NBRC Practice Exam 11 and 2 only - questions and answersWhich of the following would be observed on a patient with
cor pulmonale?
1. Pedal edema
2. Jugular venous distention
3. Decreased CVP level
1 only - questions and answersThe RT is reviewing the chart of a 38-year-old woman who
presented in ED two hours ago complaining of shortness of breath. A CBC reveals a
hemoglobin level of 6 gm/dL and her SpO2 is 98%. Which of the following statements are true
regarding this patient's condition?
1. The patient is hypoxic
2. The patient is most likely cyanotic
3. Oxygen is not indicated at this time
1, 3, and 4 only - questions and answersThe patient's chart indicates a potassium level of 2.0
mEq/L. Which of the following would you expect to observe with this patient?
1. Muscle weakness
2. Respiratory alkalosis
3. Metabolic alkalosis
4. Cardiac arrhythmias
1, 3, and 4 only - questions and answersWhile assessing a patient's chest radiograph the RT
observes an area of hyperlucency. This may be the result of which of the following?
1. Hyperinflation
2. Atelectasis
3. Emphysema
4. Pneumothorax
Coarse crackles - questions and answersDuring the 24 hours following gastric resection, a
48-year-old woman received continuous IV infusions. Blood chemistry results indicate

Fully compensated respiratory alkalosis, mild hypoxemia - questions and answersThe RT is
reviewing ABGs obtained earlier in the day from a patient on a 35% air-entrainment mask. The
ABG values are as follows:
pH - 7.43
PaCO2 - 29 torr
PaO2 - 70 torr
HCO3 - 18 mEq/L
BE - -6 mEq/L
The correct interpretation of these ABGs is which of the following?
A. Partially compensated metabolic acidosis, normal oxygenation
B. Fully compensated respiratory alkalosis, mild hypoxemia
C. Uncompensated respiratory alkalosis, normal oxygenation
D. Fully compensated metabolic acidosis, mild hypoxemia

A. Has pulmonary edema
B. Has inadequate perfusion to the extremities
C. Has adequate pulmonary perfusion

A. Obstructive apnea
B. Hypoventilation
C. The lungs are becoming easier to ventilate
D. Lung compliance is increasing
Pneumothorax - questions and answersThe RT notes in a ventilator's patient's chart that chest
percussion resulted in an area of hyperresonance over the right chest area. This percussion
note is most likely the result of which of the following?
A. Pneumothorax
B. Atelectasis
C. Consolidation
D. Pulmonary edema
