A nurse is teaching the partner of a client who had a stroke about dysphagia. Which of the following statements by the client's partner should indicate to the nurse that the teaching was effective?
A) "I understand that dysphagia means difficulty swallowing, and it's common after a stroke because the muscles used for swallowing can be weakened."
B) "I learned that it's important to position my partner upright while eating and drinking to help prevent choking or aspiration."
C) "The nurse explained that we should thicken liquids to make them easier to swallow and avoid thin liquids like water."
D) "I now know the signs of aspiration pneumonia to watch out for, like coughing or choking during meals, and I'll notify the healthcare provider if we notice any of these signs."
