A 78 year old male has been working on his lawn for two days, although the temperature has been above 90 degree F. he has been on thiazide diuretics for hypertension. His lab values are K 3.7 mEq/L, Na 129 mEq/L, Ca 9 mg/dl, and Cl 95 mEq/L. What would be a priority action for this man?

  • A. Make sure he drinks 8 glasses of water a day.
  • B. Monitor for fatigue, muscle weakness, restlessness, and flushed skin
  • C. Look for signs of hyperchloremia
  • D. Observe for neurologic changes
Correct Answer: B

Rationale: The 78-year-old male in this scenario is at risk for electrolyte imbalances due to prolonged exposure to high temperatures while taking thiazide diuretics, commonly prescribed for hypertension. The low potassium level (K 3.7 mEq/L) and low sodium level (Na 129 mEq/L) in his lab results are indicative of potential electrolyte disturbances, especially considering his age and medication. These electrolyte imbalances can lead to symptoms like fatigue, muscle weakness, restlessness, and flushed skin, which are signs of hyponatremia and hypokalemia.
