NRSG 357: Cancer Care Exam Questions
and Answers Graded A+
What is interphase? - Correct answer-Period where the cell spends most of its time,
primarily have cell growth occur, but no cell division, this is where most cells live,
expect cancer
What is G1 phase? - Correct answer-the first part of interphase, longest phase of
the cell cycle, where we produce extra organelles such as ribosomes and proteins
What is G0 phase? - Correct answer-no more cell division-cells go here sometimes
instead of S
What is S phase? - Correct answer-synthesis phase, DNA synthesis-this is where
the DNA replicates
What is G2 phase? - Correct answer-another growth phase where we are more
directly preparing for mitosis
What is mitosis? - Correct answer-active cell division
What are cyclin-dependent kinases (CDK)? - Correct answer--Protein kinases that
regulate the cell cycle (mitosis; kinases add a phosphate group);

,-works together with cyclins;
-always present in a cell, but their default function is to be inactive
How are CDK activated? - Correct answer--Cyclin proteins
-specific cyclins made at specific times
What happens when the tumor suppressor loses its function? - Correct answer--
Tumors are able to grow because the cell cycle is not controlled
-Cancer. Tumors have a defect in p53. P21 does not lead to cancer when it is
defected.
What is hyperplasia? - Correct answer-Increase in the amount of organic tissue that
results from cell proliferation
What is hypertrophy? - Correct answer-The increase in the volume of an organ or
tissue due to the enlargement of its component cells
What is dysplasia? - Correct answer-Presence of cells of an abnormal type within a
tissue which can signify cancer
What is metaplasia? - Correct answer-The reversible transformation of one
differentiated cell type to another
What is apoptosis? - Correct answer-The normal occurrence of cellular death

, What is contact inhibition? - Correct answer-Regulatory mechanism that functions
to keep cells growing into a layer one cell thick
What is angiogenesis? - Correct answer-The development of new blood vessels
What is protoonocgene? - Correct answer-Normal cell genes that regulate the
normal cell processes
What is onocgene? - Correct answer-Tumor inducing genes
What is tumor suppressor gene? - Correct answer-regulate cell growth
What is neoplasm? - Correct answer-A new growth of abnormal tissue that is
uncontrolled and progressive
What is a neoplastic? - Correct answer-cancer
What is cancer? - Correct answer--A group of diseases characterized by
uncontrolled and unregulated cell growth
-is an umbrella term
-ALL are genetic (a mutation on the cells DNA); is genetic but not always
hereditary
Who does cancer affect? - Correct answer-affects all ages, ethnic groups, both
genders
