The cells related to blood are collectively called as(a) oestoblast cells(b) concdrocyte cells(c) hematopoietic cells(d) megakaryocytes |
|
Answer» Right choice is (c) hematopoietic cells The explanation: Hemato is a term that related to blood. All the cellular components of the blood originate from the hematopoietic cells. They are found in the bone marrow of the long bones and are self renewing in nature. These are also considered as stem cells as they can give rise to different types of cells. |

What machine is used to test the blood?(a) Auto analyzer(b) Hemodialyzer(c) Diathermy machine(d) Ventilator |
|
Answer» Right answer is (a) Auto analyzer The best 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. |

The operation which allows air to be given directly in the trachea is called ________(a) Tracheotomy(b) Vasectomy(c) Disc Prolapse(d) Clog Removing |
|
Answer» Right answer is (a) Tracheotomy To explain: Tracheotomy is a process in which an incision is made on the throat and the respiratory passage is accessed. A tube is directly inserted in the passage and the ventilator is used to send air into the tube. Thus, the air is given directly in the trachea and lungs. This happens in very severe cases when the person is not able to breathe by themselves. |

What all modes exist in ventilator?(a) Neonatal mode, normal mode(b) Normal mode, geriatric mode(c) Neonatal mode, normal mode, geriatric mode(d) Neonatal mode, pediatric mode, normal mode, geriatric mode |
|
Answer» Right option is (a) Neonatal mode, normal mode To elaborate: A neonate has very delicate lungs so they need special care during ventilation. Thus, they have a separate mode. In modern ventilators, there is separate kind of ventilators, especially for the neonates. All the other population is kept on the normal mode. |

How many blood types exist including the positive and negative factors?(a) 3(b) 4(c) 8(d) 6 |
|
Answer» The correct answer is (c) 8 To explain I would say: Blood is classified into two factors, antigen-antibody and rhesus factor. There are two types of antigens A and B. The cells having antigen A have antibody B while those having antigen B have antibody A. This makes the blood group A and B. AB blood group have both antigens A and B and no antibodies. Blood group has no antigens but antibodies for both. This makes four blood groups A, B, AB, O. The presence and absence of Rh factor make these four blood groups into 8. A+, A-, B+, B-, AB+, AB-, O+ and O-. |

After surgery, an incentive spirometer is used to prevent _________(a) Lung collapse(b) Gastric and intestinal problems(c) Elevated blood pressure(d) Blood Clotting |
|
Answer» Correct choice is (a) Lung collapse The best explanation: A spirometer is used to help the lungs regain their strength. After a surgery, due to the use of the ventilator, the lungs may feel a little abnormal and may have a weakness. This is also possible due to age. The person is made to breathe into the spirometer to exercise their lungs and regain normal lung function. Normally, 10 to 15 breaths with the spirometer every 1 to 2 hours is prescribed, or as often as instructed by your nurse or doctor. |

Before reaching the operation theater, how many zones exist?(a) 1(b) 3(c) 5(d) 7 |
|
Answer» The correct answer is (b) 3 Easy explanation: Before entering an OT, normally there will be three zones. The outermost zone is a waiting zone, until where the patient may be accompanied by a family member. Here is also a nursing management station where the nurses and doctors go through the final paperwork for operation. The next zone is the changing zone. The changing rooms are right next to the entry so that the doctors, nurses, and technicians can immediately change into their OT scrubs. Even the shoes need to have a covering or normally they have different pairs of shoes and slippers in the changing room. Beyond that is the anesthesia room where the vitals are monitored for one last time and anesthesia is administered. Finally comes the operation theater. Within the zones, there are often resting chambers for the OT staff, offices of the surgeons, pharmacy and supply door to C.S.S.D. |
|
| 8. |
How are the OT ventilated?(a) Air is blown in from the lower part of the wall(b) Air is sucked out from the upper region of the wall(c) Air is blown in from the lower part and sucked out from the upper part(d) Air is blown in from the upper part and sucked out from the lower part |
|
Answer» Right choice is (d) Air is blown in from the upper part and sucked out from the lower part For explanation: This kind of ventilation system should actually exist throughout the hospital. The air which passes through various filters is pumped in and the air in the room is pulled out from the lower regions. This forms a steady air current and fresh, treated air is constantly circulated. This reduces the chances of nosocomial infections and wound festering. |
|
| 9. |
The first anesthesia used was ___________(a) polyvinyl chloride(b) trichloro methane(c) chlorofluorocarbon(d) tetra fluorocarbon |
|
Answer» Right option is (b) trichloro methane To elaborate: Trichloro Methane, more popularly known as chloroform was the first known and widely used anesthetic. It was used to numb the area, or inhaled as general anesthesia. It was used as a pain reliever and an anesthetic. However, it was found harmful for the kidneys. |
