A nurse in a provider's office is caring for a child who has a history of asthma. Which of the following findings should the nurse report to the provider?

Choice A reason: Assess the rest of the child's body for a rash.

The child's red marks across the cheeks are characteristic of fifth disease (also known as erythema infectiosum). Fifth disease is caused by parvovirus B19 and typically presents with a bright red rash on the cheeks, often referred to as "slapped cheek" appearance. The rash may eventually spread to other areas of the body, including the arms, trunk, thighs, and buttocks. It is usually mild and self-limiting.

Choice B reason: This option is not appropriate for a rash caused by fifth disease. There is no indication of child abuse or neglect.

Choice C reason: The rash is due to a viral infection and not related to trauma or injury. Questioning the parents is unnecessary.

Choice D reason: While assessing the child's temperature is important in general nursing care, it is not specifically related to the red marks on the cheeks in this case.

Choice A reason: This test measures the level of antibodies that the body produces against the streptolysin O enzyme, which is produced by some strains of streptococcal bacteria. A high level of ASO titer indicates that the child had a recent streptococcal infection, which may trigger rheumatic fever in some cases.

Choice B reason: This test does not directly indicate if the child has rheumatic fever. Rheumatic fever is a complication of untreated or inadequately treated streptococcal infection, which causes inflammation of the heart, joints, skin, and brain. The diagnosis of rheumatic fever is based on clinical criteria, such as the presence of carditis, polyarthritis, chorea, erythema marginatum, or subcutaneous nodules.

Choice C reason: This test does not confirm if the child has immunity to streptococcal bacteria. Immunity is the ability of the body to resist or fight off an infection. A high level of ASO titer does not mean that the child is immune to streptococcal bacteria, but rather that the child was exposed to them recently.

Choice D reason: This test does not indicate if the child has a therapeutic blood level of an aminoglycoside. Aminoglycosides are a class of antibiotics that are used to treat serious bacterial infections, such as endocarditis or septicemia. The blood level of an aminoglycoside is measured by a different test, called a peak and trough level, which determines the effectiveness and safety of the drug.
