In OGD , duodenal ulcer shows trifoliteÂ
- C.
In OGD , duodenal ulcer biopsy done to r/o H.pylori
- D.
In barium meal study , duodenal ulcer appears as niche in lesser curvature due to ulcer craterÂ
Correct Answer
C. In OGD , duodenal ulcer biopsy done to r/o H.pyloriExplanation
In the diagnosis of peptic ulcer disease, performing a duodenal ulcer biopsy during an OGD (oesophagogastroduodenoscopy) is correct to rule out the presence of H. pylori bacteria. H. pylori infection is a common cause of peptic ulcers, and obtaining a biopsy sample allows for testing to determine if the bacteria is present. This information is important for guiding treatment decisions, as eradicating H. pylori is necessary for successful management of peptic ulcers.Rate this question:

One of the most potent vasoconstrictors known and it is an octapeptides ( 8 amino acids ) :
- A.
Aldosteron
- B.
Renin
- C.
ADH
- D.
Angiotemsin ||
Correct Answer
D. Angiotemsin ||Explanation
Angiotensin II is a potent vasoconstrictor that plays a crucial role in regulating blood pressure. It is formed from angiotensin I through the action of the enzyme ACE (angiotensin-converting enzyme). Angiotensin II acts on blood vessels, causing them to constrict, which leads to an increase in blood pressure. This vasoconstriction helps to maintain blood flow to vital organs, especially in situations where blood volume is low or blood pressure is reduced. Additionally, angiotensin II stimulates the release of aldosterone, a hormone that promotes sodium and water reabsorption in the kidneys, further contributing to an increase in blood pressure.Rate this question:

Regard to principals mechanisms of diarrhea , the Exudative mechanism include :
- A.
Excessive osmotic forcesÂ
- B.
Output of purulent and bloody stool
- C.
Voluminous stool and defective absorptionÂ
- D.
Isotonic tp plazmaÂ
Correct Answer
B. Output of purulent and bloody stoolExplanation
The correct answer is "Output of purulent and bloody stool." In the context of the question, the exudative mechanism of diarrhea refers to the presence of purulent (pus-filled) and bloody stool. This suggests an inflammatory process in the gastrointestinal tract, leading to the release of inflammatory exudate into the stool. This mechanism is different from excessive osmotic forces, voluminous stool, and defective absorption, which are associated with other types of diarrhea. The presence of purulent and bloody stool indicates an underlying infection or inflammation in the intestines.Rate this question:

Regard to Portal Systemic Encephalopathy (hepatic coma) , the incorrect one is :
- A.
Acute diseaseÂ
- B.
Reversible with early interventionÂ
- C.
Causes impaired thinkingÂ
- D.
Caused by Decrease ammonia levelsÂ
Correct Answer
D. Caused by Decrease ammonia levelsÂExplanation
Portal Systemic Encephalopathy (hepatic coma) is a condition that occurs due to liver dysfunction, specifically in cases of advanced liver disease. It is characterized by impaired brain function and mental changes. The correct answer states that it is caused by a decrease in ammonia levels, which is incorrect. In fact, Portal Systemic Encephalopathy is caused by an increase in ammonia levels in the blood, as the liver is unable to properly process and eliminate ammonia. This leads to toxic levels of ammonia in the brain, resulting in the symptoms associated with the condition.Rate this question:

In compensented shock , one of the following is peripheral effects :
- A.
Increase cardiac output
- B.
Shunting of blood to main core organs
- C.
Decrease blood flow to the hypothalamus
- D.
ACTH
Correct Answer
B. Shunting of blood to main core organsExplanation
In compensated shock, the body tries to maintain blood flow to vital organs by shunting blood away from less essential areas. This is known as shunting of blood to main core organs. This mechanism helps to ensure that organs like the heart, brain, and kidneys receive an adequate supply of oxygen and nutrients, despite the decreased overall blood flow. This peripheral effect is an important adaptive response in the body's attempt to compensate for the reduced cardiac output and maintain organ function.Rate this question:

Main explanatory reasons for Berserk movement in fibrillation :
- A.
Decrease velocity and increase refractory period
- B.
Decrease velocity and decrease refractory period
- C.
Increase velocity and decrease refractory period
- D.
Increase velocity and increase refractory period
Correct Answer
A. Decrease velocity and increase refractory periodExplanation
The correct answer is "Decrease velocity and increase refractory period." In fibrillation, the heart muscle contracts in an uncoordinated manner, leading to a rapid and irregular heartbeat. Decreasing the velocity of the electrical signals in the heart can help to prevent the abnormal contractions from spreading too quickly. Additionally, increasing the refractory period, which is the time during which the heart muscle cannot be stimulated again, can help to regulate the heartbeat and prevent further chaotic contractions. Therefore, decreasing velocity and increasing refractory period are the main explanatory reasons for the Berserk movement in fibrillation.Rate this question:

