-
SARS
Jaundice is a yellowish pigmentation of the skin, the conjunctival membranes over the sclerae (whites of the eyes), and other mucous membranes caused by high blood bilirubin levels. This hyperbilirubinemia subsequently causes increased levels of bilirubin in the extracellular fluid. Concentration of bilirubin in blood plasma is normally below 1.2 mg/dL (<25µmol/L). A concentration higher than approx. 3 mg/dL (>50µmol/L) leads to jaundice.
Epidemic jaundice can occur in which of the following conditions?

Which of the following in the blood stream is reduced most by excessive vomiting and diarrhoea?
-
Calcium
-
Sodium
-
Potassium
-
Iron
Low blood sodium is also known as hyponatremia. Sodium is an electrolyte. It helps maintain the balance of water in and around your cells. Sodium is important for proper muscle and nerve function. It also keeps your blood pressure stable. Low blood sodium occurs when water and sodium are out of balance. Either there is too much water or too little sodium. Many factors can cause low blood sodium. Sodium levels may get too low if your body is losing too much water and electrolytes. It may also be a symptom of certain medical conditions. Causes of low sodium include: severe vomiting or diarrhea, taking certain medications, including antidepressants and pain medications, use of diuretics (water pills), drinking too much water during exercise (although this is very rare) etc. Calcium, potassium and iron are not reduced in blood stream by excessive vomiting and diarrhoea. Thus, option B is correct.

Jaundice occurs if there is a dysfunction of the normal metabolism or excretion of bilirubin. Common signs and symptoms seen in individuals with jaundice include: yellow discolouration of the skin, mucous membranes, and the whites of the eyes, light-coloured stools, dark-colored urine and itching of the skin. The underlying disease process may result in additional signs and symptoms. These may include: nausea and vomiting, abdominal pain, fever, weakness, loss of appetite, headache, confusion, swelling of the legs and abdomen, and newborn jaundice.
Diarrhoea is the ______ leading cause of death in children under five years old.
-
2nd
-
3rd
-
4th
-
5th
Diarrhoeal disease is the second leading cause of death in children under five years old, and is responsible for killing around 7,60,000 children every year. Diarrhoeal diseases caused by pathogenic bacteria and viruses are transmitted via the faecal-oral route. The pathogens discharged in the faeces of an infected person may enter the body of another susceptible person through the mouth. This may occur among children ingesting food or water contaminated with human excreta.
If your diet does not contain enough roughage, then you are likely to suffer from
-
Indigestion.
-
Constipation.
-
Diarrhea.
-
Typhoid.
Roughage or dietary fiber as it is known is the indigestible portion of the carbohydrate in the food derived from plants. These are of two types - the soluble fiber and and the insoluble one. The insoluble fiber is metabolically
inert and being prebiotic and ferment in the large intestine. These bulking fibers tends to absorb water as they move through the digestive system which helps in easy defecation. Hence, consuming a diet without roughage will lead to constipation.
If a person is adviced to intake ORS, it means he is suffering from
-
Typhoid
-
Jaundice
-
Diarrhoea
-
Measles
Oral rehydration therapy is a fluid replacement strategy used to prevent or treat dehydration. Dehydration is most commonly caused by diarrhoea. It involves drinking water with required amounts of sugar and salt added present in oral rehydration salts (ORS).
Jaundice is a disease of
-
Kidney
-
Liver
-
Pancreas
-
Duodenum
Jaundice refers to the yellow color of the skin and whites of the eyes caused by excess bilirubin in the blood. Bilirubin is a yellow pigment that is formed by the breakdown of dead red blood cells in the liver. Normally, the liver gets rid of bilirubin along with old red blood cells. Jaundice occurs when the liver does not break down bilirubin the way it is supposed to because the liver might be damaged and unable to perform this process.
Diarrhea can be caused by
-
Bacteria
-
Virus
-
Both A and B
-
None of the above
Diarrhea is a condition that’s characterized by the appearance of loose, watery stools or a frequent need to have a bowel movement. Diarrhea can be related to a viral or bacterial infection, or it can be the result of food poisoning. Rotavirus, norovirus and adenovirus are the common viruses which causes diarrhea. Campylobacter, Shigella are the common bacterias which causes diarrhea. Hence option C is correct.
Which among the following are the symptoms of diarrhoea?
-
Sunken eyes
-
Dehydration due to loose motions
-

Frequent diarrhoea can result in dehydration, sunken eyes, dry mouth and lips, abdominal pain, bleeding from rectum etc. Hence option D is the correct answer.
Preventive measures of constipation is
-
High fibre diet
-
Vaccination
-
Antacids
-
None of the above
Dietary fiber is the indigestible portion of the carbohydrate in the food derived from plants. These are of two types - the soluble fiber and the insoluble one. The insoluble fiber is metabolically inert and being prebiotic and ferment in the large intestine. These bulking fibers tend to absorb water as they move through the digestive system which helps in easy defecation. Hence, consuming a diet with high fiber content will help prevent constipation.

