A patient presents to the ER with fulminating pulmonary edema. Which of
the following would be experienced with this emergency?
A. Elevated left ventricular filling pressure with low QT
B. Hypovolemia
C. A good response to supplemental O2
D. CVP 10 torr and PAP 10 torr
A. Elevated left ventricular filling pressure with low QT
Explanation: Fulminating pulmonary edema is a serious condition often
resulting from left-sided heart failure. Left ventricular filling pressure,
a.k.a. pulmonary capillary wedge pressure (PCWP), would likely be
elevated while cardiac output (QT) would drop. The back pressure or
congestion would become relieved in the lungs, creating severe
pulmonary congestion.
,Which of the following conditions would benefit most from a
thoracentesis?
A. Atelectasis
B. Small pneumothorax
C. Complete opacification of the right lung
D. Pericardial contustions
B. Small pneumothorax
Explanation : A thoracentesis is a procedure that removes air or fluid
from the pleural space. This would be appropriate with a small
pneumothorax. A large pneumothorax, however, would require chest
tubes
Which of the following is the best indicator of the adequacy of alveolar
ventilation?
A. Color
B. PaCO2 from an arterial blood gas analysis
C. Tidal Volume
D. Respiratory Rate
B. PaCO2 from an arterial blood gas analysis
Explanation : Adequate alveolar ventilation is best manifest by the
exhalation of CO2 observed on an arterial blood gas. Tidal volume,
respiratory rate, or color are not good indicators of the adequacy of
alveolar ventilation.
A 32-gestational week newborn is receiving mechanical ventilation via a
3.0 mm endotracheal tube. Which of the following are associated with
ongoing assessment of renal function?
A. Humidification is maintained at a non-invasive temperature
B. Diaper weight and blood draw volumes are recorded
,C. PCWP
D. mPAP
B. Diaper weight and blood draw volumes are recorded
Explanation : NPO (nothing by mouth) indicates that a newborn is not
feeding in the usual manner. Intravenous fluids are vital and must be
recorded for an intubated patient. Fluid output is measured by diaper
weight and carefully recorded blood draws. Humidification of gas
through the endotracheal tube must be maintained at an invasive
temperature rather than a noninvasive because the nasal passages are
bypassed.
A patient with ARDS and asthma could benefit from which of the
following medications?
A. cromolyn sodium
B. exogenous surfactant
C. Tobramycin and albuterol
D. Spiriva and decadron
B. exogenous surfactant
Explanation : A patient with adult respiratory distress syndrome could
benefit from surfactant therapy to decrease the surface tension of the
alveoli.
The respiratory therapist should look to which of the following clinical
data to determine the effectiveness of incentive spirometry?
A. Breath sounds before and after every treatment
B. Maximum voluntary ventilation done periodically
C. Inspiratory capacity predicted volume
D. Arterial blood gas analysis pre and post treatment
, A. Breath sounds before and after every treatment
Explanation : The effectiveness of incentive spirometry can best be
determined by auscultating breath sounds before and after the
treatment and noting changes in air movement. While achieving
inspiratory capacity is the goal, the real goal is to increase lung volume,
improve alveolar recruitment, and prevent consolidation of sputum in
the lungs.
A patient with a tracheostomy is receiving supplemental oxygen via
tracheostomy collar connected to a large volume nebulizer set at 40%.
The respiratory therapist analyzes the FIO2 at the tracheostomy collar
with a galvanic fuel cell analyzer. The analysis shows the FIO2 to be 55%.
Which of the following could be the cause of the increase in FIO2?
A. calibration error in the galvanic fuel cell
B. the aerosol tubing is too short
C. clogged jet orifice in the nebulizer
D. too much water in the circuit
D. too much water in the circuit
Explanation : When administering oxygen by any device that has a
venturi mechanism, back pressure on the venturi will slow the speed of
gas, decrease room air entrainment, and result in an increase in FIO2. Of
the options offered, only excess water in the tubing would cause this
type of back pressure.
A patient receiving volume-controlled ventilation in SIMV mode has a
total respiratory rate of 26/min and is showing signs of increased labor of
breathing. The mandatory rate is 14/min. Which of the following would
most likely help the patient?
A. Increase the machine flow rate
