Answer to Question 1

A, B
The nurse should recognize that specimen collection may cause anxiety, embarrassment, and/or discomfort. Cultural considerations are important when collecting specimens and performing diagnostic procedures. Culture and beliefs may affect a patient's response and willingness to participate in specimen collection. Use of a patient's room number is not an acceptable identifier, and the nurse should follow standard precautions when collecting specimens of blood or other body fluids.

Answer to Question 2

C
Clean the site with an antiseptic swab, and allow it to dry completely. Alcohol left on the skin can cause hemolysis of the sample. Hold the finger to be punctured in a dependent position while gently massaging the finger toward the puncture site to increase blood flow to the area before puncture. Select the lateral side of the finger; be sure to avoid the central top of the finger, which has a more dense nerve supply.
