Week 4 BSN 445 Exam Questions With Complete Solutions
14. Which measurement reading would indicate that the
pulmonary artery catheter is within the right atrium?
2 mmHg
6 mmHg
20/2 mmHg
25/10 mmHg
2 mmHg
Normal mean pressure in the right atrium is 2 to 5 mmHg.
15. The nurse is caring for a mechanically ventilated patient
with a pulmonary artery catheter. To ensure accuracy, at which
point would the nurse assess the pulmonary artery diastolic
pressure (PADP)?
During inhalation
During exhalation
At any point in the respiratory cycle
At the end of expiration
At the end of expiration
To minimize the effect of respiratory variation, the PADP is
read at end-expiration, which is the most stable point in the
respiratory cycle when intrapleural pressures are close to zero.
,16. The nurse is caring for a patient with a pulmonary artery
catheter in place and notes the catheter has spontaneously
migrated to the wedge position. Which action would the nurse
take next?
Inflate the balloon
Ask the patient to lay flat on their back
Slightly pull back on the pulmonary artery catheter
Remove the pulmonary artery catheter
Slightly pull back on the pulmonary artery catheter
The nurse would slightly pull back on the pulmonary artery
catheter to remove it from the wedge position.
17. Which statement accurately describes catheters used to
measure venous oxygen saturation?
Svo2 catheter readings are slightly higher.
An Scvo2 catheter is incorporated into a pulmonary artery
line.
Only a Svo2 catheter requires calibration.
A venous blood sample can be used for recalibration.
A venous blood sample can be used for recalibration.
To recalibrate the fiberoptic module, a venous blood sample
must be withdrawn from the appropriate catheter tip and sent to
the laboratory for oxygen saturation analysis.
18. Which condition would increase the SvO2?
,Acute respiratory distress syndrome
Endotracheal suctioning
Decreased respiratory rate
Supplemental oxygen administration
Supplemental oxygen administration
Administration of supplemental oxygen would increase the
Svo2.
19. Which nursing activity would alter the Svo2 the most?
Dressing change
Physical examination
Chest physiotherapy
Position changes
Chest physiotherapy
20. Where would the nurse place the probe when utilizing the
ClearSight system?
Chest
Neck
Forehead
Finger
Finger
The ClearSight is a pulse contour system that uses a probe
placed on the finger.
, 21. Which intervention would the nurse include in the plan of
care for a patient with an arterial pulse analysis hemodynamic
monitoring system?
Calibrate the system every eight hours
Assess cardiac output every six hours using thermodilution
Ensure the transducer is level to the phlebostatic axis
Increase sedation until the patient tolerates the system
Ensure the transducer is level to the phlebostatic axis
The transducer must be leveled to the phlebostatic axis for
accurate readings.
22. A patient with which condition would benefit from a
transpulmonary thermodilution monitoring system?
Acute respiratory distress syndrome
Post-operative from coronary artery bypass grafting
Asthma
Hypovolemic shock
Acute respiratory distress syndrome
A transpulmonary thermodilution monitoring system can
measure extravascular lung water index, which is useful when
assessing patients with acute respiratory distress syndrome.
1. Which action would the nurse take when preparing a patient
for electrocardiography electrode placement?
Clean the area with hydrogen peroxide
