  1. A patient with diabetic ketoacidosis has a serum potassium of 5.8 mEq/L. Why must potassium be monitored closely during insulin therapy?

    Answer: Insulin drives potassium into cells, causing rapid hypokalemia

    Insulin shifts potassium intracellularly, so serum levels can fall quickly during DKA treatment.

  2. Which ECG change is the earliest sign of hyperkalemia?

    Answer: Peaked T waves

    Tall, peaked T waves are the earliest ECG manifestation of hyperkalemia.

  3. A patient with increased intracranial pressure shows Cushing's triad. Which set of vital signs reflects this?

    Answer: Hypertension, bradycardia, irregular respirations

    Cushing's triad is hypertension with widened pulse pressure, bradycardia, and irregular respirations.

  4. What is the primary goal when managing a patient with acute respiratory distress syndrome on the ventilator?

    Answer: Low tidal volume lung-protective ventilation

    Low tidal volume (6 mL/kg) ventilation reduces ventilator-induced lung injury in ARDS.

  5. A post-operative patient has a sudden drop in blood pressure, tachycardia, and cool clammy skin. Which type of shock is most likely?

    Answer: Hypovolemic shock

    Hemorrhage causing hypovolemia presents with hypotension, tachycardia, and cool clammy skin.

  6. Which lab value is most specific for myocardial cell injury?

    Answer: Troponin I

    Troponin I is the most cardiac-specific and sensitive marker of myocardial injury.

  7. A patient with severe sepsis has a lactate of 4.5 mmol/L. What does this elevated lactate indicate?

    Answer: Tissue hypoperfusion and anaerobic metabolism

    Elevated lactate reflects anaerobic metabolism from tissue hypoperfusion in sepsis.
