Question 16
10 / 10 pts
Explain what necrosis is and give an example and description of one type of necrosis.
Your Answer:
necrosis is when cell dies in an organ/tissues that is still alive .this process can interferes with the
tissue regeneration and how cell can be replace.
one type of necrosis is gengrenouse necrosis which can bowel or the lower extremities that may
causes changes in tussue and it functions
Necrosis refers to cell death in an organ or tissues that is still part of a living person. It
often interferes with cell replacement and tissue regeneration. Coagulative necrosis results
most often from a sudden cutoff of blood supply to an organ (ischemia), particularly the
heart and kidney. Liquefactive necrosis occurs when some of the cells die but their catalytic
enzymes are not destroyed. It is commonly seen with brain infarcts or abscesses. Caseous
necrosis occurs as part of granulomatous inflammation and is most often associated with
tuberculosis.
Gangrenous necrosis most often affects the lower extremities or bowel and is secondary to
vascular occlusion. The term gangrene is applied when a considerable mass of tissue
undergoes necrosis. In dry gangrene the affected tissue becomes dry and shrinks, the skin
wrinkles, and its color changes to dark brown or black. The spread of dry gangrene is slow.
It results from a cut off in arterial blood supply and is a form of coagulation necrosis. In
wet gangrene, the affected area is cold, swollen, and pulseless. The skin is moist, black, and
under tension. Blebs form on the surface, liquefaction occurs, and a foul odor is caused by
bacterial action. The spread of tissue damage is rapid.

Question 18
5 / 10 pts
List the 4 types of tissue found in the body. Pick 2 and give a description and example of each.
Your Answer:
nervours tissue-can be find throughout the body and it's used for communication.
muscle tissue
connective tissue
epithelial-(covers the outer surface of the body and lines the inner surfaces.
Epithelial tissue covers the body’s outer surface, lines the inner surfaces, and forms
glandular tissue. Epithelial tissue has three distinct surfaces and the basal surface is
attached to an underlying basement membrane. It is avascular, meaning without blood
vessels. It receives oxygen and nutrients from the capillaries of the connective tissue on
which it rests.
Connective or supportive tissue is the most abundant tissue in the body. It connects and
binds or supports the various tissues. Its cells produce the extracellular matrix that support
and hold tissues together. Connective tissue is divided into two types: connective tissue
proper and specialized connective tissue (cartilage, bone, and blood cells). The four types of
connective tissue proper are loose (areolar), adipose, reticular, and dense connective tissue.
The function of muscle tissue is to move the skeletal structures, pump blood through the
heart, and contract the blood vessels and visceral organs. Muscle tissue can accomplish this
by contraction. The two types of fibers that contract are called thin and thick filaments.
Thin filaments are called actin, and the thick filaments are myosin. The three types of
muscles tissue are skeletal, cardiac, and smooth.
Nervous tissue is distributed throughout the body for communication. It provides the
means for controlling body function and for sensing and moving about the environment.
b. Radiation injury
c. Chemical injury
d. Biologic agents
The two types of cells are neuron and glial cells. Neurons function is communication. Glial
(meaning glue) cells support the neurons.

Question 5
10 / 10 pts
1. What are the three possible goals of cancer treatment?
2. How does radiation kill cancer cells?
Your Answer:
1) the three goal is to curative,control and palliative
2) radiation kill cancer cells by using high energy/waves particles to destroy/damage cancer
cells.However this treatment can sometimes interrupt the cells cycle by killing good cells or
damaging DNA cells
1. Curative, control, palliative
2. Radiation therapy uses high-energy particles or waves to destroy or damage cancer cells.
This leads to the creation of free radicals, which damage cell structures. Radiation can
interrupt the cell cycle process, kill cells, or damage DNA in the cells.

Question 13
10 / 10 pts
A 40-year-old woman has experienced heavy menstrual bleeding. She was told she has a uterine
tumor called a leiomyoma. She is worried she has cancer. What do you tell her? Explain at least 2
differences between a benign and malignant tumor.
Your Answer:
I will tell her not to worry because leiomyoma is a non-cancerous tumor and it can be surgically
remove and to always have a regular doctor visit
two differences between a benign and malignant tumor is that has a well-differentiated cells and
have slow progressive growth rate.Malignant tumor is more aggressive because it destroy
tissue,grows rapidly and spread to other body parts and lacks well defined margins
Leiomyoma is a benign tumor. (Leiomyosarcoma is malignant) Student can add any of the
following: Benign tumors are well-differentiated cells, resemble the cells of tissues of origin,
and have a slow, progressive rate of growth. They grow by expansion and remain localized
to their site of origin, not capable of metastasizing. They develop a rim of connective tissue
around the tumor called a fibrous capsule, which aids in surgical removal. Benign tumors
are less of a threat unless they interfere with vital functions
Malignant neoplasms invade and destroy tissue. They grow rapidly, spread to other parts of
the body, and lack well-defined margins. They can compress blood vessels and outgrow
their blood supply, causing ischemia and tissue injury. Surgery can be more difficult if it
has spread.
Question 14

