Answer to Question 1

D
Feedback:
Hydrostatic pressure pushing fluid out of the capillary is soon higher than the oncotic pressure that is trying to pull the fluid back into the vessel, causing fluid to be lost into the tissues. This shift of fluid accounts for the edema seen in association with HF. This transfer of fluid in the capillaries, called the capillary fluid shift, is carefully regulated by a balance between hydrostatic (fluid pressure) forces on the arterial end of the capillary and oncotic pressure (the pulling pressure of the large, vascular proteins) on the venous end of the capillary. Pulse pressure has nothing to do with edema. Edema pressure and fluid pressure do not exist.

Answer to Question 2

B
Feedback:
Chloroquine (Aralen) can cause ocular toxicity with blurring of vision, color vision changes, corneal damage, and blindness. Increased urination, tingling, and numbness are signs of hyperkalemia and hypokalemia. Loss of balance can be caused by auditory damage due to drug toxicity.
