The community health nurse recognizes that which of the following mental health issues is most prevalent in the homeless population?

Choice A rationale:

Tremors. Rationale: Tremors can be a withdrawal symptom associated with alcohol withdrawal. These tremors are often referred to as "alcohol shakes" and are a result of the central nervous system adapting to the sudden absence of alcohol.

Choice B rationale:

Insomnia. Rationale: Insomnia is a common withdrawal symptom during alcohol withdrawal. Alcohol disrupts sleep patterns, and when a person stops drinking, their sleep cycle may be disturbed, leading to difficulty falling asleep or staying asleep.

Choice C rationale:

Severe hypotension. Rationale: Severe hypotension, or very low blood pressure, is not a prominent withdrawal symptom of alcohol. Alcohol withdrawal can lead to an increase in blood pressure rather than severe hypotension.

Choice D rationale:

Hyperglycemia. Rationale: Hyperglycemia, or high blood sugar, is not a direct withdrawal symptom of alcohol. However, chronic alcohol use can affect blood sugar regulation over time. During acute withdrawal, hypoglycemia (low blood sugar) is more common due to altered metabolism.

Choice E rationale:

Visual hallucinations. Rationale: This statement is correct. Visual hallucinations can occur during alcohol withdrawal and are often indicative of a more severe withdrawal syndrome known as delirium tremens (DTs). DTs can include visual hallucinations, confusion, agitation, and autonomic hyperactivity.

The correct answer is choice D: Continuous worry about the undiagnosed presence of an illness.

Choice A rationale:

Sudden unexplained loss of peripheral sensation is not typically associated with illness anxiety disorder. This symptom may be indicative of a neurological condition and would require further medical evaluation to determine the cause.

Choice B rationale:

Obsession over a fictitious defect in physical appearance is more characteristic of body dysmorphic disorder, not illness anxiety disorder. Individuals with body dysmorphic disorder are preoccupied with one or more perceived defects or flaws in their physical appearance, which are not observable or appear slight to others.

Choice C rationale:

Having prior physical health followed by the need for two surgeries within the last three months does not necessarily indicate illness anxiety disorder. This choice does not provide enough context to link it to illness anxiety disorder, as it could be related to many other health conditions.

Choice D rationale:

Continuous worry about the undiagnosed presence of an illness is a key finding in illness anxiety disorder. Individuals with this disorder are excessively concerned with and preoccupied by the belief that they have, or are in danger of developing, a serious undiagnosed illness despite medical reassurance.
