A nurse teaches the parents of a 10-month-old infant about home safety. Which of the following information should the nurse include in the teaching? (Select all that apply.)

A. Serve food in small, non-circular pieces: Infants are at high risk for choking due to underdeveloped chewing skills. Serving food in small, irregular-shaped pieces reduces the chance of airway obstruction and promotes safe self-feeding as the infant learns to eat solids. B. Fit the mattress so that it is snug against the sides of the crib: A properly fitting crib mattress eliminates gaps that can trap an infant’s head or body, reducing the risk of suffocation or entrapment. This is a key for creating a safe sleep environment. C. Set the water heater at 65.6° C (150° F): This temperature is too high and increases the risk of scald burns. The water heater should be set to 48.9° C (120° F) or lower to protect infants from accidental hot water burns during bathing or handwashing. D. Install accordion style gates: Accordion-style gates pose a strangulation hazard due to the V-shaped openings and large gaps. Safety gates with vertical slats and no large openings are the recommended type for preventing falls while avoiding entrapment risks. E. Tie plastic bags in knots before discarding them: Tying plastic bags prevents infants from placing them over their heads, reducing the risk of suffocation. Even after being discarded, bags can pose a danger if left loose and accessible to crawling or curious infants.
