Question 1 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).

The nurse is applying oxygen via nasal cannula to a client diagnosed with chronic obstructive pulmonary disease (COPD). The client complains of extreme shortness of breath. At which rate should the nurse set the flowmeter?
Correct Answer: A

A) to avoid CO2 retention. Higher rates (B, C,
D) risk respiratory drive suppression.
Question 5 of 5
Which statement is correct regarding mycobacterium tuberculosis?
Correct Answer: C
Rationale: Mycobacterium tuberculosis is AEROBIC (it thrives in conditions that are high in oxygen), and it is an ACID-FAST bacterium, which means when it is stained during an acid-fast smear it will turn BRIGHT RED.
