১.
Which one is called pacemaker of heart?
  1. ক
    SA node
  2. খ
    AV node
  3. গ
    Bundle of His
  4. ঘ
    Purkinje fibre
ব্যাখ্যা

Explanation:
The normal pacemaker tissue of the heart is the SA node because:
• SA node has the highest automaticity (discharge rate 70 -100 bpm.)
• Each natural heart beat begins in the SA node
• The SA node maintains normal cardiac rhythm

২.

  3. গ
    TLC
  4. ঘ
    FRV

In Pulsus bigeminy there is abnormality in
  1. ক
    Rate
  2. খ
    Rythm
  3. গ
    Volume
  4. ঘ
    Condition of vessel wall
ব্যাখ্যা
Explanation:
Pulses bigeminy: This is due to premature ectopic beats following every sinus beat. The pulse rhythm is not regular because every weak pulse is premature.
৪.
Helium Dilution method is used to measure all of the following except
  1. ক
    Functional residual capacity
  2. খ
    Residual volume
  3. গ
    Vital capacity

৫.
At a normal heart rate the duration(second) of atrial systole is
  1. ক
    0.1
  2. খ
    0.3
  3. গ
    0.5
  4. ঘ
    0.7
ব্যাখ্যা
Explanation:
At a normal heart rate the duration of systole and diastole are:
Atrial systole: 0.1 second
Atrial diastole: 0.7 second
Ventricular systole: 0.3 second
Ventricular diastole: 0.5 second
৬.
The three major organs of articulation excludes
  1. ক
    Lips
  2. খ
    Tongue
  3. গ
    Soft palate
  4. ঘ
    Hard plate
ব্যাখ্যা
Reference: Guyton 14th; P- 501
৭.
Ejection click occurs following which heart sound?
  1. ক
    1st
  2. খ
    2nd
  3. গ
    3rd
  4. ঘ
    4th
ব্যাখ্যা
Explanation:
Ejection click: an ejection click sound occurs immediately following the first heart sound. The sudden opening of a deformed but mobile aortic or pulmonary valve produces the ejection click.
৮.
The blood volume of the lungs is about...ml
  1. ক
    450(9%)
  2. খ
    500(10%)
  3. গ
    550(11%)
  4. ঘ
    600(12%)
ব্যাখ্যা
Reference: Guyton 14th; P- 504
৯.
Viscosity is decreased in
  1. ক
    Severe anaemia
  2. খ
    Polycythaemia Hereditary
  3. গ
    Spherocytosis
  4. ঘ
    Excess immunoglobulins in blood
ব্যাখ্যা

Explanation:
Viscosity is increased in
• Polycythaemia Hereditary
• Spherocytosis
• Excess immunoglobulins in blood
Viscosity is decreased in
• Severe anaemia

১০.
BP on lower limb is measured over
  1. ক
    Anterior tibial artery
  2. খ
    Posterior tibial artery
  3. গ
    Popliteal artery
  4. ঘ

• Thighs (over popliteal artery)

১১.
Rapidly acting BP regulating mechanisms excludes
  1. ক
    Baroreceptor mechanism
  2. খ
    Chemoreceptor mechanism
  3. গ
    Renin angiotensin mechanism
  4. ঘ
    CNS ischemic mechanism
ব্যাখ্যা

Explanation:
Rapidly acting regulating mechanisms (acute nervous reflexes) (acts within seconds to minutes)
• Baroreceptor mechanism
• Chemoreceptor mechanism
• CNS ischemic mechanism
