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.)
Incorrect
Correct Responses
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 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). 100,000 / 50 = 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

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.

First, change the concentration of dispensed dopamine to mcg/ml. 1 mg : 1000 mcg :: 800 mg : X mcg = 800,000 mcg/500 ml = 1600 mcg/ ml. Using the formula, prescribed dose (8 mcg/kg/minute) x 60 minute/hour x weight (86 kg) divided by the concentration of the available drug (1600 mcg/ml) = 8 x 60 x 86 divided by 1600 = 25.8 ml/hour

The healthcare provider prescribes diltiazem (Cardizem) 0.87 mg PO four times daily for an infant who weighs 22 pounds. The recommended maximum dose is 3.5 mg/kg/day. What action should the nurse take?
Give the prescribed dosages.
Notify the healthcare provider. Correct
Ask the pharmacist to clarify the calculations.
Calculate the recommended maximum dose, 22 pounds = 10 kg, so 3.5 mg x 10 kg = 35 mg. Calculate the prescribed daily dose. 0.87 mg x 4 doses = 3.48 = 3.5 mg/day. The prescribed daily dose 3.5 mg/day is below the recommended dose of 35 mg, which may be a misplaced decimal in the prescription, so the healthcare provider should be notified (D) for clarification of the dosage.
