A respiratory therapist should recommend
A.
changing to SIMV mode.
B.
increasing to 10 cm H2O PEEP.
C.
changing to 5 cm H2O CPAP.

,D.
increasing to 400 mL VT. - answer✔✔B. √
increasing to 10 cm H2O PEEP.
EXPLANATIONS
(h) A. Changing to SIMV will not treat the hypoxemia. It may also cause a decrease in minute
ventilation and adverse changes in the acid-base status.
(c) B. The increase in PEEP will increase FRC, decrease the intrapulmonary shunt, and address
the hypoxemia.
(h) C. Changing to CPAP may decrease minute ventilation causing adverse changes in the acid-
base status.
(u) D. Increasing the tidal volume will further decrease the PaCO2. It will not significantly
improve oxygenation.
When instructing a patient on the administration of umeclidinium/vilanterol (Anoro Ellipta),
which of the following is most important to emphasize?

Gargle immediately after use.
B.
Inhale slowly with a breath hold.
C.
Breathe in fast and deep.
D.

,(u) A. Umeclidinium/vilanterol (Anoro Ellipta) is not an inhaled steroid and, thus, does not
require gargling after use.
(u) B. Umeclidinium/vilanterol (Anoro Ellipta) is a DPI that requires rapid inhalation.
(c) C. Breathing in fast and deep is the proper method of administration for
umeclidinium/vilanterol (Anoro Ellipta).
(u) D. Umeclidinium/vilanterol (Anoro Ellipta) is a DPI and does not require shaking before use.
Following placement of a tracheostomy tube for long-term mechanical ventilation, which of the
following patient positions best prevents ventilator-associated pneumonia?
(h) A. Prone positioning is contraindicated following tracheostomy placement.
(h) B. Use of Trendelenburg positioning may increase the risk of aspiration.
(u) C. A decreased incidence of ventilator-associated pneumonia has been observed with an
elevated head of bed as compared to supine.
EXAM STUDY MATERIALS July 23, 2024 4:26 PM
, (c) D. Routine use of semi-Fowler positioning with the head of the bed elevated at an angle of
30-45 degrees has been shown to decrease rates of ventilator-associated pneumonia.
Which of the following is used to monitor the partial pressure of transcutaneous carbon dioxide?
A.
red-light absorption sensor
B.
electromechanical transducer
C.
infrared analyzer
D.
(u) A. A red-light absorption sensor is used in a pulse oximeter.
(u) B. An electromechanical transducer measures airway pressure.
(u) C. An infrared analyzer is used in a capnometer.
(c) D. A Stow-Severinghaus blood gas electrode is used in transcutaneous monitors.
An adult patient requires frequent blood sampling and medication administrations through an IV
for 1 month. The preferred vascular access is a
