NUR 114 Cellular Regulation Review
Questions and Correct Answers
Explain cell growth by hypertrophy ✅cells get larger
Explain cell growth by hyperplasia ✅number of cells increase
Benign tumor characteristics ✅-remains localized and does not spread to distant sites
-does not usually require intervention
-tissue name + "-oma"
malignant tumor characteristics ✅-mass of abnormal cells resulting from uncontrolled
cancer cell division
-indicates cancer
Primary cancer prevention ✅-Reducing cancer risk in healthy people (education for
prevention).
-reducing the risks of disease through health promotion
-risk reduction strategies: Vaccinations, Immunizations, Activity Lifestyle, Nutrition
Secondary cancer prevention ✅-use of screening strategies to detect cancer early, at
a time when cure or control is more likely
-screening and early detection activities
-identify pre-cancerous lesions and early stage cancer in individuals who lack signs and
symptoms of cancer: Genetic screening in high risk clients
Tertiary cancer prevention ✅-management of disease to prevent progression,
recurrence, or complications includes monitoring tumor markers and detecting second
primary tumors early in those who are long term survivors
-lung CA diagnosed- smoking cessation
-focus on monitoring preventing recurrence of the primary cancer
-Screening for development of secondary malignancies in cancer
-keep from spreading or reoccur/ chemo surgery hormone therapy
General Disease-Related Consequences of Cancer ✅-Reduced immune and blood-
producing function
-Altered GI structure and function- diarrhea, stop eating and drinking, slow peristalsis
-Motor and sensory deficits
-Decreased respiratory function
-immune system- anxious immune system compromised
Cancer ✅Disease process that begins when a cell is transformed by genetic mutation
of cellular DNA
, Metastasis ✅-Abnormal cells invade surrounding tissue and gain access to lymph and
blood vessels carrying them to other areas of the body
-mets- spreading to other areas
-to identify this check lymph nodes, breast cancer check lymph nodes in armpits
-PET scan whole body then biopsy from those cancerous areas metastasis is positive if
its positive in 5/7 lymph areas
Malignant cancer cells ✅cells or processes that are characteristic of cancer
Benign cancer cells ✅cells that are not cancerous
Malignant Process ✅Cell proliferation:
-Genetically altered cells clone and proliferate abnormally
-Evading normal intra/extracellular processes such as growth regulating and immune
system defenses
-Abnormalities in cell signaling processes lead to cancer development
-Ultimately metastasis occurs
Features of Benign Tumor Cells ✅-Continuous or inappropriate cell growth
-Specific morphology
-Small nuclear-to-cytoplasmic ratio
-Specific differentiated functions
-Tight adherence
-No migration
-Orderly growth
-Normal chromosomes
Features of malignant cancer cells ✅-Rapid or continuous cell division
-Anaplasia
-Large nuclear-to-cytoplasmic ratio
-Specific functions lost
-Loose adherence
-Migration
-No contact inhibition
-Rapid or continuous
-Abnormal chromosomes
