Question71:-A 55 kg 81-year-old man suffers an acute myocardial infarction. Following coronary artery bypass grafting he is admitted to the cardiac intensive care unit. He is intubated
‘and ventilated with no inotropic or vasopressor support. Cardiac output studies show: heart rate 115 bpm, blood pressure is 131/78 mmHg, central venous pressure 19 mmHg, cardiac
index 1.9 Limin/m® , pulmonary artery wedge pressure 24 mmHg and systemic vascular resistance index 2800 dyne/s/em” m*. His urine outputis less than 20 mihour, and his lactate
is 6.1 mmolL. There is no evidence of tamponade on echocardiogram. The most appropriate medication would be

1

B:-Dobutamine

C:-Noradrenaline

D:-Digoxin

Correct Answer:- Option-é

ध 57-year-old male is undergoing coronary artery bypass grafting (left internal mammary artery to left anterior descending artery). After termination of Cardiopulmonary
Bypass (CPB), you notice a prominent V wave in the Pulmonary Artery Occlusion Pressure (PAOP) tracing. The most likely reason for the finding is

‘AcLeft-ventricular dysfunction
B:-Right-ventricular dysfunction
Cardiac tamponade
D:-Posterior papillary muscle dysfunction
Correct Answer:- Option-D
Question73:-In which of the following situations is applying Continuous Positive-Airway Pressure (CPAP) to the nondependent lung most ideal for improving oxygenation ?
‘AcBronchopleural fistula
B:-Open lobectomy
ட pulmonary hemorthage
D-Sleeve resection
Correct Answer:- Option ®
Question74:-Crtical lines Polyneuropathy (CIP)
‘Ac Characteristically involves the cranial nerves

D-Can be treated with highdose steroids
Correct Answer:- Option ®
Question75:-According to SHEA/IDSA Practice Recommendation 2014, the general strategies to reduce VAP include all except
‘A: Prefer nasal intubations to oral unless contraindicated
B:-Routine change of ventilator circuits is not required unless visibly soiled or malfunctioning

ണി: endotracheal tube cuff pressure (keep it between 20-30 cmi/,0) to avoid air leaks around the cuff, which can allow entry of bacterial pathogens into the lower
respiratory tract, while permitting capillary perfusion

D:-Prefer endotracheal tubes with a subglottic suction port to prevent pooling of secretions around the cuff leading to microaspiration for patients expected to require greater than
48 or 72 hours of mechanical ventilation

Correct Answer:- Option-é

D-Severe metabolic acidosis (pH < 7.1)
Correct Answer:- Option-é
