A nurse is caring for a client who is postpartum, has a deep-vein thrombosis, and is receiving heparin therapy via subcutaneous injections.Which of the following actions should the nurse take?

Choice A rationaleAspirin is contraindicated in clients receiving heparin therapy due to additive anticoagulant effects, which significantly increase the risk of bleeding complications such as hematomas or internal bleeding.Choice B rationaleMassaging the injection site can increase the risk of local bleeding or bruising at the site of heparin administration, making this practice unsafe and ineffective for anticoagulant therapy.Choice C rationaleBreastfeeding is not contraindicated while receiving heparin therapy. Heparin does not significantly transfer into breast milk or harm the neonate, so nursing remains safe during treatment.Choice D rationaleThe abdomen is the preferred site for subcutaneous heparin injections due to its fatty tissue, which minimizes risks of intramuscular bleeding and ensures consistent drug absorption.
