VERIFIED ANSWERS 2025
Malignant vs. benign tumor
Malignant = cancerous, spreads, can come back
Benign = not cancerous, doesnt spread, dont come back
Lipoma
benign adipose tissue tumor
Lymphoma
malignant tumor of lymph tissue
Pheochromocytoma
benign tumor of the adrenal medulla
Epithelial tissue function + examples
= lining, transport, secretion, absorption
- GI tract hollow organs, skin surface
Connective tissue function
= support, strength, elasticity
- bone, tendon, fat
muscular tissue function
= movement
- cardiac, smooth, skeletal
,Nervous tissue function
= information synthesis, communication, control
- brain, spinal cord, nerves
Skeletal muscle is voluntary/involuntary and striated/nonstriated +
how many nuclei
Skeletal tissue is voluntary and striated
- multiple nuclei
Cardiac muscle is voluntary/involuntary and striated/nonstriated
involuntary/striated
smooth muscle is voluntary/involuntary and striated/nonstriated
involuntary/nonstriated
cancer that develops in epithelial cells
carcinoma
Cancer of the connective tissue
Sarcoma
The three types of skin cancer
1. Basal cell carcinoma
2. Squamous cell carcinoma (epidermis)
3. Melanoma (dermis)
Natural barriers of infection
- skin + mucous membranes (throat, nose, urethra, rectum)
- stomach acid
- saliva, mucus
- tears, urine
Autogenous infection
caused by pathogens that pt. already carries
Cross infection
caused by pathogens acquired from another person
Transient microorganisms
transferred from one pt. to another
- soap can clean this
Resident microorganism
, extra risk to immune compromised pt.
- germicidal soap needs to be used
Hepatitis that is transmitted thru fecal contaminated water and food
Hepatitis A + E
Hepatitis that is transmitted thru blood and/or sexual
Hepatitis B,C,D
HAV
- ab discomfort, loss of appetite
(fecal, oral)
HBV
flu like sx., depression, anorexia, fatigue
(blood, fluids)
HCV
joint aches, nausea, anorexia, vomiting, jaundice, dark urine
(blood, fluids)
HDV

(flu like, depression, fatigue)
HEV
Rare in US - fever, malaise, nausea, abrupt
(fecal, oral)
Which hepatitis have a vaccine
A+B
Which hepatitis is chronic
HBV and some of HCV
chronic persistent vs. active Hep. carriers
Persistent = asymptomatic/minimal
Active = progressive sx., malaise, weight loss, jaundice
OSHA regulations
Keeps workplace safe and healthy
