Final answer:
Henri can expect his dying friend to potentially experience various stages of grief as proposed by Elizabeth Kübler-Ross, which include denial, anger, bargaining, depression, and acceptance.
Step-by-step explanation:
Based on Elizabeth Kübler-Ross's model, Henri can expect his dying friend to go through stages in coming to terms with death. Although not all individuals will experience each stage in order and some might not go through every stage, it is likely his friend could display behaviors associated with these stages, including denial, anger, bargaining, depression, and acceptance.
Initially, the friend may be in denial, not fully accepting the reality of the situation. This could evolve into anger about their fate, possibly followed by bargaining in hopes of delaying the end. A period of depression might ensue as the reality sinks in. Lastly, they may reach a state of acceptance, where they can discuss their feelings more openly and come to terms with their impending death, facing it as a natural part of life.
