A nurse is caring for a client who is at 37 weeks of gestation and has placenta previa.The client asks the nurse why the provider does not do an internal examination.Which of the following explanations of the primary reason should the nurse provide?

Choice A rationaleWhile the risk of infection is always a concern with internal examinations, it is not the primary reason to avoid them in a client with placenta previa. The placenta's abnormal placement already creates a significant barrier, making direct introduction of bacteria during a gentle examination less of an immediate threat compared to hemorrhage. Standard sterile techniques further mitigate this risk.Choice B rationaleIn placenta previa, the placenta is implanted in the lower uterine segment, potentially covering or being very close to the cervical os. An internal examination could disrupt the placenta, leading to significant bleeding. The highly vascular nature of the placenta means any tearing or separation can result in rapid and profound hemorrhage, endangering both the mother and the fetus.Choice C rationaleWhile internal examinations can slightly increase the risk of membrane rupture in any pregnant client, this is not the primary concern in placenta previa. The main danger lies in the potential for placental disruption and subsequent hemorrhage due to the placenta's low-lying position relative to the cervix.Choice D rationaleAlthough cervical manipulation during an internal examination can sometimes stimulate uterine contractions and potentially lead to preterm labor, the more immediate and critical risk in a client with placenta previa is hemorrhage. The priority is to avoid any action that could disrupt the placenta and cause severe bleeding.
