When applying cold packs to a patient with a right ankle sprain, the nurse should:
A) Apply it immediately after the injury occurs.
B) Use sterile technique.
C) Secure the cooling device with pins so that the device doesn't fall off.
D) Discontinue any application longer than 3 hours.
Ans: A
Feedback: Applying cold packs immediately minimizes edema. Sterile technique is required only when applying cold packs to any open wound or when applying cold applications to the eyes. Cooling devices are not secured with pins because an accidental puncture could allow cold fluids to leak out and burn the patient's skin. Cold packs shouldn't be left on for longer than 1 hour at a time because of the risk of reflexive vasodilation.
