Questions & Verified Answers
1. A patient is diagnosed with Barrett’s esophagus, where normal squamous epithelium is
replaced by columnar epithelium. This is an example of which cellular adaptation?
A. Hyperplasia
B. Dysplasia
C. Metaplasia
D. Atrophy
Answer: C
Rationale: Metaplasia is the reversible replacement of one mature cell type by another, often as a
response to chronic irritation. Clear understanding of this concept improves both test performance and
everyday clinical judgment. Practice applying it to short case scenarios to lock the idea in place. This
knowledge supports safe care and helps the nurse teach the client and family clearly and simply. Clear
teaching improves cooperation and reduces anxiety.
2. Which process involves the programmed cell death that does not typically trigger an
inflammatory response?
A. Necrosis
B. Autolysis
C. Saponification
D. Apoptosis
Answer: D
Rationale: Apoptosis is a regulated ‘cell suicide’ mechanism that tidily disposes of cells without
leaking cytoplasmic contents into the extracellular space. Understanding this helps the nurse notice
early warning signs and act before the problem gets worse. Early action often prevents bigger
complications for the client. Remembering this point will help you decide the best nursing action when
similar questions appear on the exam. Link the answer to the client’s current condition and risk level.

3. A patient presents with severe edema. Which physiological change most likely contributes
to this condition?
A. Increased capillary oncotic pressure
B. Decreased capillary hydrostatic pressure
C. Increased interstitial hydrostatic pressure
D. Decreased capillary oncotic pressure
Answer: D
Rationale: Decreased capillary oncotic pressure (often due to low albumin) reduces the ‘pull’ of fluid
back into the vessels, leading to interstitial accumulation. This knowledge supports safe care and helps
the nurse teach the client and family clearly and simply. Clear teaching improves cooperation and
reduces anxiety. Exam questions often test whether you can pick the most practical and safe choice
for the client in real situations. Focus on what the nurse can actually do right now.
4. Which electrolyte imbalance is most likely to cause peaked T waves on an EKG?
A. Hyperkalemia
B. Hypercalcemia
C. Hypokalemia
D. Hyponatremia
Answer: A
Rationale: Hyperkalemia alters the cardiac action potential, characteristically resulting in narrowed,
peaked T waves. Remembering this point will help you decide the best nursing action when similar
questions appear on the exam. Link the answer to the client’s current condition and risk level. Exam
questions often test whether you can pick the most practical and safe choice for the client in real
situations. Focus on what the nurse can actually do right now.
