A public health nurse is caring for a group of clients who experienced mold exposure in their home environment. Which of the following clients should the nurse identify as at risk for adverse effects of mold overgrowth?

Rationale: A. A client who has dementia: Dementia affects cognitive function but does not inherently increase susceptibility to respiratory complications from mold exposure. While general health monitoring is important, this client is not at high risk for mold-related adverse effects. B. A client who has osteoarthritis: Osteoarthritis primarily affects joints and mobility. It does not compromise the respiratory system or immune response in a way that would increase vulnerability to mold exposure. C. A client who has cystic fibrosis: Clients with cystic fibrosis have impaired mucociliary clearance and chronic respiratory vulnerability, making them more susceptible to respiratory infections and complications from environmental mold exposure. Mold inhalation can exacerbate pulmonary symptoms and lead to significant health risks. D. A client who has chronic hypertension: Hypertension affects the cardiovascular system but does not directly increase susceptibility to respiratory complications from mold. This client is not considered high risk for adverse effects from mold exposure.
