Answer to Question 1
B
Feedback:
A burn patient loses the protective barrier of the skin and is at risk for infection. In a partial thickness burn, the glands of the skin secrete chemicals that destroy many pathogens and also the normal flora that live on the skin. A cancer patient has decreased cellular defenses. The patient with chickenpox and the patient with pneumonia both have a diminished immune defense along with the prostate cancer patient but still are at less risk for infection than the burn patient.
Answer to Question 2
B
Feedback:
Sympathetic stimulation causes an increase in heart rate, blood pressure, and rate and depth of respirations, as well as a positive inotropic effect (increased force of contraction) on the heart and an increase in blood volume (through the release of aldosterone). A negative inotropic effect would be one that decreased the force of a contraction. A negative dromotropic effect is one that slows the conduction of the impulse through the atrioventricular node. A positive chronotropic effect is one that increases the heart rate.
