Study Q&A (2026)
Brian, age 28, began an aerobic exercise program 2 years ago. Brian now competes in long-distance cycling
e e e e e e e e e e e e e e e e e
events and considers himself to be an endurance athlete who is in the "best shape of his life." An
e e e e e e e e e e e e e e e e e e e
echocardiogram reveals a slightly enlarged left ventricle. What cellular change or injury that is best
e e e e e e e e e e e e e e e
exemplified by the case scenario. - correct answerPhysiologic hypertrophy
e e e e e e e e
An ADAPTIVE type of hypertrophy that occurs due to extensive exercise, whereby the heart will create new
e e e e e e e e e e e e e e e e e
blood vessel branches (angiogenesis) and there is increased mitochondria, ATP, and actin/myosin filaments
e e e e e e e e e e e e e
in the muscle.

Recently, Karen learned that not only does HIV directly attack CD4 cells, but the presence of the virus seems to
e e e e e e e e e e e e e e e e e e e e
activate pathways responsible for programmed cell death in CD4 cells. Thus, HIV infection appears to increase
e e e e e e e e e e e e e e e
the rate of "suicide" for CD4 cells. - correct answerApoptosis
e e e e e e e e e e
,Define dysplasia - correct answerCompared to normal cells, cells demonstrating dysplasia are atypical in size
e e e e e e e e e e e e e e e
and shape. Dysplasia does not mean the cells are cancerous. However, some screening tests, such as the Pap
e e e e e e e e e e e e e e e e e e
smear, examine tissues to determine if any cellular changes are taking place. Any changes in the cells can then
e e e e e e e e e e e e e e e e e e e
be monitored over time.

A biopsy of a skin lesion is conducted on Leann, a 48-year-old woman. Biopsy results revealed proliferating
e e e e e e e e e e e e e e e e e
cells that were well-differentiated and resembled surrounding cells. The cells were contained within a well-
e e e e e e e e e e e e e e
defined area. - correct answerBenign neoplasia. e e e e e
Neoplasia is uncontrolled and unregulated cell growth. The mass of tissue resulting is known as a "neoplasm."
e e e e e e e e e e e e e e e e e
In a benign neoplasm, the cells do not have the characteristics associated with malignancy. The cells, although
e e e e e e e e e e e e e e e e e
cancerous, are well-differentiated, meaning they resemble normal, mature cells. The cells are also in a e e e e e e e e e e e e e e e
contained area and are unlikely to spread. e e e e e e
Miguel, a retired warehouse supervisor, had a myocardial infarction. Further evaluation revealed he had
e e e e e e e e e e e e e e
significant blockage in his left descending coronary artery. The blockage resulted in ischemia and cell death
e e e e e e e e e e e e e e e e
for those cells served by the artery. - correct answerNecrosis
e e e e e e e e e
Necrosis is premature cell death caused by cell injury. Necrosis differs from apoptosis, in that the cellular
e e e e e e e e e e e e e e e e e
destruction results from some form of trauma, rather than genetic programming. May lead to GANGRENE e e e e e e e e e e e e e e e
which is when dead tissue houses bacteria.

Julianne, who suffers from familial hypercholesterolemia, presents with xanthomas. Xanthomas are excess
e e e e e e e e e e e e
cholesterol deposits, which appear as yellow skin lesions. What cell process is this - correct e e e e e e e e e e e e e e e
answerIntracellular accumulation. e
Some disease processes stimulate intracellular accumulations of particles, such as calcium, cholesterol, and
e e e e e e e e e e e e e
triglycerides, glucose, among other substances. In familial hypercholesterolemia, a genetic defect causes e e e e e e e e e e e e
decreased cellular uptake of cholesterol, resulting in high serum cholesterol levels. Cholesterol deposits,
e e e e e e e e e e e e e
known as xanthomas, may appear to form under the skin.

Janae experienced a frightening ATV accident, in which her ATV flipped over and she ended up catching a
e e e e e e e e e e e e e e e e e e
portion of her upper arm on a barbed wire fence. Although Janae's injuries healed fully, enlarged, keloid scar
e e e e e e e e e e e e e e e e e e
formations remain at the injury site. - correct answerHyperplasia e e e e e e e e
, cell proliferation, known as hyperplasia, was stimulated as a result of her injury. A keloid results from
e e e e e e e e e e e e e e e e e
overgrowth of granulation tissue during the wound repair process. e e e e e e e e
Hypertension that leads to workload on the left ventricle and thus enlargement would be deemed? - correct
e e e e e e e e e e e e e e e e e
answerPathological hypertrophy. e e
No blood vessel growth and increased workload would lead to ischemia and enlargement of the heart.
e e e e e e e e e e e e e e e e
NCLEX TIP: Left ventricular hypertrophy would lead to displacement of the PMI during chest palpation.
e e e e e e e e e e e e e e
Hyperplasia occurs from which two mechanisms? - correct answerAn INCREASE in the number of cells in a
e e e e e e e e e e e e e e e e e
tissue or organ. e e
1) hormonal (estrogen stimulating the mitotic division of breast gland cells; also BPH in older males)
e e e e e e e e e e e e e e e
2) overcompensation during regeneration (keloid scars)

Andy has undergone a colonoscopy because his family has a history of colon cancer. Biopsy of the colon
e e e e e e e e e e e e e e e e e e
reveals poorly differentiated cells in the samples. Cells were abnormally organized, with distorted borders.
e e e e e e e e e e e e e e
Infiltration of the abnormal cells occurred throughout several samples. - correct answerMalignant neoplasia
e e e e e e e e e e e e
Neoplasia is uncontrolled, unregulated cell growth. Malignancy, when applied to neoplasm, indicates the
e e e e e e e e e e e e e
cancerous cells are likely to infiltrate other tissues and spread. The appearance of malignant cells is far from
e e e e e e e e e e e e e e e e e e
normal. Such cells are poorly differentiated and appear to have a random organization. Biopsy samples of
e e e e e e e e e e e e e e e e
malignant neoplasia reveal cells moving beyond the borders or edges of the growth.

Walter, age 62, had to undergo an endoscopic examination of his esophagus due to his complaint of frequent
e e e e e e e e e e e e e e e e e e
"heartburn" after most meals. Examination of the cells shows that rather than normal squamous cells lining
e e e e e e e e e e e e e e e e
the esophagus, Walter had columnar cells - correct answerMetaplasia

Cardiac catheterization results for Beatrice, a 54-year-old patient, show plaque build-up, appearing as
e e e e e e e e e e e e e
hardened areas in the coronary arteries. Beatrice, who is overweight and leads a sedentary lifestyle, has
