NSG 550 EXAM 2 | COMPREHENSIVE NURSING STUDY GUIDE,
PRACTICE QUESTIONS & ANSWERS 2026/2027
alpha 1 antitrypsin - ANS ✔✔a serum protein produced by the liver normally found in the lungs that
inhibits proteolytic enzymes of white cells from lysing lung tissue; genetic deficiency of this protein can
cause emphysema.
angiotensin converting enzyme (ACE) - ANS ✔✔an enzyme found on the surface of blood vessels in the
lungs and other tissues with aspersive action
cancer tumor markers - ANS ✔✔screen for early cancer
measurement of initial tumor burden
measure of response to anti cancer therapy
detection of recurrent cancer
Carboxyhemoglobin - ANS ✔✔a stable complex of hemoglobin and carbon monoxide that prevents
normal oxygen uptake in the blood.
results of carboxyhemoglobin - ANS ✔✔10-20 symptoms of carbon monoxide
30 severe carbon monoxide poisoning
50-80 deadly
D-dimer - ANS ✔✔degradation product of cross-linked fibrin
Is a D-dimer specific or sensitive? - ANS ✔✔sensitive
NOT SPECIFIC
legionnaires disease antibody - ANS ✔✔in patient's suspected of Legionnaire's disease, found in blood
an antibody
mediastinoscopy - ANS ✔✔visual examination of the mediastinal structures, including the heart,
trachea, esophagus, bronchus, thymus, and lymph nodes
can be used for biopsy
VATS (video-assisted thoracoscopic surgery) - ANS ✔✔a minimally invasive surgical technique used to
diagnose and treat problems in the chest
-a tiny camera (thoracoscope) and surgical instruments are inserted into the chest through small
incisions in the chest wall. Transmit images of the inside of the chest onto a video monitor, guiding the
surgeon in performing the procedure.
gram positive - ANS ✔✔stains purple
staph strep
gram negative - ANS ✔✔red
e.coli
