A

Atropine 0.5mg

27
Q

A

2-10mcg/kg/min

28
Q

A pt. has an onset of dizziness. The pt.s heart rate is 180, BP is 110/70, resp. rate is 18, O2 sat is 98%. This is a reg narrow complex tach rhythm. What is the next intervention?

A

Vagal maneuver.

29
Q

A monitored pt. in the ICU developed a sudden onset of narrow complex tach at a rate of 220/min. The pt’s BP is 128/58, the PETCO2 is 38mm Hg, and the O2 sat is 98%. There is an EJ established for vascular access. The pt. denies taking any vasodialators. A 12 lead shows no ischemia or infarction. Vagal maneuvers are ineffective. What is the next intervention?

A

Adenosine 12mg IV

30

Choose an appropriate indication to stop or withhold resuscitative efforts.

A

Evidence of rigor mortis.

32
Q

A 49 y/o female arrives in the ER with persistent epigastric pain. She has been taking antacids PO for the past 6 hours because she had heartburn. BP is 118/72, heart rate is 92/min, resp. rate is 14 non-labored and O2 sat is 96%. What is the most appropriate next action?

A
