One specific ECG change in hypokalemia (low potassium level) is :

U wave (a positive deflection after the T wave)

ST segment elevation

Tall peaked T waves

Increased amplitude and widening of the QRS complex.

Correct! Wrong!

The classic ECG changes in myocardial infarction (MI) are :

T- wave

ST- segment elevation

Development of an abnormal wave

Correct! Wrong!

Pinna is a shell-like structure which is a part of :

Inner ear

Outer ear

Middle ear

None of them

Correct! Wrong!

A thin, semi-transparent, flexible membrane is known as :

Pinna

Ear drum

Ear canal

Ear lobe

Correct! Wrong!

Sound waves are :

Longitudinal

Transverse

Correct! Wrong!

Sound is produced due to :

Refraction

Vibration

Circulation

Friction

Correct! Wrong!

If at one end, the two wires made of different metals are joined together then a voltage will get produced between the two wires due to difference of temperature between the two ends of wires. This effect is observed in :

Thermistors

RTD

Ultrasonics

Thermocouples

Correct! Wrong!

The linear variable differential transformer transducer is :

Inductive transducer

Non-inductive transducer

Capacitive transducer

Resistive transducer

Correct! Wrong!

Strain gauge is a :

Active device and converts mechanical displacement into a change of resistance

Passive device and converts electrical displacement into a change of resistance

Passive device and converts mechanical displacement into a change of resistance

Active device and converts electrical displacement into a change of resistance

Correct! Wrong!

Function of transducer is to convert :

Electrical signal into non electrical quantity

Electrical signal into mechanical quantity

Non electrical quantity into electrical signal

All of these

Correct! Wrong!

The most common type of defect of the cardiac septa is :

Muscular ventricular septal defect

Primum atrial septal defect

Secundum atrial septal defect

Membranous ventricular septal defect

Correct! Wrong!

The heart is made up of which type of muscle :

Skeletal muscle

Cardiac muscle

Smooth muscle

Elastic muscle

Correct! Wrong!

Following a motor vehicle accident, a large loss of blood will initially cause :

A lowered BP due to a decreased cardiac output

No change in BP but a slower heart rate

A higher BP due to an increased stroke volume

No change in BP but an increased respiration rate

Correct! Wrong!

When aortic pressure is greater than the ventricular pressure :

The pulmonary semilunar valve opens

The aortic semilunar valve closes

The bicuspid/mitral atrioventricular valve closes

The tricuspid atrioventricular valve opens

Correct! Wrong!

On a normal ECG/EKG, ventricular depolarization occurs during the :

P Wave

T wave

QRS complex

P-Q interval

Correct! Wrong!

During systemic circulation, blood leaves the (i) and (ii) .

(i) Left ventricle, (ii) goes directly to the aorta

(i) Right ventricle, (ii) moves to the lungs

(i) Right ventricle, (ii) goes directly to the aorta

(i) Left ventricle, (ii) moves to the lungs

Correct! Wrong!

In order for the blood to flow from right ventricle to left ventricle in mammalian heart, it must flow through : (i) Right ventricle (ii) Pulmonary veins (iii) Left atrium (iv) Lungs (v) Pulmonary arteries

(i), (v), (iv), (ii), (iii)

(i), (ii), (iii), (iv), (v)

(iii), (v), (i), (ii), (iv)

(iii), (ii), (i), (iv), (v)

Correct! Wrong!

Cardiac output is determined by :

Heart rate

Stroke volume

Blood flow

Both (A) and (B)

Correct! Wrong!
