A nurse is reinforcing teaching with an adolescent who has a prescription for tretinoin topical for the treatment of acne.Which of the following instructions should the nurse include in the teaching?

Choice A rationaleTretinoin should be applied to the face after it has been cleaned and dried, but a longer wait time than 5 minutes may be recommended to ensure the skin is completely dry.Choice B rationaleUsing a dime-sized amount might be too little or too much depending on the treatment area. Specific application instructions should be based on professional guidance.Choice C rationaleUsing sunscreen with an SPF of 15 or higher is essential when using tretinoin as it makes the skin more sensitive to sunlight, increasing the risk of sunburn and damage.Choice D rationaleTretinoin is generally applied at night because it can make the skin more sensitive to sunlight. Applying it in the morning could lead to increased photosensitivity and risk of skin irritation.
