While collecting data from a client who has a cast on his right leg, a nurse locates an area on the cast that feels warm to the touch. The nurse also notices an odor in the area of the cast. Which of the following findings should the nurse identify as a complication to the client's condition?

A. Infection: Rationale: Warmth and odor from a cast site can indicate an infection beneath the cast, possibly from a skin wound or pressure ulcer. B. Poor circulation: Rationale: This would be evidenced by coolness, pallor, or weak pulses, not warmth and odor. C. Uneven cast drying: Rationale: This may make the cast feel warm, but would not produce odor or persist days after application. D. Pressure from the cast: Rationale: May cause pain or numbness, but not usually warmth and odor. Infection is more likely with these signs.
