Question 2 of 5

The client is suspected of having a pulmonary embolus. Which diagnostic test suggests the presence of a pulmonary embolus and requires further investigation?

A) suggests clotting, warranting further PE investigation (e.g., CT). ABGs (

Question 3 of 5

A patient's D-dimer result is <500 ng/mL (FEU). The nurse knows that the D-dimer assesses and this result means?

Correct Answer: D

Rationale: A d-dimer test assess fibrin degradation fragment. This test doesn't tell us where the clot may be (so it not specific) so it will need to be further investigated by the MD and a positive result doesn't necessarily mean the patient has a clot because some disease processes can cause a false positive. Also, a normal d-dimer is <500 ng/mL (FEU). However, it depends on how the lab reports the assay cut-off value for the d-dimer. Some labs have a cutoff <250 ng/mL (D-DU). However, <500 ng/mL (FEU) is equivalent to <250 ng/mL (D-DU).