3) hw benefited from low dose chest CT that could be done yearly
(1) Metastasis- a cancer cell must break loose from the primary tumor, invade the
surrounding extracellular matrix, gain access to a blood vessel, survive its passage in the
bloodstream, emerge at a favorable location, invade the surrounding tissue, begin to grow,
and establish a blood supply. (2) Chest pain, shortness of breath, cough, bone pain. (3)
Yearly low-dose chest CT.

Question 18
10 / 10 pts
List three characteristics of cancer cells and briefly explain what it means:
Your Answer:
cancer cells grow in an altered cell differentiation and growth which can also be called neoplasia
they can have a neoplasm growth where normal tissue lacks regulatory controls
cancer cells also have genetic abnormalities that causes uncontrollble proliferation and can cause
normal call or benign tumors into malignant tumors
Answer: Any of the following
Anaplasia is the loss of cell differentiation in cancerous tissue.
Genetic instability means they have a high frequency of mutations.
Growth factor independence means cancer cells can proliferate even in the absence of growth
factors.
Cell density-dependent inhibition means cancer cell don’t stop growing when they come into
contact with each other.
Cell cohesiveness and adhesion means they don’t stick together.
Anchorage dependence means cancer cells aren’t anchored to neighboring cells or the
underlying matrix to live and grow.
Cell-to-cell communication in cancer cells is poor, which interferes with intercellular
connections and responsiveness to membrane-derived signals.
Life span is unlimited – cancer cells are immortal.
Antigen expression -cancer cells contain several cell surface molecules or antigens that are
immunologically identified as foreign.
Cancer cells can produce enzymes, hormones, and other substances that the tissues of origin
either does not produce or produces in much smaller amounts.
Cancer cells can show cytoskeletal changes or abnormalities. This includes abnormal
intermediate filament types or changes in actin filaments and microtubules that help with
invasion and metastasis.

Exam 3
Question 1
5 / 5 pts
Short answer
Explain the challenges of diagnosing autoimmune disorders.
Your Answer:
since there are too many autoimmune disorder,diagnosing is made by serological finding,history
or physical testing.blood testing could have been a good way to test but since some blood are
more generic can be elevated to show other diseases therefore it best go by finding that are listed.
There are over 80 identified, many with overlapping presentations. Many manifestations
are nonspecific and are seen in other non-autoimmune diseases. Blood testing isn’t perfect
either, as some tests are more generic and can be elevated in the presence of other diseases.

symptoms?
Your Answer:
it can be a cause od Type I hypersensitivety/ IGE as well as allergy, which is responisible for
her symptoms and treatment such as penicillin or some allergy medications
(1) Mast cells, basophils, and eosinophils play an important role in the development of type
I reactions because they contain the chemical mediator histamine. A primary or initialphase response is vasodilation, vascular leakage, and smooth muscle contraction. A
secondary or late-phase response is characterized by more intense infiltration of tissues
with eosinophils and other acute and chronic inflammatory cells, as well as tissue damage.

Question 19
5 / 10 pts
1, A 32-year-old woman presents to the clinic for her initial obstetrics visit, about 10 weeks into
her pregnancy. She is in a monogamous relationship. (1) Should an HIV test be part of her initial
blood work? Why?
2. An infant is born, and its initial antibody test is positive for HIV. (2) Does this mean the
infant is infected? What would be the more appropriate test to detect HIV in this infant?
Your Answer:
Although she's in a monogamous relationship and have one partner it is still a good idea to test
for HIV in her initial blood work because if tested positive,it can be transmet directly to the baby
through birth or in the mother milk while breastfeeding.
2) yes,the baby has been infected most likely the virus has been transmission from it's
mother,and the most appropriate test to detect HIV in this infants will be to use the DNA/RNA
polymerase cain reaction (PCR) becaue the infants would still have ther mother's antibodies
1. Yes. Transmission from mother to infant is the most common way that children become
infected. The CDC recommends all people between ages 13 and 64 be routinely screened for
HIV. Earlier detection and treatment lead to better outcomes.
2. No. The polymerase chain reaction (PCR) test is a nucleic acid test that can detect HIV
DNA. It tests for the presence of the virus, rather than the antibody, which is helpful in
diagnosing HIV infection in infants born to infected mothers. These infants would have
their mother’s antibodies whether or not they have been infected.

