Potassium catalyzes the metabolism of ATP, producing the gradient that results in electrical stimulation.
Potassium is central to establishing and maintaining the resting membrane potential of cardiac muscle cells.
The impermeability of cardiac cell membranes to potassium allows for action potentials achieved by the flow of sodium ions.
The reciprocal movement of one potassium ion for one sodium ion across the cell membrane results in the production of an action potential.

“Tension and vessel thickness increase proportionately.” Question 24.24. An 81-year-old female patient of a long-term care facility has a history of congestive heart failure. The nurse practitioner caring for the patient has positioned her sitting up at an angle in bed and is observing her jugular venous distention. Why is jugular venous distention a useful indicator for the assessment of the patient's condition? (Points : 3)
Increased cardiac demand causes engorgement of systemic blood vessels, of which the jugular vein is one of the largest.
Blood backs up into the jugular vein because there are no valves at the point of entry into the heart.
Peripheral dilation is associated with decreased stroke volume and ejection fraction.
Heart valves are not capable of preventing backflow in cases of atrial congestion.

“Nephrons are delicate structures that cannot endure the high pressure that exists in capillary beds elsewhere in the body.”
“Glomerular filtrate is very similar in composition to blood plasma found elsewhere in circulation.”
