Contact with or handling of blood or body fluids may be hazardous to health

You are called to a residence for a 74-year-old woman who fainted. During your assessment, the patient's son tells you that he was standing next to his mother when she fainted and that he caught her before she fell to the floor. He further tells you that his mother has angina and kidney disease. The patient is now conscious but confused. Her blood pressure is 80/50 mm Hg, pulse is 110 beats/min and weak, and respirations are 22 breaths/min and regular. As your partner administers supplemental oxygen to the patient, you should:

A) assess for the presence of a nitroglycerin patch on the patient and remove it if she is wearing one. B) quickly establish vascular access and administer a 20-mL/kg bolus of an isotonic crystalloid. C) obtain a detailed list of all of the patient's medical problems and the medications that she is taking. D) perform a rapid head-to-toe assessment to determine if she has gross injuries or any hidden conditions.
