A nurse measures the blood pressure of a seated patient to be $190$ mm of Hg.

  1. the blood pressure at the patient's feet is less than $190$ mm of Hg.
  2. the actual pressure is about $0.25$ times the atmospheric pressure.
  3. the blood pressure at the patient's neck is more than $190$ mm of Hg.
  4. the actual pressure is about $1.25$ times the atmospheric pressure.

  1. $9-12$
  2. $15-18$
  3. $21-24$
  4. $30-33$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Breathing (or ventilation) is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly by bringing in oxygen and flushing out carbon dioxide.
  • The Normal range of breathing rate per minute in an average adult person at rest is 15-18.
  • So, the correct answer is '15-18'.

Multiple choice biology body fluids and circulation cardiac disorders cardiac regulation and disorders the blood system

What is correct regarding blood pressure?

  1. 105/50 mm Hg makes one very active

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

  3. 190/110 mm Hg may harm vital organs like brain and kidneys

  4. 130/90 mm Hg is considered as high and requires treatment
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Blood pressure 190/110 mm Hg indicates high blood pressure or hypertension. Normal systolic and diastolic blood pressure in body is 140 mm Hg and 90 mm Hg respectively. Pressure above 140 mm Hg and 90 mm Hg is high blood pressure which can cause damage to vital organs like brain and kidney. High blood pressure can cause damage to blood vessels in brain and kidney. This can lead to rupture of blood vessels and cause brain haemorrhage. In kidneys, high blood pressure can lead to inadequate supply of blood to kidney and thus, resulting in decreased filtration.
So, the correct answer is '190/110 mm Hg may harm vital organs like brain and kidneys'.
