Medical Flashcards
Proper management of a dental implant patient about to undergo chemotherapy includes all of the following considerations, EXCEPT:
a. routine use of antibiotics
b. a prechemotherapy dental evaluation by a dentist with expertise in oncology
c. recognition by the dentist of any evidence of implant failures
d. consideration for removal of ailing root forms, blade and subperiosteal implants
that has entered the antrum, which create a risk of fistulization
e. if surgical removal of implants is planned, the oncologist must know the number
of postoperative days to be allowed for oral healing before chemotherapy can
safely begin
a. routine use of antibiotics
All of the following statements correctly describe infection in the immunosuppressed
chemotherapy patient, EXCEPT:
a. infection is the most common complication in immunosuppressed chemotherapy patients
b. leucopenia is any situation in which the total number of circulating granulocytes or polymorphonuclear leukocytes is less than normal
c. normal granulocyte level is 3500-4000 cells per cu mm in a healthy individual
d. neutrophilic polymorphonuclear leukocytes are the most numerous of all cell types
found in the acute phase of the inflammatory reaction
e. many chemotherapeutic agents interfere with the action and number of neutrophils
and thereby inhibit phagocytosis
c. normal granulocyte level is 3500-4000 cells per cu mm in a healthy individual
On average, a healthy adult has between 4,000 and 11,000 white cells per cubic millimeter or microliter of blood. A high WBC count often means that an infection is present in the body, while a low number can mean that a specific disease or drug has impaired the bone marrow’s ability to produce new cells.

Which of the following monitors the anticoagulant action of heparin?
a. complete blood count
b. activated partial thromboplastin time
c. prothrombin time
d. bleeding time
e. antiplatelet clotting time
b. activated partial thromboplastin time
Hyperthyroidism is accompanied by which of the following?
a. osteoporosis
b. a decrease of calcium and phosphorus in the urine
