After teaching a pregnant client about potential complications of amniocentesis that must be reported immediately, the nurse determines that the client understands the instruction when she says that she will report:

• A. Mild uterine cramping.
• B. Abdominal tenderness.
• C. Low-grade fever.
• D. Vaginal bleeding.

Answer: (D)

Postamniocentesis, the most urgent red flag is vaginal bleeding because it can signal placental injury or placental abruption and potential miscarriage, which require immediate evaluation and monitoring. While mild uterine cramping or abdominal tenderness can occur as a normal postprocedure sensation, they don’t by themselves indicate an acute emergency. A low-grade fever may warrant prompt assessment for infection, but it’s the new or heavy vaginal bleeding that most directly signals a serious complication that needs rapid medical attention. If bleeding occurs, the patient should seek care right away to assess maternal and fetal status.
