Study goals should set out exactly what you want to

STUDY TIP: Answer every question. A question without an answer is the same as a wrong answer. Go ahead
and guess. You have studied for the test and you know the material well. You are not making a random guess
based on no information. You are guessing based on what you have learned and your best assessment of the
question.
Rationale
Placing the client in the supine position before changing the tubing decreases pressure in the vena cava,
which helps prevent an air embolus when the catheter is disconnected. Infusion of high concentrations of
glucose will cause hypervolemia, not hypovolemia. The infusion rate is changed only with a health care
provider’s prescription. Although insulin is contained in the parenteral nutrition formula, when blood glucose
levels become elevated the health care provider may prescribe insulin coverage. No medications or solutions
other than the parenteral nutrition should be administered through this line.
Test-Taking Tip: Attempt to select the answer that is most complete and includes the other answers within it.
For example, a stem might read, "A child’s intelligence is influenced by what?" and three options might be
genetic inheritance , environmental factors , and past experiences . The fourth option might be multiple factors,
which is a more inclusive choice and therefore the correct answer.
Study goals should set out exactly what you want to accomplish. Do not simply say, "I will study
for the exam." Specify how many hours, what day and time, and what material you will cover.

Rationale
Obtaining the client’s vital signs provides a baseline and should be done before the transfusion is initiated.
Before beginning the transfusion, the nurse and another hospital-approved personnel should double-check
client identification and blood product identification (blood unit number, blood type, and crossmatch data like
Rh factor along with expiration date) with another licensed nurse. Using a Y-type infusion set with 0.9% saline
on one side of the Y is necessary to prevent an acute immunologic reaction if the donated blood is not
compatible with the client’s blood. A Y-type infusion set is specific for blood administration. It has a special
blood filter, the drop factor is di ff erent, and it allows for quick shuto ff and the administration of normal saline
in the event of a transfusion reaction. The laboratory results for hemoglobin and hematocrit levels were part
of the data used to determine the need for blood initially and do not need to be performed again until after
the transfusion is completed. Blood must be kept cold until ready for use; after it is started, blood must be
administered within 4 hours.
