,PATHOPHYSIOLOGY CORE MECHANISMS (Q1–Q10)
Q1. A patient with chronic inflammation demonstrates elevated cytokine activity.
Which cellular process is primarily responsible for tissue damage?
A. Cellular hyperplasia
B. Free radical injury and oxidative stress
C. Increased ATP synthesis
D. DNA replication repair
Correct Answer: 🔴 B. Free radical injury and oxidative stress
Explanation: 🔹 Chronic inflammation leads to excess production of reactive oxygen
species causing oxidative damage to lipids, proteins, and DNA. Hyperplasia is adaptive
growth, ATP synthesis is energy production, and DNA repair is protective, not
destructive.

Q2. In shock states, anaerobic metabolism results primarily in accumulation of which
substance?
A. Bilirubin
B. Lactic acid
C. Creatinine
D. Ketone bodies
Correct Answer: 🔴 B. Lactic acid
Explanation: 🔹 Hypoperfusion forces cells into anaerobic glycolysis, producing lactic
acid which contributes to metabolic acidosis. The other options are unrelated
metabolic byproducts.

Q3. Which mechanism best explains edema in heart failure?
A. Increased plasma oncotic pressure
B. Decreased capillary hydrostatic pressure
C. Increased capillary hydrostatic pressure
D. Decreased interstitial fluid volume
Correct Answer: 🔴 C. Increased capillary hydrostatic pressure
Explanation: 🔹 Heart failure causes fluid backup in venous circulation, raising
hydrostatic pressure and pushing fluid into interstitial spaces.

Q4. A patient with autoimmune disease exhibits tissue destruction primarily due to:
A. Bacterial endotoxins
B. Immune-mediated self-antibody attack

,C. Decreased complement activity
D. Hormonal imbalance
Correct Answer: 🔴 B. Immune-mediated self-antibody attack
Explanation: 🔹 Autoimmune disorders involve loss of self-tolerance leading to
antibodies targeting host tissues.

Q5. Hypoxia-induced cellular injury primarily affects which organelle first?
A. Golgi apparatus
B. Mitochondria
C. Lysosomes
D. Ribosomes
Correct Answer: 🔴 B. Mitochondria
Explanation: 🔹 Mitochondria are highly oxygen-dependent; hypoxia disrupts ATP
production leading to cellular failure.

Q6. Which electrolyte imbalance is most associated with neuromuscular excitability?
A. Hypernatremia
B. Hypocalcemia
C. Hypermagnesemia
D. Hyperchloremia
Correct Answer: 🔴 B. Hypocalcemia
Explanation: 🔹 Low calcium increases membrane excitability leading to tetany and
neuromuscular irritability.

Q7. Compensatory tachycardia in hypovolemia occurs due to activation of:
A. Parasympathetic system
B. Renin-angiotensin system only
C. Sympathetic nervous system
D. Hypothalamic suppression
Correct Answer: 🔴 C. Sympathetic nervous system
Explanation: 🔹 Sympathetic activation increases heart rate and vasoconstriction to
maintain perfusion.

Q8. Cellular apoptosis differs from necrosis because apoptosis is:
A. Always inflammatory
B. Uncontrolled cell rupture
C. Programmed cell death without inflammation

, D. Caused by infection only
Correct Answer: 🔴 C. Programmed cell death without inflammation
Explanation: 🔹 Apoptosis is regulated and prevents inflammatory response, unlike
necrosis.

Q9. In sepsis, systemic vasodilation is primarily mediated by:
A. Dopamine depletion
B. Nitric oxide release
C. Increased aldosterone
D. Decreased histamine
Correct Answer: 🔴 B. Nitric oxide release
Explanation: 🔹 Nitric oxide causes vascular smooth muscle relaxation leading to
hypotension.

Q10. Which condition results from decreased surfactant production?
A. Pulmonary fibrosis
B. Atelectasis
C. Pneumothorax
D. Emphysema
Correct Answer: 🔴 B. Atelectasis
Explanation: 🔹 Surfactant deficiency leads to alveolar collapse and reduced lung
expansion.




PHARMACOLOGY PRINCIPLES & SAFETY (Q11–Q20)
Q11. A patient on warfarin presents with elevated INR. The nurse should anticipate
administration of:
A. Vitamin C
B. Vitamin K
C. Heparin
D. Protamine sulfate
Correct Answer: 🔴 B. Vitamin K
Explanation: 🔹 Vitamin K reverses warfarin-induced anticoagulation. Protamine
reverses heparin.
