ADVANCED PHYSIOLOGY AND PATHOPHYSIOLOGY: ESSENTIALS FOR CLINICAL
PRACTICE
2nd Edition by Nancy C. Tkacs
CHAPTER 1: THE FOUNDATIONAL CONCEPTS OF CLINICAL PRACTICE (Questions 1–
15)
1. The characteristic, localized cardinal signs of acute inflammation include:
A) Fever
B) Fatigue
C) Redness
D) Granuloma
Answer: C
The cardinal signs of acute inflammation are localized and include redness (rubor), heat
(calor), swelling (tumor), and pain (dolor). Fever and fatigue are systemic
manifestations, not localized cardinal signs .
2. The vascular, hemodynamic stage of acute inflammation is initiated by:
A) Vasoconstriction followed by vasodilation
B) Immediate and sustained vasodilation
C) Persistent vasoconstriction
D) Capillary occlusion
Answer: A
The vascular stage of acute inflammation begins with transient vasoconstriction,
followed by vasodilation of arterioles and venules, which increases blood flow to the
injured area and causes redness and heat .

3. Which of the following mediators of inflammation causes increased capillary
permeability and pain?
A) Histamine
B) Bradykinin
C) Prostaglandins
D) Leukotrienes
Answer: B
Bradykinin is a potent mediator that increases capillary permeability and stimulates
pain receptors. Histamine primarily increases permeability, prostaglandins potentiate
pain, and leukotrienes promote leukocyte adhesion .
4. Which of the following is a systemic manifestation of acute inflammation?
A) Redness
B) Swelling
C) Fever
D) Pain
Answer: C
Fever is a systemic manifestation of inflammation, resulting from the release of
pyrogens that reset the hypothalamic set point. Redness, swelling, and pain are
localized cardinal signs .
5. A postsurgical patient states she is freezing cold. Which measure is the
hypothalamus likely to initiate to reduce heat loss?
A) Opening of arteriovenous shunts
B) Reduced exhalation of warmed air
C) Contraction of pilomotor muscles
D) Decreased urine production
Answer: C
The hypothalamus responds to cold by stimulating piloerection (contraction of
pilomotor muscles) to trap air and reduce heat loss. Arteriovenous shunts close to
conserve heat, not open .

6. An elderly patient dressed in a gown complains of a draft and requests a warm
blanket. Which mechanisms of heat loss are most likely the primary cause?
A) Evaporation and conduction
B) Radiation and convection
C) Conduction and convection
D) Convection and evaporation
Answer: C
Conduction (heat loss through direct contact with cooler surfaces) and convection (heat
loss through air currents) are the primary mechanisms causing the patient's discomfort
from the draft .
7. Which pathophysiologic processes are capable of inducing pyrogen production?
Select all that apply.
A) Acute inflammation
B) Obesity
C) Myocardial infarction
D) Malignancy
E) Renal failure
Answer: A, C, D, E
Pyrogens are produced in response to infection, inflammation, tissue injury (myocardial
infarction), malignancy, and other conditions. Obesity is not a direct pyrogen-inducing
process .
8. Which patient is most susceptible to developing a neurogenic fever?
A) A patient with pneumonia
B) A patient with a traumatic brain injury
C) A patient with a urinary tract infection
D) A patient with rheumatoid arthritis
Answer: B
Neurogenic fever results from damage to the hypothalamus or central nervous system,
which disrupts thermoregulation. Traumatic brain injury is a common cause .
9. The primary mechanism by which a fever is beneficial in fighting infection is:
, Page 4 of 77
A) Direct killing of pathogens
B) Enhanced immune cell function and inhibition of pathogen replication
C) Increased heart rate
D) Reduced metabolic rate
Answer: B
Fever enhances immune function by increasing leukocyte mobility and phagocytosis,
and it inhibits the replication of some pathogens. It does not directly kill pathogens .
10. Which of the following is the correct sequence of events in the inflammatory
response?
A) Vasodilation → increased permeability → leukocyte migration → phagocytosis
B) Leukocyte migration → vasodilation → phagocytosis → increased permeability
C) Increased permeability → phagocytosis → vasodilation → leukocyte migration
D) Phagocytosis → vasodilation → leukocyte migration → increased permeability
Answer: A
Inflammation begins with vasodilation and increased capillary permeability, followed by
leukocyte migration (margination, transmigration, chemotaxis) and phagocytosis .
11. A patient with a wound infection develops swelling at the site. The primary
cause of this swelling is:
A) Increased vascular permeability leading to fluid exudation
B) Vasoconstriction
C) Decreased hydrostatic pressure
D) Lymphatic obstruction
Answer: A
Increased capillary permeability allows plasma proteins and fluid to leak into the
interstitial space, causing edema (swelling) at the site of inflammation .
12. Which cell type is the first to arrive at the site of acute inflammation?
A) Macrophages
B) Neutrophils
C) Lymphocytes
D) Eosinophils
