NHA Pharmacy Technician Practice Exam

To determine how many milliliters are equivalent to 20 drops, it's essential to know the standard volume that a drop represents in medical contexts. Typically, one drop is approximately equal to 0.05 milliliters. Therefore, to find the total volume for 20 drops, the calculation would be:

20 drops x 0.05 ml/drop = 1 ml

This calculation confirms that 20 drops is equivalent to 1 milliliter.

Understanding this conversion is crucial in pharmacy practice as it ensures accurate dosing of medications, especially when measuring liquid formulations. Knowing how to convert drops to milliliters allows pharmacy technicians to provide guidance on proper medication administration and to prepare prescriptions correctly.
