A nurse is counseling a group of clients from a town that was affected by a hurricane 6 months ago. For which of the following clients should the nurse initiate a referral to assess for the presence of post-traumatic stress disorder? (Select all that apply)

Choice A reason: Occasional mild nausea is common in early pregnancy due to hormonal changes and does not typically require reporting unless severe or persistent. It is not a concerning finding at 14 weeks, so this is incorrect for urgent reporting.
Choice B reason: Mild ankle swelling in the evening can be normal due to fluid retention but is not urgent unless accompanied by other preeclampsia signs. It is less critical than bleeding, so this is incorrect for priority reporting.
Choice C reason: Vaginal bleeding at 14 weeks is abnormal and may indicate miscarriage, placental issues, or other complications, requiring immediate reporting to the provider for evaluation. This finding is critical at 14 weeks gestation, aligning with obstetric emergency protocols, making it the correct choice for teaching.
Choice D reason: Increased appetite is normal in pregnancy as nutritional needs rise and does not warrant urgent reporting. It reflects healthy adaptation rather than a complication, so this is incorrect for inclusion in teaching about concerning findings.

Choice A reason: Varicella, a viral infection, is not treated with antibiotics, which target bacteria. Returning to school after 24 hours of antibiotics is incorrect, as contagiousness persists until lesions crust, typically 5-7 days, risking transmission if the child returns prematurely.
Choice B reason: A negative titer result indicates immunity or resolved infection but is not a practical criterion for school return. Varicella contagiousness depends on lesion crusting, not serology, which is complex and unnecessary when clinical signs confirm reduced infectivity in affected children.
Choice C reason: Fever subsidence does not ensure non-contagiousness in Varicella. The virus spreads via respiratory droplets and lesions until crusted. Allowing return based on fever ignores transmission risk, as active lesions remain infectious, potentially spreading the virus in school settings.
Choice D reason: Varicella is contagious until lesions crust over, typically 5-7 days post-rash. Crusting indicates the end of viral shedding, ensuring safety for school return. This aligns with infection control guidelines, preventing transmission via contact or respiratory routes in communal settings.
