Final answer:
Critical signs of deterioration in anorexia nervosa include decreased body weight, low blood pressure, and abnormal electrolyte levels, all of which indicate a worsening of the patient's health condition.
Step-by-step explanation:
In reviewing a medical record for indications that a client with anorexia nervosa's condition is deteriorating, several critical signs should be assessed. These include:
- Decreased body weight: Continual loss of weight below a healthy range indicates a worsening condition.
- Increased heart rate: However, anorexia nervosa typically presents with a decreased heart rate due to the body's adaptation to malnutrition and reduced energy expenditure, not an increased one.
- Low blood pressure: Persistently low blood pressure can reflect cardiovascular complications due to malnutrition.
- Abnormal electrolyte levels: These indicate nutrient imbalances, which can lead to serious cardiac and neurological consequences.
Among these indicators, decreased body weight, low blood pressure, and abnormal electrolyte levels are all signs of a deteriorating condition in someone with anorexia nervosa.
