Homework Assignment 2

The physician ordered heparin sodium 3000 units subcutaneously every 12 hours. The medication is available as 5000 units/mL. Select the syringe to use and the amount of heparin to give. Use the formula method to calculate the dosage. A. 0.6 mL; 1-mL syringe B. 0.3 mL; Insulin U-50 C. 0.3 mL; 1-mL syringe D. 0.6 mL; Insulin U-100

A. 0.6 mL; 1-mL syringe When solving any problem, first check that the order and the supply are in the same weight measure. For this problem, no equivalent is necessary. Estimate the amount to give. Formula Method: 3000 units/5000 units × 1 mL = 3/5 = 0.6 mL. The 1-mL syringe is used for a maximum volume of 1 mL of medication. Although heparin is ordered in units, an insulin syringe is not used because insulin syringes are used only for insulin administration.

The client is to receive octreotide acetate 0.05 mg subcutaneously daily. The medication is available as octreotide acetate 100 mcg/1 mL. Which syringe should the nurse use to administer the medication? Use proportion (fractions) to calculate the dosage. A. 1-mL precision B. Insulin U-50 C. 3 mL D. Insulin U-100

A. 1-mL precision When solving any problem, first check that the order and the supply are in the same weight measure. For this problem, an equivalent is necessary (1 mg = 1000 mcg) to change 0.05 mg to 50 mcg (0.05 mg × 1000 = 50 mcg). Estimate the amount to give. Proportion (Fractions): 1 mL/100 mcg = x mL/50 mcg; 100 x = 50/100 = = 0.5 mL. The correct syringe to select for this injection is the 1 mL. Draw up 0.5 mL. The 3-mL syringe is used for a maximum volume of 3 mL of medication. Insulin syringes are used only for insulin administration, and the markings are in units. (Note: The 1-mL syringe is also called a precision or a tuberculin syringe. It is marked in milliliters to the nearest hundredth and in minims to the nearest half-minim.)
