A child sustains a fall at home and is brought to the hospital emergency department by the child's mother. After a radiographic examination, the child is determined to have a fractured arm, and a plaster cast is applied. The nurse provides instructions to the mother regarding neurocirculatory assessment and function. Which statement by the mother indicates a need for further instruction?
1. "I'll need to check her skin twice a day at the cast edges." 2. "If her hand gets real cool and pale, I can apply the heating pad to it." 3. "For the first couple of days, I should try to keep her hand higher than her heart most of the time, using pillows." 4. "If she seems way too fussy and her arm is painful even after I've given her the pain medication, it might be a problem, and I should call you for help to decide on what is happening."
