Final answer:
The nurse can alleviate the mother's concern about her child's bed-wetting post-admission to the hospital by explaining that stress can cause temporary regression in young children (option c). A gentle and understanding approach, emphasizing patience and support, is recommended during this adjustment period. Setbacks in developmental milestones such as potty training are normal and not typically a cause for concern.
Step-by-step explanation:
The concern regarding a 2-year-old child who was previously potty-trained and begins to wet the bed after admission to a hospital is understandable. To allay anxiety, it's important to provide reassurance and a professional explanation to the mother. The nurse can comfort the mother by stating, "The stress of hospitalization makes children regress a little." This acknowledges the common behavior in young children to temporarily revert to earlier behaviors under stress, such as a hospital stay. Regressive behaviors are often a child's response to the pressures of a new and potentially frightening environment.
It is crucial to remain patient and supportive as children readjust back to their previous level of development after the stress has been alleviated. The normative approach to child development indicates that occasional setbacks in milestones like toilet training are temporary and no cause for alarm.
Hence, the answer is option c.
