Flashcard 1: What is the formula for doses per day when a medication is ordered $q24h$?

Answer: $\text{doses/day} = \frac{24}{24} = 1$. Divides 24 hours by the 24-hour interval to find the daily dose count.

Flashcard 2: Calculate mL per dose: ordered dose $80\ mg$; supply concentration is $16\ \text{mg/mL}$.

Answer: $5\ mL$. Divides the ordered milligrams by the concentration to compute the milliliters needed per dose.

Flashcard 3: What is the formula for doses per day when a medication is ordered $q^6h$?

Answer: $\text{doses/day} = \frac{24}{6} = 4$. Divides 24 hours in a day by the 6-hour interval to determine the number of doses administered daily.

Flashcard 4: Calculate mg per dose: order $40\ \text{mg/kg/day}$, weight $15\ kg$, frequency $q12h$.

Answer: $300\ mg/dose$. Divides the total daily milligrams by the number of doses (2 for q12h) to calculate milligrams per dose.

Flashcard 5: State the formula to convert a required dose in mg to tablets when supply is $\text{mg/tablet}$.

Answer: $\text{tablets} = \frac{mg}{\text{mg/tablet}}$. Divides the required milligrams by the strength per tablet to determine the number of tablets per dose.

Flashcard 6: Calculate mL per dose: ordered dose $125\ mg$; supply concentration is $25\ \text{mg/mL}$.

Answer: $5\ mL$. Divides the ordered milligrams by the supply concentration to determine the volume in milliliters per dose.

Flashcard 7: Calculate the dose in mg: order $10\ \text{mg/kg/dose}$ for a child weighing $18\ kg$.

Answer: $180\ mg$. Multiplies the mg/kg/dose rate by the child's weight to compute the total milligrams per dose.

Flashcard 8: Calculate mg per dose: order $30\ \text{mg/kg/day}$, weight $10\ kg$, frequency $q^8h$.

Answer: $100\ mg/dose$. Divides the total daily milligrams by the number of doses (3 for q8h) to obtain milligrams per dose.

Flashcard 9: Identify the correct mg/kg setup: order is $12\ \text{mg/kg/dose}$ and weight is $8\ kg$.

Answer: $12\ \text{mg/kg} \times 8\ kg$. Multiplies the mg/kg rate by the weight in kilograms to set up the calculation for total dose in milligrams.

Flashcard 10: Calculate tablets per dose: ordered dose $250\ mg$; supply is $125\ \text{mg/tablet}$.

Answer: $2\ \text{tablets}$. Divides the ordered milligrams by the milligrams per tablet to find the number of tablets required.

Flashcard 11: Find the mg/dose: order $15\ \text{mg/kg/dose}$, weight $6\ kg$, give $q12h$.

Answer: $90\ mg/dose$. Multiplies the mg/kg/dose rate by the weight to compute the milligrams per dose, independent of q12h frequency.

Flashcard 12: What is the formula for doses per day when a medication is ordered $q^8h$?

Answer: $\text{doses/day} = \frac{24}{8} = 3$. Divides 24 hours by the 8-hour interval to calculate the daily dose frequency.

Flashcard 13: Find the mg/dose: order $60\ \text{mg/kg/day}$, weight $20\ kg$, frequency $q^6h$.

Answer: $300\ mg/dose$. Divides the total daily milligrams by the 4 doses (for q6h) to determine milligrams per dose.

Flashcard 14: What is the formula for doses per day when a medication is ordered $q12h$?

Answer: $\text{doses/day} = \frac{24}{12} = 2$. Divides 24 hours by the 12-hour interval to compute doses per day.

Flashcard 15: Calculate the total daily dose in mg: order $25\ \text{mg/kg/day}$ for a child weighing $12\ kg$.

Answer: $300\ mg/day$. Multiplies the mg/kg/day rate by the weight to find the total daily milligrams required.

Flashcard 16: Identify the correct step if weight is given in lb for a $\text{mg/kg}$ order before calculating mg.

Answer: $\text{Convert lb to kg: } kg = \frac{lbs}{2.2}$. Ensures weight is in kilograms by dividing pounds by 2.2 prior to applying the mg/kg dosage calculation.

Flashcard 17: Calculate tablets per dose: ordered dose $75\ mg$; supply is $50\ \text{mg/tablet}$.

Answer: $1.5\ \text{tablets}$. Divides the ordered milligrams by the tablet strength to calculate the number of tablets per dose.

Flashcard 18: What is the formula for calculating a single dose in mg when the order is $\text{mg/kg/dose}$?

Answer: $mg = (\text{mg/kg/dose}) \times kg$. Multiplies the dosage per kilogram per dose by the patient's weight to determine the total milligrams for a single dose.

Flashcard 19: State the formula to convert a required dose in mg to mL using a concentration labeled $\text{mg/mL}$.

Answer: $mL = \frac{mg}{\text{mg/mL}}$. Divides the required milligrams by the concentration in mg/mL to obtain the volume in milliliters needed.

Flashcard 20: State the formula to calculate mg per dose from an order written as $\text{mg/kg/day}$ and given $q\#h$.

Answer: $mg/dose = \frac{(\text{mg/kg/day})\times kg}{\text{doses/day}}$. Divides the total daily milligrams by the number of doses per day to find the milligrams per individual dose.

Flashcard 21: What is the formula for calculating total daily dose in mg when the order is $\text{mg/kg/day}$?

Answer: $mg/day = (\text{mg/kg/day}) \times kg$. Multiplies the daily dosage per kilogram by the weight to calculate the total milligrams required per day.

Flashcard 22: Calculate the childs weight in kg: weight is $44\ lb$. Round to the nearest tenth.

Answer: $20.0\ kg$. Divides pounds by 2.2 and rounds to the nearest tenth to convert to kilograms for accurate dosing.

Flashcard 23: State the formula to convert a weight in pounds to kilograms for pediatric dosing calculations.

Answer: $kg = \frac{lbs}{2.2}$. Divides pounds by 2.2 to convert to kilograms, ensuring compatibility with mg/kg dosing units.

Flashcard 24: State the formula to convert a weight in kilograms to a weight in pounds for dosing work.

Answer: $lbs = kg \times 2.2$. Multiplies kilograms by the conversion factor of 2.2 to obtain equivalent pounds for dosing calculations.

Flashcard 25: Calculate the childs weight in kg: weight is $22\ lb$. Round to the nearest tenth.

Answer: $10.0\ kg$. Divides pounds by 2.2 and rounds to the nearest tenth to obtain weight in kilograms.
