A Pediatric Nurse, Who Has Worked on the Inpatient Unit

A pediatric nurse, who has worked on the inpatient unit for 7 years, is enrolled in a master's program. The nurse notes that children who are homeless and who are admitted to the inpatient setting seem to have longer lengths of hospital stay, appear to have poorer verbal skills, and seem to be more fearful of separation from their parents. The nurse designs a study to measure these variables in homeless children, and to compare the findings with the average patients on the same unit. What is the research question?

A) Are longer hospital stays, poorer verbal skills, and increased fear of separation from parents made worse by children's homelessness?
B) Does children's homelessness affect length of hospital stay, verbal skills, and fear of separation from parents?
C) Was homelessness related to length of hospital stay, verbal skills, and fear of separation from parents in this study?
D) Is homelessness in children related to length of hospital stay, verbal skills, and fear of separation from parents?
