Question 1

A patient in cardiogenic shock has a cardiac output of 2 L/min and elevated pulmonary artery wedge pressure (PAWP). Which drug class is most appropriate?

Accepted Answer

Inotropes such as dobutamine

Answer

Dobutamine increases myocardial contractility and cardiac output in cardiogenic shock without significantly increasing afterload.

Question 2

A nurse is caring for a patient on continuous renal replacement therapy (CRRT). The circuit clots frequently. Which intervention is most appropriate?

Accepted Answer

Increase blood flow rate and review anticoagulation protocol

Answer

Increasing blood flow rate and optimizing anticoagulation (e.g., heparin or citrate) prevents circuit clotting in CRRT.

Question 3

A mechanically ventilated patient's ABG shows: pH 7.50, PaCO2 28 mmHg, HCO3 22 mEq/L. How should the ventilator be adjusted?

Accepted Answer

Decrease respiratory rate or tidal volume

Answer

The ABG indicates respiratory alkalosis from hyperventilation; decreasing respiratory rate or tidal volume will normalize PaCO2.

Question 4

Which early sign of septic shock differentiates it from other forms of shock?

Accepted Answer

Warm, flushed skin with high cardiac output (hyperdynamic state)

Answer

Early septic shock is characterized by a hyperdynamic state with vasodilation, warm skin, and elevated cardiac output.

Question 5

A patient with a traumatic brain injury has a sudden drop in GCS from 12 to 7 and one dilated fixed pupil. What does this indicate?

Accepted Answer

Uncal herniation with ipsilateral cranial nerve III compression

Answer

A unilateral dilated fixed pupil with decreasing GCS in head trauma indicates uncal herniation compressing CN III.
