A patient is admitted to ED with low blood pressure and in circulatory shock. Which of the factors best explains the increase in Serum Lactate?

A. Her haemoglobin of 10g/dl

B. Her spO2 of 84%

C. Low cardiac index

D. Her arterial paCO2 of 60mmHg

Pharmacology A 70-year-old lady with atrial fibrillation secondary to ischemic heart disease was scheduled for laparoscopic umbilical hernia repair. She was induced with intravenous propofol, fentanyl and rocuronium. The surgery completed after 40 minutes. Her vitals are as follows, blood pressure 130/75 mmHg, heart rate is 90 beats per minute and Spo2 of 98%. She was given intravenous sugammadex prior to extubation.

Which of the following is the most likely explanation of your choice of reversal agent?

A. She is a geriatric patient

B. Sugammadex is a selective relaxant binding agent towards rocuronium

C. Patient has underlying atrial fibrillation

D. Sugammadex reduces the incidences of residual paralysis

1. 2 months old boy are scheduled for hernioplasty and circumcision. You are planning for gas induction for this boy.

Mask induction is accelerated in this patient compared to adults because of which of the following parameters?

A. Increased cerebral blood flow

B. Increased cardiac output

C. Increased tidal volume

D. Increased ratio of minute ventilation/functional residual capacity

2. 5 years old girl with right-to-left intracardiac shunt are scheduled for dental clearance prior to corrective cardiac surgery. The presence of the shunt results in which of the following?

A. Slows induction with soluble inhalational agents

B. Slows induction with insoluble inhalational agents

C. Speeds induction with insoluble inhalational agents

D. Speeds induction independent of the solubility of the inhalational agent

A 32-year-old second trimester pregnant lady came with Perforated Appendicitis had Laparoscopic Appendicectomy under general anaesthesia. Rapid sequence induction with IV suxamethonium was given. The surgery finished in 2 hours, however there was no spontaneous breathing noted despite no non-depolarizing muscle relaxant given.

What is the MOST likely reason that contributes to this patient's condition?

A. Hypothermia|

B. Patient used to be on oral contraceptive medication

C. Pregnancy at second trimester

D. Abnormal genetic variant

Answer D

A 17-year-old teenager undergoing corrective scoliosis surgery with neurophysiology monitoring using TIVA technique.

Why propofol is best used for the above technique?

A. It increases clearance of propofol when used with TCI remifentanil.

B. It has no active metabolites

C. It has anti-convulsant properties.

D. It causes increase in latency in somatosensory evoke potential.

Answer: B
