A nurse is caring for a school-age child who has a new plaster cast on her right arm. Which of the following actions should the nurse take?

A. Low-pitched cry: A high-pitched cry, not a low-pitched one, is more typical of increased ICP in infants. A low-pitched cry is not a common sign of ICP and may be more related to other conditions.

B. Positive Babinski reflex: The Babinski reflex is normal in infants up to about 1 year of age and is not indicative of increased ICP. It is a normal finding and not specific to increased intracranial pressure.

C. Insomnia: Infants with increased ICP may exhibit irritability and changes in sleeping patterns, but insomnia (difficulty sleeping) is not a classic symptom. The focus should be on other more specific signs like changes in cry and physical appearance.

D. Bulging fontanel: A bulging fontanel is a key sign of increased ICP in infants. It occurs due to pressure within the skull causing the soft spot on the head to protrude. This is a classic symptom of increased intracranial pressure in infants.

A. "I'll give him acetaminophen for the pain.": Acetaminophen is used for pain relief and fever reduction but does not address disease transmission. It does not prevent the spread of the streptococcal infection.

B. "I'll discard his toothbrush and buy another.": This is crucial because the streptococcal bacteria can remain on the toothbrush, leading to potential reinfection or spreading the bacteria to others. Replacing the toothbrush after starting antibiotics helps to reduce the risk of reinfection.

C. "I'll continue to encourage him to drink lots of fluids.": Staying hydrated is important for recovery, but it does not prevent the transmission of the infection.

D. "I'll take his temperature every 4 hours.": Monitoring temperature helps track the child’s condition but does not prevent the spread of the infection.
