Answer to Question 1

A
Feedback:
The valve between the atrium and ventricle on the left side of the heart, called the mitral or bicuspid valve, is composed of two leaflets or cusps that allow the left ventricle to fill with blood and then close to prevent backflow of blood into the left atrium. If this valve is damaged, contraction of the ventricle will push blood back into the left atrium and result in inadequate cardiac output. The pulmonic valve is located between the right ventricle and pulmonary artery. The aortic valve allows blood to flow from the left ventricle into the aorta. The tricuspid valve is the valve between the right atria and ventricle.

Answer to Question 2

B
Feedback:
An adverse effect of antihistamines is drowsiness, so that injury to the patient or others can occur if driving or operating machinery. An increase in fluids would be indicated to help keep nasal membranes moist. It is common for dreams to occur when taking medication and it is not necessary to report them. Dietary fat should not interfere with the drug metabolism of antihistamines.
