The nurse is assessing a 38-week gestation newborn infant immediately following a vaginal birth. Which assessment finding best indicates that the infant is transitioning well to extrauterine life?

A. Cries vigorously when stimulated:
Explanation: Vigorous crying is a positive sign in a newborn. It indicates that the baby is responsive, breathing effectively, and is capable of establishing the necessary air exchange.

B. A positive Babinski reflex:
Explanation: The Babinski reflex is a normal reflex in infants where the toes spread out when the sole of the foot is stimulated. While it is a normal reflex in newborns, it might not necessarily indicate the immediate transition to extrauterine life.

C. Heart rate of 220 beats/minute:
Explanation: A heart rate of 220 beats per minute in a newborn is higher than the normal range. It could be a sign of tachycardia, and this finding might require further evaluation by healthcare providers.

D. Flexion of all four extremities:
Explanation: Flexion of extremities is a normal response in a newborn, but it might not specifically indicate successful transition. It's a common response seen in healthy newborns.

A. Cleanse the spinal injection site:
Cleansing the spinal injection site is a routine part of maintaining proper hygiene during and after the administration of spinal anesthesia. However, if the client is experiencing symptoms of a spinal headache, the priority is to prepare for potential interventions by having the necessary equipment ready rather than focusing on the site itself.

B. Apply an abdominal binder:
Applying an abdominal binder is not directly related to addressing a spinal headache. Abdominal binders are typically used for providing support to the abdominal muscles after childbirth or surgery. It wouldn't be the primary intervention for a spinal headache.

C. Insert an indwelling Foley catheter:
Inserting an indwelling Foley catheter is not a direct intervention for addressing a spinal headache. Spinal headaches are related to cerebrospinal fluid leakage and positioning. While managing the patient's overall care is important, it may not be the immediate priority in this context.

D. Place procedure equipment at bedside:
This is the most appropriate action in the context of a postpartal client exhibiting symptoms of a spinal headache. Having the necessary procedure equipment, such as materials for a blood patch, ready at the bedside ensures preparedness for potential interventions by the anesthesiologist.
