The nurse is trying to access the best insertion site on a patient. Which principle would the nurse use to achieve this goal?
a. Avoid using soft, bouncy veins.
b. Choose the patient's best proximal vein.
c. Choose a site large enough for adequate blood flow.
d. Always use the smallest-gauge intravenous (IV) catheter available.
C
The site must be large enough to prevent interruption of venous flow while allowing adequate blood flow around the catheter. The nurse chooses a site for venipuncture with soft, bouncy veins because these veins are more easily punctured and stabilized during the insertion. The most distal vein is the best for insertion to maintain the maximum number of potential sites for future use. The smallest-gauge IV catheter suitable for both the therapy and the patient's vein should be se-lected.

Why would outcomes research use an entire database, rather than merely selecting a sample? (Select all that apply.)
a. Use of the whole database provides an analysis that addresses the entire patient population. b. Permission to use an entire data base implies that the entire data base must be studied. c. Small effect sizes and multiple variables demand huge samples, if statistical significance is to be achieved. d. Accurate determination of risk throughout the system is the focus of outcomes research. e. Cost is not an issue.
