Correct answer: A — Check product and thickener compatibility because macrogol may affect fluid thickness

Some medicines and formulations can alter the consistency of thickened fluids, affecting swallowing safety. Macrogol must be prepared correctly, but dysphagia plans also need to be respected. The pharmacist should check compatibility guidance and liaise with speech and language therapy or the prescriber if needed. Giving powder dry would be unsafe.
