A nurse in a mental health clinic is assessing a client who was brought in by her adult daughter stating that her mother has not been able to leave her home for weeks because she is afraid to be outdoors alone. The nurse should anticipate planning care for managing which of the following phobias?

A. Mysophobia is the fear of germs or contamination, which does not align with the client's fear of being outdoors alone. B. Xenophobia is the fear of strangers or foreigners, which is unrelated to the client's fear of being outside alone. C. Agoraphobia is the fear of being in situations where escape might be difficult or help unavailable, often resulting in an inability to leave the home. This matches the client's symptoms of being afraid to go outdoors alone. D. Acrophobia is the fear of heights, which is not relevant to the client's fear of leaving her home.
