Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: Calculate pump rate: order $12\ \text{mg/hr}$; solution $0.5\ \text{mg/mL}$. What is \text{mL/hr}?

Answer: $24\ \text{mL/hr}$. Divides ordered hourly dose by concentration to obtain the necessary pump setting.

Flashcard 2: What is the formula for infusion rate in \text{mcg/kg/min} from mg/hr, weight, and units?

Answer: $\text{mcg/kg/min}=\frac{\text{mg/hr}\times1000}{\text{kg}\times60}$. Converts mg/hr to mcg by multiplying by 1000, then divides by weight in kg and minutes per hour for per-minute rate.

Flashcard 3: What is the formula for infusion rate in \text{mg/kg/hr} from mg/hr and weight?

Answer: $\text{mg/kg/hr}=\frac{\text{mg/hr}}{\text{kg}}$. Divides the hourly dose by patient weight to normalize the infusion rate per kilogram.

Flashcard 4: What is the formula for pump rate \text{mL/hr} from ordered dose rate and concentration?

Answer: $\text{mL/hr}=\frac{\text{mg/hr}}{\text{mg/mL}}$. Divides ordered hourly dose by solution concentration to find the required infusion rate.

Flashcard 5: What is the formula for mg/hr delivered from solution concentration and pump rate?

Answer: $\text{mg/hr}=\text{mg/mL}\times\text{mL/hr}$. Multiplies solution concentration by infusion rate to determine the hourly drug delivery.

Flashcard 6: What is the formula to convert \text{gtt/min} to \text{mL/hr} using drop factor?

Answer: $\text{mL/hr}=\frac{\text{gtt/min}\times60}{\text{gtt/mL}}$. Multiplies drops per minute by minutes per hour and divides by drop factor to convert to hourly volume.

Flashcard 7: What is the formula for IV infusion time in \text{hr} from volume and rate?

Answer: $\text{hr}=\frac{\text{mL}}{\text{mL/hr}}$. Divides total volume by hourly rate to determine the duration of IV infusion.

Flashcard 8: What is the formula for infusion rate in \text{mcg/min} from mg/hr?

Answer: $\text{mcg/min}=\frac{\text{mg/hr}\times1000}{60}$. Converts mg/hr to mcg by multiplying by 1000, then divides by minutes per hour for per-minute rate.

Flashcard 9: Calculate drip rate: $100\ \text{mL/hr}$ with a $15\ \text{gtt/mL}$ set. What is \text{gtt/min}?

Answer: $25\ \text{gtt/min}$. Applies the drip rate formula by multiplying mL/hr by drop factor and dividing by 60.

Flashcard 10: Calculate \text{mg/hr}: concentration $2\ \text{mg/mL}$ and pump rate $30\ \text{mL/hr}$. What is mg/hr?

Answer: $60\ \text{mg/hr}$. Multiplies concentration by infusion rate to find the hourly drug administration amount.

Flashcard 11: What is the formula for drip rate in \text{gtt/min} using drop factor and mL/hr?

Answer: $\text{gtt/min}=\frac{\text{mL/hr}\times\text{gtt/mL}}{60}$. Multiplies hourly volume by drop factor and divides by minutes per hour to find drops per minute.

Flashcard 12: Convert to pump rate: $20\ \text{gtt/min}$ using a $10\ \text{gtt/mL}$ set. What is \text{mL/hr}?

Answer: $120\ \text{mL/hr}$. Converts drops per minute to mL/hr by multiplying by 60 and dividing by drop factor.

Flashcard 13: Identify the correct conversion from mg to mcg used in infusion-rate calculations.

Answer: $1\ \text{mg}=1000\ \text{mcg}$. Enables conversion from milligrams to micrograms, crucial for precise dosing in infusions.

Flashcard 14: Calculate \text{mcg/kg/min}: deliver $12\ \text{mg/hr}$ to a $60\ \text{kg}$ patient. What is the rate?

Answer: $3.33\ \text{mcg/kg/min}$. Converts mg/hr to mcg/kg/min using the formula with 1000 mcg/mg, divided by kg and 60 min/hr.

Flashcard 15: Calculate drip rate: $75\ \text{mL/hr}$ with a $60\ \text{gtt/mL}$ set. What is \text{gtt/min}?

Answer: $75\ \text{gtt/min}$. Uses the drip rate calculation, where mL/hr times drop factor divided by 60 yields drops per minute.

Flashcard 16: What deck type best fits NAPLEX Rates of Administration (recall, application, or both)?

Answer: both. Encompasses memorization of formulas and their practical use in calculating infusion parameters.

Flashcard 17: What is the formula for drip rate in \text{gtt/min} using mL, drop factor, and minutes?

Answer: $\text{gtt/min}=\frac{\text{mL}\times\text{gtt/mL}}{\text{min}}$. Multiplies total volume by drop factor and divides by total minutes for the drip rate over the infusion period.

Flashcard 18: Calculate infusion time: $250\ \text{mL}$ at $50\ \text{mL/hr}$. What is the time in hours?

Answer: $5\ \text{hr}$. Divides volume by hourly rate to determine the total time needed for complete infusion.

Flashcard 19: Identify the correct conversion for hours to minutes used in drip-rate calculations.

Answer: $1\ \text{hr}=60\ \text{min}$. Provides the essential factor to convert between hourly and per-minute rates in infusion calculations.

Flashcard 20: What is the formula for total drug delivered (mg) from mg/hr and time in hours?

Answer: $\text{mg}=\text{mg/hr}\times\text{hr}$. Multiplies hourly dose rate by infusion time to calculate cumulative drug amount delivered.

Flashcard 21: What is the formula for IV infusion rate in \text{mL/hr} from volume and time?

Answer: $\text{mL/hr}=\frac{\text{mL}}{\text{hr}}$. Divides total volume by infusion time to yield the hourly flow rate for IV administration.

Flashcard 22: Calculate total dose delivered: run $2\ \text{mg/hr}$ for $6\ \text{hr}$. How many mg are delivered?

Answer: $12\ \text{mg}$. Multiplies hourly rate by total hours to compute the overall drug quantity infused.
