A nurse is providing teaching to a client who has oral candidiasis and a new prescription for nystatin suspension. Which of the following statements by the client indicates an understanding of the teaching?

A. "I will take the medicine every morning on an empty stomach.": Nystatin suspension is not dependent on an empty stomach for effectiveness. The key is to ensure contact with oral mucosa by swishing before swallowing, not timing it with meals. B. "I will only need to take this medication for a few days.": Treatment with nystatin usually lasts at least 7 to 14 days, and it must be continued for the full prescribed course even if symptoms improve early to prevent recurrence. C. "I will spit the medication out after swishing it around my mouth.": The medication should be swished thoroughly in the mouth and then swallowed, allowing it to treat both oral and pharyngeal yeast infections. Spitting it out reduces its therapeutic effect. D. "I will store the medication at room temperature.": Nystatin oral suspension should be stored at room temperature away from direct light and freezing. This preserves its stability and effectiveness, making this the correct statement.
