Practice & Quizzes

Drill arterial blood gas pattern recognition — read a fresh pH/PaCO₂/HCO₃ panel each round and name the primary acid-base disorder, with an instant rationale and scored ten-question rounds.

Drill pulmonary function test interpretation — read FEV₁, FVC, FEV₁/FVC, and TLC each round and name the pattern (obstructive, restrictive, mixed, or normal), with an instant rationale and scored ten-question rounds.

Drill oxygenation severity — read a PaO₂ and FiO₂ each round, compute the P/F ratio, and classify the Berlin ARDS band (none, mild, moderate, or severe), with an instant rationale and scored ten-question rounds.

Drill shock classification — read a hemodynamic profile (CVP, PCWP, cardiac output, SVR) each round and name the shock category (hypovolemic, cardiogenic, obstructive, or distributive), with an instant rationale and scored ten-question rounds.

Drill the harder half of ABG interpretation — read a pH/PaCO₂/HCO₃ panel each round and judge the compensation status (uncompensated, partially compensated, fully compensated, or a mixed disorder), with an instant rationale and scored ten-question rounds.

Read fresh pressure, flow, and volume scalars each round and name the pattern — normal, increased airway resistance, decreased compliance, auto-PEEP, circuit/cuff leak, or flow starvation — with an instant rationale, the alarm each triggers, and scored ten-question rounds.

Drill Venturi mask math — read a fresh FiO₂ (and O₂ flow) each round and compute the air-to-oxygen entrainment ratio or the total delivered flow from the formula, with an instant rationale and scored ten-question rounds.

Drill EtCO₂ capnogram interpretation — read a fresh CO₂ waveform each round and name the pattern (normal, hypoventilation, hyperventilation, shark-fin obstruction, curare cleft, rebreathing, esophageal/absent, sudden loss, or ROSC), with an instant rationale and scored ten-question rounds.

Drill the interpretation-to-intervention step — read a fresh arterial blood gas and the current ventilator settings each round and pick the single best change (rate, FiO₂, or PEEP), with an instant rationale and scored ten-question rounds.

Ten free NBRC TMC-style questions spanning all three matrix categories — patient data, equipment troubleshooting, and initiation & modification — across mechanical ventilation, ABG & acid-base, oxygen therapy, pharmacology, and airway, each with a rationale for every option.
