LUNG DISEASES 2026 QUESTIONS WITH
SOLUTIONS GRADED A+
⩥ What does fluid in the pulmonary tissue result in. Answer: the areas
are flooded and results in pulmonary edema and dyspnea
⩥ cor pulmonale. Answer: right-sided heart failure
⩥ right sided heart failure. Answer: inability of the right ventricle to
provide adequate blood flow into the pulmonary circulation
⩥ Causes of right sided heart failure. Answer: - pulmonary disease
- pulmonary hypertension
- RV MI
- RV Hypertrophy
- pulmonary SLV or tricuspid valve damage
- secondary to left heart failure
⩥ What is the most common cause of right sided heart failure. Answer:
pulmonary hypertension
,⩥ Progression of right sided heart failure. Answer: - damage causes the
right ventricle to increase contraction force to eject/unload the blood
- over time EF is reduced and right ventricle us unable to eject the
normal amount of blood
- the blood remaining in the RV increases and RA preload increases until
the RA is unable to eject the normal amount of blood into the RA
- the amount of blood remaining in the right atrium increases causing an
increase in RA preload
- blood volum enad pressure then backs up into the vena cava and
systemic veins
⩥ signs and symptoms of right sided heart failure. Answer: jugular vein
distension
hepatosplenomegaly
peripheral edema
⩥ Why does hepatosplenomegaly develop in right sided heart failure.
Answer: the large volume of blood flow through the liver and spleen
causes these areas to be engorged
, ⩥ why does peripheral edema occur in right sided heart failure. Answer:
Increased pressure forces fluid from the systemic capillaries into the
peripheral tissues and flood those areas
⩥ High output failure. Answer: inability of the heart to pump sufficient
amounts of blood to meet the circulatory needs of the body despite
normal blood volume and cardiac contractility
⩥ causes of high output failure. Answer: Severe anemia
Nutritional deficiencies
Hyperthyroidism
Sepsis
Extreme febrile state
⩥ Process of high output failure. Answer: - impaired oxygen delivery of
excessive tissue oxygen demands cause tissue hypoxia
- catecholamines initiation increase HR and stroke volume
- increased cardiac output is produced but depletes cardiac muscle
reserve overtime and leads to low output failure over time
