Final answer:
The best response is for the nurse to acknowledge that the wife's behavior is a coping mechanism for the intense pain and process of labor.
Step-by-step explanation:
The best response by the nurse in this situation would be C. She must concentrate to cope with her labor.
During labor, a woman's body is undergoing intense physical and emotional changes. These changes can cause a woman to become distant, lose interest in conversation, and be short with others. This is a normal response to the pain and intensity of labor and is often a coping mechanism for the woman.
By acknowledging that the wife's behavior is a result of her needing to concentrate and cope with the labor, the nurse can help the husband understand that his wife's behavior is not personal and is a normal part of the labor process.
