A 3-year-old male was brought into the emergency room this morning with a sudden onset of 'fast and noisy breathing'. According to his parents, he had sneezing and a runny nose last week but seemed to have recovered. The child lives with 2 older, school-age siblings, his parents, and 3 dogs. He was born at 37 weeks' gestation. The parents deny smoking, but his grandmother cares for him in the afternoons and smokes outside when she is at the house. He has no significant medical history. He has received all vaccines except for those due at 3 years. Upon exam, the child is? Which two items must the nurse ensure are available before attempting to place the intravenous line?
