Answer 2

Correct Answers:

0.3

Rationale :

Dose ordered × (Volume on hand ÷ Dose on hand)

60 mcg × (1 mL ÷ 200 mcg) = 60 ÷ 200 mL

60 ÷ 200 = 0.3 mL

Answer 3

Correct Answers:

0.8

Rationale :

Have: 80 mg in 2 mL

Step 1: Find mg per mL

80 mg ÷ 2 mL = 40 mg/mL

Step 2: Use ordered dose

Ordered: 30 mg

Volume (mL) = Ordered dose ÷ Concentration

Volume = 30 mg ÷ 40 mg/mL

Volume = 0.75 mL

Step 3: Round to nearest tenth

0.75 mL ≈ 0.8 mL

Answer 6

Correct Answers:

167

Answer 7

Correct Answers:

44

Rationale :

Volume = 100 mL

Time = 45 min

Drop factor = 20 gtt/mL

Step 1: gtt/min = (Volume × Drop factor) ÷ Time

gtt/min = (100 mL × 20 gtt/mL) ÷ 45 min

Step 2: Multiply

gtt/min = 2000 ÷ 45

Step 3: Divide

gtt/min ≈ 44.44 gtt/min

Step 4: Round to nearest whole number

gtt/min = 44 gtt/min

Answer 8

Correct Answers:

12

Rationale :

Dose ordered × (Volume on hand ÷ Dose on hand)

600 mg × (5 mL ÷ 250 mg)

= 600 × 5 ÷ 250

= 3000 ÷ 250

= 12 mL

Answer 9

Correct Answers:

111

Rationale :

Volume = 250 mL

Time = 45 min

Drop factor = 20 gtt/mL

Formula:

gtt/min = (Volume × Drop factor) ÷ Time

Substitute:

gtt/min = (250 mL × 20 gtt/mL) ÷ 45 min

gtt/min = 5000 ÷ 45

gtt/min ≈ 111.11

Round to nearest whole number:

gtt/min = 111
