Answer 3

Correct Answers:

2.4

Rationale :

✏️Formula:

♦️Volume = Dose ÷ Concentration

✏️Weight conversion:

♦️130 lb ÷ 2.2

= 59.09 kg

✏️Dose:

♦️8 units/kg × 59.09 kg

= 472.72 units

✏️Calculation:

♦️472.72 ÷ 200 units/mL

= 2.3636 mL

✏️Rounding: Nearest tenth → 2.4 mL

Answer 4

Correct Answers:

5

Rationale :

✍️Daily dose:

✔️150 mg in 3 equal doses → 50 mg per dose

✍️Formula:

✔️Volume = Dose ÷ Concentration

✍️Given concentration:

✔️50 mg/5 mL

= 10 mg/mL

✍️Calculation:

✔️50 mg ÷ 10 mg/mL

= 5 mL

Answer 6

Correct Answers:

0.71

Rationale :

🟪Formula:

⚫Volume = Dose ÷ Concentration

🟪Given:

⚫Dose = 250 mg; Reconstituted concentration = 350 mg/mL

🟪Calculation:

⚫250 ÷ 350

= 0.714285… mL

🟪Rounding: Nearest hundredth

→ 0.71 mL

Answer 8

Correct Answers:

57

Rationale :

✍️Weight conversion:

☑️178 lb ÷ 2.2

= 80.91 kg

✍️Dose:

☑️140 mg/kg × 80.91 kg

= 11,327.27 mg

✍️Formula:

☑️Volume = Dose ÷ Concentration

✍️Given concentration:

☑️200 mg/mL → 11,327.27 ÷ 200

= 56.64 mL

✍️Rounding: Nearest whole

→ 57 mL
