Answer to Question 1

B
Feedback:
Chloroquine is currently the mainstay of antimalarial therapy. This drug enters human red blood cells and changes the metabolic pathways necessary for the reproduction of the plasmodium (see Figure 12.1). In addition, this agent is directly toxic to parasites that absorb it, it is acidic, and it decreases the ability of the parasite to synthesize DNA, leading to a blockage of reproduction.

Answer to Question 2

C
Feedback:
The nurse should assess for vision changes and recommend an ophthalmologic examination during treatment to evaluate drug effects on intraocular pressure so that the drug can be stopped if intraocular pressure increases. A rash and changes in cardiac rhythm and rate are possible adverse effects. Also, disorientation (mental status) could be a concern. However, these effects can be treated and may not necessitate stopping the medication.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
