A medical assistant needs to collect four tubes during a blood draw. Which of the following tubes should be filled last?

A. Place the arm electrodes facing downward. The arm electrodes should be placed with the tabs facing downward to reduce the risk of artifacts on the EKG tracing caused by movement or improper lead contact.
B. Place the electrodes over bony prominences when possible. Electrodes should not be placed over bony prominences, as this can interfere with the accuracy of the EKG reading. Instead, they should be placed on soft tissue.
C. Place the leg electrodes downward. Leg electrodes should also be placed with the tabs facing downward to prevent artifacts, similar to the arm electrodes.
D. Place the chest electrodes in a straight line just below the nipple. Chest electrodes should be placed according to specific anatomical landmarks, not in a straight line, to ensure accurate heart rhythm tracing.

A. Support group: A support group can provide emotional support, information, and shared experiences relevant to managing a new medical diagnosis.
B. Department of Social Services: While the Department of Social Services may assist with various needs, such as financial or housing assistance, it is not specifically focused on the emotional and informational support for a new diagnosis.
C. Food bank: A food bank is primarily for food distribution and would not directly address the challenges of managing a new medical diagnosis.
D. Local department of health: Although the local department of health may provide resources or referrals, a support group would be more focused on the emotional and practical aspects of dealing with a new diagnosis.
