A nurse is contributing a nutritional plan of care for a child. Which of the following diagnostic tests should the nurse recommend for the child?

A. "Vaccinations, especially the MMR vaccine, have been proven to be a leading cause of autism in children." This statement is false. Extensive research has shown no link between vaccines, including the MMR vaccine, and autism. The original study suggesting a connection was discredited and retracted due to fraudulent data.

B. "ASD is primarily caused by poor parenting and a lack of nurturing in early childhood." This outdated theory, once known as the "refrigerator mother" hypothesis, has been debunked. Autism is a neurodevelopmental disorder with biological origins, not a result of parenting style.

C. "The exact causes of autism spectrum disorder are not fully understood, but it is believed to be related to a combination of genetic and environmental factors." This is correct. Research suggests that genetic predisposition, along with environmental influences (such as prenatal factors or advanced parental age), plays a role in ASD development. However, no single cause has been identified.

D. "ASD can be caused by consuming gluten and casein, which are found in wheat and dairy products, respectively." There is no scientific evidence that gluten or casein causes autism. While some parents report behavioral improvements on gluten-free or casein-free diets, these diets do not cause or cure autism.

A. Breathing techniques. Deep breathing exercises help reduce stress, promote relaxation, and lower anxiety, making them an effective strategy to mitigate burnout among healthcare staff.

B. Work extended shifts. Long shifts contribute to burnout by increasing physical and emotional exhaustion. Encouraging shorter shifts and adequate rest periods is more beneficial for staff well-being.

C. Facilitate discussion on vicarious trauma. Caring for terminally ill children can lead to compassion fatigue and secondary trauma. Providing a safe space for staff to discuss their experiences helps in processing emotions and reducing emotional distress.

D. Take sleep aids at night. While sleep is essential, relying on sleep aids is not a recommended long-term strategy for managing burnout. Encouraging healthy sleep hygiene and relaxation techniques is a safer approach.

E. Guided imagery. This stress-reduction technique involves visualizing calming and peaceful scenes, helping healthcare staff manage emotional strain and maintain resilience in a high-stress environment.
