A mental health nurse is providing teaching for a client who has major depressive disorder (MDD) and is seeking voluntary admission to an acute mental health facility.
Which of the following statements should the nurse include?

Choice A rationale: Bradycardia

Bradycardia, or an abnormally slow heart rate, is a common cardiovascular manifestation in individuals with anorexia nervosa. It is often a result of the body’s adaptive response to conserve energy due to severe malnutrition and reduced caloric intake. This is because the body is trying to conserve as much energy as possible, and one way it does this is by slowing down the heart rate. This can be dangerous, however, as it can lead to fainting, heart failure, or even death if not properly managed.

Choice B rationale: Hyperactive bowel sounds

Hyperactive bowel sounds are not typically associated with anorexia nervosa. Instead, individuals with this disorder often experience constipation and other gastrointestinal issues due to inadequate food intake. The lack of food intake can slow down the digestive process, leading to these symptoms.

Choice C rationale: Dental erosion

Dental erosion can be a consequence of anorexia nervosa, but it is more commonly associated with bulimia nervosa due to the frequent vomiting that characterizes this disorder. The stomach acid that comes into contact with the teeth during vomiting can cause the enamel to erode. However, it’s important to note that not all individuals with anorexia nervosa will experience this symptom.

Choice D rationale: Hypertension

Hypertension, or high blood pressure, is not typically associated with anorexia nervosa. In fact, low blood pressure (hypotension) is more common due to the decreased volume of blood in the body from insufficient nutrition.

Hypertension is more commonly associated with conditions such as obesity and metabolic syndrome.

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.
