Question 1

Which intravenous induction agent is associated with pain on injection, dose-dependent respiratory depression, and is commonly used for procedural sedation?

Accepted Answer

Propofol

Answer

Propofol causes dose-dependent respiratory depression and pain at injection; its rapid onset, short duration, and antiemetic properties make it widely used for induction and sedation.

Question 2

Which anesthetic agent is known to produce a dissociative state, provide analgesia, and is contraindicated in patients with elevated intracranial pressure?

Accepted Answer

Ketamine

Answer

Ketamine produces dissociative anesthesia with preserved airway reflexes and analgesia, but increases cerebral blood flow and intracranial pressure, making it relatively contraindicated in head injury.

Question 3

What is the significance of the 'cannot intubate, cannot oxygenate' (CICO) scenario in anesthesia?

Accepted Answer

It is a failed airway emergency requiring surgical airway

Answer

CICO is a life-threatening failed airway scenario where all attempts at ventilation and intubation fail, requiring immediate surgical airway (cricothyrotomy).

Question 4

Which opioid is known to cause histamine release, resulting in hypotension, bronchospasm, and pruritus when given rapidly IV?

Accepted Answer

Morphine

Answer

Morphine causes histamine release from mast cells, which can precipitate bronchospasm, hypotension, and pruritus, especially with rapid intravenous administration.

Question 5

A drug labeled 'Pitocin' is requested during an obstetric procedure. What is the mechanism of action of this drug?

Accepted Answer

It stimulates uterine contractions to control postpartum hemorrhage

Answer

Pitocin (oxytocin) stimulates uterine smooth muscle contractions and is administered after delivery to reduce postpartum hemorrhage.
