A healthcare provider prescribes a medication dosage of 1 quart. Convert this dosage to milliliters.
A. 720 mil
Calculation: Ordered Dose = 1 quart Conversion = 1 quart = 960 mL Volume in mL = Number of quarts × 960 mL = 1 × 960 = 960 mL
B. 480 ml
Calculation: Ordered Dose = 1 quart Conversion = 1 quart = 960 mL Volume in mL = Number of quarts × 960 mL = 1 × 960 = 960 mL
C. 1200 mL
Calculation: Ordered Dose = 1 quart Conversion = 1 quart = 960 mL Volume in mL = Number of quarts × 960 mL = 1 × 960 = 960 mL
D. 960 mL
Calculation: Ordered Dose = 1 quart Conversion = 1 quart = 960 mL Volume in mL = Number of quarts × 960 mL = 1 × 960 = 960 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
A patient is prescribed 500 mg of a medication. The available concentration is 250 mg/5 mL. How many milliliters should be administered?
A. 10 ml
Calculation: Ordered Dose = 500 mg Available Dose = 250 mg Available Volume = 5 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (500 / 250) × 5 = 2 × 5 = 10 mL
B. 20 ml
Calculation: Ordered Dose = 500 mg Available Dose = 250 mg Available Volume = 5 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (500 / 250) × 5 = 2 × 5 = 10 mL
C. 15 mL
Calculation: Ordered Dose = 500 mg Available Dose = 250 mg Available Volume = 5 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (500 / 250) × 5 = 2 × 5 = 10 mL
D. 5 mL
Calculation: Ordered Dose = 500 mg Available Dose = 250 mg Available Volume = 5 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (500 / 250) × 5 = 2 × 5 = 10 mL
Full Explanation
Calculation:
Ordered Dose = 500 mg
Available Dose = 250 mg
Available Volume = 5 mL
Volume to administer = (Ordered Dose / Available Dose) × Available Volume
= (500 / 250) × 5
= 2 × 5
= 10 mL
