Primary treatment reduces BOD, ranges from;

  1. 30-60%

  2. 0-70%

  3. 30-35%

  4. 20-80%
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Primary treatment in wastewater treatment typically reduces BOD by about 30-35% through physical processes like screening and sedimentation. This level of reduction is consistent with standard wastewater treatment engineering data. Higher reductions (like 30-60% or more) usually require secondary treatment with biological processes.

According to National Family Health Survey-4 2015-16 (NFHS-4), rural women of Karnataka have a Body Mass Index (BMI) of _______.

  1. 24.3

  2. 16.2

  3. 30

  4. 21.4
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The National Family Health Survey (NFHS) is a large-scale, multi-round survey conducted in a representative sample of households throughout India. The Fourth National Family Health Survey (NFHS-4) was carried out in 2014-2015.NFHS-4 is the first survey in the NFHS series that has collected data from all 29 States and all 7 Union Territories. Body Mass Index (BMI) is a person’s weight in kilograms divided by the square of height in meters. A high BMI can be an indicator of high body fatness. NFHS-4 provides that women in Karnataka have 24.2% BMI.

Which one of the following statements is correct regarding blood pressure?

  1. 130/90 mm Hg is considered high and requires treatment.

  2. 100/55 mm Hg is considered an ideal blood pressure.

  3. 105/50 mm Hg makes one very active.

  4. 190/110 mm Hg may harm vital organs like brain and kidney.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The blood pressure above 140/90 mm Hg is considered a high blood pressure and recurrent such values of an individual’s blood pressure can indicate hypertension. Blood pressure with more than values 190/110 mm Hg can have disastrous effects on the kidney and the brain.
Thus, the correct answer is '190/110 mm Hg may harm vital organs like brain and kidney.'

Normal systolic and diastolic value of blood pressure is

  1. 80/120 mm Hg

  2. 80/40 mm Hg

  3. 140/80 mm Hg

  4. 120/80 mm Hg
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A) Blood pressure is always read as systolic/diastolic pressure. Systolic pressure is 120 mm Hg while diastolic pressure is 80 mm Hg.

B) The systolic pressure is 120 mm Hg while diastolic pressure is 80 mm Hg.
C) Systolic pressure is 120 mm Hg.
D) 120 mm Hg here, represents the systolic pressure and 80 mm Hg represents the diastolic pressure.
So the correct answer is '120/80 mm Hg'.

Which one of the following statements is correct regarding blood pressure?

  1. $130/90 $ mm Hg is considered as high and requires treatment.
  2. $100/55 $ mm Hg is considered ideal blood pressure.
  3. $105/50 $ mm Hg makes one very active.
  4. $190/110 $ mm Hg may harm vital organs like brain and kidney.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The normal range of blood pressure is 120/80. Blood pressure higher than this leads to hypertension. High blood pressure affects the walls of arteries that carry the blood to the vital organs and cause the tear in the walls.
Bad cholesterol from bloodstream gets trapped in the torn walls and starts building there thus narrowing the arteries wall. When the proper amount of blood can’t move through a blocked artery, it causes damage to the tissue or organ. it’s supposed to reach. When a larger blockage of blood to the brain occurs, it’s called a stroke. If parts of the brain can’t get the oxygen they receive from blood, cells begin to die. High blood pressure damage the larger blood vessels can lead to kidney failure. Thus, the correct answer is option D.

Systolic pressure in a normal human is

  1. $70$ mm of Hg
  2. $80$ mm of Hg
  3. $90$ mm of Hg
  4. $120$ mm of Hg
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Blood pressure is measured in 2 categories, systolic blood pressure and diastolic blood pressure. The systolic pressure is the amount of pressure in the arteries during the contraction of the heart muscle. The diastolic pressure is the pressure during the resting period between heartbeats. The normal value of systolic pressure in human is 120 mm of Hg. The normal value of diastolic pressure in human is 80 mm of Hg.

Thus, the correct answer is '120 mm of Hg.'

In adult, man normal BP is 

  1. 100/80 mm Hg

  2. 120/80 mm Hg

  3. 100/120 mm Hg

  4. 80/120 mm Hg
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Blood pressure is the pressure of the circulating blood against the walls of the arteries, the veins, and the chambers of the heart. The blood pressure in the large artery of the heart, the aorta, and the other large arteries of a healthy adult is usually 120 mm Hg during the contraction of the heart (systole), and 80 mm Hg during relaxation of the heart (diastole). Normal blood pressure is less than 120/80 mm Hg. So, the correct answer is-120/80 mm Hg.

In a normal man, blood pressure is

  1. 120/80mm of Hg

  2. 80/100 mm of Hg

  3. 80/120 mm of Hg

  4. 100/80 mm of Hg
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Blood pressure is defined as the pressure applied by the blood on the walls of arteries and veins during circulation. The instrument used is called a sphygmomanometer, and two variables are measured:
1. Systolic pressure, which occurs during heart muscle contraction, averages around 120 and is expressed in millimeters of mercury (mm Hg).
2. Diastolic pressure, which occurs during relaxation of the heart muscle, averages around 80 mm Hg.

So, the correct answer is option A.

The value of diastolic blood pressure is

  1. 120 mm Hg

  2. 80 mm Hg

  3. 120/80 mg Hg

  4. 40 mg Hg
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Hypertension is the term for blood pressure that is higher than normal (120/80). In this measurement, 120 mm Hg (millimeters of mercury pressure) is the systolic, or pumping pressure and 80 mm Hg is the diastolic, or resting, pressure.

So, the correct answer is option B.
