getting a venous sample and switched over to dermal punctures to finish out the later
three glucose tests. The pbt decision: - ✔✔Compromises the test interpretation venous
glucose levels are lower than capillary levels.

punctured an artery during your venous draw. How should you proceed? - ✔✔Complete
the draw and label the specimen arterial
