Mock

Question 1

Convert 300 micrograms to milligrams.

Answer 1

0.3 mg

300mcg/1000 = 0.3mg

Question 2

What volume should be administered for 400mg of X available as 50mg in 5mL?

Answer 2

40 mL

(400/50) x (5/1) = 8 x 5 = 40mL

Question 3

What volume should be administered for a patient prescribed 2mg of X with syrup containing 400 micrograms/mL?

Answer 3

5 mL

2mg = 2000mcg. (2000/400) x (1/1) = 2000/400 = 20/4 = 5mL

Question 4

What volume should be administered for a patient prescribed 3mg of X available as 4mg per 1mL?

Answer 4

0.75 mL

(3/ 4) x (1/1) = 0.75mL

Question 5

What volume should be administered for a patient prescribed 750 micrograms of X with ward stock containing 0.5mg/1mL?

Answer 5

1.5 mL

0.5mg = 500mcg. (750/500) x (1/1) = 750/500 = 75/50 = 1.5mL

Question 6

What dose is required for a patient weighing 79kg prescribed 1.5 mg/kg?

Answer 6

118.5 mg

1.5 x 79 = 118.5mg

Question 7

What volume should be administered for a patient requiring 21000 units of X available as 28000 units in 1mL?

Answer 7

0.75 mL

(21000/28000) x (1/1) = 21/28 = 0.75mL

Question 8

Calculate the rate in mL/hour for a patient to receive 800mL of X over 6 hours.

Answer 8

133.33 mL/hour

800/6 = 133.33 mL/hour

Question 9

Convert 150 milligrams to micrograms.

Answer 9

150000 mcg

150mg = 150 x 1000 = 150000 mcg

Question 10

Convert 675 micrograms to milligrams.

Answer 10

0.675 mg

675 mcg = 675/ 1000 = 0.675 mg

Question 11

Convert 25 grams to milligrams.

Answer 11

25000 mg

25 grams = 25 x 1000 = 25000mg

Question 12

How many 5mg tablets should be given for a prescription of 25mg penicillin?

Answer 12

5 tablets

25/5 = 5 tablets

Question 13

How many 500mg tablets should be given for a prescription of 3.5 grams of X?

Answer 13

7 tablets

3.5gram = 3500mg; 3500/500 = 35/5 = 7 tablets

Question 14

How many capsules should be given at each dose for 1800mg of X to be given per day in 3 equally divided doses with 300mg capsules?

Answer 14

2 capsules

1800/3 = 600mg for each dose; 600/300 = 6/3 = 2 capsules for each dose

Question 15

What volume of X should be administered for a prescription of 100 micrograms if X is supplied at 40 micrograms per 1mL?

Answer 15

2.5 mL

(100/40) x (1/1) = 100/40 = 10/4 = 2.5mL

Question 16

How many mg of X are there in 25mL if syrup contains X 155mg/5ml?

Answer 16

775 mg

25/5 = 5; 155 x 5 = 775mg

Question 17

What volume should be administered for a patient prescribed 160mg gentamycin available as 80mg per 2mL?

Answer 17

4 mL

(160/80) x 2 = 4mL

Question 18

What volume should be administered for a patient prescribed 0.125mg of digoxin available in 500mcg per 2mL?

Answer 18

0.5 mL

0.125 (mg) x1000 = 125 mcg; (125/500) x 2 = 0.5mL

Question 19

How many tablets will need to be prescribed for a 28 days supply for a patient prescribed 0.5mg of drug X per day with 250mcg tablets available?

Answer 19

56 tablets

0.5 (mg) x 1000 = 500mcg; 500/250 = 2 tablets per day; 2 (tablets) x 28 (days) = 56 tablets

Question 20

Calculate the rate (mL/hr) of the infusion for a patient prescribed noradrenaline 0.2mcg/kg/min weighing 57.6kg with an infusion of noradrenaline 2mg/100mL.

Answer 20

34.56 mL/hr

0.2 (mcg) x 57.6 (kg) x 60 (min) = 691.2 (mcg); 691.2 (mcg) / 1000 = 0.6912 (mg); 0.6912 (mg) /2 (mg) x 100 (mL) = 34.56mL/hr
