A client at 6-weeks gestation presents to the office with a report of vaginal bleeding for the last 12 hours without cramping. Which action should the nurse take?

Choice A reason: Verifying the last menstrual cycle helps estimate gestational age but does not directly assess the current pregnancy status or cause of bleeding, which requires a more immediate diagnostic approach. Choice B reason: Checking serum human chorionic gonadotropin levels quantitatively confirms pregnancy viability and detects abnormalities like miscarriage or ectopic pregnancy, critical for evaluating vaginal bleeding at 6 weeks gestation. Choice C reason: Inquiring about the last intercourse provides context for pregnancy timing but offers no diagnostic insight into the bleeding’s cause, which needs objective hormonal or imaging assessment instead. Choice D reason: Repeating a urine pregnancy test confirms pregnancy but lacks the precision of serum hCG to assess viability or progression, making it less useful for bleeding evaluation.
