MCQ (Clinical Case) please help with answer/source - ammoryyy
#1
A 55-year-old nonsmoking business executive is referred to you for evaluation
of a 3-cm solitary pulmonary nodule in the right lower lobe. The lesion was
found on a CXR obtained during a routine physical examination. The patient
is asymptomatic, has no history of abnormal bleeding during or after previous
dental procedures or shaving, and takes 325 mg of enteric-coated aspirin each
day. Physical examination is normal. There are no old CXR to obtain for
comparison; a chest CT scan shows the nodule to be noncalcified and located
in the lateral basilar segment of the right lower lobe. No other CT
abnormalities are found. Because of travel plans that cannot be changed, the
patient requests that any diagnostic procedure you recommend be done within
3 days. Which of the following should be done prior to performing fiberoptic
bronchoscopy with transbronchial biopsies?
A. Order prothrombin time, partial thromboplastin time, platelet count, and bleeding time.
B. Order bleeding time.
C. Infuse 0.3 μglkg ofdearnino-8-D-arginine vasopressin (DDAVP) 15 minutes before the
procedure.
D. Continue aspirin and perform the procedure.
E. Transfuse 4 units of platelets 30 minutes before performing the procedure
