,Unit 1: Cellular, Fluid, & Acid-Base Basics (Questions 1–15)
1. A patient with long-standing, untreated hypertension shows enlargement of the left
ventricle on an echocardiogram. This is an example of which cellular adaptation?
o A) Hyperplasia
o B) Hypertrophy
o C) Metaplasia
o D) Dysplasia
o Rationale: Hypertrophy is an increase in individual cell size due to increased
mechanical workload, common in cardiac muscle which cannot undergo
mitosis.
2. A tissue biopsy of a chronic smoker's bronchi reveals that normal ciliated columnar
epithelium has been replaced by stratified squamous epithelium. Which term describes
this?
o A) Anaplasia
o B) Hyperplasia
o C) Metaplasia
o D) Dysplasia
o Rationale: Metaplasia is the reversible replacement of one mature cell type by
another, less differentiated mature cell type to better withstand chronic
irritation.
3. A Pap smear result returns showing abnormal changes in cervical cell size, shape, and
organization. The nurse knows this is termed:
o A) Atrophy
o B) Hypertrophy
o C) Metaplasia
o D) Dysplasia
o Rationale: Dysplasia refers to abnormal, chaotic cellular growth with variations
in size, shape, and arrangement. It is often a precursor to cancer.
4. What is the primary cellular consequence of ischemia that directly leads to cell swelling?
, o A) Decreased ATP production causing failure of the sodium-potassium pump
o B) Increased intracellular pH breaking down lysosomal membranes
o C) Rapid influx of potassium ions into the intracellular space
o D) Total cessation of anaerobic glycolysis
o Rationale: Ischemia cuts off oxygen, halting oxidative phosphorylation. The
resulting lack of ATP shuts down the Na⁺/K⁺ ATPase pump, leading to
intracellular sodium accumulation and osmotic swelling.
5. During hypoxic cell injury, a dangerous influx of which intracellular ion activates
destructive enzymes like proteases and phospholipases?
o A) Sodium
o B) Potassium
o C) Calcium
o D) Magnesium
o Rationale: Ischemia causes calcium to flood into the cytoplasm from
extracellular spaces and the endoplasmic reticulum, activating enzymes that
destroy cellular structures.
6. Which type of necrosis is characteristically seen in brain tissue death following an
ischemic stroke?
o A) Coagulative necrosis
o B) Liquefactive necrosis
o C) Caseous necrosis
o D) Fat necrosis
o Rationale: Brain tissue is rich in digestive hydrolytic enzymes and lipids, causing
dead tissue to dissolve rapidly into a soft, liquid mass.
7. A patient presents with severe peripheral edema secondary to liver failure and low
serum albumin levels. Which capillary force alteration caused this fluid shift?
o A) Increased capillary hydrostatic pressure
o B) Decreased capillary oncotic pressure
, o C) Increased interstitial oncotic pressure
o D) Decreased interstitial hydrostatic pressure
o Rationale: Albumin provides the primary pulling force keeping water inside
blood vessels. Low albumin reduces capillary oncotic pressure, letting fluid leak
into tissues.
8. A patient is admitted with a serum sodium level of 118 mEq/L. Which clinical
manifestation is the highest priority for the nurse to monitor?
o A) Severe thirst and dry mucous membranes
o B) Confusion, lethargy, and seizures
o C) Hyperreflexia and muscle twitching
o D) Orthostatic hypotension and tachycardia
o Rationale: Severe hyponatremia (<120 mEq/L) causes fluid shifts into brain
cells, leading to cerebral edema, which manifests as neurological emergencies.
9. An ECG reveals tall, peaked T waves in a patient with acute kidney injury. Which
electrolyte imbalance should the nurse suspect?
o A) Hypokalemia
o B) Hyperkalemia
o C) Hypocalcemia
o D) Hypercalcemia
o Rationale: Hyperkalemia alters myocardial cell membrane potentials,
classically presenting with narrow, tall, peaked T waves.
10. A patient presents with muscle spasms, positive Chvostek's, and positive Trousseau's
signs. Which lab value aligns with these findings?
o A) Serum Calcium 10.5 mg/dL
o B) Serum Calcium 6.8 mg/dL
o C) Serum Potassium 5.5 mEq/L
o D) Serum Potassium 3.2 mEq/L
