Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Rabies is a viral disease that causes inflammation of the brain in humans and other mammals. Early symptoms can include fever and tingling at the site of exposure. These symptoms are followed by one or more of the following symptoms: violent movements, uncontrolled excitement, fear of water, an inability to move parts of the body, confusion, and loss of consciousness. Once symptoms appear, the result is nearly always death. The time period between contracting the disease and the start of symptoms is usually one to three months, but can vary from less than one week to more than one year. The time depends on the distance the virus must travel along peripheral nerves to reach the central nervous system.

So the correct option is 'virus and it affects the nervous system'.

Which of the following are the symptoms of cholera?

  1. Diarrhea

  2. Nausea

  3. Dehydration

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

Most people exposed to the cholera bacterium (Vibrio cholerae) do not become ill and never know they've been infected. Yet, because they shed cholera bacteria in their stool for seven to 14 days, they can still infect others through contaminated water. Most symptomatic cases of cholera cause mild or moderate diarrhea that's often hard to distinguish from diarrhea caused by other problems. Symptoms of cholera infection may include diarrhea, nausea and vomiting, dehydration.

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.
  4. ${CI^-}$ ions is significant component of blood plasma.

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
Reveal answer Fill a bubble to check yourself
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.
