A nurse is evaluating an infant following a motor vehicle accident.

Which signs should the nurse monitor to detect increased intracranial pressure?

Choice A rationale
While an ASO titer test can be used in the diagnosis of rheumatic fever, it does not directly indicate if a child has rheumatic fever. Rheumatic fever is a complication that can occur after a streptococcal infection, and it involves multiple systems in the body, not just the presence of streptococcal antibodies.
Choice B rationale
An ASO titer test measures the antibodies produced by your body in response to a toxin known as streptolysin O, which is produced by group A Streptococcus (GAS) bacteria. Your body makes the antistreptolysin O antibodies when you have a strep infection caused by GAS bacteria. Therefore, a positive ASO titer test can confirm if your child had a recent streptococcal infection.
Choice C rationale
An ASO titer test does not measure the blood level of an aminoglycoside or any other therapeutic drug. Aminoglycosides are a class of antibiotics used to treat bacterial infections, and their levels in the blood are typically monitored with specific drug level tests, not an ASO titer.
Choice D rationale
An ASO titer test does not confirm if your child has immunity to streptococcal bacteria. The presence of ASO antibodies indicates a recent infection, but it does not provide information about the immune status or protection against future infections.

Choice A rationale
Depressed fontanels are not typically associated with increased intracranial pressure (ICP) in infants. In fact, bulging fontanels may be a sign of increased ICP1516.
Choice B rationale
A brisk pupillary reaction to light is not a specific sign of increased ICP in infants. Changes in pupillary reaction can occur in various conditions and are not definitive indicators of increased ICP.
Choice C rationale
Increased sleeping is a symptom of increased ICP in infants. However, this symptom alone is not enough to diagnose increased ICP as it can be seen in other conditions as well.
Choice D rationale
Unspecified symptom is not a valid choice as it does not provide a specific symptom to evaluate.
