Final answer:
The nurse should assess for Obstructive sleep apnea in a 64-year-old obese man with heart failure, as it is a common consequence of obesity and may be exacerbated by alcoholism.
Step-by-step explanation:
The nurse should assess for Obstructive sleep apnea (B) as a potential negative consequence for a 64-year-old obese man admitted to the hospital for treatment of heart failure secondary to alcoholism. Obesity is a risk factor for several negative health consequences, including cardiovascular disease, Type 2 diabetes, liver disease, and obstructive sleep apnea. The added effect of alcohol may exacerbate muscle relaxation during sleep, increasing the risk and severity of obstructive sleep apnea, which is more common in older, overweight individuals and can significantly impact the patient's quality of life and exacerbate heart failure symptoms.
