Final answer:
To manage a pregnant passenger at 35 weeks gestation who experiences weakness and lightheadedness on a flight, initially ensure comfortable seating and check vital signs, offer hydration or a sweet drink, and provide reassurance.
Step-by-step explanation:
A 32-year-old female at 35 weeks gestation is evaluated during a domestic airline flight for an episode of weakness and lightheadedness. The most appropriate next step in management would be to ensure she is sitting comfortably, possibly with her feet up to improve circulation. It's essential to check her vital signs, including her blood pressure and pulse, and look for any signs of dehydration or hypoglycemia, which can occur during pregnancy and may cause these symptoms. Providing her with water or a sweet drink, and reassurance, can be helpful. If these measures do not resolve the symptoms, or if they worsen, additional medical evaluation may be warranted owing to the potential for complications from preterm labor or other pregnancy-related conditions.
