Answer to Question 1

D
Feedback:
The body's inability to effectively cope with carbohydrate, fat, and protein metabolism over a long period of time results in a thickening of the basement membrane in large and small blood vessels. This thickening leads to changes in oxygenation of the lining of the vessels causing damage and narrowing of the vessels. The decreased blood flow through the vessels results in the inability of oxygen to rapidly diffuse across the membrane to the tissues of the eye. The tiny vessels of the eye are narrowed and closed, which causes loss of vision. Increase of aqueous humor is seen in glaucoma. Inability of cell replication and decrease in nerve innervations throughout the eye is not associated with retinopathy.

Answer to Question 2

B
Feedback:
Adverse effects of pancuronium include respiratory depression, apnea, bronchospasm, and cardiac arrhythmias. Rocuronium is associated with pulmonary hypertension, cisatracurium should not be used in neonates, and atracurium is associated with bradycardia.
