CCRN QUESTIONS with correct answers

The nurse is caring for a patient with acute inferior wall MI, post-coronary artery stent deployment, For optimal care of the patient, the nurse should: answer Continuously monitor the patient in lead II It is best practice to monitor the patient status post PCI with stent, in the lead that was most abnormal during the acute occlusion. The ECG demonstrates ST elevation in leads II, III and aVF. The nurse needs to monitor the patient closely for which of the following? answer Complication likely to occur after an acute inferior wall MI include bradycardia secondary to ischemia to the SA and/or AV node, and papillary muscle rupture or dysfunction due to the anatomical distance between the RCA and the papillary muscle. Which of the following hemodynamic profiles would benefit from the aggressive fluid administration, pressers and antibiotics therapy? a. RAP: 1mm Hg; PAOP: 4 mmHg; SVR: 1800 dynes/sec; CO: 2L/min b. RAP: 5; PAOP: 7; SVR: 400; CO; 8L answer B. the hemodynamic profile of RAP 5, PAOP 7, SVR 400 is typical of septic shock, and choice B would be the best approach. Which of the following is indicative of a mixed acid-base disorder? A. pH 7.18; PaCO2 25; PaO2 64; HCO3 11 B. pH 7.33; PaCO2 29; PaO2 72; HCO3 15 answer The decrease in PaCO2 is evidence of respiratory alkalosis and the decreased HCO3 is evidenced of a metabolic acidosis. The pt with severe sepsis or septic shock may present with this mixed acid
