1. A new patient was admitted and has been diagnosed with

pneumonia. The patient has an oxygen saturation of 87% on 2

L/min nasal cannula. Which of the following would cause the

patient to be hypoxemic?

1. Capillary shunting

2. Diffusion defect

3. Alveolar consolidation

4. Hypoventilation

Select all that apply:

A. 1 and 2

B. 2 and 3

C. 1 and 3

D. All of the above

To get this one right, you have to have a basic understanding of

pneumonia. For the TMC Exam, I want you to always remember

that consolidation is associated with pneumonia.

So automatically we know that alveolar consolidation is one of the

correct answers. Hypoxemia in pneumonia patients is also related

to capillary shunting as well. That is because, if the alveoli are filled

with fluid (consolidation), perfusion will not occur as the oxygen

passes through, causing hypoxemia.

A diffusion defect is found in patients with pulmonary fibrosis—

not pneumonia. Patients with pneumonia will show signs of

hyperventilation, not hypoventilation, so we can rule that one out

as well.

So by using what we know about pneumonia, as well as the

process of elimination, we know that the correct answer has to be

C.

The correct answer is: C. 1 and 3

2. A 16-year-old patient has been admitted and shows signs of

poor body development. Upon assessment, you also noted

digital clubbing, hyperresonance to percussion, and a

productive cough. It has also been reported that the patient

has foul-smelling stools. Which of the following conditions are

these findings consistent with?

A. Acute respiratory distress syndrome

B. Heart failure

C. Acute bronchitis

D. Cystic fibrosis

If you’ve studied up on your pathology, you should know right

away that this patient is showing signs of cystic fibrosis.

Cystic fibrosis patients typically show signs of poor body

development, malnourishment, and foul-smelling stools. They

usually have a productive cough with large amounts of secretions.

Digital clubbing is a sign of chronic hypoxemia, which can be seen

in cystic fibrosis as well.

Also, you should remember that cystic fibrosis is an obstructive

lung disease. We know that air trapping is a side effect of

obstructive diseases, and that is what causes the hyperresonant

percussion note to be heard.

None of the other answer choices make sense in this situation, so

we know that the correct answer has to be D.

The correct answer is: D. Cystic fibrosis

3. While reviewing the chest x-ray of a 57-year-old male patient,

you noted blunting of the left costophrenic angle. It also states
