The correct answer to today’s NCLEX-RN® Question is…
A. Initiate cardiac monitoring
Rationale: Because hypokalemia affects the transmission of cardiac conduction, the client is at risk for developing cardiac arrhythmias. Cardiac monitoring should be initiated immediately. In addition, vital signs, including respiratory status should be monitored.
Major takeaway
Because hypokalemia affects the transmission of cardiac impulses, the client is at risk for developing cardiac arrhythmias. Cardiac monitoring has the highest priority.
Incorrect answer explanations
B. Initiate seizure precautions
Rationale: Seizure precautions are not indicated for a client experiencing hypokalemia.
C. Institute hourly neurologic checks
Rationale: Although hypokalemia can lead to lethargy and altered level of consciousness, neurological checks are not the priority.
D. Administer oxygen via face mask
Rationale: Although hypokalemia may alter respiratory function, administering oxygen is not the priority.
