A mental health nurse is caring for a newly admitted client with obsessive-compulsive disorder (OCD). Which of the following actions should the nurse take first?

Choice A rationale:

Altered body image is a hallmark feature of eating disorders. Individuals with eating disorders often have a distorted perception of their bodies, believing they are overweight or larger than they actually are. This distorted body image can lead to intense dissatisfaction with their appearance, even when they are underweight. They may engage in obsessive behaviors such as repeatedly checking their weight, measuring their body parts, and avoiding mirrors. They may also fixate on perceived flaws in their appearance, leading to significant distress and impairment in their daily lives.

Choice B rationale:

Amenorrhea, the absence of menstruation, is a common physiological consequence of eating disorders. It occurs due to hormonal imbalances caused by insufficient intake of calories and nutrients, particularly fat. The body requires a certain amount of body fat to maintain normal reproductive function. When body fat levels fall below a critical threshold, the hypothalamus, a part of the brain that regulates hormone production, signals the pituitary gland to reduce the production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones play crucial roles in ovulation and menstruation. Without adequate levels of FSH and LH, ovulation and menstruation do not occur.

Choice C rationale:

Hyperactivity, characterized by excessive energy and restlessness, can manifest in individuals with eating disorders. This increased activity level may be a way to burn calories or compensate for perceived overeating. It may also be a way to distract themselves from thoughts about food and body image. The hyperactivity can present in various forms, such as excessive exercise, fidgeting, or constant movement.

Choice D rationale:

Bradycardia, a slower-than-normal heart rate, is another physiological sign that can accompany eating disorders. It occurs as the body attempts to conserve energy in response to inadequate caloric intake. The heart rate slows down to minimize energy expenditure. Bradycardia can have serious health implications, including fatigue, dizziness, fainting spells, and potentially life- threatening heart arrhythmias.

Choice E rationale:

Verbalized desire to gain weight is not a typical manifestation of eating disorders. Individuals with eating disorders often have a strong fear of weight gain and a persistent drive for thinness. They may actively resist efforts to increase their weight, even when they are dangerously underweight.

Choice A rationale: The client’s magnesium level is 1.7 mg/dL, which is below the normal range of 1.8 to 2.4 mg/dL. Hypomagnesemia can cause neuromuscular irritability, muscle weakness, tremors, and even seizures or cardiac arrhythmias in severe cases.

It’s often associated with other electrolyte imbalances such as hypokalemia and hypocalcemia.

In the context of anorexia nervosa, this could be due to inadequate dietary intake, malabsorption, or excessive losses from the gastrointestinal tract.

Choice B rationale: The client’s chloride level is 98 mmol/L, which falls within the normal range of 96 to 106 mmol/L. Chloride is an important electrolyte that helps maintain acid-base balance, fluid balance, and is a component of gastric juice as hydrochloric acid.

There’s no immediate concern regarding the client’s chloride level.

Choice C rationale: The client’s phosphate level is 2.5 mg/dL, which is below the normal range of 2.8 to 4.5 mg/dL. Hypophosphatemia can lead to muscle weakness, bone pain, mental changes, and potentially life-threatening complications such as respiratory failure and heart failure.

In the context of anorexia nervosa, hypophosphatemia is a common complication during refeeding due to shifts in electrolytes.

Choice D rationale: The client’s potassium level is 3.5 mmol/L, which is at the lower end of the normal range of 3.5 to

5.0 mmol/L. Hypokalemia can cause muscle weakness, cramps, arrhythmias, and in severe cases, it can be life- threatening.

In the context of anorexia nervosa, this could be due to inadequate dietary intake, excessive losses due to vomiting or laxative abuse, or shifts in electrolytes during refeeding.

In conclusion, the nurse should follow up on the client’s magnesium, phosphate, and potassium levels due to their potential implications on the client’s health, especially considering the client’s current health status and the process of refeeding.