Which of the following can be useful to avoid digestive problems?
-
Balanced diet
-
Drinking plenty of water
-
Thoroughly masticating food
-
All of the above
Digestion is the process in which the food gets digested and broken down into smaller components which are absorbed by the cells of the body. If the process of digestion is not carried out properly, it might lead to bowel problems like constipation. There should be a balanced diet which includes fibers. Plenty of water should be taken which will prevent the problems like constipation and acidity. The food should be properly masticated before swallowing because the basic digestion starts in the mouth.
A person is not suffering from indigestion. This can be analyzed as
-
Balanced diet is not taken.
-
Taking diet in hurry.
-
Thoroughly chewing the food.
-
Doing exercise after meal.
Indigestion is the problem when the food is not digested properly. This may occur due to the acid in the stomach, exercise after meals, diet is taken in hurry, the food contains excess fat or the food is not chewed properly. When the person has taken a balanced diet which contains fibres, proteins, sugars, vitamins, then there are fewer chances that the person will suffer from the problems of indigestion. When the food is chewed properly, the food gets properly digested.
Identify the symptoms of indigestion.
-
Fever
-
Bloating
-
Growling stomach
-
Both B and C
Digestion is the process in which the food gets digested and broken down into smaller components which are absorbed by the cells of the body. If the process if digestion is not carried out properly might lead to bowel problems like constipation. There is production of acid and gas in the stomach, which results in problems like bloating. There is movement of the gas in the stomach which is described as growling stomach. This may also be associated with pain in the stomach.
When the peristaltic movements of the stomach and oesophagus reverse their normal direction, it causes
-
Constipation
-
Indigestion
-
Vomiting
-
Acidity
Peristalsis pushes food through the lower oesophagus into the stomach. When the peristaltic movements of the stomach and oesophagus reverse their normal direction, it is called reverse peristalsis. In this situation, the contraction of abdominal muscles and diaphragm pushes food back through the oesophagus and out through mouth which results to vomiting. So, the correct option is C.

Jaundice is a disease which causes yellowing of skin and eyes which occurs due to the presence of the excess of pigment bilirubin. Pigment bilirubin is formed in the body as a result of the breakdown of worn out RBCs in the liver and is regularly excreted through kidneys. Jaundice occurs if the liver is not able to metabolize bilirubin and is caused by the virus. It can also lead to inflamed liver or obstructed bile duct. Too much bilirubin can leak into the tissues and causes yellowing of skin and eyes.

Consider the statements.
A. 'Oral Rehydration Solution' (ORS) should be given to cholera or diarrhoea patients at regular intervals.
B. Poliovirus is transmitted through food or water and ultimately affect central nervous system.
C. E.coli and Shigella bacteria are responsible for diarrhoea disease.
D. Rhinoviruses are responsible for common cold.
The correct statements are
-
A and D
-
A and B
-
A, C and D
-
All of the above
Rehydration can be accomplished using solutions with higher sodium, i.e., 75-90 mmol/L. These are termed rehydration solutions (ORS). High sodium rehydrating solutions used to treat acute dehydration may be used for maintenance by giving the solution alternately on a 1-to-1 basis with a no-sodium or low-sodium fluid such as water or breast milk. Poliovirus is usually spread from person to person through infected faeces entering the mouth. It may also be spread by food or water containing human faeces and ultimately reaches the central nervous system (CNS). Virulent Escherichia coli strains cause either non inflammatory diarrhoea (watery diarrhoea) or inflammatory diarrhoea (dysentery with stools usually containing blood, mucus and leukocytes). Shigella is one of the leading bacterial causes of diarrhoea worldwide. The characteristic clinical syndrome associated with rhinovirus infection is the common cold.
Two communicable diseases prevalent in developing countries caused by unsafe drinking water and bad sanitation are
-
Acute diarrhoea and cancer
-
Diarrhoea and schistosomiasis
-
Onchocerciasis and leukaemia
-
Rheumatism and malaria
Schistosomiasis infection is acquired when people come into contact with fresh water infested with the larval forms of parasitic blood flukes, known as schistosomes. The microscopic adult worms live in the veins draining the urinary tract and intestines. Eggs from the mature worms are passed out (excreted) in the faeces or urine of an infected person. These eggs can get into fresh water if it is contaminated with human sewage. Symptoms can be bloody diarrhoea, abdominal pain, right upper quadrant pain, cramps.
Haemolytic jaundice is caused by a dominant gene but only 10% of the people actually develop it. What proportion of the children would be expected to develop the disease, if a heterozygous man marries a homozygous normal woman?
-
1/5
-
1/10
-
1/15
-
1/20
Genotype of the man --> A$^H$A (where A$^H$ is the chromosome carrying dominant gene for haemolytic jaundice and A is the homologous chromosome carrying the normal allele).
Genotype of woman --> AA
P generation : A$^H$A X AA
F$ _1$ generation : A$^H$A A$^H$A AA AA
(Diseased:Normal) = (1:1)
Only 10% of the people having diseased genotype actually suffer from haemolytic jaundice, this turns the ratio to (0.1:1).
Thus, proportion of children expected to develop the disease for the given cross= 0.1/2 (0.1 children are affected out of two children) = 1/20
Dry heaven is
-
Episodes of motion
-
Episodes of vomiting
-
Episodes of urination

Episodes of acidity
Vomiting is considered as the uncontrolled form of reflex action. During this response, the contents of the stomach are thrown in the upward direction and removed from the mouth. The contents of the stomach and water are lost during this process. This leads to drying of the tissues of the alimentary canal. This is called as dry heaven. This condition is observed when there are continuous episodes of vomiting.
