A medication order reads 200 mg, but the available dose is 500 mg/10 mL. How many mL should be administered?
A. 8 mL
Calculation: Ordered Dose = 200 mg Available Dose = 500 mg Available Volume = 10 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (200 / 500) × 10 = 0.4 × 10 = 4 mL
B. 4 ml
Calculation: Ordered Dose = 200 mg Available Dose = 500 mg Available Volume = 10 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (200 / 500) × 10 = 0.4 × 10 = 4 mL
C. 2 ml
Calculation: Ordered Dose = 200 mg Available Dose = 500 mg Available Volume = 10 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (200 / 500) × 10 = 0.4 × 10 = 4 mL
D. 6mL
Calculation: Ordered Dose = 200 mg Available Dose = 500 mg Available Volume = 10 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (200 / 500) × 10 = 0.4 × 10 = 4 mL

Full Explanation
Calculation:
Ordered Dose = 200 mg
Available Dose = 500 mg
Available Volume = 10 mL
Volume to administer = (Ordered Dose / Available Dose) × Available Volume
= (200 / 500) × 10
= 0.4 × 10
= 4 mL

Which of the following is the base unit of weight in the metric system used in clinical practice?
A. Meter
Meter: The meter is the base unit of length in the metric system, not weight. It measures distance or height rather than mass.
B. Milligram
Milligram: A milligram is a subunit of the gram (1/1000 of a gram) and is used for precise measurements, but it is not the base unit itself.
C. Gram
Gram: The gram is the base unit of weight (mass) in the metric system commonly used in clinical practice. All other weight measurements, such as milligrams and kilograms, are derived from the gram.
D. Litre
Liter: The liter is the base unit of volume in the metric system and is used for measuring fluids, not weight.

A nurse is reviewing a medication order for a pediatric patient. The order states, "Administer 5 mg/kg of medication X orally." The child weighs 22 kg. How much medication should the nurse administer?
A. 95 mg
Calculation: Dosage = 5 mg/kg Weight = 22 kg Dose = Dosage × Weight = 5 × 22 = 110 mg
B. 100 mg
Calculation: Dosage = 5 mg/kg Weight = 22 kg Dose = Dosage × Weight = 5 × 22 = 110 mg
C. 110 mg
Calculation: Dosage = 5 mg/kg Weight = 22 kg Dose = Dosage × Weight = 5 × 22 = 110 mg
D. 120 mg
Calculation: Dosage = 5 mg/kg Weight = 22 kg Dose = Dosage × Weight = 5 × 22 = 110 mg
Full Explanation
Calculation:
Dosage = 5 mg/kg
Weight = 22 kg
Dose = Dosage × Weight
= 5 × 22
= 110 mg
