The ointment should be applied in a thin layer and left to absorb into the skin.Choice C rationale:Applying the ointment in a thick layer is not recommended. A thin, uniform layer is sufficient for therapeutic effect.Choice D rationale:Covering the administration area with plastic wrap is the correct action. This helps to keep the ointment in place and enhances absorption.
