Anaesthesia & Critical Care

20 learning units • 100 chapter sections • 200 explained questions. Prepare patients for anaesthesia, recognise perioperative emergencies and understand organ support, critical-care teamwork and recovery.

Original RAHBAR study material for the Year 5 learning pathway. Clinical cases support supervised undergraduate learning. Treatment choices, doses and procedures must follow current local protocols and the responsible clinical team. References & further reading ↓

Question 01. What contributes to tissue oxygen delivery? A. Cardiac output and arterial oxygen contentB. Saturation aloneC. Respiratory rate aloneD. Inspired oxygen setting alone

Question 02. Can severe anaemia impair oxygen delivery despite normal saturation? A. YesB. NoC. Only after paralysisD. Only with fever

Question 03. Which process most directly affects carbon dioxide elimination? A. Skin pigmentationB. Alveolar ventilationC. Urine colourD. Platelet count

Question 04. Can supplemental oxygen mask hypoventilation on pulse oximetry initially? A. NoB. Only in childrenC. YesD. Only if blood pressure is high

Question 05. Why can frailty or hypovolaemia alter anaesthetic drug response? A. Physiological reserve and drug sensitivity can changeB. They make all drugs ineffectiveC. They eliminate respiratory effectsD. They justify an identical fixed dose

Question 06. Do neuromuscular blockers provide unconsciousness? A. YesB. Only at low dosesC. Only during surgeryD. No

Question 07. What must accompany neuromuscular blockade? A. Observation of movement aloneB. No airway planC. Only a pain scoreD. Ventilation, anaesthesia and recovery monitoring

Question 08. Does absence of movement prove adequate anaesthesia? A. NoB. YesC. Only if paralysis is usedD. Only in a short procedure

Question 09. What can prolong drug effects after a procedure? A. Only the procedure nameB. Repeated doses or impaired clearanceC. Normal skin colourD. A signed consent form

Question 10. Does reversal eliminate the need for continued monitoring? A. YesB. NoC. Only after extubationD. Only in day surgery
