Chemical mediators released during the inflammatory response include:

Albumin and fibrinogen

Growth factors and cell enzymes

Macrophages and neutrophils

Histamine and prostaglandins

Edema associated with inflammation results directly from:

Increased fluid and protein in the interstitial compartment

Increased phagocytes in the affected area

Decreased capillary permeability

Genreal vasoconstriction

The warmth and redness related to the inflammatory response results from:

Increased interstital fluid

Production of complement

A large number of white blood cells (WBCs) entering the area

Increased blood flow into the area

The process of phagocytosis involves the:

Ingestion of foreign material and cell debris by leukocytes

Shift of fluid and protein out of capillaries

Formation of a fibrin mesh around the infected area

Movement of erythrocytes through the capillary wall

Systemic effects of severe inflammation include:

Erythema and warmth

Loss of movement at the affected joint

Fatigue, anorexia, and mild fever

Abscess formation

The term leukocytosis means:

Increased white blood cells (WBCs) in the blood

Decreased WBCs in the blood

Increased number of immature circulating leukocytes

Significant change in the proportions of WBCs

Which of the following statements applies to fever?

Viral infection is usually present

Heat-loss mechanims have been stimulated

It is caused by a signal to the thalamus

It results from release of pyrogens into circulation

Replacement of damaged tissue by similar functional cells is termed:

Fibrosis

Regeneration

Resolution

Repair by scar tissue

Scar tissue consists primarily of:

Granulation tissue

Epithelial cells

Collagen fibers

New capillaries and smooth muscle fibers

Which of the following promotes rapid healing?

Closely approximated edges of wound

Presence of foreign material

Exposure to radiation

Vasoconstriction in the involved area

WHich of the following drugs relieves fever and some types of pain but is NOT an anti-inflammatory agent?

Acetaminophen

Prednisone

Aspirin

Ibuprofen

A burn area in which the epidermis and part of the dermis is destroyed is classified as:

Full-thickness

Deep partial-thickness

Superficial partial-thickness

First-degree

A women has burns on the anterior surfaces of her right arm, chest, and right leg. The percentage of body surface area burned is approximately:

13.5%

18%

22.5%

31.5%

The characteristic appearance of a full-thickness burn is:

Painful with multiple blisters

Heavy bleeding

Red with some swelling

Dry, firm, charred, or hard white surface

A typical soucre of infection in burns areas is:

The skin grafts

Microbes surviving in the hair follicles in the burn area

Circulating blood bringing microbes to the burn wound

Opportunistic virus in digestive tract

A large burn area predisposes to decreased blood pressure because:

Bleeding occurs under the burn surface

The heart is damaged by toxic materials from the burn

Fluid and protein shift out of the blood

Vasoconstriction occurs in the burn area

During an inflammatory response, hyperemia is caused by:

Increased blood flow in the area

Increased cappillary permeability

Irritation of sensory nerve ending by histamine

Increased leukocytes in the area

A serous exudate is best described as a:

Thin, watery, colorless exudate

Thick, sticky, cloudy secretion

Thick, greenish material containing microboes

Brownish, clotted material

Systemic manifestations of an inflammatory response include:

Edema and erythema

Area of necrosis and loss of function

Pain and tenderness

Fever and malaise

Some local effects of a general inflammatory response would include:

High, spiking fever and chills

Redness,warmth, and swelling

Leukopenia and reduced erythrocyte sedimentation rate (ESR)

Anorexia and headaches

Application of ice to an injured knee reduces edema by:

Promoting return of lymph fluid

Causing local vasoconstriction

Increasing the rate of tissue repair

Causing systemic vasodilation

Healing of large areas of skin loss (including dermis and epidermis) would be most successful through:

Rapid mitosis and regeneration of skin layers

Resolution of damaged cells in the area

Covering the area with biosynthetic skin substitute

Graft of fibrous tissue to the area

The number of neutrophils in the blood is increased significantly:

During allergic reactions

During chornic inflammation

To produce antibodies

In order to promote phagocytosis

Nonspecific agents that protect uninfected cells against viruses are called:

Neutrophils

Macrophages

Interferons

Pyrogens

28. Which chemical mediator is involved in prolonging the inflammatory response?

Bradykinin

Histamine

Leukotrienes

Chemotactic factors

Aspirin (ASA) is discouraged for treatment of viral infection in children because of:

Decreased bone growth after puberty

Frequent production of blood clots

Formation of a granuloma filled with virus

The risk of developing Reye's syndrome

Potential complications after healing by scar formation include all the following EXCEPT:

Lack of sensory function in the area

Contractures and adhesions

Increased hair growth

Keloid formation

31. Why is an application of cold recommended as part of the RICE first aid measures immediately following an inflammatory response due to injury?

It improves circulation in the area removing chemical mediators

It causes local vasoconstriction to reduce local edema

It draws more phagocytic cells to the area to remove debris.

It promotes immediate healing.

Which of the following helps to localize and “wall off” the foreign material during an inflammatory response?

Lymphocytes

Increased fluid

Fibrinogen

Antibodies

One goal for current research in tissue engineering is to:

Create a functional replacement tissue when regeneration is not possible

Adapt cells from the injured organ to produce replacement tissue

Design a nonliving synthetic replacement tissue.

Use stem cells as a temporary covering for damaged tissue.

Identify the correct statement about burns:

The severity of the burn depends on the temperature, duration, and extent of the burn

Young children are less likely to suffer severe burns from immersion in excessively hot water.

Burns to the palms of the hands are more damaging than burns on the face.

With a major burn, excessive bleeding usually causes shock.

Which statement applies to the recommended emergency care for burns?

Drop and lie completely still on your back.

Call a neighbor for help if the burn appears to be extensive.

Apply lotion and cover burn tightly with a sheet or towel.

Cover the burn area with clean, cool, or tepid water and remove nonsticking clothing

Inhalation of carbon monoxide is a threat for many burn patients because this gas:

Causes swelling in the trachea.

Quickly reduces the available oxygen in the blood

Prevents full expansion of the lungs.

Is toxic to the nervous system.
