How Intra Aortic Balloon Counter Pulsation (IABP) is protective for myocardium ?

Increases preload

Reduces contractility

Improves coronary perfusion and reduces afterload

Increases afterload

Correct! Wrong!

Intra-aortic balloon counterpulsation simultaneously increases coronary blood flow, by augmentation of the diastolic aorto-coronary pressure gradient, and decreases myocardial oxygen demand, by reducing the end-diastolic pressure, and, therefore, the after-load.

How long smoking should be discontinued before elective surgeries to reduce peri operative pulmonary complications ?

1 – 2 weeks

6 – 8 weeks

2 – 3 weeks

10 – 12 weeks

Correct! Wrong!

In current practice, smoking cessation of 6-8 weeks before an elective surgery has been recommended to reduce perioperative pulmonary complications.

Which is the most commonly used double lumen bronchial tube nowadays ?

Combitube

Carlen's

White

Robert-Shaw

Correct! Wrong!

Cerebral blood flow remains nearly constant between Mean Arterial Pressure of

10 – 100 mmHg

100 – 200 mmHg

60 – 160 mmHg

160 – 260 mmHg

Correct! Wrong!

Venous air embolism during neurosurgery can occur when

Blood pressure is high

Partial pressure of carbon dioxide is high

The wound is below the level of heart

The pressure within the open vein is sub-atmospheric

Correct! Wrong!

Rate of correction of sodium in severe hyponatraemia is

0.5 – 1 mEq/L/hour and not more than 10 mEq/L/Day

1 – 2 mEq/L/hour and not more than 18 mEq/L/Day

1 mEq/L/Day

20 mEq/L maximum in a day irrespective of rate of infusion

Correct! Wrong!

Which is the most important buffer system in Extra cellular fluid compartment ?

Phosphate – Phosphoric acid

Oxidised haemoglobin – reduced haemoglobin

Proteins

Bicarbonate – Carbonic acid

Correct! Wrong!

Lithotomy position is required for all of the following except

Assisted Conception

Laparoscopic tubectomy

Endometrial tubal ligation

Cervical Biopsy

Correct! Wrong!

All of the following agents should be avoided in a patient with Malignant Hyperthermia except

Sevoflurane

Isoflurane

Succinylcholine

Vecuronium

Correct! Wrong!

The following is the process that kills spores

Disinfection

Sterilization

Decontamination

Sanitize

Correct! Wrong!

The PIN safety system is designed for which purpose ?

To prevent the gas hose from one gas to be connected to another

To prevent the backflow of gases from one cylinder to another

The prevent the placement of gas tanks onto the wrong yolk

To allow the quick connection/release of gas hose to the machine

Correct! Wrong!

The Piped gas pressure should be

20-25 psig

30-35 psig

40-45 psig

50-55 psig

Correct! Wrong!

All of the following are characteristics of modern day vaporizers except

Agent specific

Variable bypass

Temperature compensated

In circuit

Correct! Wrong!

An effective anesthesia breathing system has

Large reservoir

Low resistance

Low dead space

All of the above

Correct! Wrong!

Which of the following is NOT indicative of an exhausted CO2 absorbent ?

Change in color of the granules

Increase in temperature of the granules

Moisture in the circuit

Increased inspired CO2

Correct! Wrong!

Which of the following ventilator modes requires patient to initiate a respiratory cycle ?

Volume Control

Pressure Support

Pressure Control

PEEP Mode

Correct! Wrong!

Function of PEEP is

It prevents alveolar collapse hence improves Oxygenation

It prevents backflow of ventilator gases through vaporizer

It prevents breathing circuit gases through the CO2 absorber

Increases the airway resistance and decreases pulmonary compliance

Correct! Wrong!

A leak in oxygen flow tube may be identified with the help of

Positive pressure leak test

Oxygen Analyzer

Negative pressure leak test

All of the above

Correct! Wrong!
