A nurse is caring for a child who was admitted with suspected rheumatic fever. The provider prescribes an antistreptolysin O (ASO) titer. The parent asks the nurse about the purpose of the test. Which of the following responses should the nurse make?

The correct answer is a. Measles, mumps, rubella (MMR) and d. Varicella (VAR).

Choice A reason:

Measles, mumps, rubella (MMR): The MMR vaccine is recommended for children at 12-15 months of age. It protects against three serious diseases: measles, mumps, and rubella. The first dose is typically given at 12-15 months, with a second dose at 4-6 years. Measles can cause severe complications such as pneumonia and encephalitis. Mumps can lead to meningitis and hearing loss, while rubella can cause congenital rubella syndrome in pregnant women. Administering the MMR vaccine at the recommended age ensures that the child is protected from these potentially severe diseases.

Choice B reason:

Rotavirus (RV): This vaccine is given to infants at 2, 4, and possibly 6 months of age. It is not typically administered to a 1-year-old child as the series should be completed by 8 months. Rotavirus is a leading cause of severe diarrhea and dehydration in infants and young children. The vaccine is given orally and is highly effective in preventing rotavirus gastroenteritis. However, since the vaccine series is completed by 8 months, it is not appropriate for a 1-year-old child.

Choice C reason:

Human papillomavirus (HPV4): The HPV vaccine is recommended starting at 11-12 years of age. It is not suitable for a 1-year-old child. HPV is a common virus that can lead to certain types of cancers, including cervical cancer. The vaccine is most effective when given before exposure to HPV, which is why it is recommended for preteens. Administering the HPV vaccine to a 1-year-old would not be appropriate as it is not within the recommended age range.

Choice D reason:

Varicella (VAR): The VAR vaccine is recommended for children at 12-15 months of age to protect against chickenpox. A second dose is given at 4-6 years. Chickenpox can cause an itchy rash, fever, and tiredness. In some cases, it can lead to severe skin infections, pneumonia, and encephalitis. Vaccinating at the recommended age ensures that the child is protected from these complications. The first dose at 12-15 months is crucial for building immunity against the varicella virus.

Choice E reason:

Diphtheria, tetanus and acellular pertussis (DTaP): The DTaP vaccine is given in a series of five doses at 2, 4, 6, 15-18 months, and 4-6 years. The 4th dose is given at 15-18 months, not at 1 year. DTaP protects against three serious diseases: diphtheria, which can cause breathing problems and heart failure; tetanus, which causes painful muscle stiffness; and pertussis (whooping cough), which can lead to severe coughing spells and pneumonia. The timing of the doses is crucial for ensuring effective immunity, and the 1-year mark is not one of the recommended times for the DTaP vaccine.

Choice A: Reducing environmental stimuli can help decrease the discomfort and agitation of a child who has meningitis, as they may experience headache, photophobia, and neck stiffness. However, this action is not the priority, as it does not address the cause of the infection or prevent complications.

Choice B: Documenting intake and output can help monitor the fluid balance and hydration status of a child who has meningitis, as they may have fever, vomiting, and decreased oral intake. However, this action is not the priority, as it does not address the cause of the infection or prevent complications.

Choice C: Administering antibiotics when available can help treat the bacterial infection that causes meningitis and prevent serious complications such as brain damage, hearing loss, or death. This action is the priority, as it can save the child's life and improve their outcome.

Choice D: Maintaining seizure precautions can help protect the child from injury and provide safety measures in case of a seizure, as meningitis can cause increased intracranial pressure and seizures. However, this action is not the priority, as it does not address the cause of the infection or prevent complications.
