Which should cause a nurse to suspect that an infection has developed under a cast?
a. Complaint of paresthesia
b. Cold toes
c. Increased respirations
d. "Hot spots" felt on cast surface
ANS: D
If hot spots are felt on the cast surface, they usually indicate infection beneath the area. This should be reported so that a window can be made in the cast to observe the site. The five Ps of ischemia from a vascular injury are pain, pallor, pulselessness, paresthesia, and paralysis. Paresthesia is an indication of vascular injury, not infection. Cold toes may be indicative of too tight a cast and need further evaluation. Increased respirations may be indicative of a respiratory tract infection or pulmonary emboli. This should be reported, and child should be evaluated.
