Final answer:
The nurse should collect information about the child's reactions to previous hospitalizations before a tonsillectomy to help prevent potential complications during surgery and to understand how the child may cope with the procedure.
Step-by-step explanation:
Before a 5-year-old boy is admitted to the hospital to have his tonsils removed, it is essential for the nurse to collect specific information that is relevant to the upcoming procedure. Of the options provided, the correct information to collect would be D. Reactions to previous hospitalizations. This is important because knowing if the child has had any adverse reactions to medications or anesthesia in the past can help to prevent potential complications during the tonsillectomy. Prior experiences with hospitalization can also provide insight into how the child may cope with the stress of surgery and hospital stay. In contrast, the child's birth weight, the age at which he crawled, and whether he has had the measles do not directly pertain to the tonsillectomy procedure.
