CH 17: Respiratory

A person who experiences sharp chest pain followed by increasing dyspnea after coughing likely has:

a pneumothorax

You should reserve oxygen concentrations higher than which percentage for patients with hypoxia who do not respond to lower concentrations?

50%

To generate the optimal particle size, most nebulizers need to have a gas flow of at least:

6 L/min.

Why are children more prone to croup when they acquire a viral infection than adults infected with the same virus?

A child's airway is narrower than an adult's, and even minor swelling can result in obstruction.

What type of medication can cause thick sputum?

Antihistamine

Quiet tachypnea suggests possible

Shock

Orthopnea

ability to breathe only in an upright position

The main stem bronchus ends at the level of the

Polycythemia is a condition in which

excess red blood cells are produced in response to chronic hypoxia.

The body's immediate response to mild hypoxemia is

increased heart rate.

Paroxysmal nocturnal dyspnea may be a sign of

left-side heart failure.

Difficulty with exhalation is most characteristic of:

obstructive lung disease

Patients with pneumonia often experience a coughing fit when they roll from one side to the other because

pneumonia often occurs in the lung bases, typically on only one side.

A patient's peripheral pulses become extremely weak during inhalation. This is called

pulsus paradoxus.

Cor pulmonale is defined as:

right heart failure secondary to chronic lung disease.
