- A.
Posterior interventicular and cicumflex
- B.
Posterior interventicular and marginal
- C.
Anterior interventicular and marginal
- D.
Anterior interventicular and circumflex
Correct Answer
D. Anterior interventicular and circumflexExplanation
The left coronary artery branches into two main arteries: the anterior interventricular artery (also known as the left anterior descending artery) and the circumflex artery. The anterior interventricular artery supplies blood to the anterior part of the interventricular septum and the anterior walls of both ventricles. The circumflex artery supplies blood to the left atrium and the lateral walls of the left ventricle. Therefore, the correct answer is "Anterior interventricular and circumflex."Rate this question:

In the Diagnosis of peptic ulcer disease , one of the following is correct :
- A.
In barium meal study , gastric ulcer biopsy advise r/o malignancyÂ
- B.
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
The correct answer is "In OGD, duodenal ulcer biopsy done to r/o H.pylori." In the diagnosis of peptic ulcer disease, a biopsy of a duodenal ulcer is done during an OGD (esophagogastroduodenoscopy) procedure to rule out the presence of H. pylori bacteria. H. pylori infection is a common cause of duodenal ulcers, and a biopsy can help confirm the presence of the bacteria. This information is important for determining the appropriate treatment plan for the patient.Rate this question:

In laboratory assessment in the Cirrhosis , one of the following is incorrect :
- A.
Alkaline phosphotase increaseÂ
- B.
Serum protein decreaseÂ
- C.
Hematocrit decreaseÂ
- D.
Serum creatinine decreaseÂ
Correct Answer
D. Serum creatinine decreaseÂExplanation
In cirrhosis, the liver is damaged and its function is impaired. This can lead to a decrease in the production of certain proteins, resulting in a decrease in serum protein levels. Additionally, cirrhosis can cause congestion in the liver, leading to an increase in pressure in the portal vein and subsequent fluid accumulation in the abdomen. This can cause a decrease in hematocrit levels. Alkaline phosphatase is an enzyme found in the liver, and its levels can increase in cirrhosis due to liver damage. However, serum creatinine levels are typically increased in cirrhosis due to impaired kidney function, so a decrease in serum creatinine would be incorrect.Rate this question:

Physical symptoms of psychotogical origins is :
- A.
Arrhythmia
- B.
Hypochondriasis
- C.
Thyroid disease
- D.
Hyperlipedimia
Correct Answer
B. HypochondriasisExplanation
Hypochondriasis refers to a psychological disorder in which individuals excessively worry about having a serious medical condition despite having no or minimal medical evidence to support their concerns. This disorder is characterized by the presence of physical symptoms that are primarily caused by psychological factors rather than any actual underlying medical condition. Therefore, hypochondriasis is the correct answer as it specifically relates to physical symptoms of psychological origins. Arrhythmia, thyroid disease, and hyperlipidemia, on the other hand, are medical conditions that have physiological causes rather than psychological origins.Rate this question:

One of the following is incorrect about Metabolic syndrome :
- A.
Hypotension
- B.
Low HDL
- C.
Elevated triglyceride levels
- D.
Impaired fasting glucose
Correct Answer
A. HypotensionExplanation
Hypotension is not a characteristic of metabolic syndrome. Metabolic syndrome is a cluster of conditions that includes elevated blood pressure, high blood sugar levels, abnormal cholesterol levels (low HDL and elevated triglycerides), and excess abdominal fat. Hypotension, on the other hand, refers to low blood pressure. Therefore, hypotension is incorrect in relation to metabolic syndrome.Rate this question:

About the drugs that used in treatment of peptic ulcer disease , one of the following drugs considered a prostaglandin analogue :
- A.
Tums
- B.
Cimetioline
- C.
Lansoprazole
- D.
Misoprostol
Correct Answer
D. MisoprostolExplanation
Misoprostol is considered a prostaglandin analogue used in the treatment of peptic ulcer disease. Prostaglandins are natural substances produced in the body that help protect the stomach lining. Misoprostol works by replacing these natural prostaglandins, reducing the production of stomach acid and promoting the healing of ulcers. Tums, Cimetidine, and Lansoprazole are not prostaglandin analogues and have different mechanisms of action in treating peptic ulcer disease.Rate this question:

Elevated Jugular Venous pressure is :
- A.
Ankle edema
- B.
Pleural effusion
- C.
Kussmauls's sign
- D.
Ascites
Correct Answer
C. Kussmauls's signExplanation
Kussmaul's sign refers to an abnormal increase in jugular venous pressure during inspiration, instead of the normal decrease. It is commonly seen in conditions such as constrictive pericarditis, cardiac tamponade, and severe right-sided heart failure. This sign is characterized by a paradoxical rise in the jugular venous pressure with inspiration, indicating impaired filling of the right ventricle. Ankle edema, pleural effusion, and ascites are not associated with elevated jugular venous pressure.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 and is an octapeptide composed of 8 amino acids. It is produced in the body through a cascade of reactions involving renin, angiotensinogen, and angiotensin-converting enzyme (ACE). Angiotensin II acts on blood vessels to constrict them, leading to an increase in blood pressure. It also stimulates the release of aldosterone and ADH, which further contribute to fluid retention and vasoconstriction. Therefore, Angiotensin II is the correct answer as it fits the description of being a potent vasoconstrictor and an octapeptide.Rate this question:

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 exudative mechanism of diarrhea involves the output of purulent and bloody stool. This means that the stool contains pus and blood, indicating inflammation and infection in the gastrointestinal tract. This type of diarrhea is often associated with conditions such as inflammatory bowel disease, infection, or certain medications. The presence of purulent and bloody stool suggests that there is damage to the lining of the intestines, leading to the release of inflammatory cells and blood into the stool.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 ensures that organs such as the brain, heart, and lungs receive adequate blood supply to continue functioning properly, even in a state of shock.Rate this question:

