A mental health nurse is caring for a client who smokes and has lung cancer.
The client reports, "I'm coughing because I have that cold everyone has been getting." The nurse should identify that the client is using which of the following defense mechanisms?

Choice A rationale: Anorexia nervosa is an eating disorder characterized by relentless drive for thinness with a fear of gaining body weight associated with self-induced behaviors towards thinness. Symptoms include extreme weight loss, thin appearance, intense fear of gaining weight, bingeing and purging, abnormal blood counts, fatigue, insomnia, dizziness or fainting, bluish discoloration of the fingers, hair that thins, breaks or falls out, soft, downy hair covering the body, amenorrhea (absence of menstruation), constipation, dry or yellowish skin, intolerance of cold, irregular heart rhythms, low blood pressure, dehydration, osteoporosis, swelling of arms or legs. However, the client’s symptoms do not align with those of anorexia nervosa.

Choice B rationale: Bulimia nervosa is an eating disorder characterized by binge eating, followed by methods to avoid weight gain. Symptoms include binge eating, forceful vomiting, long-term fear of gaining weight, preoccupation with weight and body, a strong negative self-image, overuse of laxatives or diuretics, use of supplements or herbs for weight loss, excessive exercises, stained teeth (from stomach acid), calluses on the back of the hands, withdrawal from normal social activities. The client’s symptoms of using laxatives frequently and running for 1 hr after eating a very large meal, which happens at least 9 times a week, align with those of bulimia nervosa.

Choice C rationale: Histrionic personality disorder (HPD) is a mental health condition characterized by unstable emotions, a distorted self-image and a desire to be noticed. Symptoms include persistent attention seeking, dramatic behavior, rapidly shifting and shallow emotions, sexually provocative behavior, undetailed style of speech, and a tendency to consider relationships more intimate than they actually are. The client’s symptoms of feelings of anxiety and depression, starting smoking marijuana as that is what their “new friends do all the time”, and being recently arrested for stealing make-up from a local department store and acknowledging that this “is the first time I was caught” align with those of HPD.

Choice A rationale:

Protecting the client from injury is the highest priority nursing action in this scenario. Here's a detailed rationale explaining the importance of this action:

1. Imminent Risk of Harm:

Acute anxiety can significantly impair judgment and impulse control, escalating the risk of self-harm or harm to others. It's crucial to prevent any actions that could result in physical injury, even if unintended.

2. Physiological Manifestations:

Anxiety can trigger physiological responses that heighten the potential for harm, such as: Increased heart rate and blood pressure

Hyperventilation Diaphoresis

Agitation and restlessness Dissociation

These physiological changes can contribute to accidents, falls, or other injuries.

3. Impaired Decision-Making:

Acute anxiety often clouds rational thinking and decision-making abilities.

Individuals may engage in behaviors they wouldn't consider in a calmer state, such as running away, lashing out, or attempting self-harm.

The nurse's role is to safeguard the client from potential consequences of these impulsive actions.

4. Establishing Safety as a Foundation for Care:

Ensuring physical safety creates a necessary foundation for subsequent interventions.

Once safety is established, the nurse can proceed with assessing coping skills, identifying anxiety triggers, and implementing therapeutic strategies.

5. Protecting Others:

In rare cases, acute anxiety can manifest in aggression towards others.

The nurse must protect not only the client but also other individuals who may be at risk.

6. Ethical and Legal Obligations:

Nurses have a professional duty to protect clients from harm, upholding ethical principles and legal standards of care.

7. Preventing Trauma:

Physical injuries sustained during a crisis can exacerbate anxiety and complicate recovery. Proactive safety measures aim to prevent further trauma and promote healing.

I'll provide detailed rationales for the other choices in separate messages to ensure clarity and comprehensiveness.
