  2. Tactile venous palpation.

  3. Capillary palpation.

  4. None of the above.

A Correct answer
Explanation

The rate at which the heart beats is pulse rate. As the heart pumps blood through the body, the pulse can be felt in some of the blood vessels close to the surface of the skin such as wrist, neck or upper arm. Hence pulse represents tactile arterial palpation. Thus the correct answer is option A.

The normal pulse for healthy individual ranges from 

  1. 20-40 beats/minute.

  2. 200-600 beats/minutes.

  3. 60-100 beats/minutes.

  4. 90 beats/minute.

C Correct answer
Explanation

  • Pulse is a pressure wave that travels through the arteries after each ventricular systole.
  • Since each heartbeat generates one pulse in the arteries, the pulse rate per minute indicates the heart rate.
  • Thus, pulse rate is the same as that of heart rate, between 60 to 100 beats per minute. 
Thus option C is the correct answer.

Pulse can be palpated from 

  1. Carotid artery

  2. Radial artery

  3. Femoral artery

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pulse is a pressure wave that travels through the arteries after each ventricular systole. The pulse can be felt in any artery that lies near the surface of the body. Carotid artery (neck region), radial artery (forearm) and femoral artery (legs) all of them are situated near the surface of the body. Thus pulse can be palpated from all of them.

So, the correct answer is option D.

The rhythmic contraction and relaxation of heart muscles makes a

  1. Heart stroke

  2. Heart rate

  3. Heart beat

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The heart is pumping organ of human body and is situated in the thoracic cavity in the space between two lungs which is known as mediastinum. Heartbeat is rhythmic contraction and relaxation of heart muscles is called as a heart beat. Heart rate is the speed of heart beat measured by a number of contraction of the heart per minute. There is no term like heart stroke. When the blood vessel supplying blood to the brain are clogged it is known as brain stroke. Thus the correct answer is C.

The relationship between the heartbeat and the pulse rate is 

  1. One heart beat generate two pulse

  2. Two heart beat generate one pulse

  3. One heart beat generate one pulse

  4. One heart beat generate three pulse
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
This sequential event in the heart which is cyclically repeated is called the cardiac cycle. Each cardiac cycle consists of systole and diastole of both the atria and ventricles. Each cardiac cycle represents one heartbeat. The normal heart rate is about 72 beats per minute. The heart rate is same as pulse rate because the pumping action of the heart causes an increase in blood pressure in arteries that leads to noticeable pulse. Hence the relationship between the heartbeat and the pulse rate is one heartbeat generates one pulse.
So, the correct answer is 'One heartbeat generate one pulse'.

Rubber tube, ear piece and diaphragm are parts of a

  1. Headphone

  2. Microphone

  3. Periscope

  4. Stethoscope
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The stethoscope is an acoustic (hearing) medical device used for auscultation(listening of internal sounds of the body. The doctor will place a small metal circle called a bell (hallow disc) or diaphragm (plastic disc), against the chest, at the spot where a person can feel the heartbeat. The stethoscope is composed of rubber tube, earpiece and diaphragm.

So, the correct answer is 'Stethoscope'.

The heart is protected by the

  1. Diaphragm

  2. Rib cage

  3. Skull

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The human circulatory system consists of a muscular four-chambered heart, a network of closed branching blood vessels and blood, the fluid which is circulated. The heart is mesodermal in origin. It is situated in the thoracic cavity, in between the two lungs. The rib cage partially encloses and protect chest cavity. In the chest cavity heart and lungs are present. Hence, the heart is protected by the rib cage.

So, the correct answer is 'Ribcage'.

  1. Wollen tube

  2. Iron tube

  3. Rubber tube

  4. Plastic tube
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A stethoscope requires a flexible tube to transmit sound waves from the chest piece to the earpieces. Rubber is the standard material due to its flexibility and acoustic properties.
