1. How is dengue detected in blood?
a) Low level of RBCs
b) Low level of WBCs
c) Low level of Platelets
d) Low level of fibrin
Explanation: While dengue expresses itself in the form of fever, the sure test for dengue is the reduction in the number of platelets. The loss of platelets reduces the blood clotting capacity. When a person suffers from external injury the bleeding does not stop easily. When there is a severe reduction of platelets, the person may suffer from internal bleeding and die.
2. What machine is used to test the blood?
a) Auto analyzer
b) Hemodialyzer
c) Diathermy machine
d) Ventilator
Explanation: An auto analyzer has various tests and processes of doing those tests fed into it. It can do a test for over hundred samples using minimum amounts of blood within a span of few hours. Thus, an auto analyzer is currently the most favorite machine to do the various tests regarding blood.
3. What is the normal haemoglobin content of the RBCs?
a) 0.3pgm
b) 3.0pgm
c) 30pgm
d) 300pgm
Explanation: Haemoglobin is the protein that is responsible for the transport of oxygen and carbon-dioxide from the lungs to the cells in the body. Haemoglobin is carried by the RBCs and every RBC has 30pgm of haemoglobin.
4. Anaemia is caused due to deficiency of _________
a) Haemoglobin
b) Fibrin
c)Thrombin
d) Neutrophils
Explanation: An important component of haemoglobin is iron. When the quantity of iron goes down in body, it causes the haemoglobin content of the body to go down. Anemia symptoms include fatigue, dizziness, shortness of breath etc.
5. Hemophilia is more dominant in _________
a) Males
b) Females
c) Young children
d) Transvestite
Explanation: Haemophilia is a genetic problem in which the X chromosome is the carrier of the mutated gene. If a person is suffering from hemophilia, their blood has lost the ability to clot or the blood clotting ability has gone down. Since men have one X and one Y chromosome, they are more susceptible to get hemophilia.
6. A virus that destroys the immunity of the body and can spread through blood is __________
a) HIV
b) Gonorrhea
c) Anemia
d) Hemophilia
Explanation: HIV stands for Human Immunodeficiency Virus. HIV attacks the immune system of the body and causes AIDS (acquired immunodeficiency syndrome). A common method for HIV to propagate is through the transfusion of blood. It can stay hidden for long periods of time and can be discovered much later after it has attacked.
7. The number of cartilagineous structures in a long bone are ____________
a) 2
b) 5
c) 0
d) 1
Explanation: Each long bone has articular/hyaline cartilage at the outer extremities of the bone and an epiphysial cartilage at the extremities of the shaft. Hyaline Cartilage helps reduce friction and the epiphysial cartilage helps the bone grow. At maturity, the epiphysial cartilage of the bone solidifies.
8. The reason why people have joint pain in old age is because _____________
a) the bones become weak
b) the bones become too strong
c) the chondrocytes in articular cartilage become lesser in number
d) the blood supply to the joints reduces
Explanation: Articular cartilage is the cartilage at the lining of the extremities of the long bones. It helps reduce friction and has chondrocytes. It has no blood supply and takes and nourishment from the synovial fluid. Drying of the synovial fluid and loss of chondrocytes causes pain in the joints
9. Ellipsoid joint is found at __________
a) atlanto-occipital joint
b) first carpo-metacarple joint
c) first tarso-metatarsle joint
d) atlando-axial joint.
Explanation: The elipsoid joint can perform functions like forward, backward and sliding movement. Atlanto-occipital joint is the joint between the 1st vertebra and the skull. Atlandto-axial joint is the joint of 1st and 2nd vertebrae. 1st carpo-metacarple joint and 1st tarso-metatarsle joints are the joints of the thumb and big toe.
10. Which of these is a multi-axial joint?
a) elbow joint
b) ball and Socket joint
c) shoulder joint
d) thumb joint
Explanation: The term multiaxial joint stands for the joint which can move in all axis. Ball and socket joint can perform functions like an extension, flexion, abduction, aduction, rotation, circumduction, i.e., all possible movements. Thus, it’s multiaxial.
