ECCO - Hemodynamics 1 Questions with Answers (100%
Correct Answers)
Twelve hours after CVC insertion in the right subclavian vein, vital
sign changes from baseline are as noted: peaked airway pressure on
the ventilator increases to 65 cm H2O (H), RR to 30, breath sounds
diminished on the right, and SpO2 92%. Patient reports sudden chest
pain and SOB. For what should the nurse prepare? Answer: Chest tube
insertion
A patient with a radial arterial catheter has a dampened waveform.
The nurse is unable to aspirate blood from the line and notes pallor of
the affected hand but no cyanosis. The nurse should: Answer: Notify
the provider, and prepare to remove the catheter.
What is the main purpose of quickly activating and releasing the flush
device to bounce the waveform into a "square wave" Answer: To
evaluate the dynamic response of the system.
What patient conditions should the nurse consider upon seeing this
arterial pressure waveform? Answer: incorrect: Aortic insufficiency
correct: Constrictive pericarditis

correct: Cardiac tamponade
correct: Pericardial effusion
How can a nurse prevent the most common complication that occurs
with CVCs? Answer: correct: Change IV tubing and dressing per
guidelines
correct: before accessing a port, "scrub the hub" for 15-30 seconds
Ten minutes after a CVC is removed, the patient reports difficulty
breathing and chest pain. BP before removal 126/70, now 80/40. Patient
is slightly cyanotic. Besides notifying the provider, what is initially
indicated? Answer: Place patient in left lateral decubitus and
Trendelenburg position
The result of an Allen's test on the nondominant hand is 16 seconds.
What is the nurse's next step? Answer: Notify provider, and test
