Choice A:
Applying ice to the perineal area is not a recommended intervention for suspected placenta previa. While ice can help reduce swelling and pain in some cases, it does not address the underlying concern of potential placental bleeding.
Focusing on external monitoring for fetal well-being and avoiding any actions that could disrupt the placenta are the priorities in this situation.

Choice C:
Completing a vaginal exam is contraindicated in suspected placenta previa. Inserting fingers into the vagina can disrupt the placenta and potentially cause heavy bleeding, increasing the risk of preterm labor, fetal distress, or maternal hemorrhage. Non-invasive assessment methods are crucial to protect the placenta and prevent complications.

Choice D:
Performing a rectal exam is also not indicated for suspected placenta previa. It does not provide information about the placental position and could potentially stimulate contractions, which are undesirable in this situation.
External fetal monitoring is a safer and more informative approach.

Choice B:
Applying an external fetal monitor is the most appropriate action for a nurse caring for a client with suspected placenta previa. It allows for continuous assessment of fetal heart rate and activity, which can help detect any signs of fetal distress or placental abruption.
It is a non-invasive method that does not carry the risks associated with vaginal or rectal exams.
Early identification of any fetal compromise can lead to prompt interventions to ensure the best possible outcomes for both mother and baby.
