Some very important MCQ for MCI scr

Hello Friends
These are some very important Mcq try them ,i will try to publish
more,if you find them useful leave the comment

Question 1. The pulse:
(a) In pulsus paradoxus the rate slows during inspiration. (False)
(b) Pulsus alternans indicates a poorly functioning left ventricle. (True)
(c) A tachycardia of 150 beats per minute in a resting patient usually
implies an underlying cardiac arrhythmia. (True)
(d) A collapsing pulse may be noticed in thyrotoxicosis. (True)
(e) Corrigan's sign supports a diagnosis of aortic stenosis. (False)
Question 2. Heart murmurs:
(a) A low rumbling diastolic murmur with presystolic accentuation may be
heard in mitral stenosis accompanied by
atrial fibrillation. (False)
(b) Causes of a pansystolic murmur include mitral regurgitation and
ventricular septal defect. (True)
(c) A systolic murmur heard over the whole praecordium associated with a
thrill usually indicates aortic stenosis.
(True)
(d) Left heart murmurs are best heard during expiration. (True)
(e) An early blowing diastolic murmur at the left sternal edge indicates
aortic incompetence. (True)
Question 3. Pulsus paradoxus:
(a) The volume of the pulse increases in inspiration. (False)
(b) Can be confirmed by detecting >10 mmHg difference in systolic
pressure during the breathing cycle. (True)
(c) Is a sign of severe asthma. (True)
(d) Is called paradoxus because it is the opposite of what normally
happens to the pulse. (False)
(e) Can occur in cardiac tamponade. (True)
Question 4. The jugulovenous pressure:
(a) Is raised if it is 2 cm from the sternal angle with the patient
seated at 45°. (False)
(b) Tall 'a' waves may be seen in pulmonary hypertension. (True)
(c) Irregular cannon waves indicate complete heart block. (True)
(d) Regular cannon waves may indicate a nodal rhythm. (True)
(e) Giant 'v' waves and a pulsatile liver indicate tricuspid stenosis.
(False)
Question 5. The physical signs of an uncomplicated large pneumothorax
include:
(a) The trachea deviated to the opposite side. (False)
(b) A clicking sound synchronous with the heart beat. (True)
(c) Symmetrical expansion of the chest. (False)
(d) Increased breath sounds over the pneumothorax. (False)
(e) Increased percussion note over the pneumothorax. (True)
Question 6. The following would help distinguish between a kidney and a
spleen in the left upper quadrant:
(a) Dull to percussion over the mass. (False)
(b) A well-localized notched lower margin. (False)
(c) Moves with respiration. (False)
(d) A ballottable mass. (True)
(e) A family history of renal failure. (True)
Question 7. Nystagmus:
(a) Vertical nystagmus usually indicates a lesion of the medulla
oblongata. (False)
(b) Horizontal nystagmus is usually ipsilateral to an irritative lesion
of the labyrinth. (False)
(c) Ataxic nystagmus indicates a lesion of the medial longitudinal
bundle. (True)
(d) May be absent in a lesion of the cerebellar vermis (the central
part). (True)
