LOCAL ANAESTHESIA MCQS-Quiz-Test
LOCAL ANAESTHESIA MCQS-Quiz-Test
Local anaesthesia is an important part of modern medical practice, offering a targeted approach to pain management and anaesthesia for various procedures. Understanding the properties of local anaesthetic drugs and techniques is crucial for medical professionals across different specialties. From lignocaine to bupivacaine, each drug has unique properties and considerations should be done regarding dosage, onset, and duration of action.
Here is the MCQs on LOCAL ANAESTHESIA as quiz or test. These MCQs are prepared to fulfil the requirement for all types of medical exams as NEET, USMLE, PLAB, Promatric and ALL TYPES OF MEDICAL BOARD Exams all over the world.
Results
#1. What precaution should be taken when using local anaesthetics in end-arterial locations? ? Avoid using adrenaline
Avoid using adrenaline
Adrenaline should be avoided in end-arterial locations due to the risk of vascular compromise and tissue necrosis.
#2. A patient presents for a minor surgical procedure on the forearm. Which local anaesthetic drug would be most appropriate to use if you want to minimize cardiotoxicity? ? Ropivacaine
Ropivacaine
Ropivacaine has less cardiotoxicity compared to other options like bupivacaine. It provides a good sensory-motor separation and is suitable for peripheral nerve blocks.
#3. What is the maximum dose of prilocaine when adrenaline is added to the solution? ? 9 mg/kg
9 mg/kg
The addition of adrenaline increases the maximum recommended dose of prilocaine to 9 mg/kg, which helps in prolonging its duration of action.
#4. Which local anaesthetic drug is an isomer of bupivacaine but has fewer cardiotoxic properties? ? Levobupivacaine
Levobupivacaine
Levobupivacaine is an isomer of bupivacaine with less cardiotoxicity, making it a safer option for local anaesthesia.
#5. A 50-year-old patient with a history of cardiovascular disease requires a local anaesthetic for a dental procedure. Which drug should be avoided due to its potential exacerbation of cardiovascular issues? ? Bupivacaine
Bupivacaine
Bupivacaine is more cardiotoxic and must be avoided in patients with cardiovascular disease due to the risk of arrhythmias and cardiac arrest.
#6. What is the maximum recommended dose of lignocaine when used without adrenaline? ? 3 mg/kg
3 mg/kg
Lignocaine can be administered up to a maximum dose of 3 mg/kg without adrenaline, providing a good sensory block.
#7. What is the primary advantage of adding adrenaline to a local anaesthetic solution? ? Prolongs duration of action
Prolongs duration of action
Adrenaline added to a local anaesthetic solution prolongs its duration of action, allowing for longer-lasting anaesthesia.
#8. Which local anaesthetic drug should never be used intravenously due to its potential for severe cardiotoxicity? ? Bupivacaine
Bupivacaine
Bupivacaine has a high risk of cardiotoxicity and should never be used intravenously to avoid severe complications.
#9. Which local anaesthetic drug has the property of early onset, short duration of action, and provides a good sensory block? ? Lignocaine
Lignocaine
Lignocaine exhibits early onset and short duration of action, making it suitable for various procedures requiring local anaesthesia.
#10. What are the potential complications associated with local anaesthesia techniques? ? Local haematoma and systemic complications
Local haematoma and systemic complications
Local anaesthesia techniques can lead to local complications such as haematoma and systemic complications like overdose or accidental intravascular injection.
#11. Which local anaesthetic drug is associated with the risk of causing methaemoglobinaemia in overdose situations? ? Prilocaine
Prilocaine
Prilocaine overdose can lead to methaemoglobinaemia, which is a serious complication associated with its use.
#12. A patient with a history of tricyclic antidepressant use requires local anaesthesia for a minor procedure. Which drug should be avoided due to potential interactions? ? Prilocaine
Prilocaine
Prilocaine should be avoided in patients taking tricyclic antidepressants due to the risk of interaction and potential toxicity.
