1. A patient with long-standing, untreated hypertension shows an increase in left
ventricular mass on an echocardiogram. This is an example of which cellular adaptation?
A) Hyperplasia
B) Hypertrophy
C) Metaplasia
D) Dysplasia
Answer: B. Hypertrophy is an increase in cell size due to increased mechanical demand,
common in cardiac muscle exposed to high systemic pressure .
2. A tissue biopsy of the cervix reveals abnormal variations in cellular size, shape, and
developmental organization. How should the nurse practitioner document this finding?
A) Hypertrophy
B) Atrophy
C) Dysplasia
D) Metaplasia
Answer: C. Dysplasia refers to deranged cellular growth characterized by atypical size, shape,
and arrangement, often preceding malignancy .
3. A chronic smoker's respiratory tract biopsy shows stratified squamous epithelial cells
replacing normal ciliated columnar cells. This represents:
A) Metaplasia
B) Dysplasia
C) Anaplasia
D) Hyperplasia
Answer: A. Metaplasia is the reversible replacement of one mature cell type by another
better suited to withstand chronic irritation .
4. A patient with nephrotic syndrome develops generalized edema. Which laboratory
abnormality is most likely present?
A) Elevated serum albumin
,B) Proteinuria with hypoalbuminemia
C) Increased serum sodium without protein loss
D) Polycythemia with dehydration
Answer: B. Loss of protein in urine lowers plasma oncotic pressure, causing edema .
5. A patient with rheumatoid arthritis experiences joint destruction due to chronic
inflammation. Which inflammatory mediator plays a significant role in this disease
process?
A) Insulin
B) Dopamine
C) Tumor necrosis factor-alpha
D) Erythropoietin
Answer: C. TNF-alpha promotes synovial inflammation and joint destruction in rheumatoid
arthritis .
6. A patient with hyperparathyroidism is at greatest risk for which complication?
A) Hypocalcemia-induced tetany
B) Kidney stone formation from hypercalcemia
C) Severe hypoglycemia
D) Reduced bone resorption
Answer: B. Elevated parathyroid hormone increases serum calcium, predisposing patients to
nephrolithiasis .
7. A patient develops acute respiratory distress syndrome (ARDS) following severe trauma.
Which hallmark finding is associated with this condition?
A) Increased lung compliance
B) Diffuse alveolar-capillary membrane damage
C) Chronic bronchoconstriction only
D) Pulmonary hypertension without hypoxemia
Answer: B. ARDS causes widespread inflammation and increased permeability leading to
pulmonary edema and hypoxemia .
8. A patient with Addison disease would most likely exhibit which laboratory finding?
A) Hypernatremia and hypokalemia
B) Hyponatremia and hyperkalemia
C) Elevated cortisol levels
D) Increased aldosterone secretion
Answer: B. Adrenal insufficiency causes decreased aldosterone leading to sodium loss and
potassium retention .
, 9. A patient with chronic venous insufficiency develops lower extremity edema and skin
discoloration. Which mechanism contributes most directly to these findings?
A) Increased arterial perfusion
B) Venous valve incompetence causing blood pooling
C) Acute lymphatic obstruction only
D) Reduced capillary permeability
Answer: B. Venous insufficiency leads to elevated venous pressure, edema, and hemosiderin
deposition .
10. A patient with osteoporosis is at increased risk for fractures due to:
A) Excessive bone mineralization
B) Imbalance between bone resorption and formation
C) Increased collagen synthesis
D) Chronic osteoblastic overactivity
Answer: B. Bone resorption exceeds bone formation, reducing bone density and strength .

11. A patient with asthma develops wheezing and dyspnea after allergen exposure. Which
immunoglobulin is primarily involved in this hypersensitivity reaction?
A) IgA
B) IgG
C) IgM
D) IgE
Answer: D. Allergic asthma is mediated by IgE-triggered mast cell activation and
bronchoconstriction .
12. A patient with cirrhosis develops hepatic encephalopathy. Which substance
accumulation contributes most significantly to neurological symptoms?
A) Bilirubin
B) Potassium
C) Ammonia
D) Calcium
Answer: C. Liver dysfunction impairs ammonia detoxification, leading to neurotoxicity .
13. A patient with chronic anemia reports fatigue and dyspnea on exertion. These
symptoms primarily result from:
A) Increased oxygen delivery to tissues
B) Reduced oxygen-carrying capacity of blood
