NSG5003 EXAM 300 ACTUAL QUESTIONS AND
CORRECT ANSWERS WITH RATIONALE
LATEST UPDATE ALREADY GRADED A+
This comprehensive question bank contains 300 completely unique, multiple-
choice questions specifically designed for the NSG5003 Advanced
Pathophysiology exam at South University and similar graduate nursing
programs. Every question is distinct, covering the entire course curriculum
including cellular pathophysiology, immunology, genetics, and
pathophysiology of all major organ systems across the lifespan. Topics include
cardiovascular, pulmonary, renal, endocrine, neurological, musculoskeletal,
gastrointestinal, reproductive, and hematologic disorders, as well as fluid and
electrolyte imbalances and acid-base disturbances. Each question includes
four answer options, a single correct answer, and a detailed rationale
1. What two types of hearing loss are associated with noise?
A) Acoustic trauma and noise induced
B) High frequency and low frequency
C) High frequency and acoustic trauma
D) Noise induced and low frequency
Answer: A
Rationale: Two types of hearing loss are associated with noise: (1) acoustic
trauma or instantaneous damage caused by a single sharply rising wave of sound
(e.g., gunfire), and (2) noise-induced hearing loss, the more common type, which is
the result of prolonged exposure to high-intensity sound .
2. A hypersensitivity reaction that produces an allergic response is called:
A) Hemolytic shock
B) Anaphylaxis
C) Necrotizing vasculitis
D) Systemic erythematosus
Answer: B
Rationale: Anaphylaxis is a severe, life-threatening hypersensitivity reaction that
produces an allergic response. Hemolytic shock, necrotizing vasculitis, and
systemic erythematosus are related to other immune mechanisms .
,3. In the digestive system, which gastric secretion is responsible for converting
pepsinogen to pepsin and acts as a bactericide against swallowed organisms?
A) Gastroferrin
B) Hydrochloric acid
C) Intrinsic factor
D) Chymotrypsin
Answer: B
Rationale: Hydrochloric acid (HCl) is secreted by parietal cells in the stomach.
Its low pH denatures proteins, converts inactive pepsinogen to active pepsin, and
kills most swallowed bacteria. Gastroferrin binds iron, intrinsic factor is for B12
absorption, and chymotrypsin is a pancreatic enzyme .
4. Of the two movements that promote intestinal motility, which occurs more
frequently?
A) Segmentation
B) Peristalsis
C) Vagal stimulation
D) Neural reflex
Answer: A
Rationale: Segmentation involves rhythmic, non-propulsive contractions of
circular muscle that mix chyme and increase contact with absorptive mucosa. It
occurs much more frequently than peristalsis, which moves contents forward less
often .
5. In Wilson disease, where does copper accumulation cause damage that leads to
movement disorders?
A) Cerebellum
B) Basal ganglia
C) Corpus callosum
D) Insular cortex
Answer: B
Rationale: Copper accumulation in Wilson disease preferentially damages the
basal ganglia, a structure deep in the cerebrum that coordinates movement. This
leads to the classic triad of dysarthria, dystonia, and tremor .
6. What is the primary function of amylase found in saliva?
A) Begin protein digestion
B) Begin carbohydrate (starch) digestion
C) Emulsify fats
D) Neutralize gastric acid
, Answer: B
Rationale: Salivary amylase initiates the chemical breakdown of complex
carbohydrates (starches) into smaller polysaccharides and disaccharides in the
mouth and esophagus before being inactivated by gastric acid .
7. Which immunoglobulin is found in high concentration in saliva and provides a
first line of defense against inhaled and ingested pathogens?
A) IgE
B) IgA
C) IgG
D) IgM
Answer: B
Rationale: Secretory immunoglobulin A (sIgA) is the predominant antibody in
mucosal secretions including saliva, tears, and respiratory/gastrointestinal mucus.
It binds pathogens and prevents their attachment to epithelial surfaces .
8. Which organ is most commonly the site of metastasis from malignant tumors
originating in the intestine?
A) Lungs
B) Brain
C) Liver
D) Bones
Answer: C
Rationale: Venous blood from the intestines drains into the portal vein, which
carries it directly to the liver. Thus, the liver is the first filter and the most common
site for hematogenous metastasis of colorectal and other intestinal cancers .
9. What is the initial, non-surgical treatment for an infant diagnosed with
intussusception?
A) Nasogastric decompression
B) Intravenous fluids and observation
C) Air or barium enema
D) Bowel resection
Answer: C
Rationale: In pediatric intussusception, a contrast enema is both diagnostic and
therapeutic. The pressure can reduce the telescoped segment, avoiding emergency
surgery in most cases .
10. A patient with a history of chronic alcohol use presents with ataxia, nystagmus,
and confusion. This classic triad is most consistent with which condition?
, A) Delirium tremens
B) Korsakoff syndrome
C) Wernicke encephalopathy
D) Hepatic encephalopathy
Answer: C
Rationale: Wernicke encephalopathy is a neurologic emergency caused by
thiamine deficiency, most commonly in chronic alcoholics. The classic triad of
symptoms is encephalopathy (confusion), oculomotor dysfunction (nystagmus),
and ataxia.
11. What is the most common cause of dementia in older adults?
A) Vascular dementia
B) Lewy body dementia
C) Alzheimer disease
D) Frontotemporal dementia
Answer: C
Rationale: Alzheimer disease is the most common cause of dementia, accounting
for 60-80% of cases. It is characterized by progressive memory loss and cognitive
decline due to amyloid plaques and neurofibrillary tangles.
12. A patient presents with a "butterfly rash" across the cheeks and bridge of the
nose. This finding is most consistent with which autoimmune disorder?
A) Rheumatoid arthritis
B) Systemic lupus erythematosus
C) Sjögren syndrome
D) Scleroderma
Answer: B
Rationale: A malar rash in a butterfly distribution is a classic sign of systemic
lupus erythematosus (SLE). It is an autoimmune disorder that can affect multiple
organ systems.
13. Which type of immunity is present at birth and provides immediate, non-
specific defense against pathogens?
A) Adaptive immunity
B) Passive immunity
C) Innate immunity
D) Active immunity
Answer: C
