Answer to Question 1

Ans:
C, D, E

Feedback:

With midbrain involvement, pupils are fixed and midsized (5 mm in diameter), and reflex adduction of the eyes is impaired; pain elicits decerebrate posturing; and respirations change from Cheyne-Stokes respiration to neurogenic hyperventilation. Cloudiness of consciousness occurs in early diencephalic stages. Decorticate posturing with pain occurs in the diencephalic stage.

Answer to Question 2

Ans:
A

Feedback:

Botulism in infants is frequently attributable to honey. Family history is not a relevant consideration given the bacterial etiology, and mold and chemical cleaning products are not known to predispose to botulism toxicity.
