Answer 3

Correct Answers:

20

Rationale :

◆ Order = 500 mg PO

◆ Bottle = 125 mg/5 mL

◆ Proportion: 500÷125=4500 = 4500÷125=4 doses of 125 mg

◆ Volume = 4×5=20 mL

◆ Measure 20 mL accurately

Answer 4

Correct Answers:

1.5

Rationale :

🔶 Formula: mL to give = Units ordered ÷ Units per mL

🔶 Numbers: 7,500 units ÷ (5,000 units/mL)

🔶 Math: 7,500 ÷ 5,000 = 1.5 mL

🔶 Result: Give 1.5 mL IV once.

Answer 5

Correct Answers:

0.5

Rationale :

🔷 Formula: mL to give = Ordered dose ÷ Concentration

🔷 Numbers: 1 mg ÷ (2 mg/mL)

🔷 Math: 1 ÷ 2 = 0.5 mL

🔷 Result: Draw up 0.5 mL for IV push (use appropriate dilution/rate per policy).

Answer 6

Correct Answers:

2

Rationale :

💠 Convert: 0.125 mg = 125 mcg per tablet

💠 Need: 250 mcg total

Answer 7

Correct Answers:

667

Rationale :

◈ Formula: Rate (mL/hr) = Volume ÷ Time(hr)

◈ Time: 45 min = 0.75 hr

◈ Math: 500 mL ÷ 0.75 hr = 666.7 → 667 mL/hr (nearest whole)

◈ Result: Set pump to 667 mL/hr.

Answer 8

Correct Answers:

100

Rationale :

◆ Formula: Rate = Volume ÷ Time(hr)

◆ Time: 30 min = 0.5 hr

◆ Math: 50 mL ÷ 0.5 hr = 100 mL/hr

◆ Result: Program 100 mL/hr.

Answer 9

Correct Answers:

3.1

Rationale :

♢ Find concentration: 400,000 units ÷ 5 mL = 80,000 units/mL

♢ Formula: mL to give = Units ordered ÷ Units per mL

♢ Math: 250,000 ÷ 80,000 = 3.125 mL → 3.1 mL

♢ Result: Draw up 3.1 mL IM (check max IM volume/site).

Answer 10

Correct Answers:

0.5

Rationale :

⬖ Formula: mL to give = Dose ÷ Concentration

⬖ Numbers: 63 mg ÷ (125 mg/mL)

⬖ Math: 63 ÷ 125 = 0.504 mL → 0.5 mL (to the tenth; 0.50 to the hundredth)

⬖ Result: Administer 0.5 mL IV (follow dilution/rate guidelines).
