Nível	Frente (Pergunta / Termo)	Verso (Resposta / Explicação)
basic	What are the normal adult serum reference ranges for Sodium (Na+), Potassium (K+), Chloride (Cl-), and Bicarbonate (HCO3-)?	Sodium (Na+): 135–145 mEq/L; Potassium (K+): 3.5–5.0 mEq/L; Chloride (Cl-): 96–106 mEq/L; Serum Bicarbonate (total CO2/HCO3-): 22–28 mEq/L.
basic	What are the normal adult serum reference ranges for Total Calcium (Ca2+), Ionized Calcium, Magnesium (Mg2+), and Phosphate (PO4-)?	Total Calcium: 8.5–10.5 mg/dL (9.0–10.5 mg/dL); Ionized Calcium: 4.5–5.6 mg/dL (1.12–1.40 mmol/L); Magnesium: 1.5–2.5 mEq/L (1.8–2.6 mg/dL); Inorganic Phosphate: 2.5–4.5 mg/dL.
basic	What are the normal adult reference ranges for Red Blood Cell (RBC) count, Hemoglobin (Hgb), and Hematocrit (Hct) in males versus females?	Males: RBC 4.5–5.9 million/mm³, Hemoglobin 13.5–17.5 g/dL, Hematocrit 41–50%; Females: RBC 4.0–5.2 million/mm³, Hemoglobin 12.0–16.0 g/dL, Hematocrit 36–46% (Note: Hematocrit is roughly 3 times the Hemoglobin value).
basic	What is the normal reference range for Mean Corpuscular Volume (MCV), and what are the differential diagnoses for Microcytic (< 80 fL), Normocytic (80–100 fL), and Macrocytic (> 100 fL) anemias?	Normal MCV: 80–100 fL. Microcytic (< 80 fL, 'TAILS'): Thalassemia, Anemia of chronic disease (late), Iron deficiency, Lead poisoning, Sideroblastic anemia; Normocytic (80–100 fL): acute blood loss, early anemia of chronic disease, CKD (low EPO), aplastic anemia, hemolysis (sickle cell, G6PD, hereditary spherocytosis); Macrocytic (> 100 fL): Megaloblastic (Vitamin B12 or Folate deficiency with hypersegmented neutrophils) vs. Non-megaloblastic (alcoholism, liver disease, hypothyroidism, reticulocytosis).
intermediate	What are the normal sea-level Arterial Blood Gas (ABG) reference ranges for pH, PaCO2, HCO3-, PaO2, SaO2, and Base Excess?	pH: 7.35–7.45 (strict midpoint 7.40); PaCO2: 35–45 mmHg (midpoint 40 mmHg); HCO3-: 22–26 mEq/L (midpoint 24 mEq/L); PaO2: 80–100 mmHg; SaO2: 95%–100%; Base Excess (BE): -2 to +2 mEq/L.
intermediate	How do Venous Blood Gas (VBG) values compare to Arterial Blood Gas (ABG) values in a hemodynamically stable patient?	Peripheral VBG pH is ~0.03–0.04 units lower than ABG pH (normal VBG pH ~7.31–7.41), PvCO2 is ~4–6 mmHg higher (normal ~40–50 mmHg), and venous HCO3- is within ~1–2 mEq/L of arterial HCO3-; however, PvO2 (~35–45 mmHg) CANNOT be used to assess arterial oxygenation.
intermediate	On standard ECG paper running at 25 mm/sec with 10 mm/mV calibration, what time duration and voltage amplitude correspond to 1 small box (1 mm) and 1 large box (5 mm)?	Horizontal axis (time): 1 small box (1 mm) = 0.04 seconds (40 ms); 1 large box (5 small boxes) = 0.20 seconds (200 ms); 5 large boxes = 1.0 second; Vertical axis (voltage): 1 small box = 0.1 mV; 2 large boxes (10 mm) = 1.0 mV.
intermediate	How do you rapidly estimate Heart Rate on a regular rhythm strip (the '300-150-100-75-60-50' rule) versus an irregular rhythm strip (the '6-second strip' method)?	For a REGULAR rhythm: divide 300 by the number of large boxes between two consecutive R waves (1 box = 300 bpm, 2 = 150, 3 = 100, 4 = 75, 5 = 60, 6 = 50), or divide 1,500 by the number of small boxes; for an IRREGULAR rhythm (such as Atrial Fibrillation): count the number of R waves in a 6-second strip (30 large boxes) and multiply by 10.
advanced	What are the narrow therapeutic serum reference ranges and toxic thresholds for Lithium, Digoxin, and Theophylline?	Lithium: 0.6–1.2 mEq/L (acute mania 0.8–1.2 mEq/L, maintenance 0.6–1.0 mEq/L; toxic > 1.5 mEq/L; severe/dialyzable > 2.5 mEq/L); Digoxin: 0.5–2.0 ng/mL (specifically 0.5–0.9 ng/mL in Heart Failure, 0.8–2.0 ng/mL in AFib; toxic > 2.0 ng/mL); Theophylline: 10–20 mcg/mL (often targeted at 5–15 mcg/mL; toxic > 20 mcg/mL).
advanced	What are the therapeutic serum reference ranges for the antiepileptic drugs Phenytoin (Total and Free), Valproic Acid, Carbamazepine, and Phenobarbital?	Total Phenytoin: 10–20 mcg/mL (Free/Unbound Phenytoin: 1.0–2.0 mcg/mL); Valproic Acid (Valproate): 50–100 mcg/mL (up to 125 mcg/mL in mania); Carbamazepine: 4–12 mcg/mL; Phenobarbital: 15–40 mcg/mL.
advanced	How do you calculate Mean Arterial Pressure (MAP), what is its normal range, and what is the minimum MAP target required to maintain vital organ (cerebral, coronary, renal) perfusion in shock?	MAP = [(2 × Diastolic BP) + Systolic BP] / 3, or Diastolic BP + 1/3(Pulse Pressure); normal MAP is 70–100 mmHg, and the minimum resuscitation target in shock/sepsis is MAP >= 65 mmHg.
advanced	Where should the Phlebostatic Axis transducer be leveled when zeroing an Arterial Line or Central Venous / Pulmonary Artery Catheter, and how does transducer malpositioning affect pressure readings?	Level the transducer stopcock at the Phlebostatic Axis: the intersection of the 4th intercostal space and the mid-axillary line (corresponding to the anatomical level of the right atrium); if the transducer is positioned TOO LOW (below the right atrium), hydrostatic weight produces a FALSELY HIGH pressure reading; if the transducer is positioned TOO HIGH (above the right atrium), it produces a FALSELY LOW pressure reading.
