A nurse is caring for a client who is pregnant and is at the end of her first trimester. The nurse should place the Doppler ultrasound stethoscope in which of the following locations to begin assessing for the fetal heart tones (FHT)?

The correct answer is C.

A. Acrocyanosis of the extremities: Acrocyanosis, or blueness of the extremities, is a common finding in newborns and is usually considered normal. It often resolves on its own and doesn't typically require intervention.

B. Murmur at the left sternal border: It's not uncommon for newborns to have innocent murmurs, and many resolve on their own as the infant grows. A murmur at the left sternal border alone may not necessarily indicate a problem, but it should be assessed by a healthcare provider.

C. Substernal chest retractions while sleeping: Chest retractions can be a sign of respiratory distress, and intervention is needed to assess and address the cause. Substernal retractions suggest increased work of breathing and may indicate a respiratory issue that requires attention.

D. Positive Babinski reflex: The Babinski reflex is a normal neurological response in infants. It involves the toes fanning out when the sole of the foot is stroked. A positive Babinski reflex is expected in a 12-hour-old newborn and does not require intervention.

A. Frank breech position

A. In a frank breech presentation, the baby's buttocks are the presenting part. When the nurse locates fetal heart tones above the client's umbilicus at midline during active labor, it is indicative of a breech presentation, and the frank breech position is one possibility.

B. In a cephalic presentation, which is the most common and ideal position for childbirth, the fetal head is the presenting part, and the fetal heart tones would typically be heard below the umbilicus.

C. In a posterior position, the back of the baby's head is against the mother's spine. Fetal heart tones in this position would be typically heard below the umbilicus.

D. In a transverse lie, the baby is positioned horizontally across the uterus. Fetal heart tones may be heard laterally in this position, not necessarily above the umbilicus at midline.
