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...

.A nurse is assessing a client who is 12hr postoperative following a colon resection. Which of the following findings should the nurse report to the surgeon? 1. Heart rate 90/min 2. Absent bowel sounds → normal findings after major bowel surgery; takes several days to return to normal. 3. Hgb 8.2 g/dl 4. Gastric pH of 3.0 Rationale: Normal Hgb is 13-18M g/dl, 12-16 g/dl. This may indicate a possible hemorrhaging. 2. A nurse is caring for a client who has diabetes insipidus. Whic...

Relative refractory periods - ️️occurs towards the end of the T-wave when most ventricular cells are repolarized and vulnerable to new stimuli; can lead to VT if PVC lands during this time Refractory = resistant Supraventricular Tachycardia (SVT) - ️️§ regular but fast rhythm § rate 150-250 § P wave merged with T wave § PRI variable & difficult to measure § QRSà typically narrow § Common causes: stimulants, electrolyte imbalance, hypoxia Sinoatrial Node (SA node) Rate? ...
