BCEN STUDY GUIDE PART ONE, Questions and answers, 100% Accurate. Verified. A patient comes in with chest pain, diaphoresis, denies dyspnea. VSS, breath sounds clear and equal, EKG shows inferior wall ST segment elevation. You anticipate the following oxygen order: A. No supplemental oxygen B. Nasal cannula at 6 L per minute C. Partial rebreather mask at 10 L per minute D. Nonrebreather mask at 15 L per minute - -A. No supplemental oxygen at this time as it is not indicated in normoxia. Giving supplemental oxygen in the setting of normoxia does not improve outcome and has been shown to extend the size of an MI. A patient complains of chest pain, dyspnea, and diaphoresis. Which of the following assessment factors would indicate a possible diagnosis of acute coronary syndrome? A. Pleuritic chest pain B. Positional chest pain C. Chest pain that radiates to the shoulders, with pain in the right shoulder worse than pain in the left shoulder D. Pain reproducible with chest wall palpation - -C) Chest pain that radiates to both shoulders has a likelihood ratio of 7.1 of ACS and pain that radiates to the right shoulder has a stronger likelihood ratio of 2.9 of predicting ACS compared with pain that radiates only to the left shoulder. WRONG ANSWER RATIONALES: A) Pleuritic chest pain has a likelihood of ACS of 0.2 B) Positional chest pain has a likelihood of ACS of 0.3 D) Reproducible chest pain has a likelihood of ACS of 0.3 Which of the following human compensatory mechanisms to the presence of shock triggers glycogenolysis?
