Build a 'Must-Know NCLEX Lab Values' cheat-sheet / rapid-review content page for the brand 'NursePrep', designed to be saved and shared (include Save and Share actions). Reproduce these exact values. Eyebrow: 'Rapid Review'. H1: 'Must-Know NCLEX Lab Values'. Subtitle: 'A quick-reference guide to essential lab values with normal ranges and clinical nursing implications. Bookmark this page for your final review.' Scannable category cards, each value with a one-line nursing implication: ELECTROLYTES — Sodium (Na) 136–145 mEq/L (assess fluid balance; hyponatremia causes confusion, seizures); Potassium (K) 3.5–5.0 mEq/L (monitor cardiac rhythm; both hyper- and hypokalemia cause dysrhythmias); Calcium (Ca) 8.5–10.5 mg/dL (check Chvostek/Trousseau; hypocalcemia causes tetany); Magnesium (Mg) 1.5–2.5 mEq/L (assess deep tendon reflexes; low Mg potentiates digoxin toxicity). CBC — Hemoglobin (Hgb) M 13.5–17.5 / F 12–16 g/dL (low = anemia); Hematocrit (Hct) M 38–50 / F 36–44 % (elevated may signal dehydration); WBC 4,500–11,000 /mm³ (elevated suggests infection); Platelets (PLT) 150,000–400,000 /mm³ (low = bleeding risk; avoid IM injections, use soft toothbrush). COAGULATION — PT 11–13.5 seconds (monitors warfarin); INR 0.8–1.2 (therapeutic 2–3; >3 hold warfarin and notify provider); aPTT 25–35 seconds (monitors heparin; therapeutic goal 1.5–2.5× baseline). ABGs — pH 7.35–7.45 (below = acidosis, above = alkalosis); PaCO2 35–45 mmHg (elevated = hypoventilation/respiratory acidosis); HCO3 22–26 mEq/L (low with low pH = metabolic acidosis). RENAL — BUN 10–20 mg/dL (elevated may indicate dehydration, GI bleeding, renal dysfunction); Creatinine (Cr) 0.6–1.2 mg/dL (most specific renal marker). A 'Critical Values — Act Now' table: Potassium <2.5 or >6.5 (obtain ECG immediately, prepare for IV replacement or kayexalate); Sodium <120 or >160 (assess neuro status, correct slowly to prevent cerebral edema); Glucose <50 or >400 (treat hypoglycemia with 15 g fast carbs; hyperglycemia may need IV insulin); pH <7.20 or >7.60 (life-threatening; prepare for respiratory support and code cart); Platelets (critical low, high bleeding risk). Include the ROME mnemonic for ABG interpretation (Respiratory Opposite, Metabolic Equal). Exactly ONE soft CTA: 'Get the full set of nursing cheat sheets in the app — start free.'
