A change in the PA waveform and pressure are noted. A dicrotic
notch is no longer visible. Values change from 36/15 to 30/3. What
action should the nurse anticipate? - answer ?Removing the syringe
from the balloon port.
A sudden drop in the waveform's values, accompanied by a loss of
the dicrotic notch, could indicate catheter slippage from PA to RV.
, Inflating the balloon may help the catheter float forward into the PA.
Notify the provider for possible catheter repositioning.
A patient with septic shock is hypotensive and his ScvO2 trended
from 72% to 85% over the last hour. Norepinephrine and
vasopressin (Pitressin) are at high dose. Which interventions do you
anticipate? - answer Notify provider..
Assess temperature..
Hypothermia and tissue extraction failure are both possible causes
of increasing ScvO2
A patient with dilated cardiomyopathy asks the nurse why
dobutamine was ordered. The nurse's best response is: - answer It
improves the pumping action of your heart.
Measure the PAP shown on the waveform. The patient is on
mechanical ventilation. - answer 24/14
Measure peak systole and end-diastole for a mechanically ventilated
patients at end-expiration - usually the low point in the tracing just
before the next positive pressure breath pushes the waveform
tracing upward.
A nurse observes the new onset of giant V waves in the PAOP
waveform of a patient who is post-MI. What is the clinical
significance? - answer Papillary muscle rupture
The abrupt onset of mitral insufficiency due to papillary muscle
rupture is associated with large increase in the amplitude of the V
wave in the PAOP waveform.
