A client with scabies is prescribed lindane. What instructions should the nurse provide?

The correct answer involves instructing the client to leave the cream on for a designated period of 8 to 12 hours and then remove it by washing. This is critical for ensuring the medication effectively kills the scabies mites. Lindane is a potent topical agent utilized in the treatment of scabies, and allowing it to remain on the skin for the specified duration maximizes its effectiveness. After this time, washing it off helps to minimize potential skin irritation and prevents unnecessary exposure to the medication, which could lead to absorption-related toxicity if left on for too long.

The instructions about application can also specify how to apply the medication, but it is essential that the patient understands the importance of adhering to the recommended duration of treatment to achieve the desired results.
