Chapter Summary • Milliliters (m. L), rather than cubic centimeters (cc) are the preferred unit of measure for volume. • All syringe calibrations must be read at the top ring of the plunger. • Large-capacity hypodermic syringes (5, 12, 20, 35 m. L) are calibrated in increments from 0. 2 m. L to 1 m. L. Medical Dosage Calculations: A Dimensional Analysis Approach, Tenth Edition June L. Olsen • Anthony P. Giangrasso • Dolores Shrimpton Copyright © 2012, © 2008 by Pearson Education, Inc. All rights reserved.

Chapter Summary • Small-capacity hypodermic syringes (2, 21/2, 3 m. L) are calibrated in tenths of a milliliter (0. 1 m. L). • The 0. 5 m. L and 1 m. L hypodermic (tuberculin) syringes are calibrated in hundredths of a milliliter (0. 01 m. L). They are the preferred syringes for use in measuring a dose of 1 milliliter or less.

All rights reserved.

Chapter Summary • The calibrations on hypodermic syringes differ; therefore, be very careful when measuring medications in syringes. • Insulin syringes are designed for measuring and administering U-100 insulin. They are calibrated for 100 units per m. L. • Standard insulin syringes have a capacity of 100 units. Medical Dosage Calculations: A Dimensional Analysis Approach, Tenth Edition June L. Olsen • Anthony P. Giangrasso • Dolores Shrimpton Copyright © 2012, © 2008 by Pearson Education, Inc. All rights reserved.

Chapter Summary • Lo-Dose insulin syringes are used for measuring small amounts of insulin. They have a capacity of 50 units or 30 units. • For greater accuracy, use the smallest capacity syringe possible to measure and administer doses. However, avoid filling a syringe to its capacity. Medical Dosage Calculations: A Dimensional Analysis Approach, Tenth Edition June L. Olsen • Anthony P. Giangrasso • Dolores Shrimpton Copyright © 2012, © 2008 by Pearson Education, Inc. All rights reserved.

Chapter Summary • When measuring two types of insulin in the same syringe, Regular insulin is always drawn up in the syringe first. Think: first clear, then cloudy. • The total volume when mixing insulins is the sum of the two insulin amounts. Medical Dosage Calculations: A Dimensional Analysis Approach, Tenth Edition June L. Olsen • Anthony P. Giangrasso • Dolores Shrimpton Copyright © 2012, © 2008 by Pearson Education, Inc. All rights reserved.

Chapter Summary • Insulin syringes are for measuring and administering insulin only. Tuberculin syringes are used to measure and administer other medications that are less than 1 m. L. Confusion of the two can cause a medication error. • The prefilled single-dose syringe is to be used once and then discarded. Medical Dosage Calculations: A Dimensional Analysis Approach, Tenth Edition June L. Olsen • Anthony P. Giangrasso • Dolores Shrimpton Copyright © 2012, © 2008 by Pearson Education, Inc.

Chapter Summary • Syringes intended for injections should not be used to measure or administer oral medications. • Use safety syringes to prevent needle stick injuries.
