### Medication Competency Review

.

• Cup = 240

• ½ cup = 120

• ¼ cup – 60

• 1/8 cup = 30

• 1/3 cup = 80

• 2/3 cup = 160

• Convert 4500 mcg = mg

• Step 1: Move 3 spaces to the left.

• ANSWER 4.5 mg

• Convert 4.5 mg to mcg

• Step 1: Multiply by 1000, or move the decimal point 3 places to the right

• 4.5 0 0 or 4.5 x 1000 = 4500

• ANSWER 4500 mcg

• Convert grams 56.7 grams to milligrams:

• Step 1: Multiply by 1000, or move the decimal point 3 places to the right

• Step 2: 56.7 grams x 1000 = 56,700 milligrams

or 5 6, 7 0 0

• ANSWER 56,700 milligram

• Convert 56,700 mg to grams:

• Step 1: Move the decimal point 3 places to the left

ANSWER 56.7 grams

• You must add 40 meq of a drug to each liter of IV fluid. The drug is available as a 2 meq solution/mL.

• How many mLs of medication will you need to add to the IV medication?

• Step One: 40 = 20 mL 2

• Answer: 20 mL

• Give medication at 3 mcg/kg/min. Available as medication 800 mg/500 mLs D5W. Weight -154 pounds.

• How many mg/hr is the patient receiving?

Step 1: 154/2.2 = 70 kg

Step 2: .003 mg x 70 kg x 60 min = 12.6mg/hr

• Give medication at 3 mcg/kg/min. Available as medication 800 mg/500 mLs D5W. Weight -154 pounds. How many mLs per hour?

Step 1:154/2.2 = 70 kg

Step 2: .003 mg x 70 kg x 60 min= 12.6 mg/hr

Step 3: 12.6 mg/800 mg x 500 = 7.88 mL/hr

• Give medication at 3 mcg/kg/min. Available as medication 800 mg/500 mLs D5W. Weight -154 pounds.

• How many mLs /min is the patient receiving?

Step 1: 154/2.2 = 70 kg

Step 2: .003 mg x 70 kg x 60 min =12.6 mg/hr

Step 3: 12.6 mg/800 mg x 500 =7.88 mL/hr

Step 4: 7.88 mL/hr/60 min = 0.13 mL/min

ANSWER: 0.13 mL/min

• Give medication 0.5 mg. Available as 2 mg/2 mLs

Step 1: 0.5 mg = 0.25 mL per 1 mL

2 mL

Step 2: 0.25 mL x 2 mLs= 0.5 mL

ANSWER: 0.5 mL

• Give 250 mg of medication that comes as 2 grams/2 mLs.

Step 1: Change grams to mgs.

2 grams = 2000 mg

Step 2: 250 mg = 0.125 per mL

2000 mg

Step 3: 0.125 mL x 2 = 0.25 mL

Step 4: Answer 0.25 mL

• Your patient is on a medication drip of 1000 units per hour. Pharmacy sent you a medication of 20,000 units in 500 mL D5W.

• How many mLs/hour are you going to give your patient?

Step 1: 500 mL X 1000 units = 500,000 20,000 units x 1 20,000 units

Answer: 25 mL/hr

• You are to give medication at 2mg/min. Pharmacy sent up medication 1 gram in 500 mLs of D5W.

• How would you give this dose in mL/hr using an infusion pump?

Step 1: Convert from grams to mg.

1 gram to 1000 mg

Step 2: 1000 mg = 2 mg/mL

500 mL

Step 3: 2 mg /min x 60 min = 120 mg/hr

Step 4: 120 mg/hr = 60 mL/hr

2 mg

ANSWER: 60 mL/hr

• You are to give medication at 2mg/min. Pharmacy sent up medication 1 gram in 500 mLs of D5W.

• How many mLs per minute will you give?

Step 1: Convert from grams to mg. 1 gram to 1000 mg

Step 2: 1000 mg = 2 mg/mL  = 1 mL

500 mL

ANSWER: 1 mL/min

• Give 20 meq of medication in 100 mLs of D5 W over 4 hours IV piggyback. How will you set this up using a volume pump? mL/hour?

Step 1: 100 x X

240 60

Step 2: 240X = 6000

Step 3: X = 25 mL/hr

ANSWER: 25 mL/hr

Medication comes in container labeled 375mcg/ml, you are going to give 30 mg BID.

How many mLs is the patient receiving daily?

How many ounces?

Step 1: 375 mcg/ml = 30,000 mcg

1 X

Step 2: 375x=30,000

x= 80 mL (BID) = 160 ml Daily

Step 3: 160 = 5.33 ounces

Medication to be given at 2 mg/min. Bag from pharmacy has 2 grams in 500 mLs D5W. How many mLs /min is the patient receiving?

Step 1: 2 mg = 2000 mg

X 500 mL

Step 2: (2 mg) x (500 mL)=10x =0.5 ml/min

(2000 mg)/min

Medication to be given at 2 mg/min. Bag from pharmacy has 2 grams in 500 mLs D5W. How many mLs /hour is the patient receiving?

Step 1: 2 mg = 2000 mg

X 500 mL

Step 2: (2 mg) x (500 mL)=10 mL =0.5 mL/min

(2000 mg)/min

Step 3: (0.5) x 60 minutes = 30 mL/hr
