Heat stroke is primarily caused by

  1. Excessive heat production

  2. The inability to sweat

  3. Conductive heat gain

  4. Inability to lose heat by radiation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Heat stroke is caused by the overheating of the body due to prolonged exposure to high temperature. Heat is exchanged with the environment in four ways such as conduction, convection, radiation, and evaporation. Conduction refers to heat loss through direct contact with a cooler object. Convection is the dissipation of heat when relatively cool air passes over exposed skin. Radiation is the release of heat from the body directly into the environment. Evaporation through perspiration is the body’s most effective method of cooling under most circumstances. 
Therefore, the correct answer is option D.

Which part of the human body is first adversely affected by nuclear radiation?

  1. Eyes

  2. Lungs

  3. Skin

  4. Bone marrow
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
On exposure to radiation burns the skin first and then other biological tissue. The radiation can be ultraviolet light and ionizing radiation that causes sunburn. High exposure to X-rays during diagnostic medical imaging or radiotherapy can also result in radiation burns. As the ionizing radiation interacts with cells within the body damaging them, the body responds to this damage, resulting in erythema i.e., redness around the damaged area. Radiation burns are often associated with radiation-induced cancer due to the ability of ionizing radiation to interact with and damage DNA, occasionally inducing a cell to become cancerous.
Therefore, the correct answer is option C.

Foot and mouth disease is a highly contagious disease almost exclusive to cattle, sheep, swine, goats, and other cloven-hoofed animals. It is caused by a

  1. Fungi

  2. Bacteria

  3. Protozoa

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

Foot-and-mouth disease or hoof-and-mouth disease is an infectious and sometimes fatal viral disease that affects cloven-hoofed animals, including domestic and wild bovine. The virus causes a high fever for two or three days, followed by blisters inside the mouth and on the feet that may rupture.

Therefore, the correct answer is option D.

Name the condition when the concentration of ketone body increases in urine.

  1. Acromegaly

  2. Diabetes mellitus

  3. Diabetes insipidus

  4. Cushing's disease
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Acidosis is due to rapid fat catabolism. This leads to high levels of acetoacetic acid, which is converted to acetone and beta-hydroxybutyric acid. These three molecules known as ketone bodies. The presence of excreted ketone bodies in urine and in expired air is used as one diagnostic test for diabetes mellitus. Thus, the correct answer is option B.

D Correct answer
Explanation

Explanation: Non-communicable disease (NCD) is a medical condition or disease that is noninfectious or non-transmissible. NCDs can refer to chronic diseases which last for long periods of time and progress slowly.

  3. Skin Cancer

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

Explanation: Communicable diseases are caused by pathogens passed from one human to another. Pathogenic organisms are of five main types: viruses, bacteria, fungi, protozoa, and worms. Whereas, most skin cancers are caused by exposure to the sun.
