Rationale 1: Prolongation of the PR interval is not an ECG finding associated with hypokalemia.
Rationale 2: Cardiovascular manifestations of hyperkalemia include prolonged P-R interval; flat or absent P wave; slurring of QRS; tall peaked T wave; and ST segment depression.
Rationale 3: Hypocalcemia causes prolongation of the QT interval and a long ST segment.
Rationale 4: Cardiovascular manifestations of hypernatremia include hypertension and tachycardia.
