A patient’s chart indicates a history of hyperkalemia. Which of the following would you not expect to see with this patient if this condition were acute?
A. Decreased HR
B. Paresthesias
C. Muscle weakness of the extremities
D. Migraines
Correct Answer: D. Migraines
Migraines are not a symptom of hyperkalemia. Symptoms of hyperkalemia, when present, are nonspecific and predominantly related to muscular or cardiac function.
Option A: Occasionally, a cardiac examination may reveal extrasystoles, pauses, or bradycardia resulting from heart block or tachypnea resulting from respiratory muscle weakness.
Option B: Paresthesias refers to a burning or prickling sensation that is usually felt in the hands, arms, legs, or feet, and is common in hyperkalemia.
Option C: Skeletal muscle weakness and flaccid paralysis may be present, along with depressed or absent deep tendon reflexes.
