Answer to Question 1

D
Use the distal (red or brown) lumen to draw blood if the device has more than one lumen. The distal (red or brown) lumen typically is the largest-gauge lumen. Apply clean gloves to prevent transfer of body fluids. Do not flush before drawing blood for blood cultures. If blood cultures have been ordered, do not discard any blood. Use the initial specimen for blood cultures.

Answer to Question 2

A
Antiseptics such as chlorhexidine remove resident and transient bacteria. Alcohol should not be applied after the application of iodophor solution. Chlorhexidine is scrubbed in a back and forth motion for 30 seconds. Allow the antimicrobial solution to air-dry completely. This ensures maximum antimicrobial effect.
