A client diagnosed with myasthenia gravis receives a prescription for pyridostigmine. Which intervention should the nurse implement when preparing to administer this medication?

A. Schedule the medication to be given just before bedtime: Pyridostigmine should be timed to coincide with periods of increased activity, especially before meals, to improve muscle strength. Giving it at bedtime would not offer functional benefit unless the client experiences nighttime symptoms.

B. Break the medication into small pieces and sprinkle onto food: Pyridostigmine tablets are not designed to be crushed or split unless specifically directed. Altering the form may affect its absorption and reduce its effectiveness in managing symptoms of myasthenia gravis.

C. Instruct the client to avoid dairy products for at least 30 minutes: Dairy does not interfere significantly with the absorption or action of pyridostigmine. Dietary restrictions should be based on known drug-food interactions, which are not typically associated with pyridostigmine and dairy.

D. Administer the medication thirty minutes prior to meals: Administering pyridostigmine before meals helps enhance swallowing and chewing abilities, reducing the risk of aspiration. This timing optimizes muscle strength during eating, which is a high-risk activity for clients with myasthenia gravis.

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.
