Q

Management for pt with Inferior wall ST elevations, JVD, parasternal lift, and clear lungs? Management?

A

MI with RV involvement

  1. Preload dependent - give fluid (lung crackling suggests too much)
  2. Give pressors if hypotensive

Q

CHF with BP 160/90, pulse 110, BUN 60, Cr 2.3 - management?

A
