A client present with a serum sodium level of 115 mEq/L. A priority nursing intervention is: A. Seizure precautions B. Vital signs every 2 hours C. Frequent oral care D. Cardiac rhythm monitoring

What is A. Seizure precautions. Rationale: Clients with hyponatremia are at high risk for seizures. Vital sign assessment is important, but client safety takes priority. Frequent oral care would be important in a client with hypernatremia or fluid volume deficit. Cardiac monitoring is important in hyperkalemia or hypokalemia.

500
A client who has experienced cardiac arrest is most at risk for: A. Metabolic acidosis B. Respiratory alkalosis C. Hyponatremia D. Fluid volume excess
What is A. Metabolic acidosis Rationale: Cardiac arrest is associated with tissue hypoxia and development of lactic acidosis. This causes a metabolic acidosis.
500
Too much of which electrolyte can lead to respiratory depression and arrest? A. Calcium B. Magnesium C. Potassium D. Chloride
What is B. Magnesium Rationale: Magnesium is important in the transmission of neuromuscular impulses. Too much magnesium may cause respiratory muscle depression leading to respiratory depression and arrest. Calcium is found mostly in teeth and bones and is involved in blood coagulation. It is also involved in muscle contraction and nerve impulse transmission. Potassium is necessary for the transmission of nerve impulses, cardiac rhythms, and muscle contraction. Chloride is found in the blood and in the stomach combined with other substances.
