1.) A 50-year-old man with a 20-year history of type
2 diabetes mellitus has had sensory neuropathy for 2 weeks.
Pulses are decreased at the ankle. There is no peripheral edema. His serum
glucose levels have been between 150 mg/dL and 200 mg/dL over the past 6
months. Which of the following is the most effective measure to prevent
serious foot infections?
A) Use of support hose
B) Use of well-fitted shoes
C) Prophylactic antibiotics
D) Daily aspirin and dipyridamole
E) Decrease in serum glucose level
9. A 57-year-old man has been hospitalized for 2
days for treatment
of unstable angina pectoris. He is currently
receiving intravenous
heparin and undergoing evaluation for coronary artery
bypass grafting.
His blood pressure is 160/90 mm Hg, pulse is 88/min,
and respirations are
16/min. Laboratory studies show:
Platelet count 90,000/mm3
Prothrombin time 12 sec (INR=1.1)
Partial thromboplastin time 35 sec
Which of the following is the most likely cause of
these findings?
A
) Excessive platelet destruction
B
) Factor VIII deficiency
C
) Inadequate platelet production
D
) Uncontrolled activation of coagulation and
fibrinolytic cascades
E
) Vitamin K deficiency
