The presence of arterial insufficiency is suspected during an inspection of the lower extremities when the nurse observes:
1. Increased hair growth
2. Cooler skin temperatures
3. Marked edema
4. Brown pigmentation
ANS: 2
In the presence of arterial insufficiency, the client has signs resulting from an absence of blood flow, such as pain, pallor, and decreased or absent pulses in the lower extremities. The lower ex-tremities become dusky red when the extremity is lowered. They feel cool to touch because blood flow is blocked to the extremity. Decreased hair growth or the absence of hair growth over the legs may indicate arterial insufficiency. Marked edema is seen in venous insufficiency, not arterial insufficiency. Brown pigmentation around the ankles is seen in venous insufficiency. Skin changes in arterial insufficiency include thin, shiny skin, decreased hair growth, and thickened nails.

The client tells the nurse that at home, the client was using St. John's wort as a natural treatment for depression, and asks if it is all right to continue taking this herb. What is the nurse's best response? 1. "If it is a natural substance, it should be OK, and you should not have to worry about any drug interactions." 2. "Why are you using an herb? You could treat your depression better with conventional medication." 3. "St. John's wort can decrease the analgesic effect of morphine sulfate. You might want to wait until you no longer need pain management." 4. "As long as you don't take them at the same time, you should be OK. Just space them about two hours apart."
