Weight-Based Oral Medication Dosage Calculation Practice

Vocabulary and dosage calculation practice flashcards based on weight-based oral medication administration transcript.

Kilogram conversion from Pounds

The standard conversion used where weight in kilograms is determined by dividing the weight in pounds by $2.2$ (e.g., $44 \text{ lb} \times \frac{1 \text{ kg}}{2.2 \text{ lb}} = 20 \text{ kg}$).

Fractional Pound conversion from Ounces

The conversion where ounces are divided by $16$ to be added to the pounds for a total weight decimal (e.g., $8 \text{ oz} = \frac{8}{16} = 0.5 \text{ lb}$).

PO

A medical abbreviation meaning 'by mouth' or 'per os,' indicating that the medication should be administered orally.

PRN

A medical abbreviation for 'pro re nata,' which translates to 'as needed,' commonly used for fever or pain medications.

mg/kg/day

A weight-based dosing instruction indicating the total milligrams of a medication to be administered per kilogram of patient weight over a full 24-hour period.

mg/kg/dose

A weight-based dosing instruction indicating the milligrams of medication to be administered per kilogram of patient weight for each individual dose.

Divided Doses Calculation

The process of taking the total calculated daily milligram or milliliter amount and dividing it by the frequency of administration (e.g., 'divided into 2 equal doses' means dividing the total by 2).

Question 1 Dosage (Amoxicillin)

For a $20 \text{ kg}$ child ordered $40 \text{ mg/kg/day}$ divided into 2 doses with a supply of $400 \text{ mg}/5 \text{ mL}$, the dose is $5 \text{ mL} \text{ per dose}$.

Question 2 Dosage (Cephalexin)

For a $15 \text{ kg}$ child ordered $25 \text{ mg/kg/day}$ divided into 3 doses with a supply of $250 \text{ mg}/5 \text{ mL}$, the dose is $2.5 \text{ mL} \text{ per dose}$.

Question 6 Dosage (Amoxicillin)

For a $30 \text{ kg}$ child ordered $45 \text{ mg/kg/day}$ divided into 2 doses with a supply of $400 \text{ mg}/5 \text{ mL}$, the dose is $8.4 \text{ mL} \text{ per dose}$.

Question 7 Dosage (Prednisolone)

For a $13.9 \text{ kg}$ child ($30 \text{ lb } 8 \text{ oz}$) ordered $1 \text{ mg/kg/day}$ divided into 2 doses with a supply of $15 \text{ mg}/5 \text{ mL}$, the dose is $2.3 \text{ mL} \text{ per dose}$.

Question 8 Dosage (Clindamycin)

For an $18.2 \text{ kg}$ child ordered $30 \text{ mg/kg/day}$ divided into 4 doses with a supply of $75 \text{ mg}/5 \text{ mL}$, the dose is $9.1 \text{ mL} \text{ per dose}$.

Question 9 Dosage (Cefdinir)

For an $8.5 \text{ kg}$ child ($18 \text{ lb } 12 \text{ oz}$) ordered $14 \text{ mg/kg/day}$ divided into 2 doses with a supply of $250 \text{ mg}/5 \text{ mL}$, the dose is $1.2 \text{ mL} \text{ per dose}$.

Question 10 Dosage (Fluconazole)

For a $12.5 \text{ kg}$ child ordered $6 \text{ mg/kg/day}$ with a supply of $10 \text{ mg/mL}$, the dose to administer is $7.5 \text{ mL}$.

Question 11 Dosage (Amoxicillin)

For a $17.3 \text{ kg}$ child ordered $50 \text{ mg/kg/day}$ divided into 2 doses with a supply of $400 \text{ mg}/5 \text{ mL}$, the dose is $5.4 \text{ mL} \text{ per dose}$.

Question 12 Dosage (Acetaminophen)

For an $11.9 \text{ kg}$ child ordered $15 \text{ mg/kg}$ every 4 hours with a supply of $160 \text{ mg}/5 \text{ mL}$, the dose rounded to the nearest tenth is $5.6 \text{ mL} \text{ per dose}$.

Question 13 Dosage (Cefdinir)

For a $16.1 \text{ kg}$ child ordered $14 \text{ mg/kg/day}$ divided into 2 doses with a supply of $250 \text{ mg}/5 \text{ mL}$, the dose rounded to the nearest tenth is $2.3 \text{ mL} \text{ per dose}$.

Question 14 Dosage (Ibuprofen)

For a $21.8 \text{ kg}$ child ordered $10 \text{ mg/kg/dose}$ with a supply of $100 \text{ mg}/5 \text{ mL}$, the dose is $10.9 \text{ mL} \text{ per dose}$.

Question 15 Dosage (Azithromycin)

For a $13.5 \text{ kg}$ child ($29 \text{ lb } 12 \text{ oz}$) ordered Azithromycin with a supply of $200 \text{ mg}/5 \text{ mL}$ using a $12 \text{ mg/kg}$ calculation, the dose is $4.1 \text{ mL} \text{ per dose}$.
