JG has been taking metoclopramide 10 mg po q6h for the past 3 days as part of her chemotherapy regimen. She normally takes 4 doses daily, 30 minutes prior to meals and at bedtime. This morning, she forgot to take her morning dose before leaving home for a hospital check-up. When she arrives at the clinic, she asks the pharmacist what she should do about her missed dose, as she expects to be home again around 11:00 am. The pharmacist should advise JG to:

Option A is not the best option because taking a double dose at once can increase the risk of side effects. It is also not necessary to take the missed dose immediately as the effects of metoclopramide can last for several hours. Option B is also not recommended as taking two doses at once can lead to unwanted side effects. Option D is not the best option as it can disrupt JG's usual schedule and may cause confusion about when to take the next dose. Therefore, the best option is to skip the missed dose and resume the regular dosing schedule at lunchtime. This can help prevent the risk of side effects and maintain a consistent dosing schedule.
