A patient is to receive an IV drip of the following: Sodium Heparin 80,000 units Sodium Chloride Injection $(0.45 \%) \quad 1000 \mathrm{~mL}$ a. How many milliliters per hour must be administered to achieve a rate of 1000 units of sodium heparin per hour? b. If the IV set delivers 50 drops $/ \mathrm{mL}$, how many drops per minute should be administered?

Key Concepts

IV Infusion Rate Calculation

This concept involves determining the amount of fluid to be delivered over a specific period to achieve a prescribed rate of medication dosage. It requires understanding the concentration of the medication in the IV solution and how that translates to units per time frame, ensuring the patient receives the correct dose.

Proportional Reasoning in Medication Dosing

Proportional reasoning is used to relate the known concentration of a medication in a solution to the desired dosage rate, typically using ratios. This technique allows healthcare professionals to scale the infusion rate appropriately based on the concentration and the required dose.

Drop Factor in IV Administration

The drop factor is a specific measurement relating the number of drops per milliliter delivered by a particular IV administration set. Understanding the drop factor is crucial for converting a milliliter-per-hour rate into a drops-per-minute rate, ensuring accurate manual control of the infusion when an electronic pump is not used.