2. What happens during exercise in someone with coronary artery disease?
Your Answer:
1 by increasing the cardica output or physical myocardial changes
2 they might have streangth the heart muscle and improve over all hearth or lower chances of
heart attack
1. An increase in wall stress can be caused by an increase in preload or afterload.
Ventricular hypertrophy is an adaptive mechanism by which the ventricle can offset the
increase in wall stress. OR Blood pressure elevation increases the workload of the left
ventricle by increasing the pressure against which the heart must pump as it ejects blood
into the systemic circulation. Over time, the left ventricle hypertrophies to compensate for
the increased pressure and work.
2. During exertion, the heart beats harder and faster to supply oxygen to the muscles. The
coronary vessels vasodilate and increase blood flow to the cardiac muscle to meet its
increased demand for oxygen. With atherosclerotic disease, the coronary vessel lumens are
narrowed and blood supply to the heart is diminished. With exertion, the vessels cannot
adequately vasodilate. This can manifest as chest pain or tightness and/or shortness of
breath.

Question 15
10 / 10 pts
Short answer:
A 10-year-old boy who is having an acute asthma attack is brought to the ER. He is observed to
be sitting up and struggling to breathe. His breathing is accompanied by use of accessory
muscles, a weak cough, and audible wheezing sounds. His pulse is rapid and weak, and both
heart and breath sounds are distant on auscultation. His parents relate that his asthma began to
worsen after he developed a “cold,” and now he doesn’t get relief from his albuterol inhaler.
Explain the changes in physiologic function underlying his signs and symptoms.
Your Answer:
In most asthma patients there's a airway inflammation from cold virus that causes epithelial
injury.Also due to severe airway imflammation this patient is most likely experiencing bronchial
hyper-responisiveness which causes airway obstruction or narrowing. However, this changes can
cause fixed obstruction in asthma patients which is not reversible event with the used of inhalers
or bronchodilaters
Recruitment of inflammatory cells from the bloodstream into the bronchial wall, where
they directly attack the invading organisms and secrete inflammatory chemicals that are
toxic to the organisms causes airway inflammation. Swelling of the bronchial wall, mucus
secretion, constriction of the airway; bronchial hyper-responsiveness to stimuli causes
airway obstruction or narrowing. They may discuss on a cellular level as well:
Upon a trigger, the cascade of neutrophils, eosinophils, lymphocytes, and mast cells cause
epithelial injury. This causes airway inflammation, which further increases
hyperresponsiveness and decreased airflow. Mast cells release histamine and leukotrienes.
These cause major bronchoconstriction, inflammation, and mucus secretion. Mast cells can
trigger multiple cytokine release, which causes more airway inflammation. The contraction
of the airways and subsequent swelling leads to further airway obstruction.
Question 16
10 / 10 pts
Short answer:
When is the risk for obstructive atelectasis the greatest? What are strategies to decrease the
chance for developing atelectasis?
Your Answer:
the risk is greatest following surgery because anesthesia pain medication and immobility may
help to develope bronchial secretions.
strategies such as frequently coughing,taking deep breath,hydrate adepuately and changes
positions may decrease the chance for atelectasis
The risk of obstructive atelectasis is increased following surgery. Anesthesia, pain and pain
medications, and immobility promote retention of bronchial secretions. Patients are
encouraged to frequently cough, deep breath, change positions, hydrate adequately, and
ambulate early to prevent atelectasis.
Question 17
10 / 10 pts
Short answer:
Explain why the oxygen flow rate for people with COPD is normally titrated to maintain the
arterial PO2 between 60 and 65 mm Hg.
Your Answer:
Because their medullary respiratory center is now fuction at a elevated Co2 level and can't not
responds to increase in PCO2.when there is a decrease in PO2 it become a stimulus for
but if there is a higher rate of oxygen,it would suppresses respiratory drive and respiration
stimulus
levels and no longer 2 Their medullary respiratory center has adapted to the elevated CO
becomes the stimulus for 2 . Therefore, a decrease in PO 2 responds to increases in PCO
respiration. If oxygen is given at too high of a rate, it suppresses the stimulus and the
respiratory drive.

and blurred vision. She then lost consciousness, and he immediately called 911. She has a
history of hypertension, and she is not compliant with her medication because she does not like
the way it makes her feel. Based upon these symptoms and past medical history, what do you
suspect this patient is experiencing? How would you confirm this diagnosis? What treatment
should be administered? Explain why you chose that treatment.
Your Answer:
this patient could be experiencing ishemic stroke, and ACT scan or MRI can be done to
determine if there is clot that may be blocking blood flow to the brain. if ischemic stroke is
confirm, the patient would need a more advance treatment methods because they have passed the
3-4.5 hours window for a tPA drugs
Answer: This patient is more than likely experiencing a hemorrhagic stroke given the
sudden onset of her symptoms and the PMH of uncontrolled hypertension. A CT scan
would be needed to determine if a hemorrhage has occurred. Once this is determined the
goal of treatment is to stop bleeding and decrease intracranial pressure. This can be done
through medication that would decrease blood pressure and intracranial pressure. A
craniotomy can be done should medication not work, or the bleeding is severe. Other
surgical methods may be utilized if the bleed is a result of an aneurysm or AVM.

