A Correct answer
Explanation

A sphygmomanometer is an instrument attached to an inflatable air bladder cuff and used with a stethoscope, for measuring blood pressure in an artery. It is estimated with reference to mmHg.

So, the correct answer is option A.

The instrument used for measuring blood pressure is known as

  1. ECG.

  2. Stethoscope.

  3. Sphygmomanometer.

  4. EEG.

C Correct answer
Explanation
The instrument used for measuring blood pressure is known as sphygmomanometer. The blood pressure in the measured in mm of Hg (millimetres of mercury) and recorded with systolic number first followed by diastolic. A normal blood pressure recorded would be 120/80 mm Hg.
So, the correct answer is 'Sphygmomanometer'.

In a normal adult, BP is

  1. 100/80 mm of Hg

  2. 120/80 mm of Hg

  3. 100/120 mm of Hg

  4. 80/120 mm of Hg

B Correct answer
Explanation

The instrument used for measuring blood pressure is known as sphygmomanometer. The blood pressure is measured in mm of Hg (millimetres of mercury) and recorded with systolic number first followed by diastolic. In a normal adult, BP is 120/80 mm Hg.

So, the correct answer is '120/80 mm of Hg.

A Correct answer
Explanation
A. Sphygmomanometer is an instrument that measures blood pressure.
B. Phonocardiogram is a record or plot of sounds of heart.
C. Electrocardiogram is a record of electrical activity or the electric current that moves through the heart during a heart beat.
D. Stethoscope is a device by which internal sounds of body are heard.
So, the correct answer is 'Sphygmomanometer'.

The value of diastolic blood pressure is

  1. 120 mm Hg

  2. 80 mm Hg

  3. 120/80 mm Hg

  4. 40 mm Hg
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
There are two components of blood pressure, systolic and diastolic blood pressure.
  • Systolic pressure is the pressure in blood vessels or the force of blood against the wall of arteries when the ventricles pump out blood into them. It is about 120 mm Hg.
  • Diastolic pressure is the pressure or the force of blood against the wall of arteries when the heart is relaxing and getting refilled with blood. It is about 80 mm Hg.
So, the correct answer is '80 mm Hg'.

Blood pressure is controlled by

  1. Thyroid gland

  2. Adrenal gland

  3. Thymus gland

  4. Parathyroid gland.

B Correct answer
Explanation

The adrenal glands, specifically through the secretion of hormones like aldosterone and adrenaline, play a critical role in regulating blood pressure. Aldosterone helps regulate blood volume by managing sodium and water retention.

Hypotension may not be due to

  1. Loss of fluid

  2. Loss of blood

  3. Endocrine disorder

  4. Excessive fluid intake.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Hypotension (low blood pressure) is often caused by fluid loss, blood loss, or endocrine issues. Excessive fluid intake would typically increase blood volume and potentially raise blood pressure rather than lower it.

In normal blood pressure of 120/80 mm Hg, the numerator represents

  1. Diastolic pressure

  2. Systolic pressure

  3. Pulse pressure

  4. Cardiac index.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In a blood pressure reading of 120/80, the top number (120) is the systolic pressure, which is the pressure during heart contraction. The bottom number (80) is the diastolic pressure.

First sound recorded in sphygmomanometer indicates

  1. Systolic pressure

  2. Diastolic pressure

  3. Lubb

  4. Dup.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

When using a sphygmomanometer, the first sound heard (Korotkoff sound) as the cuff pressure is released corresponds to the systolic pressure. This is when the blood first begins to flow through the artery again.
