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 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? round your answer to the nearest whole number. during calculations, use values rounded to the first decimal place.

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
