David’s grandfather, who is 76, has been suffering from congestive heart failure (CHF) for the last few years. This morning his legs are swollen, his pulse is racing, and he has difficulty breathing with even the lightest activities, such as moving from bed to a sofa. It’s definitely time for serious fluid restriction! Can you help David calculate grandpa’s fluid allowance for today? David’s grandfather is 5’7" and weighs 172 lb. He already knows that, when it comes to his CHF crises, he has to lay off his favorite soups for a while and really follow the "prescribed" amounts of fluids. How many fluid ounces of liquids is he allowed to consume?
