What should the nurse instruct a parent of a 3-month-old infant regarding accident prevention?

The emphasis on the importance of testing the temperature of water before bathing an infant is crucial for preventing scalding injuries. An infant's skin is much more sensitive than that of an older child or an adult, and they can sustain serious burns from water that is even moderately hot. By ensuring that the water temperature is safe—ideally below 120°F (49°C)—the nurse helps the parent protect the child from potential harm during bath time, which is a common activity that requires vigilance.

Other measures, such as removing small objects, covering electric outlets, and removing toxic substances, are certainly important for a child’s safety. However, the risk of immediate injury from hot water during a bath is particularly pertinent for an infant, making temperature testing a top priority in accident prevention.