Regard to alpha stimulatory in G protein coupled receptor , the correct one is :
- A.
Alpha work on protein kinase A
- B.
Protein kinase A converts ATP to CAMP
- C.
Enzyme adenine cyclise converts ATP to CAMP
- D.
No adenine cyclise
Correct Answer
C. Enzyme adenine cyclise converts ATP to CAMPExplanation
The correct answer is "Enzyme adenine cyclise converts ATP to CAMP". This is because adenylate cyclase is an enzyme that catalyzes the conversion of ATP (adenosine triphosphate) to cAMP (cyclic adenosine monophosphate). cAMP is an important secondary messenger molecule that regulates various cellular processes, including signal transduction pathways mediated by G protein-coupled receptors (GPCRs). Therefore, in the context of alpha stimulation in GPCRs, adenylate cyclase plays a crucial role in converting ATP to cAMP, which then activates downstream signaling pathways.Rate this question:

One of the following is incorrect about trans pulmonary pressure :
- A.
More trans pulmonary pressure , less volume of air inside the lungsÂ
- B.
Becomes a zero at death
- C.
Difference between a intra alveolar and intra pleural pressureÂ
- D.
Becomes zero in PneumothoraxÂ
Correct Answer
A. More trans pulmonary pressure , less volume of air inside the lungsÂExplanation
Trans pulmonary pressure refers to the difference between intra-alveolar and intra-pleural pressure. When the trans pulmonary pressure increases, it causes the expansion of the lungs, resulting in an increase in the volume of air inside the lungs. Therefore, the statement "More trans pulmonary pressure, less volume of air inside the lungs" is incorrect.Rate this question:

Hematemesis
- C.
Acute cough
- D.
Hemoptysis
Correct Answer
B. HematemesisExplanation
Hematemesis refers to the vomiting of blood, which can appear similar to coffee grounds due to the digestion of blood in the stomach. This condition is often associated with gastrointestinal bleeding and can be caused by various factors such as ulcers, liver disease, or esophageal varices. Chronic cough, acute cough, and hemoptysis are not related to the appearance of coffee ground vomit.Rate this question:

One of the following diseases usually represents a high V/Q ratio in pulmonary test :
- A.
Acute pulmonary edema
- B.
Asthma
- C.
COPD
- D.
Chronic bronchitis
Correct Answer
C. COPDExplanation
COPD (Chronic Obstructive Pulmonary Disease) usually represents a high V/Q (ventilation/perfusion) ratio in pulmonary tests. This is because COPD is characterized by airflow limitation and obstruction in the lungs, which leads to decreased ventilation in relation to perfusion. In other words, there is inadequate airflow to match the blood flow in the lungs, resulting in a high V/Q ratio. This imbalance can cause impaired gas exchange and difficulty breathing in individuals with COPD.Rate this question:

In acute asthma attack , One of the following is not major event :
- A.
Bronchiolar constriction
- B.
Inflammatory swelling
- C.
Mucus hepersecretion
- D.
Hyperinflation of alveoli
Correct Answer
D. Hyperinflation of alveoliExplanation
During an acute asthma attack, bronchiolar constriction, inflammatory swelling, and mucus hypersecretion are major events that contribute to the narrowing of the airways and difficulty in breathing. However, hyperinflation of alveoli is not a major event in acute asthma attacks. Hyperinflation refers to the excessive expansion of the alveoli, which is not typically observed in asthma attacks. Instead, the focus is on the constriction and inflammation of the airways, as well as the increased production of mucus, leading to airway obstruction.Rate this question:

- A.
SABA
- B.
Ventilation
- C.
MgSO4
- D.
LABA
Correct Answer
C. MgSO4Explanation
MgSO4 refers to magnesium sulfate, which acts as a bronchodilator and causes relaxation of smooth muscle by acting as a calcium antagonist. This means that it helps to open up the airways and relieve symptoms of bronchospasm. SABA and LABA are also bronchodilators, but they work through different mechanisms. Ventilation, on the other hand, refers to the process of breathing and is not directly related to bronchodilation.Rate this question:

Patients with a predominant emphysema usually have :
- A.
Hepercapnia
- B.
Edema
- C.
Normal PaCO2
- D.
Polycythemia
Correct Answer
C. Normal PaCO2Explanation
Patients with a predominant emphysema usually have normal PaCO2 levels. Emphysema is a chronic lung condition characterized by the destruction of the alveoli, leading to decreased lung function. In emphysema, the ability to exhale fully is impaired, resulting in air trapping and increased residual volume. However, the PaCO2 levels remain normal because the patient can still effectively eliminate carbon dioxide. This is in contrast to conditions such as chronic bronchitis, where the PaCO2 levels are elevated due to impaired carbon dioxide elimination.Rate this question:

Correct Answer
C. DiureticsExplanation
Diuretics are the first line of treatment for high blood pressure because they help the body get rid of excess salt and water, reducing the volume of blood and thus lowering blood pressure. They are effective in treating hypertension and are often prescribed as initial therapy due to their proven efficacy and safety profile. Diuretics work by increasing urine production, which helps to decrease the amount of fluid in the blood vessels, leading to a decrease in blood pressure. They are commonly used in combination with other antihypertensive medications to achieve optimal blood pressure control.Rate this question:
