Final answer:
The nurse should allow the client cool liquids only after an esophagogastroduodenoscopy (EGD) to soothe discomfort and keep the client hydrated.
Step-by-step explanation:
The best action for the nurse to take in this situation is to allow the client cool liquids only. After an esophagogastroduodenoscopy (EGD), the client's throat may be sore, and cool liquids can help soothe the discomfort. Assessing the client's gag reflex is important before providing any oral intake, but in this case, since the client is specifically requesting something to drink, allowing cool liquids is appropriate. Reminding the client to remain NPO (nothing by mouth) or telling the client to wait 4 hours may not meet the client's immediate need for hydration and relief.
