The drug which can be used to numb pain sensation during minor operation like wound stitching is:
A)
Lignocaine
B)
Bupivacaine
C)
Oxetacaine
D)
Adrenaline
Lignocaine (lidocaine) is a local anaesthetic commonly used to numb a small area of skin or tissue during minor procedures such as wound stitching. Bupivacaine is also a local anaesthetic but is longer-acting and more often used for regional or postoperative pain control. Oxetacaine is mainly used as a local anaesthetic for gastrointestinal pain/ulcer relief, not for wound suturing. Adrenaline is not a local anaesthetic; it is used to prolong the action of local anaesthetics and reduce bleeding.

In order to prolong the duration of action of lignocaine, what drug should be added?
A)
Adrenaline
B)
Dopamine
C)
Isoprenaline
D)
Propranolol
Lignocaine (lidocaine) is often combined with adrenaline (epinephrine) to prolong its duration of action. Adrenaline causes local vasoconstriction, which reduces blood flow at the injection site, slows systemic absorption of lignocaine, and thereby prolongs its local effect. Dopamine, isoprenaline, and propranolol are not used for this purpose.

Immediate rapid IV fluid administration is the most important management in:
A)
Anaphylactic shock
B)
Hypovolaemic shock
C)
Neurogenic shock
D)
Cardiogenic shock
Immediate rapid IV fluid administration is the key treatment in hypovolaemic shock because the primary problem is loss of circulating blood volume or body fluids. Rapid fluid replacement restores intravascular volume, improves venous return, and helps maintain blood pressure and organ perfusion. In anaphylactic shock, adrenaline is the first and most important drug, with fluids as supportive therapy. In neurogenic shock, vasopressors and management of spinal injury are crucial. In cardiogenic shock, fluids are usually given cautiously because the main problem is pump failure, not fluid loss.

Which of the following anti-anxiety drug has minimal sedative effect?
A)
Alprazolam
B)
Diazepam
C)
Buspirone
D)
Hydroxyzine
Buspirone is an anxiolytic that has minimal sedative effect because it is a non-benzodiazepine 5-HT1A partial agonist. In contrast, Alprazolam and Diazepam are benzodiazepines and commonly cause sedation, while Hydroxyzine is an antihistamine with marked sedative properties. Therefore, Buspirone is the correct answer.

The most important reason for giving loading dose of a drug is:
A)
To achieve steady state plasma concentration in a short time
B)
To reduce the complications
C)
When the drugs have long plasma half life
D)
When the drug to be given is acidic
A loading dose is given when it is necessary to quickly reach the desired therapeutic plasma concentration, instead of waiting for several half-lives with repeated maintenance doses. This is especially useful for drugs with a long half-life. Option (c) is a common indication for using a loading dose, but the main reason is option (a): rapid attainment of steady-state/therapeutic concentration. The other options are not the primary purpose of a loading dose.
