Physical examination reveals swelling to the face, hands, and feet; cool and moist skin; and lung sounds that are clear and equal bilaterally. HR = 104, BP = 142/88, RR = 14, SaO2 = 96%. In addition to administering oxygen and monitoring the cardiac rhythm, which of the following courses of action is most appropriate?

Which of the following symptoms is not a typical symptom of asthma?

On inspection of a patient's ECG strip, you note no identifiable P waves; rapid irregular undulations of the isoelectric line; and an irregular ventricular rhythm. In addition, the precordial cardiac rate is greater than the peripheral pulse rate. The most likely problem is:

A. 2nd degree (Wenckebach) heart block B. ventricular fibrillation C. atrial fibrillation D. ventricular tachycardia

Once access to the patient is obtained, if a potential spine injury is suspected, what should you immediately do?
