As a nursing student, you will be responsible for administering medication to your patients, and understanding how to measure medications accurately is crucial to your success. One of the most common methods for administering medication is through drops with nursing measurements.

In addition to administering medication, nurses must also take other measurements, such as vital signs, height, weight, and blood glucose levels. These measurements help nurses assess the patient’s overall health and ensure they receive the appropriate treatment.

How Many Drops (gtt) in a Milliliter (mL)?

The abbreviation “gtt” stands for “drops,” and it’s often used interchangeably with the term “drops.” As a general rule, a drop is 0.05 mL which is about 20 drops per milliliter. In hospitals, drops are mainly used for IV medication. IV tubing sizes range from 10 drops/mL to 60 drops/mL.

Using gtt is standard in medical settings to ensure that all health care professionals use the same terminology when measuring medication.

Understanding how to measure medication accurately is a vital skill for nurses when administering medications that have a low therapeutic index, meaning that the difference between a therapeutic dose and a toxic dose is small. 

Examples of such medications include digoxin, heparin, and insulin. With these types of medications, even a small measurement error can have severe consequences.

Nurse Measurements

As a nurse, you’ll be responsible for measuring a wide range of medications. These medications may come in various forms, such as tablets, capsules, liquids, and injectables. Accurately measuring these medications requires understanding the specific medication’s dosing and the patient’s unique needs.

When measuring medication, nurses should always double-check their calculations and ensure that the medication is administered at the appropriate time and correctly. Additionally, it’s essential to keep detailed records of all medication administrations to ensure that the patient is receiving the proper dosage.

I cannot express enough gratitude for Nurse Mike and this wonderful platform he has created. I had a subscription to SimpleNursing the entire 2 years of my nursing school career and it was the best resource I had available to me. The visuals, the explanations, the memory tricks, the songs, the study guides, and the test questions are brilliant.

Before starting nursing school, I was a C-average student. I didn't think I'd be competent enough and make it through my second semester. I was told about SimpleNursing and purchased it immediately. Long story short, I graduated nursing school with honors and passed all of my classes with As and Bs only. I would have never been able to do that without the help of SimpleNursing. Nurse Mike teaches in the only way that I am able to learn and I cannot thank him enough.
