A nurse in the emergency department is providing discharge teaching to a client who has a sprained ankle. Which of the following should the nurse include in the teaching?

Choice A reason: Maintaining the foot above the level of the head is excessive and not recommended. Elevation should be above the level of the heart to reduce swelling, not above the head. Choice B reason: Numbness and tingling are not expected after a sprain. These symptoms may indicate neurovascular compromise and should be reported immediately. Choice C reason: Applying ice for 20 min intervals is correct. Ice reduces swelling, inflammation, and pain by causing vasoconstriction. The 20-min interval prevents tissue damage from prolonged cold exposure. Choice D reason: Performing range of motion exercises immediately after injury is inappropriate. Rest is required during the acute phase to prevent further damage. ROM exercises are introduced later during rehabilitation.
