HESI EXIT DOSAGE CALCULATIONEXAM QUESTIONS AND VERIFIED
ANSWERS
Order: Morphine 2 mg IV every 4 hours PRN for pain.
Available: Morphine 10 mg/mL.
How many mL will you administer per dose?
A. 0.2 mL
B. 0.3 mL
C. 0.4 mL
D. 0.5 mL
Answer: A. 0.2 mL
Rationale: Dose=(Ordered DoseAvailable Dose)×Volume Available\text{Dose} = \left( \frac{\
text{Ordered Dose}}{\text{Available Dose}} \right) \times \text{Volume
Available}Dose=(Available DoseOrdered Dose)×Volume Available
Dose=(2 mg10 mg/mL)×1 mL=0.2 mL\text{Dose} = \left( \frac{2 \text{ mg}}{10 \text{
mg/mL}} \right) \times 1 \text{ mL} = 0.2 \text{ mL}Dose=(10 mg/mL2 mg)×1 mL=0.2 mL
Question 2
Order: Furosemide 40 mg IV push.
Available: Furosemide 10 mg/mL.
How many mL will you administer per dose?
A. 2 mL
B. 3 mL
C. 4 mL
D. 5 mL
Answer: A. 4 mL
Rationale: Dose=(Ordered DoseAvailable Dose)×Volume Available\text{Dose} = \left( \frac{\
text{Ordered Dose}}{\text{Available Dose}} \right) \times \text{Volume
Available}Dose=(Available DoseOrdered Dose)×Volume Available
Dose=(40 mg10 mg/mL)×1 mL=4 mL\text{Dose} = \left( \frac{40 \text{ mg}}{10 \text{
mg/mL}} \right) \times 1 \text{ mL} = 4 \text{ mL}Dose=(10 mg/mL40 mg)×1 mL=4 mL
,Question 3
Order: Amoxicillin 500 mg PO every 8 hours.
Available: Amoxicillin 250 mg tablets.
How many tablets will you administer per dose?
A. 1 tablet
B. 2 tablets
C. 3 tablets
D. 4 tablets
Answer: B. 2 tablets
Rationale: Dose=(Ordered DoseAvailable Dose)\text{Dose} = \left( \frac{\text{Ordered Dose}}
{\text{Available Dose}} \right)Dose=(Available DoseOrdered Dose)
Dose=(500 mg250 mg)=2 tablets\text{Dose} = \left( \frac{500 \text{ mg}}{250 \text{ mg}} \
right) = 2 \text{ tablets}Dose=(250 mg500 mg)=2 tablets
Question 4
Order: Dopamine 400 mg in 250 mL D5W to infuse at 20 mcg/kg/min.
Patient weight: 70 kg.
How many mL/hour will you set the IV pump to deliver?
A. 10 mL/hr
B. 15 mL/hr
C. 21 mL/hr
D. 35 mL/hr
Answer: C. 21 mL/hr
Rationale: Dosage (mcg/min)=20 mcg/kg/min×70 kg=1400 mcg/min\text{Dosage (mcg/min)}
= \text{20 mcg/kg/min} \times \text{70 kg} = 1400 \text{
mcg/min}Dosage (mcg/min)=20 mcg/kg/min×70 kg=1400 mcg/min
Dosage (mg/min)=1400 mcg/min1000=1.4 mg/min\text{Dosage (mg/min)} = \frac{1400 \
text{ mcg/min}}{1000} = 1.4 \text{ mg/min}Dosage (mg/min)=10001400 mcg/min=1.4 mg/min
Concentration=400 mg250 mL=1.6 mg/mL\text{Concentration} = \frac{400 \text{ mg}}{250 \
text{ mL}} = 1.6 \text{ mg/mL}Concentration=250 mL400 mg=1.6 mg/mL
Rate (mL/min)=1.4 mg/min1.6 mg/mL=0.875 mL/min\text{Rate (mL/min)} = \frac{1.4 \
text{ mg/min}}{1.6 \text{ mg/mL}} = 0.875 \text{
mL/min}Rate (mL/min)=1.6 mg/mL1.4 mg/min=0.875 mL/min
Rate (mL/hour)=0.875 mL/min×60 min/hour=52.5 mL/hour\text{Rate (mL/hour)} = 0.875 \text{
mL/min} \times 60 \text{ min/hour} = 52.5 \text{
mL/hour}Rate (mL/hour)=0.875 mL/min×60 min/hour=52.5 mL/hour
,Question 5
Order: Heparin 1000 units/hr IV.
