(Select All That Apply): A nurse is educating a client about the psychosocial factors that can influence or be influenced by depression. Which of the following factors are associated with depression and its effects on cognitive processes? Select all that apply.

The correct answer is choicea. MDD is more prevalent in older adults.

Choice A rationale:

Major depressive disorder (MDD) is indeed more prevalent in older adults.This demographic often faces unique stressors such as chronic illness, loss of loved ones, and social isolation, which can contribute to higher rates of depression.

Choice B rationale:

MDD is not primarily caused by a single factor.It is a complex disorder with multiple contributing factors, including genetics, brain chemistry, environmental influences, and psychological factors.

Choice C rationale:

Anhedonia refers to the loss of interest or pleasure in activities that were once enjoyable, not excessive sleeping.Excessive sleeping is known as hypersomnia.

Choice D rationale:

MDD cannot be diagnosed if only one symptom is present.The diagnosis requires the presence of multiple symptoms, including depressed mood or anhedonia, for at least two weeks.

Choice A rationale:

Symptoms of major depressive disorder (MDD) are characterized by causing significant distress, not mild distress. The distress associated with MDD is usually severe and impairs daily functioning.

Choice B rationale:

While insomnia is a common symptom of major depressive disorder (MDD), it is not necessary for the diagnosis. Other symptoms, such as changes in appetite, psychomotor agitation or retardation, fatigue, and diminished interest or pleasure, can also contribute to the diagnosis.

Choice C rationale:

The correct answer. Symptoms of major depressive disorder (MDD) must not be due to a medical condition. It's crucial to rule out medical conditions that can mimic depressive symptoms, such as hypothyroidism or certain neurological disorders.

Choice D rationale:

The presence of a manic or hypomanic episode would indicate a diagnosis of bipolar disorder, not major depressive disorder (MDD). Bipolar disorder involves distinct periods of both elevated mood and depressive episodes.

Choice E rationale:

The correct answer. To meet the diagnostic criteria for major depressive disorder (MDD) according to DSM-5, an individual must experience five or more symptoms of depression during a continuous two-week period. These symptoms must include either depressed mood or loss of interest/pleasure. The scenario did not specify all the symptoms, but the persistent feelings of sadness, guilt, worthlessness, weight loss, and insomnia described align with the criteria.
