Final answer:
The clinic nurse will administer the DTaP and IPV vaccines to the child.
Step-by-step explanation:
The clinic nurse will expect to administer the DTaP vaccine and the IPV vaccine to the 4 1/2-year-old child who has been receiving high-dose systemic glucocorticoids for several months. The DTaP vaccine protects against diphtheria, tetanus, and pertussis, while the IPV vaccine protects against polio. These vaccines are important to prevent these diseases in children, especially those on high-dose glucocorticoids which can weaken the immune system.
