General Anaesthetics1. Propofola. Accumulates <=b. Can produce abnormal muscle movements <= after prolonged usec. Has minimal effect on the cardiovascular systemd. ?e. ?2. Propofol:a. Is less painful when injected than thiopentoneb. Causes less hypotension than thiopentonec. Is less likely to cause post operative vomiting than thiopentoned. Causes cumulative effects when given as a continuous infusion -? It does, delayed arousale. Is useful in long term sedation in ICU for periods of 1-2 weeks <=3. Ketamine:a. Is useful as an induction agent in head injured patientsb. Decreases salivationc. Decreases heart rate and may cause bronchoconstrictiond. Must be given intramuscularlye. May cause unpleasant dreams in children <=4. Regarding inhaled anaesthetics, which is NOT true?a. The depth of anaesthesia is related to the alveolar concentration of the gasb. The potency of these agents is directly proportional to their fat solubilityc. The alveolar concentration is not influenced by cardiac outputd. Nitrous oxide when administered alone cannot produce surgical anaesthesiae. More than 95% of halothane is excreted by the lungs <=5. Propofol:a. Is mainly excreted unchanged in urineb. Has minimal effects on blood pressure during inductionc. Has a recovery rate from anaesthesia similar to the barbiturates - fasterd. Has antiemetic properties <=e. Hypersensitivity reactions are due to the intralipid component <= true? Also used for LA tox6. Ketamine is closely chemically related toa. Phencyclidine <=b. LSDc. Propofold. Thiopentonee. Enflurane7. The MAC (minimum alveolar concentration) is greatest for:a. Nitrous oxide <= 100%b. Halothanec. Isofluraned. Methoxyfluranee. Ketamine8. All of the following are anaesthetic agents EXCEPT:a. Midazolamb. Glycopyrrolate <=c. Propofold. Fentanyle. Etomidate9. Regarding intravenous anaesthetics:a. Ketamine is a cardiovascular depressantb. Respiratory depression is rare following use of midazolamc. Delayed recovery is expected following prolonged infusion of propofol = ???d. Barbiturate anaesthetics have a rapid onset of action due to high lipid solubility <=e. Intravenous opioids aid chest wall relaxation10. Regarding adverse effects of propofol:a. Post-operative vomiting is commonb. Hypertension is a complicationc. Severe acidosis can occur with its use in paediatric respiratory infection <=d. It is positively inotropice. Tremors are a common side effect ................
