A nurse is assessing a newborn who is 12 hr old. Which of the following manifestations requires intervention by the nurse?

Acrocyanosis of the extremities

Murmur at the left sternal border

Substernal chest retractions while sleeping

Positive Babinski reflex

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is B

Explanation

A. Contractions that last 45 seconds each with a 3-minute rest between contractions are less common. Typically, contractions last around 60 seconds during active labor.

B. Contractions that last for 60 seconds each with a 3-min rest between contractions is the expected pattern.

During active labor, contractions are commonly around 60 seconds in duration, and they occur approximately every 4-5 minutes.

C. Contractions that last for 60 seconds each with a 4-min rest between contractions are not consistent with the usual pattern of contractions in active labor. A 4-minute rest between contractions would be an extended interval.

D. A contraction that lasts for 4 minutes followed by a period of relaxation is not typical and may indicate a problem. Normal contractions usually last around 60 seconds or less.

A. "This medication will stop your labor" B. "This medication stimulates fetal lung maturity" C. "This medication will decrease your risk for uterine infections" D. "This medication will increase your baby's weight"

Correct Answer is B

Explanation

A. "This medication will stop your labor": Betamethasone is not intended to stop labor. It is given to promote fetal lung maturity and reduce the risk of complications associated with preterm birth.

B. "This medication stimulates fetal lung maturity": This is the correct statement. Betamethasone is administered to enhance the production of surfactant in the fetal lungs, improving respiratory outcomes for the preterm infant.

C. "This medication will decrease your risk for uterine infections": Betamethasone does not directly decrease the risk of uterine infections. Its primary benefit is in promoting fetal lung maturity.

D. "This medication will increase your baby's weight": Betamethasone is not given to increase the baby's weight. Its main focus is on improving lung function and reducing respiratory complications in preterm infants.
