Answer to Question 1
Ans:
C
Feedback:
Under conditions of decreased perfusion or increased sympathetic nervous system stimulation, blood flow is redistributed away from the cortex toward the medulla. This redistribution of blood flow decreased glomerular filtration while maintaining the urine-concentrating ability of the kidneys, a factor that is important during conditions such as shock. The urine output would not increase, nor be normal.
Answer to Question 2
Ans:
A
Feedback:
The vocal folds contribute to blocking of the airways during swallowing; compromise to this function is likely to allow food to enter the lungs. The epiglottis is performing its normal, protective role against aspiration when it covers the larynx, and the vocal folds contribute to sound enunciation, not swallowing or protection against aspiration. Tracheobronchial obstruction would not contribute to aspiration.
