Symptoms include shortness of breath and jugular vein distention, indicating heart failure.
Symptoms include cough and wheezing, indicating pulmonary issues.
Symptoms include chest pain and palpitations, indicating arrhythmias.
2. What is the characteristic of Stage II heart failure?
No limitation
Severe limitation with symptoms at rest
Moderate limitation with symptoms on less than ordinary activity
Mild limitation with symptoms on exertion

4. What is the primary benefit of pursed-lip breathing for patients with emphysema?
Increases inhalation
Reduces coughing
Improves expiration
Enhances oxygen intake
5. This subtype of macrocytic anemia is due to deficiency or impairment of utilization of Vitamin B12 or
folate
non-megaloblastic
megaloblastic
6. Describe the role of E. coli in urinary tract infections and why it is a common pathogen.
coli is rarely found in urinary tract infections and is not a significant pathogen.
coli is a common pathogen in urinary tract infections due to its ability to adhere to the
urinary tract lining and its prevalence in the gastrointestinal tract.
coli is only found in the bloodstream and does not affect the urinary tract.
coli is primarily responsible for respiratory infections, not urinary tract infections.
7. Which of the following is a cause of vitamin B-12 deficiency?
3/56
, 3/28/25, b4:02 bPM
High levels of vitamin D
Absence of intrinsic factor
Increased intake of vitamin B-12
Excessive absorption of vitamin B-12
8. Describe the relationship between left-sided heart failure and pulmonary edema.
Left-sided heart failure has no impact on fluid levels in the lungs.
Left-sided heart failure leads to increased pressure in the pulmonary circulation, causing
fluid to leak into the lungs.
Left-sided heart failure causes the lungs to produce excess mucus, leading to pulmonary
edema.
Left-sided heart failure decreases blood flow to the lungs, preventing fluid accumulation.
9. What type of hypersensitivity is exemplified by contact dermatitis?
Type 4 hypersensitivity
Type 1 hypersensitivity
Type 3 hypersensitivity
Type 2 hypersensitivity
