When using the Z-track technique, the nurse should use the side of the hand to pull the tissue laterally about 1 in. (2.5 cm) until the tissue is taut. The needle is depressed with the thumb, not the finger, and the needle should be left in place for several seconds following injection. Massage is contraindicated.
Answer to Question 2
A
Feedback:
The nurse should use a colloid solution to replace the circulating blood in the client. Colloid solutions such as blood, blood products, and solutions known as plasma expanders are used to replace circulating blood volume because the suspended molecules pull fluid from other compartments. Hypertonic solution is not used very frequently except in extreme cases when it is necessary to reduce cerebral edema or to expand the circulatory volume rapidly. Hypotonic solution is administered to clients with fluid losses in excess of fluid intake, such as those who have diarrhea or vomiting. Isotonic solution is administered to maintain fluid balance in clients who may not be able to eat or drink for a short period. These solutions are not used to replace severe losses of circulating blood.
