Determine the Cᴇᴏ₂ (cerebral oxygen extraction) for the patient receiving 100% FiO₂ whose jugular vein oximetry reads 54% and the peripheral pulse oximetry reads 92%. Input your answer using a whole number.

The 5-day-old 38-week-gestation neonate was born to a 25-year-old primigravida woman after a pregnancy and vacuum-assisted delivery complicated by gestational diabetes, large for gestational age fetus, and shoulder dystocia. The neonate required vigorous stimulation and positive pressure ventilation. Apgar scores were 3 and 8 at 1 and 5 minutes of life. At the pediatrician’s appointment after discharge, the neonate is found to have a large bruise at the back of the head that was sustained during birth and eyes glued shut with yellow, mucopurulent discharge. A gram stain of the drainage reveals gram-negative cocci in pairs. The mother states, “No matter what I do, it keeps coming back. I’ve used warm compresses and washed it away.” Additionally, the mother reports the infant is breastfeeding well with 4 wet diapers and 1 stool per day. The nurse informs the provider of the assessment and requests which order first?
