1. **Question: What is the pathophysiology of type 1
diabetes mellitus?**
**Answer:** Type 1 diabetes mellitus (T1DM) is an
autoimmune disorder where the body’s immune system
mistakenly attacks and destroys the beta cells in the
pancreas that produce insulin. This leads to an absolute
deficiency of insulin, resulting in elevated blood glucose
levels. Without insulin, glucose cannot enter cells and is
instead released into the bloodstream, leading to
hyperglycemia. Over time, chronic hyperglycemia can
cause damage to various organs and systems, leading to
complications such as nephropathy, retinopathy, and
neuropathy.
,### 2. **Question: How does chronic obstructive
pulmonary disease (COPD) affect the respiratory
system?**
**Answer:** COPD is characterized by persistent
inflammation and obstruction of the airways, primarily due
to chronic bronchitis or emphysema. In chronic bronchitis,
there is excessive mucus production and chronic cough
due to inflammation of the bronchial tubes. In emphysema,
the alveoli (air sacs) are damaged and lose elasticity,
impairing gas exchange. Both conditions lead to airflow
limitation, increased resistance to airflow, and difficulty in
breathing, which can result in respiratory distress and
reduced oxygenation.
### 3. **Question: Describe the pathophysiology of
congestive heart failure (CHF).**
**Answer:** Congestive heart failure occurs when the
heart is unable to pump blood effectively to meet the
body’s needs. This can result from various conditions,
such as coronary artery disease, hypertension, or
cardiomyopathy. In CHF, the heart’s decreased pumping
ability leads to fluid accumulation in the lungs (pulmonary
congestion) and other tissues (peripheral edema). The
reduced cardiac output triggers compensatory
mechanisms, including the activation of the
,renin-angiotensin-aldosterone system (RAAS) and
sympathetic nervous system, which can exacerbate fluid
retention and worsen the condition over time.
### 4. **Question: What are the key features of
rheumatoid arthritis and its impact on the joints?**
**Answer:** Rheumatoid arthritis (RA) is an autoimmune
disease characterized by inflammation of the synovial
joints. The synovial membrane becomes inflamed, leading
to swelling, pain, and stiffness in the affected joints. This
chronic inflammation can result in joint damage, erosion of
cartilage, and deformities such as ulnar deviation. Over
time, the disease can lead to functional impairment and
reduced quality of life due to pain and decreased joint
mobility.
### 5. **Question: Explain the pathophysiology of acute
renal failure.**
**Answer:** Acute renal failure (ARF), also known as
acute kidney injury (AKI), is a sudden decline in renal
function characterized by a rapid increase in serum
creatinine and/or a decrease in urine output. It can be
caused by prerenal, intrinsic renal, or postrenal factors.
Prerenal causes include reduced blood flow to the
kidneys, such as in hypovolemia or shock. Intrinsic renal
, causes involve damage to the renal parenchyma, such as
in acute glomerulonephritis or acute tubular necrosis.
Postrenal causes are related to obstruction of urine flow,
such as in kidney stones or prostate enlargement. ARF
leads to the accumulation of waste products and fluid
imbalance, affecting multiple organ systems.
### 6. **Question: What is the underlying mechanism of a
myocardial infarction?**
**Answer:** A myocardial infarction (MI), commonly known
as a heart attack, occurs when there is a sudden blockage
of blood flow to a part of the heart muscle, usually due to a
thrombus (blood clot) in a coronary artery. This blockage
deprives the heart muscle of oxygen and nutrients, leading
to ischemia and necrosis of the affected myocardial tissue.
The extent of damage depends on the size of the blocked
artery and the duration of the ischemia. The myocardial
infarction can result in compromised heart function,
arrhythmias, and potentially heart failure.
### 7. **Question: How does hypertension contribute to
the development of stroke?**
**Answer:** Hypertension, or high blood pressure, is a
major risk factor for stroke. Chronic high blood pressure
can lead to damage and weakening of the blood vessel
