2. During flight transport of a postpartum patient with uterine atony unresponsive to oxytocin, which second-line uterotonic is CONTRAINDICATED in a patient with asthma?

Exposed bowel in gastroschisis must be kept moist and warm with saline-moistened gauze and covered with plastic wrap or a bowel bag to prevent heat and fluid loss.
5. Which flight physiology principle explains why sinusitis or ear pain may worsen during aircraft descent?
During descent, atmospheric pressure rises and gas in blocked sinuses or middle ear cannot equalize, compressing trapped air and causing pain or barotrauma.
6. During air transport, a patient develops a wide-complex tachycardia at 180 bpm with a pulse. The patient is hemodynamically stable. What is the most appropriate initial intervention?
