Answer :
Final answer:
The recommended cutoffs for when to consult a doctor about an infant's temperature are a temperature less than 97.7 °F or greater than 100 °F. These parameters are established because of the crucial role of body temperature as an essential vital sign that reflects the neonatal adjustments the infant makes post-birth, especially relating to thermoregulation.
Explanation:
The parameters for when parents should call the physician regarding an infant's temperature are when it falls less than 97.7 °F or rises greater than 100 °F (option d). The body temperature of an infant is an important vital sign and changes in temperature may suggest potential health issues. A lower than normal temperature could imply that the infant has difficulty in maintaining body warmth due to their immature regulatory systems and minimal subcutaneous fat. An elevated temperature, on the other hand, may signal an infection or other medical condition.
Significant fluctuations in body temperature outside of the normal range can be a cause for concern thus they must be checked and monitored persistently. The transition of infants from the womb to the outside world involves drastic respiratory and thermoregulatory adjustments, and deviations from the normal body temperature can suggest issues with these adjustments, which justify a call to the physician.
