Which of the following statements best conveys the rationale for this careful examination?
A) The immature hypothalamus is unable to perform normal thermoregulation.
B) Infants are susceptible to serious infections because of their decreased immune function.
C) Commonly used antipyretics often have no effect on the core temperature of infants.
D) Fever in neonates is often evidence of a congenital disorder rather than an infection.
Ans: B
Feedback:
Younger children have decreased immunologic function and are more commonly infected with virulent organisms. Neonates are at particularly high risk for serious bacterial infections that can cause bacteremia or meningitis. Neonates are capable of thermoregulation, and fever is not necessarily indicative of a congenital disorder. Antipyretics are effective in the treatment of fever in infants.
