In which scenario might a nurse be concerned about a client experiencing major depressive disorder?

The scenario involving loss of appetite and weight seven months after a loved one's death is indicative of a concerning state that aligns with the criteria for major depressive disorder. Major depressive disorder often presents with symptoms such as significant weight loss, changes in appetite, lack of energy, and persistent feelings of sadness or hopelessness. The duration of the symptoms is critical; if weight loss and loss of appetite continues for a considerable period, such as seven months, it can suggest a shift from normal grief to a more serious depressive condition.

Normal grieving processes typically show an improvement in functioning and mood over time, especially as individuals begin to adapt to their loss. However, persistent issues such as drastic changes in appetite and weight over an extended period are red flags that warrant further evaluation. This can indicate that the individual may be struggling with more than situational sadness and could benefit from further assessment and potential intervention for major depressive disorder.

The other scenarios may reflect normal grieving processes or transient feelings of sadness, which, while significant and deserving of support, do not necessarily align with the clinical diagnosis of major depressive disorder.
