A nurse is reviewing the medical records of several children in an outpatient clinic. The nurse should identify that which of the following infections is included on the list of nationally notifiable conditions?

A: By the age of 7, most children have a grasp of days and dates as part of their routine. However, not being able to verbalize the date does not necessarily indicate a developmental delay, as it could be related to the child's learning environment or educational opportunities.

B: Counting backwards is a skill that develops with age and practice. A 7-year-old may struggle with this task due to various reasons such as lack of practice, but it is not a definitive sign of a developmental delay.

C: Making change involves complex cognitive skills including math, understanding of money value, and transactions, which may still be developing in a 7-year-old. This skill varies widely among children and is influenced by their experiences with money.

D: The ability to distinguish right from left is a developmental milestone typically achieved by the age of 5 to 6 years. Persistent difficulty in telling the difference between right and left at the age of 7 could suggest a developmental delay in spatial awareness.

Rationale:

A) Insomnia is a sleep disorder and is not typically associated with head injuries unless there is a concurrent neurological complication.

B) Irritability can be a sign of increased intracranial pressure following a head injury and should be promptly reported for further evaluation.

C) Diarrhea is not a common manifestation of head injuries and would not typically be included in monitoring and reporting instructions.

D) Hypothermia is not typically associated with head injuries unless there is a severe injury with shock, and it is not a common manifestation requiring monitoring in the acute phase of head injury.
