Shock can best be described as:
A) hypotension.
B) a decrease in myocardial contractility.
C) decreased cardiac output.
D) a state of inadequate tissue perfusion.
Question 2
Your patient is a 72-year-old male who is conscious but lethargic and sitting in a chair. His son states that the patient has been a bit slow lately and has been gaining weight. The medical history includes hypothyroidism and myocardial infarction. The patient has been compliant with his Synthroid and has nitroglycerin for use as needed.

HR = 60 and regular, BP = 112/80, RR = 10 and shallow, SaO2 = 92, temperature = 88F,blood glucose = 180 mg/dL. Your treatment of this patient should include:
