
Correct Responses
16.8
First, calculate the amount of milliliters of medication needed to provide 800 mg
of nafcillin. Prescribed dose (800 mg) divided by dose on hand (250 mg/ml)
equals 3.2 ml Next, determine the recommended concentration using equivalent
fractions. 800 mg/X = 40 mg/1 ml 40X = 800 = 20 ml (the total volume at the
recommended concentration) 20 ml (total volume) minus the 3.2 ml (800 mg
dose) equals an additional 16.8 ml of fluid to be added to the volume control
device to obtain the recommended concentration.
