FCCS Pretest & Post
1. A patient suddenly becomes hypotensive, tachycardic, confused, and cool to the touch.
What is the most appropriate initial approach?
A. Obtain a psychiatric consultation
B. Rapidly assess airway, breathing, circulation, and identify reversible causes
C. Wait for laboratory results before intervening
D. Administer a sedative
Answer: B. Rapidly assess airway, breathing, circulation, and identify reversible causes
Rationale: The seriously ill patient requires immediate assessment and stabilization. ABC
evaluation identifies immediately life-threatening problems while simultaneous diagnostic
evaluation searches for reversible causes of shock, respiratory failure, or other critical illness.
2. Which finding is most concerning for impending respiratory failure?
A. Mild tachypnea after walking
B. Increasing work of breathing with altered mental status
C. Respiratory rate of 14/minute
D. Normal oxygen saturation on room air
Answer: B. Increasing work of breathing with altered mental status
Rationale: Increasing respiratory effort combined with altered consciousness suggests the
patient may soon be unable to maintain ventilation or protect the airway. Respiratory failure
should be recognized clinically rather than relying solely on oxygen saturation.
3. What is the primary goal of preoxygenation before emergency intubation?
A. Increase carbon dioxide production
B. Increase oxygen reserves and prolong safe apnea time
C. Reduce blood pressure
D. Cause sedation
Answer: B. Increase oxygen reserves and prolong safe apnea time
,Rationale: Preoxygenation replaces nitrogen in the functional residual capacity with oxygen,
increasing oxygen stores before apnea. This can reduce the risk of severe desaturation during
airway management.
4. Which airway finding should immediately raise concern for a difficult airway?
A. Normal mouth opening
B. Limited neck mobility
C. Normal dentition
D. Clear speech
Answer: B. Limited neck mobility
Rationale: Limited cervical mobility can make airway positioning and visualization more
difficult. Other predictors include limited mouth opening, abnormal anatomy, facial trauma,
obesity, and other factors identified during airway assessment.
5. A patient with severe hypoxemic respiratory failure remains conscious and can protect
the airway. Which intervention may be considered before invasive mechanical ventilation
when clinically appropriate?
A. Noninvasive respiratory support
B. Immediate oral feeding
C. Routine sedation
D. Fluid restriction in every case
Answer: A. Noninvasive respiratory support
Rationale: Noninvasive ventilation or other noninvasive oxygen-delivery strategies may be
appropriate for selected patients with acute respiratory failure. Patient selection is critical;
inability to protect the airway, severe hemodynamic instability, or worsening respiratory failure
may necessitate intubation.
6. What is the principal purpose of positive end-expiratory pressure (PEEP)?
A. Prevent alveolar collapse at end expiration
B. Eliminate carbon dioxide production
C. Reduce hemoglobin concentration
D. Stop cardiac output
Answer: A. Prevent alveolar collapse at end expiration
,Rationale: PEEP maintains positive pressure at the end of expiration, helping recruit and
stabilize alveoli. Appropriate PEEP can improve oxygenation, although excessive PEEP can
impair venous return and cause overdistension.
7. A patient on mechanical ventilation suddenly develops hypotension and unilateral absent
breath sounds. What complication should be suspected?
A. Pulmonary edema
B. Tension pneumothorax
C. Hypoglycemia
D. Metabolic alkalosis
Answer: B. Tension pneumothorax
Rationale: Sudden hypotension with unilateral absent breath sounds in a mechanically ventilated
patient is highly concerning for tension pneumothorax. This is an emergency requiring
immediate treatment rather than waiting for definitive imaging when the clinical picture is
compelling.
8. Which ventilator strategy is central to lung-protective ventilation in acute respiratory
distress syndrome?
A. High tidal volumes based on actual body weight
B. Low tidal volumes based on predicted body weight
C. No PEEP
D. Deliberate severe hyperoxia
Answer: B. Low tidal volumes based on predicted body weight
Rationale: Lung-protective ventilation uses lower tidal volumes based on predicted body weight
to reduce ventilator-induced lung injury. Plateau pressure is also monitored to limit excessive
alveolar distending pressure.
9. Which measurement helps assess the pressure applied to the respiratory system during
mechanical ventilation?
A. Plateau pressure
B. Serum sodium
C. Hemoglobin
D. Blood glucose
, Answer: A. Plateau pressure
Rationale: Plateau pressure is measured during an inspiratory hold when there is no airflow. It
provides information about alveolar pressure and helps guide lung-protective ventilation.
10. A patient has severe respiratory distress, diffuse bilateral infiltrates, and hypoxemia not
fully explained by cardiac failure. Which condition should be considered?
A. ARDS
B. Simple hypertension
C. Migraine
D. Stable angina
Answer: A. ARDS
Rationale: Acute respiratory distress syndrome is characterized by acute hypoxemic respiratory
failure with bilateral pulmonary opacities not fully explained by cardiogenic pulmonary edema
or another isolated cause. Management includes lung-protective ventilation and treatment of the
underlying cause.
11. Which acid-base abnormality is expected with hypoventilation?
A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic alkalosis only
D. Normal carbon dioxide
Answer: A. Respiratory acidosis
Rationale: Hypoventilation reduces carbon dioxide elimination, causing PaCO₂ to rise.
Increased carbon dioxide produces respiratory acidosis. The kidneys can compensate over time
by retaining bicarbonate.
12. A patient is hyperventilating because of severe anxiety. Which acid-base disturbance is
most likely initially?
A. Respiratory alkalosis
B. Respiratory acidosis
C. Metabolic acidosis
D. Metabolic alkalosis
Answer: A. Respiratory alkalosis
