While performing culdocentesis in female patient ,needle should be most efficiently inseed through which of the following structures ?: (A) Anterior fornix of the vagina, (B) Posterior fornix of the vagina, (C) Anterior wall of the rectum, (D) Posterior wall of the uterine body
Answer is B. A needle should be inseed through the posterior fornix, just below the posterior lip of cervix while the patient is in supine position, to aspirate abnormal fluid i the cul-de-sac of Douglas(rectouterine pouch). Rectouterine excavation is not most efficiently aspirated by puncture of other structures.
