A pаtient is аdmitted tо the emergency depаrtment with severe fatigue and cоnfusiоn. Which laboratory value requires the most immediate action by the nurse? Sodium (Na⁺): 135–145 mEq/L (mmol/L same) Potassium (K⁺): 3.5–5.0 mEq/L (mmol/L same) Chloride (Cl⁻): 98–106 mEq/L (mmol/L same) Bicarbonate / CO₂ (HCO₃⁻): 22–28 mEq/L Calcium (Total Ca²⁺): 8.6–10.2 mg/dL (≈ 2.15–2.55 mmol/L) Ionized Calcium: 4.5–5.3 mg/dL (≈ 1.12–1.32 mmol/L) Magnesium (Mg²⁺): 1.7–2.2 mg/dL (≈ 0.70–0.95 mmol/L) Phosphate (PO₄³⁻): 2.5–4.5 mg/dL (≈ 0.81–1.45 mmol/L) Serum osmolality: 275–295 mOsm/kg Anion gap (depends if K included): typically 8–12 mEq/L (without K) or 10–16 (with K) Albumin: 3.5–5.0 g/dL (relevant because it affects total calcium)
