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?
"This test will indicate if your child has rheumatic fever."
"This test will confirm if your child had a recent streptococcal infection."
"This test will indicate if your child has a therapeutic blood level of an aminoglycoside."
"This test will confirm if your child has immunity to streptococcal bacteria."
The Correct Answer is B
Choice A: This test will not indicate if the child has rheumatic fever, as rheumatic fever is a complication of an untreated or inadequately treated streptococcal infection that affects the heart, joints, skin, and brain. Rheumatic fever is diagnosed based on clinical criteria, such as carditis, polyarthritis, chorea, erythema marginatum, and subcutaneous nodules.
Choice B: This test will confirm if the child had a recent streptococcal infection, as antistreptolysin O (ASO) is an antibody that the body produces in response to streptococcal bacteria. A high ASO titer indicates that the child was exposed to streptococcal bacteria within the past few weeks. A streptococcal infection can cause pharyngitis, tonsillitis, scarlet fever, or impetigo.
Choice C: This test will not indicate if the child has a therapeutic blood level of an aminoglycoside, as an aminoglycoside is a type of antibiotic that is used to treat serious bacterial infections. A therapeutic blood level of an aminoglycoside means that the drug is effective and safe in the body. A therapeutic blood level of an aminoglycoside is measured by a peak and trough level.
Choice D: This test will not confirm if the child has immunity to streptococcal bacteria, as immunity to streptococcal bacteria means that the body can resist or fight the infection. Immunity to streptococcal bacteria can be acquired by natural exposure or vaccination. Immunity to streptococcal bacteria is measured by an antibody titer or a skin test.

Correct Answer is C
Explanation
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.

A 3-year-old child can also walk down stairs placing both feet on each step with one hand held by an adult.
Choice B: A 4-year-old child is developmentally able to descend stairs by placing both feet on each step and holding on to the railing. A 4-year-old child can also walk up stairs alternating feet without assistance.
Choice C: A 5-year-old child is developmentally more advanced than descending stairs by placing both feet on each step and holding on to the railing. A 5-year-old child can walk up and down stairs alternating feet without assistance.
Choice D: A 6-year-old child is developmentally more advanced than descending stairs by placing both feet on each step and holding on to the railing. A 6-year-old child can walk up and down stairs alternating feet without assistance and can also hop and skip on one foot.
