According to the commonly cited Kübler-Ross model, which of the following is one of the stages of grief?

The Kübler-Ross model commonly describes five stages of grief: denial, anger, bargaining, depression, and acceptance. Bargaining — attempting to negotiate or make deals to postpone or undo a loss — is one of these stages. The model is widely taught as a general framework, with the understanding that grief is individual and people do not necessarily move through the stages in order or experience all of them. Sublimation and projection are defense mechanisms, not grief stages, and 'memorization' is unrelated. Recognizing the commonly cited grief stages is a standard psychosocial concept. (This reflects a widely taught model; verify against current NCLEX prep materials.)
