DAANCE Anesthesia Techniques 2

Question 1

Which technique is used to prevent unintentional intravascular injection of local anesthetic?

Accepted Answer

Aspirating before injection to check for blood return

Answer

Aspiration before injection checks for blood in the syringe, indicating intravascular needle placement. Negative aspiration reduces (but does not eliminate) intravascular injection risk.

Question 2

Inhalation sedation with nitrous oxide/oxygen (N2O/O2) is MOST appropriate for which patient?

Accepted Answer

A mildly anxious, cooperative adult for a routine restoration

Answer

A mildly anxious, cooperative adult with no contraindications is the ideal candidate for nitrous oxide/oxygen sedation.

Question 3

The technique of titration in IV sedation means:

Accepted Answer

Incrementally administering small doses and assessing response before giving more

Answer

Titration involves giving small incremental doses, pausing to assess clinical effect, and proceeding only if more sedation is needed - preventing inadvertent oversedation.

Question 4

Which statement about the IV induction drug propofol is CORRECT?

Accepted Answer

It requires a separate analgesic agent because it provides no analgesia

Answer

Propofol provides sedation, hypnosis, and amnesia but NO analgesia. An opioid or local anesthetic must be used concurrently for painful procedures.

Question 5

The concept of rescue in monitored anesthesia care (MAC) sedation means the provider must be capable of:

Accepted Answer

Rescuing a patient who moves to a deeper level of sedation than intended

Answer

Rescue capability requires that the provider can recognize and manage inadvertent deep sedation or loss of airway, including bag-valve-mask ventilation and reversal drug administration.
