A nurse has been assigned to an internal disaster drill team and is triaging clients. Which of the following clients should the nurse classify with a green tag?

Choice A reason: Applying nitroglycerin ointment in a thin, even layer ensures consistent absorption for angina relief, as specified by dosing guidelines (e.g., using a dosing paper). This maximizes efficacy and minimizes side effects like hypotension, aligning with manufacturer instructions, making it the correct teaching point.
Choice B reason: Applying to the forearm is not standard, as nitroglycerin ointment is typically applied to the chest, upper arm, or back for optimal absorption. Forearm application may reduce effectiveness due to skin thickness, making this an incorrect site choice.
Choice C reason: Applying every 4 hours is incorrect, as nitroglycerin ointment is typically applied 2-3 times daily, with a 12-hour nitrate-free interval to prevent tolerance. This frequency is too frequent and risks side effects, making it an inaccurate instruction.
Choice D reason: Massaging nitroglycerin ointment into the skin is contraindicated, as it alters absorption rates and may cause inconsistent dosing or irritation. The ointment is spread lightly and covered, making this instruction incorrect and potentially harmful for proper administration.

Choice A reason: Asking parents to wait outside may increase the preschooler’s anxiety, as parental presence provides comfort. Unless clinically necessary, excluding parents is not ideal, so this action is inappropriate for preparing the child, making it incorrect.
Choice B reason: Teaching deep-breathing to a preschooler is challenging due to their developmental stage, and it may not effectively reduce anxiety for a dressing change. Simpler reassurance is more suitable, so this is less effective, making it incorrect.
Choice C reason: Explaining the procedure in simple terms helps the preschooler understand what to expect, reducing fear and promoting cooperation. This developmentally appropriate approach aligns with pediatric care principles, making it the correct action for preparation.
Choice D reason: Limiting teaching to 20 minutes is impractical for a preschooler, whose attention span is short. Brief, simple explanations are more effective, and prolonged sessions may overwhelm the child, so this is incorrect for preparing them.
