Final answer:
To prevent sickle cell crisis in a preschool child with sickle cell disease, parents should notify the healthcare provider if a fever occurs, give penicillin as prescribed, and notify the healthcare provider if the child develops cold symptoms.
Step-by-step explanation:
The nurse should teach parents of a preschool child with sickle cell disease the following prevention methods:
- Notify the health care provider if a fever of 101.3°F or greater occurs: Since fever can indicate an infection, it is important to alert the healthcare provider to ensure prompt treatment.
- Give penicillin as prescribed: Penicillin helps prevent infections in children with sickle cell disease by reducing the risk of bacterial infections, which can trigger a sickle cell crisis.
- Notify the health care provider if your child begins to develop symptoms of a cold: Cold symptoms can indicate the start of an infection, which may lead to a crisis in children with sickle cell disease.
