Pathophysiology NR283 Exam 1 2026/2027 Q&A with Clinical Rationale
1
What is homeostasis?
CORRECT ANSWER: The body's balance. "Normal" values can change based on age, gender, genetics, and
environment.
CLINICAL RATIONALE
1. Homeostasis maintains internal stability despite external changes.
2. Deviation from homeostasis indicates disease or injury.
2
What is a biopsy?
CORRECT ANSWER: Removal of small living tissue to examine.
CLINICAL RATIONALE
1. Biopsy is used for histopathological diagnosis of cancer, inflammation, and other diseases.
3
What is an autopsy?
CORRECT ANSWER: Examination of the body and organs after death.
CLINICAL RATIONALE
1. Autopsy determines cause of death and confirms diagnoses.
4
What is diagnosis?
CORRECT ANSWER: Identifying a disease based on signs, symptoms, and lab tests.
CLINICAL RATIONALE
1. Diagnosis guides treatment decisions and prognosis.
, 5
What is etiology?
CORRECT ANSWER: The cause of a disease.
CLINICAL RATIONALE
1. Etiology may be genetic, infectious, environmental, or idiopathic.
6
What does idiopathic mean?
CORRECT ANSWER: Unknown cause of a disease.
CLINICAL RATIONALE
1. Many autoimmune and neurodegenerative diseases are idiopathic.
7
What are predisposing factors?
CORRECT ANSWER: Factors like age, gender, genetics, and environment that make a person more likely to
get a disease.
CLINICAL RATIONALE
1. Predisposing factors increase susceptibility but do not guarantee disease.
8
What is pathogenesis?
CORRECT ANSWER: The development of a disease.
CLINICAL RATIONALE
1. Pathogenesis explains how disease begins and progresses.
9
What is an acute disease?
CORRECT ANSWER: Develops quickly, severe symptoms.
CLINICAL RATIONALE
1. Examples: appendicitis, pneumonia, influenza.
, 10
What is a chronic disease?
CORRECT ANSWER: Develops slowly, mild symptoms with flare-ups.
CLINICAL RATIONALE
1. Examples: diabetes, hypertension, arthritis.
11
What is a remission?
CORRECT ANSWER: A period when disease symptoms subside.
CLINICAL RATIONALE
1. Common in autoimmune diseases and cancer.
12
What is exacerbation?
CORRECT ANSWER: A worsening of symptoms in a disease.
CLINICAL RATIONALE
1. Also called a flare or relapse.
13
What is a syndrome?
CORRECT ANSWER: A collection of signs and symptoms.
CLINICAL RATIONALE
1. Example: Down syndrome, chronic fatigue syndrome.
14
What is necrosis?
CORRECT ANSWER: Cell death that causes further damage.
CLINICAL RATIONALE
1. Necrosis triggers inflammatory response.
