What You'll Learn
Understanding IV flow rates is a crucial topic for pharmacy technicians preparing for the PTCB (PTCE) exam. Intravenous (IV) medications are commonly prescribed, and pharmacy technicians must be able to accurately calculate and monitor IV flow rates to ensure patient safety. This section covers the key concepts, common mistakes, and study tips related to IV flow rates, as well as sample questions to help you prepare for the exam.
Key Concepts
Drop Factor
The number of drops per milliliter (mL) of a specific IV solution, usually between 10-20 drops/mL. This is used to calculate the number of drops per minute required to achieve a specific flow rate.
Flow Rate
The volume of IV solution that is delivered to the patient per unit of time, typically measured in milliliters per hour (mL/hr) or drops per minute (gtt/min).
Infusion Time
The duration of time required to infuse a specific volume of IV solution, calculated by dividing the total volume by the flow rate.
Volumetric Infusion Pump
A medical device that precisely controls the flow rate of IV solutions, ensuring accurate and consistent delivery to the patient.
Gravity Flow
The flow of IV solution without the use of an infusion pump, relying on the force of gravity to deliver the solution to the patient.
Common Mistakes to Avoid
- Incorrectly calculating the drop factor for a specific IV solution
- Failing to convert flow rates between different units (e.g., mL/hr to gtt/min)
- Misunderstanding the relationship between flow rate, infusion time, and total volume
- Confusing the use of gravity flow versus volumetric infusion pumps
- Neglecting to consider patient-specific factors that may affect IV flow rates, such as body weight or medication concentration
