Multiple Choice

The nurse recognizes the client has reached Stage III of general anesthesia when the client:

Has complete muscle relaxation and absent corneal reflexes

Shows excitement and irregular breathing

Exhibits regular respiration and loss of eyelid reflexes

Is fully conscious and able to respond to commands

Verified step by step guidance

Understand the stages of general anesthesia: General anesthesia is divided into four stages (Stage I: Analgesia, Stage II: Excitement, Stage III: Surgical anesthesia, Stage IV: Medullary depression). Each stage is characterized by specific physiological responses.

Focus on Stage III: Surgical anesthesia. This stage is crucial for performing surgical procedures as it ensures the patient is unconscious, has regular respiration, and exhibits loss of reflexes such as the eyelid reflex.

Analyze the options provided: Evaluate each option based on the characteristics of Stage III. For example, complete muscle relaxation and absent corneal reflexes are associated with deeper levels of anesthesia within Stage III, but regular respiration and loss of eyelid reflexes are hallmark signs of entering Stage III.

Eliminate incorrect options: Discard options that describe characteristics of other stages. For instance, excitement and irregular breathing are signs of Stage II, while being fully conscious and responsive to commands is indicative of Stage I.

Select the correct answer: Based on the physiological markers of Stage III, the correct answer is 'Exhibits regular respiration and loss of eyelid reflexes,' as these are defining features of this stage.
