The nurse is administering medications to several patients. Which action should the nurse take?

A) Advise a patient after a corticosteroid inhaler treatment to rinse mouth with water.
B) Administer an intravenous medication through tubing that is infusing blood.
C) Pinch up the deltoid muscle of an adult patient receiving a vaccination.
D) Aspirate before administering a subcutaneous injection in the abdomen.

If the patient uses a corticosteroid, have him or her rinse the mouth out with water or salt water or brush teeth after inhalation to reduce risk of fungal infection. Piercing a blood vessel during a subcutaneous injection is very rare. Therefore, aspiration is not necessary when administering subcutaneous injections. When giving immunizations to adults: to avoid injection into subcutaneous tissue, spread the skin of the selected vaccine administration site taut between the thumb and forefinger, isolating the muscle. Never administer IV medications through tubing that is infusing blood, blood products, or parenteral nutrition solutions.
