Answer to Question 1

Correct Answer: 2
Rationale: Baroreceptors sense and relay changes in blood pressure. Chemoreceptors recognize levels of oxygen, carbon dioxide, and pH levels.

Answer to Question 2

Correct Answer: 3
Rationale: Doxazosin (Cardura) is selective for blocking alpha1-receptors in vascular smooth muscle, which results in dilation of arteries and veins. Excreting more urine is an effect of diuretic medications. Increasing the efficiency of the heart is not an effect of doxazosin (Cardura). Decreasing the release of stress hormones is not an effect of doxazosin (Cardura).
