[Solved]: Margaret Stevens, an 85-year-old woman, lives alone…

Margaret Stevens, an 85-year-old woman, lives alone and was found confused and lethargic by her neighbor. She was brought to the emergency department, where she was noted to have dry mucous membranes, tachycardia, and hypotension (BP: 88/56 mmHg, HR: 112 bpm). Her recent history reveals that she had been experiencing a decreased appetite and was drinking fewer fluids due to difficulty swallowing. She was recently started on hydrochlorothiazide for hypertension. Her serum sodium level is 124 mEq/L, and her urine sodium is low. She exhibits signs of altered mental status, including confusion and restlessness. The provider diagnoses her with dehydration-induced hyponatremia and initiates a slow correction with IV fluids. The healthcare team is also evaluating her for potential underlying causes, including medication effects and nutritional deficiencies. Discussion Questions: 1. Analyze the potential causes of Margaret’s hyponatremia and fluid volume deficit. What age- related physiological changes contribute to her condition? 2. Evaluate the risks of rapidly correcting sodium levels in this patient. What strategies should be used to safely restore her sodium balance?
