1. A 48-year-old female is admitted to the ED with
diaphoresis, jugular venous distension, and 3+ pitting edema
in the ankles. These findings are consistent with:
A. Liver failure
B. Pulmonary embolism
C. Heart failure
D. Electrolyte imbalances
Correct Answer: C. Heart failure
Rationale: The classic triad of diaphoresis (sympathetic response),
jugular venous distension (elevated central venous pressure), and
1
,peripheral edema (fluid retention) strongly indicates heart failure.
The JVD reflects increased right heart pressures, while the edema
results from venous congestion and fluid extravasation .
2. A patient with ARDS is receiving mechanical ventilatory
support. An end-tidal CO₂ monitor shows a PetCO₂ of 59 torr.
The therapist should:
A. Increase minute ventilation
B. Obtain an arterial blood gas
C. Recalibrate the capnography
D. Continue current therapy and ventilator settings
Correct Answer: B. Obtain an arterial blood gas
*Rationale: An elevated PetCO₂ (normal 35-45 torr) indicates
possible hypoventilation, but the correlation between PetCO₂
and PaCO₂ can be unreliable in ARDS due to V/Q mismatch and
2
,dead space. An ABG should be obtained to confirm the actual
PaCO₂ before making ventilator changes .*
3. A patient presents with absent breath sounds on the left
side, hyperresonance to percussion, tracheal deviation to the
right, and hypotension. What is the most appropriate
immediate action?
A. Obtain a chest X-ray
B. Insert a needle in the 2nd intercostal space on the left
C. Administer IV fluids
D. Perform a thoracentesis
Correct Answer: B. Insert a needle in the 2nd intercostal space
on the left
*Rationale: These findings are classic for tension pneumothorax:
absent breath sounds and hyperresonance on the affected side,
3
, tracheal deviation away from the tension (to the right), and
hypotension from decreased venous return. Needle
decompression at the 2nd intercostal space, midclavicular line on
the affected side is the immediate life-saving intervention .*
4. Which of the following parameters indicates a patient is
ready to wean from mechanical ventilation?
A. A-aDO₂ of 410 mm Hg
B. PEEP of 10 cm H₂O
C. Pulmonary shunt of 16%
D. MIP of -18 cm H₂O
Correct Answer: C. Pulmonary shunt of 16%
*Rationale: A shunt fraction <20% is generally considered
acceptable for weaning. An A-a gradient of 410 mmHg is
elevated (normal 5-15 mmHg), indicating poor oxygenation.
