Which of the following laboratory tests are performed to help determine the nutritional status of a client considered high risk for heart surgery?

A) Complete blood count
B) Cardiac enzymes
C) Troponin
D) Albumin and pre-albumin

Albumin and pre-albumin are laboratory tests commonly used to assess the nutritional status of a client. Clients who are considered high risk for heart surgery may be at an increased risk for malnutrition, and therefore monitoring their nutritional status with these tests can be helpful in optimizing their outcomes. A complete blood count and cardiac enzymes are not specific indicators for nutritional status and troponin is a marker for heart damage, not nutrition.
