In maintaining homeostasis, organisms must regulate various physiological processes, including the transport of ions across cell membranes. One of the critical transport mechanisms employed by cells involves the sodium-potassium pump. This active transport mechanism is vital for maintaining the electrochemical gradients across the plasma membrane of animal cells.

The sodium-potassium pump functions by moving sodium ions (Na⁺) out of the cell while bringing potassium ions (K⁺) in, against their concentration gradients. This process is crucial for various physiological functions, including muscle contraction and nerve impulse transmission. The pump utilizes ATP as an energy source to facilitate this transport.

Consider the effects of a malfunctioning sodium-potassium pump. Such a malfunction would potentially disrupt cellular balance and lead to significant physiological impairments. Based on the information provided, what would be a likely consequence of impaired function of the sodium-potassium pump?
