Correct Answer is C
Explanation
Identify the ordered dose and tablet strength
Ordered Dose: 125 mcg (0.125 mg)
Tablet Strength: 0.25 mg per tablet
Calculate the number of tablets to administer
Number of Tablets = Ordered Dose ÷ Tablet Strength
Number of Tablets = 0.125 ÷ 0.25
= 0.5
Correct Answer is C
Explanation
Identify the ordered dose and available concentration
Ordered Dose: 1.5 million units
Available: 3 million units in 5 mL
Calculate the volume to administer
Volume = (Ordered Dose ÷ Vial Dose) × Vial Volume
Volume = (1,500,000 ÷ 3,000,000) × 5
Volume = 0.5 × 5
= 2.5 mL
