A nurse is preparing to administer diphenhydramine 50 mg PO every 6 hr to a client who has acute dystonia. The available medication is diphenhydramine 25 mg tablets.

How many tablets should the nurse administer per dose?

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: Communicating empathy for the client’s feelings to increase rapport is an important aspect of nursing care. It helps in building a therapeutic relationship with the client, which can facilitate better communication and cooperation during treatment. However, while this is a valuable intervention, it does not take priority over monitoring for adverse effects of refeeding in a client diagnosed with anorexia nervosa who has begun to gain weight.

Choice B rationale: Helping the patient balance energy expenditure and caloric intake is a crucial part of the treatment plan for anorexia nervosa. This intervention aims to ensure that the client is receiving adequate nutrition for their body’s needs without excessive energy expenditure that could hinder weight gain. However, this intervention is not as immediate a priority as monitoring for refeeding syndrome, which can have severe and potentially life-threatening consequences.

Choice C rationale: Assessing for adverse effects of refeeding is the priority nursing intervention in this scenario. Refeeding syndrome is a serious and potentially life-threatening condition that can occur when nutritional replenishment is initiated in severely malnourished clients, such as those with anorexia nervosa. It is characterized by metabolic alterations, including hypophosphatemia, hypokalemia, and hypomagnesemia. These alterations can lead to serious complications, such as cardiac arrhythmias, respiratory failure, and neurological complications.

Therefore, early detection and management of refeeding syndrome are crucial.

Choice D rationale: Assessing for depression and anxiety during every shift assessment is an important part of psychiatric nursing care. Many individuals with anorexia nervosa also experience co-morbid psychiatric conditions, such as depression and anxiety disorders. Regular assessment can help detect any changes in the client’s mental status and prompt timely intervention. However, while this is an important aspect of care, it does not take priority over assessing for the adverse effects of refeeding.
