An adolescent receives a new prescription for isotretinoin for cystic acne. Which information is most important for the nurse to provide?

A. Start the second course of therapy after an 8-week delay: While a second course of isotretinoin may sometimes be considered after a break if acne persists, this timing is medication management guidance and is less urgent than immediate safety concerns like sun sensitivity.B. Consider an alternative summer job, other than life guarding: Isotretinoin causes extreme photosensitivity, making prolonged sun exposure dangerous. Adolescents working outdoors, like lifeguards, are at high risk for severe sunburns, so suggesting alternative employment protects their health.C. Store the medicine in a plastic, tight, light resistant container: Proper medication storage is important but not the most critical concern compared to preventing serious adverse effects like sunburn, teratogenicity, or psychiatric symptoms with isotretinoin use.D. Discontinue all multivitamins during acne medication therapy: There is generally no need to discontinue all multivitamins while taking isotretinoin unless specifically instructed by the healthcare provider. Some multivitamins contain vitamin A, excessive intake of vitamin A should be avoided. However, discontinuing all multivitamins without guidance could lead to other nutritional deficiencies.
