CAA CAA Anesthesia Techniques & Airway Management 3

Question 1

Which inhalation induction agent is preferred for pediatric patients due to its non-pungent, sweet odor?

Accepted Answer

Sevoflurane

Answer

Isoflurane

Answer

Desflurane

Answer

Halothane

Question 2

During a failed airway situation, the 'can't intubate, can't oxygenate' (CICO) scenario is definitively managed with:

Accepted Answer

Emergency front-of-neck access (cricothyrotomy)

Answer

Insertion of an oral airway and two-person bag-mask ventilation

Answer

Repeated laryngoscopy attempts with a video laryngoscope

Answer

Awake fiberoptic intubation

Question 3

Awake fiberoptic intubation is the technique of choice for anticipated difficult airway management primarily because:

Accepted Answer

It preserves the patient's spontaneous breathing and airway reflexes until the airway is secured

Answer

It is faster than direct laryngoscopy in most patients

Answer

It eliminates the need for topical anesthesia

Answer

It is the only technique compatible with full-stomach precautions

Question 4

Postoperative nausea and vomiting (PONV) prophylaxis using ondansetron works by blocking:

Accepted Answer

Serotonin 5-HT3 receptors in the gut and chemoreceptor trigger zone

Answer

Dopamine D2 receptors in the chemoreceptor trigger zone

Answer

Histamine H1 receptors in the vestibular nucleus

Answer

Muscarinic acetylcholine receptors in the CNS

Question 5

The primary advantage of total intravenous anesthesia (TIVA) with propofol-remifentanil over volatile anesthetic-based anesthesia in patients with a history of malignant hyperthermia susceptibility is:

Accepted Answer

Avoidance of triggering agents (volatile anesthetics and succinylcholine)

Answer

Lower incidence of postoperative cognitive dysfunction

Answer

Faster emergence from anesthesia

Answer

Reduced requirement for neuromuscular blockade reversal

Question 6

Transversus abdominis plane (TAP) blocks provide analgesia primarily to which anatomical region?

Accepted Answer

Anterior abdominal wall from T6 to L1 dermatomes

Answer

Pelvic viscera and uterus

Answer

Thoracic wall and pleura

Answer
