Final answer:
The nurse will obtain a subcutaneous needle and syringe when preparing to administer medroxyprogesterone acetate to a patient diagnosed with endometrial carcinoma.
Step-by-step explanation:
When preparing to administer medroxyprogesterone acetate to a patient diagnosed with endometrial carcinoma, the nurse will procure a subcutaneous needle and syringe. Medroxyprogesterone acetate is typically administered via subcutaneous injection, involving the introduction of the needle just beneath the skin. This route allows for the gradual absorption of the medication into the bloodstream, ensuring a sustained therapeutic effect. Subcutaneous injections are chosen for their convenience, ease of administration, and the ability to provide a controlled release of the drug. The nurse's skill in using the subcutaneous route contributes to the patient's comfort and facilitates the effective management of endometrial carcinoma.
