A client is in a motor vehicle accident with severe thoracic trauma. Which acid-base imbalance is most likely to develop?

A. "If I stop sweating, I should call 911 or get to the Emergency Department quickly.” An absence of sweating can indicate heat stroke, a medical emergency.

B. "If this happens in the future, lying in cool water would be beneficial.” Cooling measures like cold baths, ice packs, and shade help reduce body temperature.

C. “Using salt tablets to replenish my electrolytes may lead to nausea and vomiting.” Salt tablets can irritate the stomach and cause nausea, vomiting, and hypernatremia.

D. "Drinking water is the best way to improve sodium intake.” While water helps with rehydration, it does not replace lost sodium. Excessive water intake without electrolytes can cause hyponatremia, leading to confusion, seizures, or coma. Electrolyte-containing drinks (e.g., sports drinks, oral rehydration solutions) are better choices.

A. Administer supplemental oxygen: Hypokalemia primarily affects cardiac and neuromuscular function, not oxygenation. Oxygen may be needed if dysrhythmias develop but is not the highest priority.

B. Seizure precautions: While severe hypokalemia can cause muscle weakness, seizures are not the primary concern. Cardiac effects take priority.

C. Cardiac monitoring: A potassium level of 2.2 mEq/L is critically low, increasing the risk of life-threatening cardiac arrhythmias. Continuous cardiac monitoring helps detect dangerous dysrhythmias like ventricular tachycardia.

D. Initiating a fluid restriction: Fluid restriction is more relevant for hyperkalemia or fluid overload, not hypokalemia.
