A medical assistant is preparing a patient who has a history of syncope during blood draws for venipuncture. In which of the following positions should the assistant place the patient?

A. Capillary blood: Capillary blood can be used in some cases, especially in infants, but it is less accurate than arterial blood for measuring blood pH and gases.
B. Arterial blood: Arterial blood is the correct sample for measuring blood pH and gases (such as oxygen and carbon dioxide levels) because it reflects the gas exchange occurring in the lungs.
C. Venous blood: Venous blood is not typically used for measuring blood gases as it does not accurately reflect the oxygenation status of the body.
D. Cerebrospinal fluid: Cerebrospinal fluid is not used for measuring blood pH and gases; it is typically analyzed for conditions affecting the brain and spinal cord.

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.