Question 20
5 / 5 pts
Short Answer:
Explain why renal flow is decreased with sympathetic activity.
Your Answer:
because sympathetic activity deverts blood to the heart,skeletal nuscle and brain which is control
by the nervous system.therefore when there is a narrowing in the afferent arteriole,there will be a
release of epinephrine which will most likely lead decrease of flow in the renal and GFR
Answer: Sympathetic activity diverts blood to the heart, brain, and skeletal muscles.
During these times the renal autoregulatory system may be superseded by nervous system
control. In this event, a narrowing of the afferent arteriole is caused by sympathetic nerve
fibers followed by a release of epinephrine from the adrenal medulla which leads to a
subsequent decrease in renal flow and the GFR.

If someone loses their balance when walking on uneven terrain, explain how tendons and
ligaments work to protect the joint and structures within it.
Your Answer:
the tedons and ligament works by promoteing movment of the body and connect bones and
nuscles.when there is increase strech or torsional strain,there will be an reflexive response cause
by nerve fibers which causes tension on the muscles protecting joints and capsule which has the
tension
The tendons and ligaments of joints serve in proprioception (the awareness of ones’
position in space or movement of the body). When these structures undergo stretch or
torsional strain, these proprioceptive nerve fibers will cause a reflexive response to adjust
the tension on the muscles (to maintain balance and not fall over) that support the joint
protecting the capsule and other joint structures.

through the central haversion and volkmann canals.
Cancellous bone does not have a direct blood supply,and receive its blood supply from diffusion
through the endosteal bone surface extending outward through the canaliculi
Cortical bone has a direct blood supply. Nutrient and Perforating arteries form an
anastomosis (collateral circulation) that circulates through the bone through the Haversian
and Volkmann canals. Cancellous bone does not have a direct blood supply. It receives its
blood supply through diffusion from the endosteal bone surface extending outward through
the canaliculi.
Question 22
5 / 5 pts
A 22-year-old competitive gymnast has experienced amenorrhea for the past 5 years. Her PCP is
suspecting that she may have premature osteoporosis. Would you expect her OPG levels to be
high, normal, or low? Explain why her levels would be at this level.
Your Answer:
She has a high RANKL levels,because of Estrogen whhich increase the production of OPG that
has RANKL.However,lower estrogen levels would lead to lower OPG levels which will increase
RANKL and osteoclast activity
Her OPG levels would be low. Amenorrhea results in lower estrogen levels. Estrogen
increases the production of OPG in turn decreasing osteoclast activity. If estrogen levels
are low, OPG levels would also be low resulting in increased osteoclast activity.
Question 23
10 / 10 pts
A 68-year-old, white Caucasian female has a DEXA scan at the recommendation of her PCP.
Her scan yielded a T-score of -2.6. Interpret the results of her DEXA scan. Develop a treatment

and/or class of drug), and a non-pharmacologic recommendation.
Your Answer:
The T-score shows a normal bone density but due to patients background such as age,race and
gender a calcium supplement or vitamin D and activities such as walking and exercise would be
recommend.
This T-score indicates osteoporosis. This patient should take a Calcium and Vitamin D
supplement. In addition, she should be prescribed one of the following: Estrogen, SERMs,
Bisphosphonates, or Calcitonin. She should also participate in regular weight bearing and
resistive exercise being careful to choose activities that would not put her at increased risk
for falling.

Better treatment plan is to maintain normal uric acid leaves,as well as exercise as lower alcohol
intake.
diet changes-avoid food that are rich in purine such as bacon,shellfish and fish can help prevent
futrue attacks.
Phase 3 of gout is called inter-critical gout. The patient is asymptomatic, and no joint
abnormalities are present. The goal of treatment in this phase is to maintain normal uric
acid levels and prevent progression of the disease. Allopurinol is a prescription drug that is
used to reduce uric acid levels. This patient should be encouraged to lose weight and
decrease his alcohol consumption. He should also avoid purine rich foods such as fish,
bacon, and liver. (*Note – the student has to provide 1 pharmacologic intervention and 1
non-pharmacologic recommendation.)
