QUESTION: 4 days after an Ivor-Lewis esophagectomy, you decide to start enteral tube feeding
through a J-tube. The long chain fatty acids contained in the tube feeds:
a. Enter the circulation via the portal system
b. Enter the circulation via lymphatics
c. Are only synthesized in the body
d. Are not found in chylomicrons - ANSWER-(b)
Long-chain FAs enter the body through terminal lacteals (absorption through the lymphatic
system) either as free LCFAs or as chylomicrons
Medium- and short-chain FAs along with proteins/CHO enter through the portal circulation
QUESTION: Cells divide during what phase of the cell cycle?
a. G1
b. S
c. G2
d. M - ANSWER-(d)
Cells divide during the M phase (most radiosensitive)
QUESTION: Cell cycle length is determined by what phase of the cell cycle?
a. G1
,2|Page
b. S
c. G2
d. M - ANSWER-(a)
G1 ↔ G0 phase determines cell cycle length (most variable cell period)
Most RNA/protein synthesis
QUESTION: Of the following, which is the most critical component in the neovascularization of
tumor metastases?
a. HER receptor
b. VEGF receptor
c. Neu receptor
d. FGF receptor - ANSWER-(d)
Vascular endothelial growth factor (VEGF) receptor
2 weeks after a whipple operation, your patient continues to have early satiety with oral intake.
You decide to start metoglopramide (Reglan) and erythromycin. What receptor does
erythromycin bind to increase gastrointestinal motility? - ANSWER-Motilin (found primarily in
the stomach, duodenum, and colon)
QUESTION: Proteins are synthesized from:
a. mRNA
b. tRNA
c. dsDNA
d. ssDNA - ANSWER-mRNA

QUESTION: 1 week after an APR, our patient develops urosepsis requiring volume resuscitation,
antibiotics, and moderate amounts of levophed and vasopressin. E. coli grows out from the
blood cultures. What portion of the lipopolysaccharide complex accounts for its toxicity -
ANSWER-Lipid A (with gram negative sepsis; stimulator of TNFα)
QUESTION: Steroid hormones:
a. Bind a receptor on the plasma membrane and activate a plasma membrane enzyme
b. Bind a cytoplasmic receptor, enter the nucleus, and affect transcription of proteins
c. Bind a receptor in the nucleus and affect transcription of proteins
d. Do not enter the cell - ANSWER-(b)
Bind a receptor in the cell cytoplasm, enter the nucleus as a steroid-receptor complex, and
affect transcription of proteins
QUESTION: For its anticoagulation effects, heparin binds:
a. Protein C
b. Protein S
c. Anti-thrombin III
d. Factor VII - ANSWER-(c)
ATIII (heparin-ATIII complex binds thrombin, factor IX, factor X, and factor XI)
QUESTION: 7 days after a kidney transplant, your patient develops severe acute rejection with
vasculitis on biopsy. You decide to start the monoclonal antibody OKT3. Monoclonal antibodies:
, 4|Page
a. Bind 1 epitope at one site
b. Bind 1 epitope at multiple sites
c. Bind multiple epitopes on a single antigen
d. Bind multiple epitopes on multiple antigens - ANSWER-(a)
They bind one epitope at the exact same binding site
QUESTION: You start coumadin on a patient with a pulmonary embolus. Three days later, he
starts sloughing off skin across his arms and legs. All of the following are true of this patients
most likely condition except:
a. This likely would have been prevented by starting heparin before coumadin
b. Patients with protein C deficiency are more susceptible to this problem
c. The skin sloughing is caused by skin necrosis
d. This is likely due to hemophilia A - ANSWER-(d)
Coumadin-induced skin necrosis occurs in patients started on coumadin without being given
heparin first. It results from a relatively hypercoagulable state that can occur in some
individuals because of the shorter half-life of protein C & S compared to factors II, VII, IX, and X.
Protein C & S ↓ after coumadin before the other factors ↓, resulting in a relatively
hypercoagulable state.
QUESTION: While performing a LAR for colon cancer in a patient on chronic dialysis, you notice
a significant amount of bloody oozing from your dissection plane. All of the following are true of
uremic induced platelet dysfunction except:
a. Down regulates GpIb
b. Down regulates GpIIb/IIIa
c. Stimulates von Willebrand's factor release
d. Treatment of choice is dialysis - ANSWER-(c)
