A patient has not had a menstrual period for 8 months. She is 5 feet 5 inches tall and weighs 115 pounds. She does not binge, but she misuses laxatives on a daily basis. What is the priority nursing diagnosis for the patient?

Choice A rationale Ineffective denial is a psychological defense mechanism where the patient refuses to acknowledge the reality of their condition or the severity of their weight loss. While this is common in eating disorders, it is not the physiological priority. In the hierarchy of needs, physiological stability must be addressed before psychological barriers. The patient is already experiencing amenorrhea for eight months, indicating that the body is in a state of starvation and hormonal shutdown due to insufficient fat stores. Choice B rationale Imbalanced nutrition is the priority because the patient weighs 115 pounds at 5 feet 5 inches, which is on the lower end of normal, but her symptoms of amenorrhea and daily laxative misuse indicate a severe nutritional deficit. Laxative misuse leads to electrolyte imbalances, such as hypokalemia (normal potassium 3.5 to 5.0 mEq/L) and metabolic acidosis. These physical complications can lead to cardiac dysrhythmias and organ failure, making physiological stabilization the most urgent nursing action. Choice C rationale Body image disturbance is a core component of eating disorders where the individual perceives their body size inaccurately. While addressing this is vital for long term recovery, it does not pose an immediate threat to life. The nurse must first ensure the patient survives the physical effects of chronic laxative use and malnutrition. Amenorrhea signifies that the hypothalamic-pituitary-gonadal axis is suppressed due to low body weight, which requires urgent nutritional intervention to restore biological functioning. Choice D rationale Anxiety is frequently comorbid with eating disorders and laxative misuse, often stemming from a fear of weight gain or loss of control. While anxiety affects the patient's quality of life and adherence to treatment, it is ranked lower than physiological needs. The nurse must prioritize the assessment of dehydration and malabsorption caused by the daily laxatives. Stabilizing the metabolic rate and restoring energy balance through adequate nutrition takes precedence over managing the patient's emotional distress.
