NSG 3280 Exam 1 - Pathophysiology for Nurses 100
Questions with Correct Answers and Explanations
SECTION 1: INTRODUCTION TO PATHOPHYSIOLOGY
Question 1:
What is the definition of Pathophysiology?
A. The study of the structure of the human body
B. The study of abnormalities in the physiologic functioning of living beings
C. The study of drug interactions within the body
D. The study of psychological responses to illness
Correct Answer: B
Rationale: Pathophysiology refers to the study of abnormalities in the physiologic
functioning of living beings, also known as the study of disease. It seeks to reveal the
physiologic responses of an organism to disruptions in its internal or external
environment.
Question 2:
The nurse is caring for a patient and notes that the cause of the patient's disease is
unknown. How should the nurse document this etiology?
A. Iatrogenic
B. Idiopathic
C. Nosocomial
D. Pathogenic
Correct Answer: B
Rationale: Idiopathic refers to a disease where the cause is unknown. Iatrogenic refers to
causes resulting from unintended or unwanted medical treatment. Nosocomial refers to
hospital-acquired infections. Pathogenic refers to disease-causing microorganisms.
,Question 3:
A patient develops a urinary tract infection following insertion of a urinary catheter. This
is an example of which type of etiology?
A. Idiopathic
B. Congenital
C. Iatrogenic
D. Genetic
Correct Answer: C
Rationale: Iatrogenic conditions result from unintended or unwanted medical treatment.
The catheter insertion was a medical intervention that led to an adverse outcome.
Question 4:
Which term describes the development or evolution of a disease from the initial
stimulus to the ultimate expression of manifestations?
A. Etiology
B. Pathogenesis
C. Epidemiology
D. Prognosis
Correct Answer: B
Rationale: Pathogenesis refers to the development or evolution of a disease from the initial
stimulus to the ultimate expression of manifestations. Etiology is the study of the cause of
disease, epidemiology studies disease patterns in populations, and prognosis is the
predicted outcome.
Question 5:
A patient develops a fever and general malaise, indicating the onset of illness. This is
known as the:
,A. Latent period
B. Subclinical stage
C. Prodromal period
D. Convalescent stage
Correct Answer: C
Rationale: The prodromal period is characterized by the appearance of the first signs and
symptoms indicating the onset of a disease. These early symptoms are often nonspecific
(e.g., malaise, headache, fever).
Question 6:
A patient with hypertension has no symptoms and functions normally, but the disease
process is well established. This is referred to as the:
A. Latent stage
B. Prodromal stage
C. Subclinical stage
D. Acute stage
Correct Answer: C
Rationale: The subclinical stage occurs when the patient functions normally, although the
disease processes are well established. The patient may not be aware of the disease.
Question 7:
A patient with rheumatoid arthritis experiences a sudden increase in joint pain and
swelling. This is known as:
A. Remission
B. Exacerbation
C. Convalescence
D. Sequela
Correct Answer: B
, Rationale: Exacerbation is a relatively sudden increase in the severity of a disease or its
signs and symptoms. Remission is a decrease in severity, convalescence is the recovery
period, and a sequela is a subsequent pathologic condition that results from an illness.
Question 8:
When a disease's signs and symptoms have decreased in severity, the patient is said to
be in:
A. Exacerbation
B. Latent period
C. Remission
D. Prodromal phase
Correct Answer: C
Rationale: Remission refers to an abatement or decline in the severity of the signs and
symptoms of a disease. If remission is permanent (5 years or longer), the person may be
considered cured.
Question 9:
A patient develops scar tissue following a burn injury. This scarring is an example of:
A. Complication
B. Sequela
C. Exacerbation
D. Remission
Correct Answer: B
Rationale: A sequela is a subsequent pathologic condition that results from an illness.
Scarring is a sequela of the burn injury. A complication is an unwanted outcome of a
disease or treatment.
