Final answer:
Clients with advanced Alzheimer's disease and gastroesophageal reflux disease are at increased risk of aspiration pneumonia.
Step-by-step explanation:
The nurse would identify client A, the client with a history of advanced Alzheimer's disease, and client D, the client with a history of gastroesophageal reflux disease, as being at increased risk for aspiration pneumonia.
Advanced Alzheimer's disease impairs a person's ability to swallow and increases the risk of food or liquids entering the lungs, leading to aspiration pneumonia.
Gastroesophageal reflux disease (GERD) can cause stomach acid to flow back up into the throat, increasing the risk of aspiration pneumonia.
