NURS 3366 FINAL EXAM 400 ACTUAL QUESTIONS AND
CORRECT VERIFIED ANSWERS WITH RATIONALE
ALREADY GRADED A+ LATEST 2026-2027
This 400-question multiple-choice examination is a comprehensive
preparation resource for the NURS 3366 Final Exam. It covers essential
nursing and pathophysiology topics including cardiovascular disorders (heart
failure, hypertension, coronary artery disease), endocrine disorders (diabetes,
thyroid disease, adrenal disorders), gastrointestinal and hepatic conditions
(cirrhosis, pancreatitis, inflammatory bowel disease), neurological disorders
(stroke, seizures, Parkinson's disease), musculoskeletal and autoimmune
conditions (rheumatoid arthritis, gout, lupus), and renal/urological disorders.
Each question includes a detailed rationale explaining the correct answer and
reinforcing key pathophysiological concepts, clinical manifestations,
diagnostic findings, and evidence-based treatment principles. This resource is
ideal for nursing students preparing for comprehensive final examinations in
medical-surgical nursing and pathophysiology courses.
1. A patient presents to the ER and states that while he was exercising, he felt pain
in his left leg. The pain stopped when he stopped exercising. He also states that his
feet are numb. The nurse notices that his left foot is cold and pale. What is this
patient most likely experiencing?
A) Deep vein thrombosis
B) Chronic venous insufficiency
C) Cerebral aneurysm
D) Peripheral arterial disease
Answer: D
Rationale: Intermittent claudication (pain with exercise that resolves with rest)
combined with cool, pale skin and numbness are classic signs of peripheral arterial
disease (PAD), which is caused by atherosclerotic narrowing of arteries .
2. What is a cause of type 2 diabetes mellitus?
A) No insulin production
B) Obesity
C) Destruction of beta cells
D) Dehydration
Answer: B
,Rationale: Type 2 diabetes mellitus is characterized by insulin resistance, which is
strongly associated with obesity. Unlike type 1 diabetes, it is not caused by an
absolute lack of insulin or autoimmune destruction of beta cells .
3. Type 1 DM is identified as:
A) A total lack of insulin
B) A decrease of insulin production
C) An insulin resistance problem
D) The same as type 2 DM
Answer: A
Rationale: Type 1 diabetes mellitus is an autoimmune disease that results in the
destruction of pancreatic beta cells, leading to an absolute deficiency of insulin.
This requires exogenous insulin therapy for survival .
4. What is the initiating event that leads to the development of atherosclerosis?
A) Release of inflammatory cytokines
B) Macrophages adhere to vessel walls
C) Injury to the endothelial cells that line the artery walls
D) Release of platelet-derived growth factor
Answer: C
Rationale: Endothelial injury is the initiating event in atherosclerosis. This injury
allows lipoproteins to penetrate the vessel wall and triggers an inflammatory
response that leads to plaque formation .
5. What is the effect of oxidized low-density lipoproteins (LDL) in atherosclerosis?
A) They promote vasodilation
B) They are taken up by macrophages to form foam cells
C) They inhibit platelet aggregation
D) They increase HDL levels
Answer: B
Rationale: Oxidized LDL is taken up by macrophages via scavenger receptors,
leading to the formation of foam cells. These foam cells accumulate in the arterial
wall and are a hallmark of early atherosclerotic lesions .
6. Which of the following is the primary mechanism of action of beta-blockers?
A) Increase heart rate
B) Block beta-adrenergic receptors
C) Stimulate alpha-adrenergic receptors
D) Inhibit calcium channels
Answer: B
,Rationale: Beta-blockers reduce heart rate and myocardial contractility by blocking
beta-adrenergic receptors, mainly beta-1 receptors in the heart. This decreases the
workload on the heart and reduces oxygen demand .
7. A patient on warfarin therapy should avoid which of the following foods due to
their vitamin K content?
A) Bananas
B) Leafy green vegetables
C) Apples
D) Rice
Answer: B
Rationale: Leafy green vegetables are high in vitamin K, which can counteract the
anticoagulant effect of warfarin and reduce its efficacy. Consistent vitamin K
intake is important for maintaining stable INR levels .
8. Which lab value should be closely monitored in a patient receiving heparin?
A) Hemoglobin
B) INR
C) aPTT
D) Platelet count
Answer: C
Rationale: Activated Partial Thromboplastin Time (aPTT) is used to monitor
heparin therapy to ensure therapeutic anticoagulation and prevent bleeding
complications. Heparin affects the intrinsic pathway of coagulation .
9. What is the antidote for acetaminophen overdose?
A) Naloxone
B) Atropine
C) N-acetylcysteine
D) Vitamin K
Answer: C
Rationale: N-acetylcysteine replenishes glutathione stores, helping to detoxify the
harmful metabolites of acetaminophen. It is most effective when administered
within 8-10 hours of an acute overdose .
10. A common adverse effect of ACE inhibitors is:
A) Bradycardia
B) Dry cough
C) Hyperglycemia
D) Diarrhea
, Answer: B
Rationale: ACE inhibitors increase bradykinin levels, which can lead to a
persistent, dry cough in some patients. This is a common side effect that often
leads to discontinuation of the medication .
11. Which class of drugs is the first-line treatment for type 2 diabetes mellitus?
A) Sulfonylureas
B) Biguanides
C) Thiazolidinediones
D) Insulin
Answer: B
Rationale: Metformin, a biguanide, is the first-line therapy for type 2 diabetes
because it improves insulin sensitivity and decreases hepatic glucose production
without causing hypoglycemia .
12. What is the therapeutic effect of loop diuretics?
A) Increase sodium and water reabsorption
B) Decrease potassium excretion
C) Increase urine output by inhibiting sodium reabsorption in the loop of Henle
D) Block aldosterone receptors
Answer: C
Rationale: Loop diuretics inhibit sodium-potassium-chloride cotransporters in the
thick ascending limb of the loop of Henle, promoting significant diuresis and
increased urine output .
13. Which of the following drugs is used to treat tuberculosis?
A) Rifampin
B) Ciprofloxacin
C) Metronidazole
D) Acyclovir
Answer: A
Rationale: Rifampin inhibits bacterial RNA synthesis and is a key component of
tuberculosis treatment regimens. It is used in combination with other drugs to
prevent resistance .
14. What is the main side effect to monitor for in patients taking lithium?
A) Hypokalemia
B) Neurotoxicity
C) Hypoglycemia
D) Hypotension
