Final answer:
A toddler who is 36 inches tall has likely reached the maximum height for safe crib use, as they may be able to climb out and risk of injury.
Step-by-step explanation:
The question asks which toddler-age client has reached a height in which it is no longer safe to sleep in a crib. Looking at the height categories for toddlers, we can assess that the general safe limits for crib use are based on the potential for a child to climb out and risk falling. The heights in centimeters (cm) provided in Table 23.6.5 translate to approximately 28.5 inches to 38.5 inches for a healthy toddler between one and three years old. Considering the growth patterns and development milestones, a toddler who is 36 inches (or 91.4 cm) tall has most likely reached the maximum height considered safe for crib use, due to the ability to climb out and risk of injury.
