Questions & Verified Answers
1. Which process results in the replacement of one mature cell type by another, often as a response to
chronic irritation?
A. Atrophy
B. Hyperplasia
C. Dysplasia
D. Metaplasia
Answer: D
Rationale: Metaplasia is a reversible replacement of one mature cell type by another adult cell type, typically seen in the
respiratory tract of smokers.
2. A 50-year-old male with chronic renal failure presents with a potassium level of 6.8 mEq/L. Which ECG
change is most characteristic of this condition?
A. Prominent U waves
B. Shortened PR interval
C. Tall, peaked T waves
D. ST segment elevation
Answer: C
Rationale: Hyperkalemia (potassium > 5.0 mEq/L) typically causes tall, peaked T waves and widening of the QRS complex.
3. Which type of hypersensitivity reaction is mediated by IgE and involves the release of histamine from
mast cells?
A. Type IV
B. Type II
C. Type III
D. Type I
Answer: D
Rationale: Type I hypersensitivity is IgE-mediated and includes allergic reactions like anaphylaxis and seasonal allergies.
4. In the Renin-Angiotensin-Aldosterone System (RAAS), what is the primary function of Angiotensin II?
A. Stimulation of sodium excretion
B. Potent vasoconstriction
C. Decreasing blood pressure
D. Inhibiting ADH secretion
Answer: B
Rationale: Angiotensin II is a potent vasoconstrictor and stimulates the secretion of aldosterone, both of which increase
blood pressure.
5. A patient has a deficiency in antidiuretic hormone (ADH). Which clinical manifestation should the
nurse expect?
A. Oliguria
B. High urine specific gravity
C. Polyuria
D. Low serum sodium
Answer: C
Rationale: ADH deficiency leads to Diabetes Insipidus, characterized by the excretion of large volumes of dilute urine
(polyuria).
