Section 1: Foundations of Pathophysiology & Pharmacology
1. A client develops severe nausea after starting a newly
prescribed antibiotic. This is best classified as:
A. A genetic disorder
B. A nosocomial infection
C. An iatrogenic condition
D. A congenital anomaly
Correct Answer: C. An iatrogenic condition
Rationale: Iatrogenic conditions are adverse outcomes resulting
from medical treatment, including drug side effects.
2. Which term refers to the cause of a disease?
A. Pathogenesis
B. Etiology
C. Manifestation
D. Prognosis
Correct Answer: B. Etiology
Rationale: Etiology is the study of the cause of a disease.
Pathogenesis (A) refers to disease development.
,3. An increase in the number of cells in a tissue is called:
A. Hypertrophy
B. Hyperplasia
C. Metaplasia
D. Atrophy
Correct Answer: B. Hyperplasia
Rationale: Hyperplasia = increased cell number. Hypertrophy =
increased cell size.
4. A patient develops tissue death due to prolonged lack of
blood supply. This process is called:
A. Apoptosis
B. Necrosis
C. Ischemia
D. Hypoxia
Correct Answer: B. Necrosis
Rationale: Necrosis is irreversible cell death from injury. Ischemia
(C) is reduced blood flow.
5. When prolonged ischemia occurs to an area of the heart,
the resulting damage is referred to as:
A. Atrophy
B. Liquefactive necrosis
,C. Apoptosis
D. Infarction
Correct Answer: D. Infarction
Rationale: An infarct is tissue necrosis caused by prolonged
ischemia from an occluded artery.
6. Which research method ensures that neither participants
nor researchers know who receives treatment?
A. Single-blind study
B. Cohort study
C. Double-blind study
D. Case study
Correct Answer: C. Double-blind study
Rationale: Double-blind reduces bias by masking both
participants and researchers.
7. A short-term illness that develops very quickly is called:
A. Acute
B. Latent
C. Chronic
D. Manifestation
Correct Answer: A. Acute
Rationale: Acute = rapid onset, short duration. Chronic = slow
onset, long duration.
, 8. The term "prognosis" refers to the:
A. Period of recovery
B. Expected outcome of the disease
C. Mortality and morbidity rates
D. Typical collection of signs and symptoms
Correct Answer: B. Expected outcome of the disease
9. A patient with liver failure has difficulty metabolizing
drugs. This affects which pharmacokinetic phase?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Correct Answer: C. Metabolism
Rationale: The liver is the primary site of drug metabolism (Phase I
and II reactions).
10. Which statement about pharmacokinetics is true?
A. Absorption is the process of drug elimination
B. Distribution is movement of drug from blood to tissues
C. Metabolism occurs only in the kidneys
D. Excretion is the breakdown of drugs
