Cholera patient is administered by 'saline drip' because

  1. ${Na^+}$ ions are essential for the transport of substances across the membrane.
  2. ${Na^+}$ ions are helpful to conserving water in the body.
  3. ${CI^-}$ ions are helpful in the formation HCl for digestion.

B Correct answer
Explanation

Cholera is the infection of the small intestine and is caused by the bacterium, Vibrio cholerae. The hallmark of the disease is profuse secretory diarrhoea. So, the patients with cholera are administered by saline drip or NaCl as the sodium ions or Na ions helps in retaining the water.
Therefore, the correct answer is option B.

Saline drip is given to a Cholera patient because

  1. NACI kills Vibrio cholera

  2. NACI generates ATP
  3. Na$^+$ ions stops nerve impulse and hence sensation of pain
  4. Na$^+$ ions help in retention of water in body tissue

D Correct answer
Explanation

Patients suffering from cholera are given a saline drip because Na+ ions help in the retention of water in the body tissues. Severe diarrhea, vomiting, watery stools are the chief symptoms of cholera. All these lead to dehydration. Actually, cholera toxin secreted by Vibrio cholerae causes, through a series of metabolic reactions, the continuous activation of adenylate cyclase of intestinal epithelial cells. The resultant high concentration of c-AMP triggers continuous secretion of chlorine, bicarbonate, and water into the lumen of the intestine. Administration of saline not only supports the sodium-potassium pump through which water in the cell is restored, but glucose is also imported along with sodium. Thus, the correct answer is option D.

Water contaminated with Vibrio cholerae can be made potable

  1. By boiling alone

  2. By passing through filter

  3. By treating with chloride

  4. By freezing the water

A Correct answer
Explanation

Cholera is an intestinal infection caused by eating and drinking contaminated food and water with the Vibrio cholerae. It is characterized by diarrhea and dehydration. This infection can ve prevented by the use of boiled water, cook food well and keep it covered and maintaining personal and public hygiene. Thus, the correct answer is option A.

Acute diarrhoea and dehydration are the symptoms of 

  1. Leprosy

  2. Tetanus

  3. Tuberculosis

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

Cholera is caused by a bacterium called Vibrio cholerae. A person gets cholera by drinking water or eating food infected with the bacterium. Once swallowed, it settles in the lining of the small bowel and releases a toxin (poison) that can cause the body to flush liquid into the small bowel, resulting in watery diarrhoea. The main symptom is watery diarrhoea, which can be severe enough to rapidly drain the body of vital water, salts and minerals. The first watery stool appears 1 to 3 days after infection, and from then on the body can lose up to one litre of liquid an hour.

B Correct answer
Explanation

Sir Ronald Ross discovered the malarial parasite in the gastrointestinal tract of mosquito and led to the realization, that malaria was transmitted by mosquitoes. He received the Nobel Prize in 1902 for his work on malaria.

Treatment of cholera includes _________

  1. Oral rehydration solution

  2. Antibiotics

  3. Zinc supplementation

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

The primary treatment is oral rehydration therapy - the replacement of fluids with slightly sweet and salty solutions rice-based solutions are preferred. Zinc supplementation is useful in children. In severe cases, intravenous fluids, such as Ringer's lactate, may be required, and antibiotics may be beneficial.

A person is suffering from muscle cramps, vomiting, acute diarrhoea, dehydration and passage of rice water like stool. Which of these diseases has the maximum possibility to occur?

  1. Diptheria

  2. Tuberculosis

  3. Cholera

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

Vibrio cholerae is the bacterium which is responsible for the disease cholera. This is a disease which is transmitted due to contaminated water with feces containing the bacteria. The symptoms of the disease are frequent muscular cramps due to loss of electrolytes in acute diarrhea, vomiting, dehydration, passage of watery stools, etc.

Thus, the correct answer is option C.

D Correct answer
Explanation
Vibrio cholerae is the causative agent of cholera. The disease is characterized by the loss of excess water from the body leading to a condition called profuse secretory diarrhea. Giving saline drip or NaCl helps in helps in the retention of water by the body. Thus the correct answer is option B.

Ronald Ross discovered female Anopheles to be vector of malaria while serving in

  1. Chennai

  2. Kolkata

  3. Pune

  4. Bangalore
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Sir Ronald Ross made his first major breakthrough in the study of malaria while working in Secunderabad. It was there that he raised 20 mosquitoes in 1897 and let them feed on a (paid) malaria patient’s blood. On August 20th—now commemorated as World Mosquito Day—Ross discovered the malarial parasite in the stomach of one of his mosquitoes. The next day, he confirmed that it was growing. It was in Kolkata the next year, at the Presidency General Hospital (now the SSKM Hospital), that Ross confirmed how the parasite spread. Using bird subjects to study avian malaria, he found that after developing in the stomachs of mosquitoes, the parasite would move to the salivary gland, from which it would infect new hosts.

So, the correct answer is 'Kolkata'.
