A nurse is reinforcing teaching about home safety with the guardians of a toddler. Which of the following statements by a guardian indicates an understanding of the teaching?

A. “I can leave my child alone in the bathtub for up to 15 minutes after they learn to swim." Leaving a toddler alone in the bathtub is not safe, even if they know how to swim. Drowning occurs very quickly, and toddlers should always be supervised when in or near water. B. "Open windows are safe as long as the screens fit snugly." Even if the screens fit snugly, open windows still pose a risk of falls for toddlers. It is important to keep windows securely closed or use window guards to prevent accidents. C. "The water heater should be set to 120 degrees Fahrenheit or less." Setting the water heater to 120°F or lower is an appropriate and safe recommendation to prevent burns. Water temperatures higher than 120°F can cause serious burns, especially in young children. D. “I will tell my toddler to never touch a firearm." Simply telling a toddler to avoid firearms may not be enough. Firearms should be securely stored in a locked, childproof safe, away from the child's reach, regardless of what the child is told.
