Dosage calculation mg per kg flashcards

What is mg per kg?

Milligrams per kilogram (mg/kg) is a dosaging unit that relates a drug's dosage to the patient's weight.

True or false: Dosage calculations are only necessary for children.

False, because dosage calculations are essential for patients of all ages, including adults.

Calculate: 500 mg for 70 kg patient.

Dosage = 500 mg / 70 kg = 7.14 mg/kg

Difference between mg/kg and mg/lb.

mg/kg is based on kilograms, while mg/lb is based on pounds. 1 kg = 2.2 lbs.

What factors affect dosage calculations?

Age, weight, organ function, and health conditions can all influence dosage requirements.

Calculate dosage for a 60 kg patient: 300 mg.

Dosage = 300 mg / 60 kg = 5 mg/kg.

Fill in the blank: 1 kg equals _____ lbs.

1 kg equals 2.2 lbs.

What is the importance of accurate dosage calculation?

Accurate dosage ensures therapeutic effectiveness while preventing toxicity and side effects.

True or false: Higher weight always means higher dosage.

False, because other factors like health status also influence dosage.

Convert 150 mg for a 50 kg patient to mg/kg.

Dosage = 150 mg / 50 kg = 3 mg/kg.

What is the formula for calculating mg/kg?

Formula: $\displaystyle Dosage (mg/kg) = \\frac{Total\,dosage\,(mg)}{Weight\,(kg)}$

Calculate for 80 kg: 800 mg.

Dosage = 800 mg / 80 kg = 10 mg/kg.

Which is NOT a factor in dosage calculation?

Patient's favorite color is NOT a factor.

True or false: Dosage can be adjusted based on renal function.

True, because renal function affects drug clearance and dosage needs.

Fill in the blank: A dosage of 4 mg/kg for a 75 kg patient equals _____ mg.

A dosage of 4 mg/kg for a 75 kg patient equals 300 mg.

Why is weight important in dosage calculations?

Weight ensures the dosage is proportionate to the patient's body mass, enhancing safety.

Calculate: 250 mg for 55 kg patient.

Dosage = 250 mg / 55 kg = 4.55 mg/kg.
