A nurse is reinforcing teaching about home safety with a client who is postpartum. Which of the following statements by the client indicates an understanding of the teaching?

Rationale: A. "I should use a firm mattress in my baby's crib.": A firm mattress reduces the risk of sudden infant death syndrome (SIDS) and suffocation by providing a stable, flat surface for safe infant sleep. This is a key recommendation in safe sleep guidelines. B. "I should set my hot water heater at 130 degrees Fahrenheit.": Setting the water heater at 130°F increases the risk of scald burns, especially for infants and young children. The recommended temperature to prevent burns is 120°F or lower. C. “I should use a crib with side rails that drop": Drop-side cribs have been banned due to safety concerns, including risk of entrapment and suffocation. Using a crib with fixed side rails is safer and recommended. D. "I should position my baby on their stomach to sleep during the day.": Placing infants on their stomach to sleep increases the risk of SIDS. The safest position for sleep is on the back, both during the day and night.
