The nurse is preparing to give a heparin injection to a client who is malnourished and cachectic. A subcutaneous method of injection would be appropriate for so.
The nurse should dispense subcutaneous injections at 90 degrees if 2 in (5 cm) of subcutaneous tissue can be grasped, or at 45 degrees if only 1 in (2.5 cm) can be grasped. Anticoagulants are best absorbed if administered in the abdomen at least 2 in (5 cm) away from the umbilicus.
Intramuscular injection of heparin would drive quick absorption, resulting in a hematoma and agonizing muscle irritation. It should only be injected into the abdomen, the outer thigh, the buttocks, or the outer upper arm.
