While assessing a client with Graves' disease, the nurse notes that which of the following situations may contribute to making the symptoms worse:

A. The patient has recently received a raise and a promotion at work: Positive life events, such as a raise or promotion, are less likely to cause significant worsening of symptoms. Positive changes are generally less impactful than negative stressors on thyroid conditions. B. The patient has recently lost their job and their mother has recently been diagnosed with breast cancer: Losing a job and dealing with a loved one's serious illness can lead to significant stress, which can contribute to increased thyroid hormone production and worsen hyperthyroid symptoms. C. The patient has recently changed their bedtime routine and now is getting 7-8 hours of sleep each night: Adequate rest (7-8 hours per night) is beneficial for overall health, including thyroid function. Consistent sleep routine can help improve symptoms of Graves' disease. D. The patient has recently lost 10 lbs because they have modified their dietary intake and began walking 1-2 miles each day: Exercise and weight loss from healthy lifestyle changes (diet and walking) are generally beneficial and can improve symptoms of Graves' disease.
