A composite figure is made up of simpler figures.

To find the area of a composite figure, calculate the areas of the simpler figures.  Multiply the two areas together.  Subtract the areas of any figures that were removed.

Which formula should be used to calculate the volume of a prism with a base that is a composite figure.    

The four steps of the FIRE framework are:

An ICU patient has become hypotensive.  Order:  Start Dopamine 6 mcg/kg/min; increase titration at 1 mcg/kg/min to maintain a systolic blood pressure of at least 100. The IV drip you have on hand is 400 mg Dopamine in D5W 100 ml. Your patient weighs 150 lbs. How many ml/hr will you set your flow rate? Record your answer using one decimal place. [BLANK-1] ml/hr

An IV of 1000 ml NS is running at 100 ml/hr.   How many hours will this IV run? Record your answer using a whole number. [BLANK-1] hours

The recommended IM dosage of Medication Z for children is 10 mg/kg/day in 2 equally divided doses.   How many mg will you give in one dose for a child weighing 42 kg? Record your answer using a whole number. [BLANK-1] mg

Order: 1000 ml D5 0.45 NS to infuse at 125 ml/hr. Start the IV fluids at 0900.   What time will it be completed? Using military time, record your answer to the nearest minute. Record your answer using whole numbers. [BLANK-1]

An IV of 500 ml NS is running at 100 ml/hr.   How many hours will this IV run? Record your answer using a whole number. [BLANK-1] hours

You are initiating intravenous Heparin protocol on a newly admitted patient. The patient weighs 192 pounds. The physician’s orders are: Bolus dose of 60 units/kg IV, rounded to the nearest 100 units (e.g., 6850 units would be rounded to 6900 units).  Begin IV infusion of heparin at 17 units/kg/hr.  Obtain PTT every 6 hours and adjust the infusion using the heparin protocol scale. You have Heparin 25,000 units/250 ml (100 units/ml).   Heparin Protocol Scale: PTT < 35       Bolus 70 units/kg and increase drip by 4 units/kg/hr PTT 35-54    Bolus 35 units/kg and increase drip by 3 units/kg/hr PTT 55-85    Therapeutic – no change PTT 86-100  Decrease drip by 2 units/kg/hr PTT > 100    Hold infusion 1 hour; decrease drip by 3 units/kg/hr, then restart drip How many units should the nurse administer for this patient’s initial bolus? Record your answer using a whole number. Round to the nearest 100 units. [BLANK-1] units  How many ml should the nurse administer for this patient’s initial bolus? Record your answer using a whole number. [BLANK-2] ml How many ml/hour should the nurse infuse the heparin after the bolus is given? Record your answer using a whole number. [BLANK-3] ml/hr After the infusion has been running for 6 hours, the PTT is 94.   According to the protocol, how many units should the nurse administer as the bolus for a PTT of 94? Record your answer using a whole number. Round to the nearest 100 units. [BLANK-4] units The nurse should change the continuous infusion rate to how many ml/hour for a PTT of 94? Record your answer using a whole number. [BLANK-5] ml/hr
