Study Guide CC 1 Final Exam 2023

When a patient fails to ventilate or oxygenate adequately, the problem is caused by pathophysiological factors

such as hyperventilation.

• True

• False

When looking at the pressure-volume loop, a shift of the slope toward the pressure axis indicates a decrease in

compliance.

• True

• False

One of the most common causes of increased airway resistance is COPD.

• True

• False

During spontaneous ventilation, the diaphragm and other respiratory muscles create gas flow by raising the

pleural, alveolar, and airway pressures.

• True

• False

Positive pressure ventilation causes an increase in intrathoracic pressure and compression of the pulmonary

blood vessels leading to an overall decrease in ventricular output, stroke volume, and pressure readings.

• True

• False

Sustained hyperventilation of less than 24 hours causes respiratory alkalosis and increases cerebral blood flow

and intracranial pressure.

• True

• False

In PCV CMV the rate, TI or I:E ratio are set by the operator.

• True

• False

When looking at the pressure-volume loop, a decrease in CLT will not affect the PTA.

• True

• False

When compared to more frequent circuit changes, weekly circuit change does not increase the incidence of

nosocomial infection, including ventilator-associated pneumonia.

• True

• False

The concentrated source of energy in fat emulsion is preferred for fluid-restricted patients.

• True

• False
