Copyright ©2012, ©2008 by Pearson Education, Inc. All rights reserved. Medical Dosage Calculations: A Dimensional Analysis Approach, Tenth Edition June L. Olsen Anthony P. Giangrasso Dolores Shrimpton Chapter Summary Milliliters (mL), 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 mL) are calibrated in increments from 0.2 mL to 1mL.

Copyright ©2012, ©2008 by Pearson Education, Inc. All rights reserved. Medical Dosage Calculations: A Dimensional Analysis Approach, Tenth Edition June L. Olsen Anthony P. Giangrasso Dolores Shrimpton Chapter Summary Small-capacity hypodermic syringes (2, 2- 1/2, 3mL) are calibrated in tenths of a milliliter (0.1 mL). The 0.5 mL and 1 mL hypodermic (tuberculin) syringes are calibrated in hundredths of a milliliter (0.01 mL). They are the preferred syringes for use in measuring a dose of 1 milliliter or less.

Copyright ©2012, ©2008 by Pearson Education, Inc. All rights reserved. Medical Dosage Calculations: A Dimensional Analysis Approach, Tenth Edition June L. Olsen Anthony P. Giangrasso Dolores Shrimpton 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 mL. Standard insulin syringes have a capacity of 100 units.

Copyright ©2012, ©2008 by Pearson Education, Inc. All rights reserved. Medical Dosage Calculations: A Dimensional Analysis Approach, Tenth Edition June L. Olsen Anthony P. Giangrasso Dolores Shrimpton 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.

Copyright ©2012, ©2008 by Pearson Education, Inc. All rights reserved. Medical Dosage Calculations: A Dimensional Analysis Approach, Tenth Edition June L. Olsen Anthony P. Giangrasso Dolores Shrimpton 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.

Copyright ©2012, ©2008 by Pearson Education, Inc. All rights reserved. Medical Dosage Calculations: A Dimensional Analysis Approach, Tenth Edition June L. Olsen Anthony P. Giangrasso Dolores Shrimpton 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 mL. Confusion of the two can cause a medication error. The prefilled single-dose syringe is to be used once and then discarded.

Copyright ©2012, ©2008 by Pearson Education, Inc. All rights reserved. Medical Dosage Calculations: A Dimensional Analysis Approach, Tenth Edition June L. Olsen Anthony P. Giangrasso Dolores Shrimpton Chapter Summary Syringes intended for injections should not be used to measure or administer oral medications. Use safety syringes to prevent needle stick injuries.
