Comprehensive Basic Science Self-Assessment
1. A75-year-old man has decreased exercise tolerance and occasional syncopal
episodes related to exertion. Left-heart catheterization discloses this pressure tracing
(Ao -aorta; LV -left ventricle; LA -
left atrium). The most frequently encountered mechanism underlying this disorder is
which of the following?

A) Amyloid deposition

B) Calcification
C) Cystic medial necrosis

Time-
Correct Answer: B.
The pressure tracing demonstrates a large pressure gradient between the left ventricle
and aorta during systole, which is consistent with the diagnosis of aortic stenosis. In the
setting of aortic stenosis, the left ventricle must generate higher pressures in order to
overcome the opening resistance of the stenotic valve. This increased -Correct Answer

C) Macrophages
D) Neutrophils

E) T lymphocytes
Correct Answer: E.
T lymphocytes, which are responsible for the immune attack against the recipient,
should be the target of agents used to treat graft-versus-host disease (GVHD) in HLA-
unrelated bone marrow transplant recipients. Prior to grafting of allogeneic stem cells in
a bone
marrow transplant, recipient native marrow must be completely ablated. It is then
replaced with donor marrow, which recolonizes the marrow cavity. Successful
transplantation results in reconstitution of the immune system with the donor's i -Correct

dihydroxycholecalciferol is undetectable. Serum parathyroid hormone concentration is
above
the upper limit of the laboratory assay and needs to be reassayed at a dilution. The
results are pending. Which of the following is the most likely cause of his condition?
O A) Loss-of-function mutation in the calcium-sensing receptor
B) Multiple endocrine neoplasia type I
C) Mutations inactivating the vitamin D 24-hydroxylase gene
D) Mutations inactivating the vitamin D receptor
Correct Answer: D.

Correct Answer: A.
Positive predictive value (PPV) and negative predictive value (NPV) are statistical
measurements that define the proportion of positive test results that are true positives
(positive tests in patients who have the condition) and true negatives (negative tests in
patients without the condition). PPV is thus defined as (true positives [TP]) / (TP + false
positives [FP]) and measures the probability of a patient having the dise -Correct

F) T lymphocytes
Correct Answer: C.
Hepatocyte injury accounts for this patient's symptoms and coagulation abnormality.
Hepatocytes filter and detoxify portal venous blood, metabolize medications, synthesize
coagulation factors (including fibrinogen, prothrombin, factors V, VII, IX, X, XI, XII,
proteins
C and S), complement, apoproteins, triglycerides, cholesterol, bile acids, and albumin,
and play critical roles in biochemical metabolism (eg, gluconeogenesis). Many manifest

Malignant melanoma is likely to be present when a lesion demonstrates asymmetry,
irregular appearing borders, variable coloration, a diameter greater than 6 mm, and
rapid evolution in characteristics. Malignant melanoma can rapidly invade and
metastasize,
which carries a poor prognosis when diagnosed late. Subtypes include superficial
spreading, nodular, lentigo maligna, and acral lentiginous. Any lesion with features
