PATH370 Pathophysiology

Week 1 Quiz  

Question 1          Signs and symptoms of a disease first occur during the

Acute phase

Latent period

Subclinical stage

Prodromal period

Question 2Which term is used to describe the deficiency in circulating platelets?

Anemia

Leukopenia

Leukocytosis

Thrombocytopenia

Question 3Cellular hypoxia results in

Increased pH

Enhanced ATP activity

Loss of intracellular calcium

Failure of the sodium-potassium pump

Question 4Restoration of effective function is the goal of which level of prevention?

Primary

Tertiary

Clinical

Secondary

Question 5 Abnormal new cellular growth is referred to as

Apoptosis

Neoplasia

Proto-oncogene

Suppressor genes

Question 6A critical event in the death of a cell is caused by

Disruption of the plasma membrane s permeability barrier

An increase in cellular protein content

An accumulation of lipofuscin

Chronic nutrient insufficiency

Response Feedback:      Disruption of the plasma membrane barrier, seen in necrosis, results in cellular death. Hypertrophy results primarily from a net increase in cellular protein content Atrophy can result in the accumulation of lipofuscin. Atrophy occurs when cells shrink and reduce their differentiated functions in response to a variety of normal and injurious factors, such as nutrient starvation.

Question 7Which is a true statement regarding metastasis?

Increased cell-to-cell adhesion helps metastasis.

Lack of proteases and collagenases aids in metastasis.

Cells must first escape the basement membrane of tissue.

Penetration of the basement membrane of the vessel occurs first.

Question 8Which statement accurately describes the proliferation of cancer cells?

The resting phase of the cell cycle is prolonged.

Cancer cells grow at the same rate as normal cells.

The number of developing cells exceeds the number of dying cells.

The more anaplastic the tumor is, the slower the growth rate of cells.

Question 9What stage is defined by “fight or flight”?

Alarm

Resistance

Exhaustion

Adaptation

Question 10Which term means cause of the disease ?

Etiology

Risk factor

Pathogenesis

Clinical manifestations

Question 11In what way do proto-oncogenes become activated oncogenes?

A proto-oncogene within the cell stimulates hyperplasia.

Certain retroviruses enter host cells, altering their DNA structure.

Excessive ATP activity causes the proto-oncogene to become abnormally active.

Chromosome replication errors cause fewer copies of the proto-oncogene to be included in the genome.

Question 12An increase in which of these characteristics would be present in cells that demonstrate hypertrophy?

Lipofuscin

Size of vacuoles

Size of cells

Number of cells

Question 13A client develops weakness in both lower extremities following a prolonged period of bed rest. This condition is most likely caused by

Atrophy

Dysplasia

Hypertrophy

Hyperplasia

Question 14Which offers the best prognosis for the cure of cancer?

Surgery

Radiation

Early detection

Chemotherapeutic agents

Question 15Which statement is true regarding cancer? (Select all that apply.)

The greater the undifferentiated cell count, the more aggressive the cancer.

Malignant tumors have the potential to kill the host.

Benign tumors grow rapidly than malignant ones.

Anaplasia means more differentiated cells.

Metastasis means less differentiated cells.

Question 16Which condition explains the genetic basis for cancer development?

Decreased immune function

Exposure to ionizing radiation

Infection by oncogenic bacteria

Loss of or defect in tumor suppressor genes

Question 17Which of these statements best describes the purpose of the TNM classification system?

It tracks the progress of the disease and the effectiveness of treatment.

It provides tumor data for the Centers for Disease Control and Prevention.

It enables the physician to determine the underlying cause of the malignancy.

It provides information for ongoing research efforts to develop a cure for cancer.

Question 18When the cause of a disease is due to unintended or unwanted medical treatment, the term to describe this is

Genotype

Idiopathic

Ecogenetics

Iatrogenic

Question 19Which is true regarding catecholamines?

They are from the parasympathetic nervous system.

They include epinephrine and norepinephrine.

They cross the blood-brain barrier.

They cause a decrease in heart rate.

Question 20The study of specific characteristics and functions of a living organism and its parts is called

Psychiatry

Physiology

Homeostasis

Pathophysiology
