Final answer:
Chronic fatigue and poorly controlled back pain in a 51-year-old female patient can be indicative of depression as a consequent health problem.
Step-by-step explanation:
The medical history of chronic fatigue and poorly controlled back pain in a 51-year-old female patient should alert the nurse to the possibility of depression as a consequent health problem.
Depression is a common comorbidity in patients with chronic fatigue and chronic pain conditions. It can significantly impact a patient's quality of life, impair their ability to function, and exacerbate their physical symptoms.
The nurse should assess the patient for signs of depression, such as changes in sleep or appetite, loss of interest or pleasure, feelings of sadness or hopelessness, and difficulty concentrating or making decisions. Referral to a mental health professional may be necessary for further evaluation and treatment.
