ATI Med Surg RESPIRATORY Examination.
Questions and Answers (2025)!!
1. The nurse is caring for a patient with chronic obstructive pulmonary disorder (COPD) and
pneumonia who has an order for arterial blood gases to be drawn. What is the minimum length of
time the nurse should plan to hold pressure on the puncture site?
A. 2 minutes
B. 5 minutes
C. 10 minutes
D. 15 minutes
o B. 5 minutes
After obtaining blood for an arterial blood gas measurement, the nurse should hold
pressure on the puncture site for 5 minutes by the clock to be sure that the bleeding
has stopped. An artery is an elastic vessel under much higher pressure than veins,
and significant blood loss or hematoma formation could occur if the time is
insufficient.
2. A patient with a recent history of a dry cough has had a chest x-ray that revealed the presence
of nodules. To determine whether the nodules are malignant or benign, what is the primary care
provider likely to order?
A. Thoracentesis
B. Pulmonary angiogram
C. CT scan of the patient's chest
D. Positron emission tomography (PET)
o D. Positron emission tomography (PET)
PET is used to distinguish benign and malignant pulmonary nodules. Because
malignant lung cells have an increased uptake of glucose, the PET scan (which uses
an IV radioactive glucose preparation) can demonstrate an increased uptake of
glucose in malignant lung cells. This differentiation cannot be made using CT, a
pulmonary angiogram, or thoracentesis.
