Question 2

A conscious patient who ingested an overdose of local anesthetic begins experiencing perioral numbness and metallic taste. These are signs of toxicity affecting which system first?

Accepted Answer

Central nervous system

Answer

CNS toxicity from local anesthetic overdose manifests first with perioral numbness, tinnitus, metallic taste, and agitation before progressing to cardiovascular collapse.

Question 3

Which position is recommended for a pregnant patient who becomes hypotensive in the dental chair?

Accepted Answer

Left lateral tilt (15-30 degrees)

Left lateral tilt displaces the gravid uterus off the inferior vena cava, relieving supine hypotensive syndrome by restoring venous return in the third trimester.

Question 4

A patient with a history of adrenal insufficiency is undergoing a lengthy, stressful procedure. Which emergency is this patient at risk for?

Accepted Answer

Addisonian (adrenal) crisis

Answer

Patients with adrenal insufficiency cannot produce adequate cortisol in response to surgical stress, potentially triggering an Addisonian crisis with profound hypotension.

A conscious patient who can swallow should receive oral glucose (gel, juice, or glucose tablets) as the safest and most practical first-line treatment for hypoglycemia.
