1. A patient is in cardiac arrest. The cardiac monitor shows asystole. In addition to providing continuous high-quality CPR, what is the other priority intervention for this patient? - Administering epinephrine as early as possible 2. A patient has experienced return of spontaneous circulation (ROSC) after cardiac arrest. The healthcare team is conducting a secondary assessment to determine the possible cause of the patient's cardiac arrest. Before the arrest, the patient exhibited jugul...

To determine whether there is a delay in impulse conduction through the ventricles, the nurse will measure the duration of the patient's: A) p wave B) q wave C) pr interval D) qrs complex D) qrs complex (the qrs complex represents ventricular depolarization. The p wave represents the depolarization of the atria. The pr interval represents depolarization of the atria, av node, bundle of his, bundle branches, and the purkinje fibers. The q wave is the first negative deflection following the...

Comprehensive CRNA Interview Review Accurate responses are given. Comprehensive CRNA Interview Review Norepinephrine Mechanism of Action (MOA) A1, A2, B1 agonist. Primary agent used in distributive shock because it's ability to recruit venous volume and augment preload, while increasing arterial tone, and increasing cardiac output. Alpha one causing peripheral smooth muscle contraction. (low dose venous, high dose venous and arterial). Alpha 2 adrenoreceptor agonism actually ant...