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 main explanatory reasons for the Berserk movement in fibrillation are a decrease in velocity and an increase in the refractory period. This means that the electrical signals in the heart are slowing down and taking longer to recover, leading to irregular and chaotic contractions. This can result in a rapid and uncoordinated heartbeat, which is characteristic of 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 cyclase converts ATP to cAMP." Adenylate cyclase is an enzyme that catalyzes the conversion of ATP to cyclic AMP (cAMP) in response to the activation of G protein-coupled receptors (GPCRs). This conversion is an important step in many signaling pathways, as cAMP acts as a second messenger to regulate various cellular processes. Protein kinase A (PKA) is then activated by cAMP and plays a role in downstream signaling events.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
An increase in trans pulmonary pressure leads to a decrease in the volume of air inside the lungs. This is because trans pulmonary pressure is the difference between intra alveolar pressure (pressure inside the alveoli) and intra pleural pressure (pressure in the pleural cavity). When the trans pulmonary pressure is higher, it means that the alveolar pressure is greater than the pleural pressure, causing the lungs to expand and the volume of air inside them to decrease. Therefore, the statement "More trans pulmonary pressure, less volume of air inside the lungs" is correct.Rate this question:

One of the following is like coffee ground vomit :
- A.
Chronic cough
- B.
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 interaction between stomach acid and blood. This can occur as a result of various conditions, such as peptic ulcers, gastritis, or esophageal varices. The other options, chronic cough, acute cough, and hemoptysis, do not involve the presence of blood in the vomit. Chronic cough refers to a persistent cough lasting for more than 8 weeks, while acute cough is a sudden, short-term cough. Hemoptysis, on the other hand, refers to coughing up blood from the respiratory tract.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, or Chronic Obstructive Pulmonary Disease, usually represents a high V/Q (ventilation/perfusion) ratio in pulmonary tests. This is because in COPD, there is a decrease in airflow through the airways, leading to inadequate ventilation. However, perfusion (blood flow) to the lungs remains relatively normal. As a result, the V/Q ratio becomes imbalanced, with a higher ratio indicating a higher ventilation compared to perfusion. This imbalance is typically seen in COPD patients, making it the correct answer.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, the major events that occur include bronchiolar constriction, inflammatory swelling, and mucus hypersecretion. These events lead to the obstruction of the airways and difficulty in breathing. However, hyperinflation of alveoli is not a major event in an acute asthma attack. Hyperinflation of alveoli refers to the increased volume of air in the alveoli, which is typically seen in conditions like emphysema. In asthma, the focus is on the constriction of the bronchioles and the inflammation of the airways, rather than the hyperinflation of alveoli.Rate this question:

- A.
SABA
- B.
Ventilation
- C.
MgSO4
- D.
LABA
Correct Answer
C. MgSO4Explanation
MgSO4, also known as magnesium sulfate, acts as a bronchodilator and causes relaxation of smooth muscle by acting as a calcium antagonist. This means that it blocks the entry of calcium into smooth muscle cells, leading to muscle relaxation and widening of the airways in the bronchial tubes. As a result, MgSO4 can be used to treat bronchospasm and improve airflow in conditions such as asthma and chronic obstructive pulmonary disease (COPD).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 lung condition characterized by the destruction of the alveoli, which are responsible for gas exchange. This leads to impaired oxygen uptake and carbon dioxide elimination. However, in emphysema, the loss of lung tissue also results in increased dead space, allowing for more efficient carbon dioxide elimination. As a result, the PaCO2 levels remain within the normal range.Rate this question:

The first line of treatment of high blood pressure :
- A.
Beta blockers
- B.
Calcium antagonist
- C.
Diuretics
- D.
Angiotensin || receptor blockers
Correct Answer
C. DiureticsExplanation
Diuretics are the first line of treatment for high blood pressure because they help to reduce the volume of fluid in the blood vessels, thereby lowering blood pressure. They work by increasing the excretion of sodium and water from the body through the kidneys. This helps to decrease the amount of fluid in the bloodstream, which in turn reduces the pressure on the blood vessel walls. Diuretics are considered effective and safe for most people with high blood pressure, making them a commonly prescribed medication for initial treatment.Rate this question:

Happens in athletes because cardiomegaly :
- A.
Bradycardia physiology
- B.
Bradycardia pathophysiology
- C.
Tachycardia physiology
- D.
Tachycardia Pathophysiology
Correct Answer
A. Bradycardia physiologyExplanation
Bradycardia refers to a slower than normal heart rate, which can occur in athletes due to cardiomegaly, or an enlarged heart. In athletes, the heart muscle becomes stronger and more efficient, allowing it to pump blood more effectively with each beat. This increased efficiency leads to a lower resting heart rate, resulting in bradycardia. This physiological adaptation is a normal response to regular exercise and is not typically associated with any negative health effects.Rate this question:

- B.
Acetylcholine
- C.
Epinephrine and norepinephrine
- D.
A1,A2,B1,B2
Correct Answer
C. Epinephrine and norepinephrineExplanation
Epinephrine and norepinephrine are examples of sympathetic postganglionic neurotransmitters. These neurotransmitters are released by the postganglionic neurons of the sympathetic nervous system and are responsible for activating the fight-or-flight response in the body. Epinephrine and norepinephrine bind to adrenergic receptors, specifically the A1, A2, B1, and B2 receptors, to elicit various physiological responses such as increased heart rate, elevated blood pressure, and dilation of bronchioles.Rate this question:
