1
Q

s/s

A
  • muffled heart sounds on auscultation
  • narrow pulse pressure
  • jugular vein distention
  • pulse paradoxus (systolic drop in bp 15 during inspiration)
  • restlessness
  • upright leaning forward posture
2
Q

key test results

A

*CXR (slightly widened mediastinum & cardiomegaly
*echocardiography records pericardial effusion w/signs of
right ventricular and atrial compression
*ECG used to rule out other cardiac d/o-not useful to
diagnose cardiac tamponade

3
Q

key treatments

A
  • surgery: pericardiocentesis or thoracotomy
  • andrenergic agent: epinephrine
  • inotropic agent: dopamine
4
Q

key interventions: pericardiocenthesis

A

*keep pericardial aspiration needle attached to a 50 ml
syringe by a three-way stopcock, ECG machine, and
emergency cart w/defibrillator at bedside
*equipment turned on and working
*monitor bp & cVp during and after procedure for
hypotension (indicates cardiac chamber puncture)
*watch for complications: ventricular fibrillation, vasovagul
response, coronary artery or cardiac chamber puncture

5
Q

key interventions: thoracotomy

A

*explain procedure to pt.
*what to expect post op: chest tubes, drainage system,
o2 admin
*teach how to turn, deep-breath, and cough
*maintain chest tube drainage system and be alert for
hemorrhage and arrhythmias
