Question 1. What physical sign is the result of turbulent blood flow through a
vessel?
Increased blood pressure during periods of stress
Bounding pulse felt on palpation
Cyanosis observed on excretion
Murmur heard on auscultation
Explanation: Where flow is obstructed, the vessel turns or blood flows over rough
surfaces. The flow becomes turbulent with whorls or eddy currents that
produce noise, causing a murmur to be heard on auscultation, such as
occurs during blood pressure measurement with a sphygomanometer. This
selection is the only option that accurately identifies the physical sign of
turbulent vascular blood flow.
Question 2. Which organism is a common sexually transmitted bacterial
infection?
, Staphylococcus aureus
Clostridium perfringens
Helicobacter pylori
Treponema pallidum
Explanation: Treponema pallidum (spirochete, syphilis) is a sexually transmitted disease.
Staphylococcus aureus is commonly ingested, causing food poisoning;
Clostridium perfringens (gas gangrene) is a skin or wound infection;and
Helicobacter pylori (gastritis, peptic ulcers) is found in the gastrointestinal
tract.
Question 3. It has been determined that a tumor is in stage 2. What is the
meaning of this finding?
Cancer is confined to the organ of origin.
Cancer has spread to regional structures.
Cancer is locally invasive.
Cancer has spread to distant sites
, Explanation: Cancer confined to the organ of origin is stage 1; cancer that is locally
invasive is stage 2; cancer that has spread to regional structures, such as
the lymph nodes, is stage 3; and cancer that has spread to distant sites,
such as a liver cancer spreading to the lung or a prostate cancer spreading
to bone, is stage 4.
Question 4. Erythrocyte life span of less than 120 days, ineffective bone
marrow response to erythropoietin, and altered iron metabolism
describe the pathophysiologic characteristics of which type of
anemia?
Aplastic
Sideroblastic
Anemia of chronic disease
Iron deficiency
Explanation: Anemia of chronic disease results from a combination of (1) decreased
erythrocyte life span, (2) suppressed production of erythropoietin, (3)
ineffective bone marrow erythroid progenitor response to erythropoietin,
