Free anesthesiology MCQ exam model for clinical students

Explanation:

• Succinylcholine → Correct because it has rapid onset and short duration.

• Vecuronium → Incorrect because onset is slower.

• Atracurium → Incorrect because it is not rapid enough.

• Rocuronium → Incorrect because it is an alternative but not most common.

• Pancuronium → Incorrect because it has long duration.

Explanation:

• Hypotension → Correct because sympathetic blockade causes vasodilation.

• Respiratory depression → Incorrect because it is rare in spinal anesthesia.

• Hypertension → Incorrect because blood pressure usually falls.

• Bradyarrhythmia → Incorrect because it may occur but hypotension is more common.

• Pulmonary edema → Incorrect because it is rare.

Explanation:

• Bupivacaine → Correct because it provides long-lasting anesthesia and analgesia.

• Lidocaine → Incorrect because it is intermediate acting.

• Prilocaine → Incorrect because it is intermediate acting.

• Procaine → Incorrect because it is short acting.

• Chloroprocaine → Incorrect because it is very short acting.

Explanation:

• Propofol → Correct because it provides rapid, smooth induction and recovery.

• Thiopentone → Incorrect because it is less commonly used now.

• Ketamine → Incorrect because it is used in specific situations.

• Midazolam → Incorrect because it is mainly a sedative.

• Etomidate → Incorrect because it is used in hemodynamically unstable patients.

Explanation:

• Better postoperative analgesia → Correct because regional blocks provide prolonged pain relief.

• Complete unconsciousness → Incorrect because patient remains conscious.

• Higher complication rate → Incorrect because complications are fewer in experienced hands.

• Prolonged recovery time → Incorrect because recovery is often faster.

• Increased airway manipulation → Incorrect because airway is usually not instrumented.

Explanation:

• Intravenous → Correct because IV induction is rapid and reliable.

• Intramuscular → Incorrect because onset is slow.

• Subcutaneous → Incorrect because absorption is unpredictable.

• Oral → Incorrect because it is not used for induction.

• Intradermal → Incorrect because it is used for testing only.

Explanation:

• Succinylcholine → Correct because it triggers abnormal calcium release in susceptible individuals.

• Propofol → Incorrect because it is safe in malignant hyperthermia.

• Nitrous oxide → Incorrect because it does not trigger the condition.

• Midazolam → Incorrect because it is a benzodiazepine.

• Local anesthetics → Incorrect because they are not triggers.

Explanation:

• Naloxone → Correct because it is a pure opioid antagonist.

• Flumazenil → Incorrect because it reverses benzodiazepines.

• Atropine → Incorrect because it treats bradycardia.

• Neostigmine → Incorrect because it reverses non-depolarizing muscle relaxants.

• Protamine → Incorrect because it reverses heparin.

Explanation:

• Pain relief and perioperative care → Correct because anesthesiology focuses on anesthesia, analgesia, and perioperative management.

• Diagnosis of surgical diseases → Incorrect because this is surgery/medicine.

• Surgical techniques → Incorrect because this is the surgeon’s role.

• Postoperative nursing care → Incorrect because this is nursing care.

• Radiological imaging → Incorrect because this is radiology.

Explanation:

• Assess and reduce anesthetic risk → Correct because evaluation identifies comorbidities and optimizes patient safety.

• Select surgical procedure → Incorrect because this is surgeon’s role.

• Decide postoperative diet → Incorrect because this is postoperative care.

• Choose antibiotics → Incorrect because this is infection control.

• Determine hospital stay duration → Incorrect because it depends on surgery and recovery.