Available: Heparin 25,000 units in 500 mL D5W.
How many mL/hr will you set the IV pump to deliver?
A. 20 mL/hr
B. 10 mL/hr
C. 5 mL/hr
D. 2 mL/hr
Answer: A. 20 mL/hr
Rationale: Concentration=25000 units500 mL=50 units/mL\text{Concentration} = \frac{25000 \
text{ units}}{500 \text{ mL}} = 50 \text{ units/mL}Concentration=500 mL25000 units
=50 units/mL Rate=1000 units/hr50 units/mL=20 mL/hr\text{Rate} = \frac{1000 \text{
units/hr}}{50 \text{ units/mL}} = 20 \text{ mL/hr}Rate=50 units/mL1000 units/hr=20 mL/hr
Question 6
Order: Lidocaine 1 mg/min IV.
Available: Lidocaine 2 grams in 500 mL D5W.
How many mL/hr will you set the IV pump to deliver?
A. 15 mL/hr
B. 30 mL/hr
C. 60 mL/hr
D. 75 mL/hr
Answer: C. 30 mL/hr
Rationale: Concentration=2000 mg500 mL=4 mg/mL\text{Concentration} = \frac{2000 \
text{ mg}}{500 \text{ mL}} = 4 \text{ mg/mL}Concentration=500 mL2000 mg=4 mg/mL
Rate=1 mg/min4 mg/mL=0.25 mL/min\text{Rate} = \frac{1 \text{ mg/min}}{4 \text{ mg/mL}}
= 0.25 \text{ mL/min}Rate=4 mg/mL1 mg/min=0.25 mL/min
Rate=0.25 mL/min×60 min/hour=15 mL/hr\text{Rate} = 0.25 \text{ mL/min} \times 60 \
text{ min/hour} = 15 \text{ mL/hr}Rate=0.25 mL/min×60 min/hour=15 mL/hr
Question 7
Order: Dextrose 10% in water to infuse at 75 mL/hr.
How many grams of dextrose will the patient receive in 24 hours?
A. 100 grams
B. 150 grams
, C. 180 grams
D. 200 grams
Answer: C. 180 grams
Rationale: Dextrose concentration=10%=10 grams/100 mL\text{Dextrose concentration} =
10\% = 10 \text{ grams/100 mL}Dextrose concentration=10%=10 grams/100 mL
Infusion rate=75 mL/hr\text{Infusion rate} = 75 \text{ mL/hr}Infusion rate=75 mL/hr
Total infusion=75 mL/hr×24 hours=1800 mL\text{Total infusion} = 75 \text{ mL/hr} \times 24 \
text{ hours} = 1800 \text{ mL}Total infusion=75 mL/hr×24 hours=1800 mL
Total dextrose=10 grams/100 mL×1800 mL=180 grams\text{Total dextrose} = 10 \text{
grams/100 mL} \times 1800 \text{ mL} = 180 \
text{ grams}Total dextrose=10 grams/100 mL×1800 mL=180 grams

A. 50 mL/hr
B. 75 mL/hr
C. 100 mL/hr
D. 150 mL/hr
Answer: C. 100 mL/hr
Rationale: Rate=1000 mL10 hours=100 mL/hr\text{Rate} = \frac{1000 \text{ mL}}{10 \
text{ hours}} = 100 \text{ mL/hr}Rate=10 hours1000 mL=100 mL/hr
