Which arterial blood gas result is most indicative that the intubated and mechanically ventilated patient is ready to have the ventilator rate weaned?

The nurse on the neurological intensive care unit would intervene if the provider attempted to assess the oculovestibular reflex in the patient with which recent injury?

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?
