A 7-year-old boy is brought to the pediatrician's office by his mother. The child reports a 1-day history of acute left foot pain. He had been playing with friends the previous day when he dropped a weight on his left foot. He was wearing shoes at the time. The foot has been tender for the past 24 hours, and it is now swollen (Figure 1). The child is not limping.
The patient's temperature is 36.6oC (97.80F); respiration rate is 20 breaths/min; pulse rate is 105 beats/min; and blood pressure is 111/76 mm Hg.
WHAT WOULD YOU DO NOW?
A. Observe the child for several days to see if the swelling and tenderness abate.
B. Order a plain x-ray film of the foot.
C. Order a complete blood cell (CBC) count.
D. Order plain x-ray films and a CBC count.
