Final answer:
The nurse will assess the patient's pain level more thoroughly, considering nonverbal cues and conducting a comprehensive physical examination to identify any signs of pain or discomfort.
Step-by-step explanation:
When completing the patient assessment, the nurse will take into consideration that despite the patient denying any pain, their restlessness and tightly clenched hands indicate discomfort and potential underlying pain. Additionally, the patient moaning before the nurse entered the room further suggests pain or discomfort. Therefore, the nurse will assess the patient's pain level more thoroughly, considering nonverbal cues and conducting a comprehensive physical examination to identify any signs of pain or discomfort.
