(b) Nitrous oxide
(c) Halothane
(d) Isoflurane
111. Select the correct statement about nitrous oxide:
(a) It irritates the respiratory mucosa
(b) It has poor analgesic action
(c) It is primarily used as a carrier and adjuvant to other
anaesthetics
Anaesthesia
(d) It frequently induces post anaesthetic nausea and
retching
112. Ether is still used as a general anaesthetic in India,
specially in peripheral hospitals because:
(a) It is non-explosive
(b) It is pleasant smelling and non irritating
(c) It induces anaesthesia rapidly
(d) It is cheap and can be administered without anaesthetic
machine
113. As a general anaesthetic, halothane has the following
advantages EXCEPT:
(a) Very good analgesic action
(b) Non-inflammable and non-explosive
(c) Reasonably rapid induction of anaesthesia

116. Ketamine is the preferred anaesthetic for the following
EXCEPT:
(a) Hypertensives
(b) Trauma cases that have bled significantly
(c) Burn dressing
(d) Short operations on asthmatics
117. If ketamine is the only agent used in reducing a
dislocated shoulder, its actions will include:
(a) Analgesia
(b) Bradycardia
(c) Hypotension
