A nurse is caring for a newborn who was recently diagnosed with Tay-Sachs disease and observes the caregivers of the newborn crying in the room. Which of the following factors should the nurse identify as contributing to the caregivers' current emotional state?

A. Tay-Sachs disease is a progressive disease process with a maximum life span of 18 to 20 years: While this statement describes a serious progressive disease, it is inaccurate for Tay-Sachs, as the infantile form typically results in death much earlier, usually by 4–5 years of age, not late adolescence. B. Having Tay-Sachs disease means their child will never be able to have children of their own: Fertility is not a central concern in the infantile form of Tay-Sachs, and this factor is not a primary contributor to caregiver grief immediately after diagnosis. C. Having Tay-Sachs disease means their child cannot play sports due to possible heart conditions: Tay-Sachs does not primarily affect cardiac function; restrictions on activities like sports are not the main cause of caregiver distress in this context. D. Tay-Sachs is a progressive disease in which the child usually dies before years of age: The early-onset form of Tay-Sachs leads to progressive neurodegeneration, loss of motor and cognitive function, and death typically by 4–5 years. Awareness of this prognosis is a major factor contributing to the caregivers’ grief and emotional response.
