In which of the following disease, yellow pigmentation of skin is seen?

  1. Jaundice

  2. Chickenpox

  3. Plague

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

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.

Jaundice is often seen in liver disease such as hepatitis or liver cancer. It may also indicate leptospirosis or obstruction of the biliary tract, for example by gallstones or pancreatic cancer, or less commonly be congenital in origin.

Which of the following in the blood stream is reduced most by excessive vomiting and diarrhoea?

  1. Calcium

  2. Sodium

  3. Potassium

  4. Iron
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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.
