Choice A rationaleMuscle rigidity is not commonly associated with hypokalemia. Hypokalemia causes muscle weakness, cramps, and possible paralysis, but not rigidity. Potassium is critical for muscle function, and low levels cause flaccid, not rigid muscles.Choice B rationaleHypokalemia does not cause bounding radial pulses. Instead, it can lead to weak and irregular pulses due to its effect on cardiac muscle excitability. Potassium is crucial for normal cardiac rhythm and contractility.Choice C rationaleHypokalemia causes depressed deep tendon reflexes due to reduced excitability of neurons. Normal potassium levels (3.5 to 5 mEq/L) are essential for proper neuromuscular function; low levels impair nerve impulse transmission.Choice D rationaleIncreased bowel motility is not a typical finding in hypokalemia. Hypokalemia can cause decreased bowel motility and constipation due to reduced smooth muscle contraction. Potassium is vital for smooth muscle activity.
