NCLEX-PN® ExaminationPharmacological TherapiesMedium
An LPN is preparing to administer a subcutaneous injection of enoxaparin. The client has a BMI of 32. Which site is most appropriate for this injection?
- ADeltoid muscle
- BAbdomen, at least 2 inches from the umbilicus
- COuter aspect of the upper arm
- DVentrogluteal area
Show answer & explanationAnswer & explanation
Correct answer: B. Abdomen, at least 2 inches from the umbilicus
The abdomen, specifically the area at least 2 inches from the umbilicus, is the preferred site for subcutaneous injections of enoxaparin and other anticoagulants. This site has a good fat pad and allows for consistent absorption, especially in clients with higher BMIs.
Why the other options are wrong
- A. The deltoid is typically used for intramuscular injections, not subcutaneous, and has less subcutaneous tissue.
- C. The outer aspect of the upper arm can be used for some subcutaneous injections, but the abdomen is generally preferred for anticoagulants like enoxaparin due to better absorption and reduced risk of hematoma.
- D. The ventrogluteal area is a common site for intramuscular injections, not subcutaneous.
Enoxaparin Subcutaneous Injection
Administration of the anticoagulant enoxaparin via the subcutaneous route to prevent or treat thromboembolic disorders.
- Preferred site: abdomen.
- Inject 2 inches from umbilicus.
- Do not expel air bubble from pre-filled syringe.
