100 Convert pounds to kg by dividing 176 pounds by 2.2 pounds = 80 kg. Convert the IV concentration from mg to mcg. 1 mg : 1000 mcg :: 10 mg : 10,000 mcg. Infusion rate (48 ml/hour) x concentration (10,000 mcg/ml) divided by 60 minutes/hour x 80 kg = 48 x 10,000 divided by 60 x 80 = 480,000 / 4800 = 100 mcg/kg/minute.

The nurse should set the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

11.3 First, convert pounds to kg, 220 lb : X = 2.2 lb : 1 kg = 100 kg. Next, calculate the dosage per minute, 3 mcg/kg/min x 100 kg = 300 mcg/min. Convert mcg/min to mcg/hour, 300 mcg/min x 60 min=18,000 mcg/hour. Convert mcg/hr to mg/hour, 18,000 mcg/hr = 18.0 mg/hour. Calculate the rate, 400 mg : 250 ml = 18 mg : X ml 400X = 4500 X = 11.25 = 11.3 ml. So, 18 mg/11.3 ml should be infused at 11.3 ml/hour.

A child who is scheduled for a kidney transplant receives a prescription for basiliximab (Simulect) 20 mg IV 2 hours prior to surgery.

120 8 grams = 8,000 mg prescribed dose. Using the formula, D/H x Q, 8,000 mg / 200 mg x 1 ml = 40 ml of the 20% solution. Dilute the 40 ml to a 1:4 concentration for administration using ratio and proportion, 1 : 4 solution :: 40 ml : X X= 160 ml total volume to administer. Subtract total volume of 160 ml - 40 ml of 20% concentration = 120 ml diluent is added to obtain a 1:4 concentration.

The solution is to be administered at a rate of 2 mu/minute. The nurse should program the infusion pump to administer how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

6 First calculate the number of units/hour. 0.002 units/minute x 60 minutes = 0.12 units/hour. Next calculate the number of ml/hour needed to administer 0.12 units/hour. 20 units : 1,000 ml :: 0.12 units : X 20/0.12 :: 1,000/X 20X : 120 X = 6

At the end of the shift, the nurse is recording the fluid balance for a client receiving a continuous gastrostomy tube (GT) feeding. Based on the client's records, how many ml should the nurse record for the total fluid balance (intake - output) for the shift that started at 0700 and ended at 1900? (Enter numeric value only.) (Click on each image asset for additional information.)

695 The tube feeding is administered at 75 ml/hour for 11 hours (0700 - 1800) and then turned off for one hour because the residual is greater than 200 ml. 11 hours x 75 ml/hr = 825 ml. Three doses of 20 ml of medication are administered, with 10 ml of water used to flush the GT before and after each dose. 20 ml x 3 doses = 60 ml; 10 ml (flush) x 2 x 3 doses = 60 ml; so 825 ml + 60 ml + 60 ml = 945 ml. 250 ml of residual is removed and not replaced. 945 ml - 250 ml = 695 ml total fluid balance (Intake - output).

A client with septic shock receives a prescription for dextrose 5% in water with dopamine (Intropin) 0.6 grams/250 ml at a rate of 5 mcg/kg/minute. The client's weight is 148 lbs. The nurse should set the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

8 First convert the weight into kilograms: 148 pounds/2.2 kg = 67 kg. Next calculate the number of mcg/kg/minute: 5 x 67 x 1 minute = 335 mcg/min. Calculate the number of mcg/hour: 335 x 60 minutes = 20,100 mcg/hour. Now calculate the number of ml/hour needed to administer 20,100 mcg/hour: 600,000 mcg : 250 ml :: 20,100 mcg : X ml 600,000/20100 :: 250/X 600,000X = 5,02500 X = 8.375 (rounded to) 8 ml/hour.

If Acetaminophen in doses greater than 4 g/day is assumed to cause liver toxicity, what is the maximum number of 500 mg tablets a patient may "safely" take per day?

8 tablets/day

A client receives a prescription for an intravenous infusion 0.45% sodium chloride 500 ml to be infused over 6 hours. 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 whole number.)

83 Calculate using Volume/Time: 500 ml/6 hours = 83.3 ml/hour

A RPh fills 3 compounded Rxs using the following quantities of hydromorphone HCl: 1/8 oz., ¼ oz, 1-1/2 oz. How many ounces of drug remain in the original container of 3 oz of drug from which she withdrew the 3 amounts of drug?

9/8 oz. or 1.125 oz.

The nurse is preparing the change-of-shift report for a client who has a 265 ml secondary infusion that was started 2 hours ago at a rate of 85 ml/hour via an infusion pump. The nurse should report that how many ml remain to be infused by the on-coming nurse? (Enter numeric value only.)

95 85 ml x 2 hours = 170 ml has infused. 265 ml (total amount to be infused) - 170 ml (amount infused) = 95 ml remain to be infused.

A client is receiving dantrolene sodium (Dantrium) PO for malignant hyperthermia. The maximum safe dose is 8 mg/kg/day in 4 divided doses. The client currently weighs 48.5 kg. What is the maximum safe dose the nurse should administer? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

97 Determine the maximum number of mg this client should receive in a day: 48.5 kg x 8 mg/kg/day = 388 mg/day. Next determine how many mg the nurse should deliver each dose: 388 mg/4 doses = 97 mg.

A client is receiving an IV solution of sodium chloride 0.9% (Normal Saline) 250 ml with amiodarone (Cordarone) 1 gram at 17 ml/hour. How many mg/minute of amiodarone is infusing? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Convert grams to mg, 1 gram equals 1,000 mg. Using ratio and proportion - 1,000 mg : 250 ml :: X mg : 1ml 250X= 1,000 so X = 4 mg/ml is the solution concentration of amiodarone. The infusion rate (ml/hour) x concentration (mg/ml) divided by 60 minutes/hour 17 ml/hour x 4 mg/ml = 68/60 = 1.13 = 1.1 mg/minute.
