Final answer:
Raquelle and her family are likely in the denial phase of grief, where they are going through the motions of daily life while in shock over the sudden loss. This stage is the first in Elisabeth Küber-Ross's model, which includes denial, anger, bargaining, depression, and acceptance.
Step-by-step explanation:
Raquelle and her family are most likely in the denial phase of grief after the sudden death of her mother. This first stage is characterized by shock and disbelief, where the person may not want to believe that the loss is real. According to Elisabeth Küber-Ross's model, the five stages of grief are denial, anger, bargaining, depression, and acceptance, often experienced in that order, although they can occur in different sequences and some individuals may not go through all the stages.
In the denial phase, individuals often go through the motions of daily life, seemingly numb to the reality of the loss. This stage serves as a temporary defense mechanism to buffer the immediate shock, allowing individuals to process the reality of the situation at their own pace. Over time, as the denial fades, they may move onto the next stages of grief.
