A nurse is preparing to administer immunizations to a 4-year-old child who is currently up to date with the recommended immunization schedule.Which of the following immunizations should the nurse plan to administer? (Select all that apply)

Choice A rationaleDiphtheria, tetanus, and acellular pertussis (DTaP) vaccine is typically administered to children to protect them against three serious diseases. Diphtheria and tetanus are bacterial infections that can cause severe health problems, including difficulty breathing, heart failure, paralysis, and death. The acellular pertussis component protects against whooping cough, a highly contagious respiratory disease that can be especially dangerous for infants and young children. The DTaP vaccine is part of the recommended immunization schedule for children and is given in multiple doses throughout early childhood to ensure ongoing immunity against these diseases.Choice B rationaleThe measles, mumps, and rubella (MMR) vaccine is crucial for preventing three viral infections. Measles is a highly contagious virus that can lead to serious complications such as pneumonia, encephalitis, and death. Mumps can cause swelling of the salivary glands, meningitis, and orchitis, which can lead to infertility. Rubella, also known as German measles, is particularly dangerous for pregnant women as it can cause congenital rubella syndrome in the developing fetus, leading to serious birth defects. The MMR vaccine is administered to children to ensure they develop immunity to these viruses and prevent outbreaks.Choice C rationaleThe varicella (VAR) vaccine protects against chickenpox, a highly contagious viral infection caused by the varicella-zoster virus. Chickenpox can cause an itchy rash, fever, and tiredness, and although it is usually mild in children, it can lead to serious complications such as pneumonia, encephalitis, and bacterial infections of the skin. Vaccination with VAR is important to prevent the spread of chickenpox and to protect individuals from severe illness and complications. The VAR vaccine is part of the recommended immunization schedule for children and is given in two doses to ensure effective immunity.Choice D rationaleThe rotavirus (RV) vaccine protects against rotavirus infections, which are a leading cause of severe diarrhea and dehydration in infants and young children. Rotavirus can cause severe gastroenteritis, leading to hospitalizations and even death in severe cases. The RV vaccine is administered orally in multiple doses during infancy to prevent rotavirus infections and reduce the incidence of severe diarrhea and its associated complications. However, by the age of 4, children typically have already completed the RV vaccine series, which is why it is not included in the immunizations for a 4-year-old who is up to date.
