A client with a phobia is experiencing physiological symptoms such as palpitations, sweating, and shortness of breath. These symptoms are most likely due to:

Choice A rationale:

The client's fear of flying in airplanes and the intense panic response when even thinking about it are indicative of a specific phobia. Specific phobias involve an intense and irrational fear of a specific object, situation, or activity. In this case, the fear of flying is specific and triggers a significant anxiety reaction.

Choice B rationale:

Social phobia (also known as social anxiety disorder) involves an excessive fear of social situations where the individual fears being scrutinized or judged by others. This fear extends beyond a specific object or situation, which is not the case in this scenario.

Choice C rationale:

Agoraphobia involves a fear of situations where escape might be difficult or help might not be available if a panic attack occurs. This fear often leads to avoidance of various places or situations, such as crowded spaces. The client's fear of flying is not characteristic of agoraphobia.

Choice D rationale:

Panic disorder is characterized by recurrent and unexpected panic attacks, often accompanied by a fear of having additional attacks. While the client does experience panic symptoms related to the fear of flying, the primary issue is the specific fear of flying itself, suggesting a specific phobia rather than panic disorder.

Choice A rationale:

The client reporting decreased fear and anxiety related to phobias (Choice A) is a subjective outcome that might not accurately reflect the effectiveness of the nursing interventions. It relies solely on the client's self-report and might not provide an objective measure of improvement.

Choice B rationale:

The client demonstrating increased avoidance behavior (Choice B) is not an outcome aimed at reducing fear and anxiety. Increased avoidance behavior would actually indicate a worsening of the phobia-related symptoms, as the client is avoiding the feared stimulus more.

Choice C rationale:

The client engaging in exposure therapy without excessive distress (Choice C) is a desired outcome for interventions targeting phobias. Exposure therapy involves gradually exposing the client to the feared stimulus in a controlled manner. If the client can tolerate exposure without excessive distress, it indicates a positive response to the intervention and a reduction in fear and anxiety over time.

Choice D rationale:

The client applying cognitive-behavioral techniques ineffectively (Choice D) is not a desirable outcome. The goal of cognitive-behavioral techniques is to equip the client with effective coping strategies to manage their phobias. If the client is applying these techniques ineffectively, it indicates a need for further intervention or adjustment of the therapeutic approach.
