Q

most sensitive indicator of MI

Troponin I

62
Q

chest Xray

A
  • Heart will look white and take up no more than 1/3 of the xray
  • See size, lung fields, plaque
  • for xray: need to know if they’re pregnant, have metal anywhere, allergies to iodine, know which tests have contrast or not, kidney function if contrast; if ESRD- can’t filter die, could be toxic and cause fluid overload, know which test they need to be NPO on, or not have stimulants, know weight
63
Q

  • Blood Pool Imaging, ejection fraction study, MUGA

- Assists in assessing the “pumping action” of the heart

64
Q

normal ejection fraction

A

55%-65%

65
Q

cardiac cath care (post op)

A

Post op for cardiac cath pts: procedure can dislodge the plaque: assess for s/s of clots (s/s of stroke, MI), pneumothorax (breath sounds, know baseline O2 and keep eye on it) aspiration (pts aren’t always honest about being NPO), hemorrhage (look behind them), sedation (put them on their sides so their tongues don’t fall back)

66
Q

tracheostomy complications

A
  • Complications include bleeding, pneumothorax, aspiration, subcutaneous or mediastinal emphysema, laryngeal nerve damage, posterior tracheal wall penetration.
  • Long-term complications include airway obstruction, infection, rupture of the innominate artery, dysphagia, fistula formation, tracheal dilatation, and tracheal ischemia and necrosis.
