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 - CORRECT ANSWERS ✔✔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 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. |\ |\
A patient with a recent history of a dry cough has had a chest x-
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
ray that revealed the presence of nodules. In an effort 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) - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\
✔✔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 increased uptake of glucose in |\ |\ |\ |\ |\ |\ |\ |\
malignant lung cells. This differentiation cannot be made using
|\ |\ |\ |\ |\ |\ |\ |\ |\
CT, a pulmonary angiogram, or thoracentesis.
|\ |\ |\ |\ |\
After assisting at the bedside with a thoracentesis, the nurse
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
should continue to assess the patient for signs and symptoms of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
what?
A. Bronchospasm
|\
B. Pneumothorax
|\
C. Pulmonary edema
|\ |\
D. Respiratory acidosis - CORRECT ANSWERS ✔✔B.
|\ |\ |\ |\ |\ |\ |\
Pneumothorax
Because thoracentesis involves the introduction of a catheter into
|\ |\ |\ |\ |\ |\ |\ |\
the pleural space, there is a risk of pneumothorax. Thoracentesis
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
does not carry a significant potential for causing bronchospasm,
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
pulmonary edema, or respiratory acidosis. |\ |\ |\ |\
, The patient had abdominal surgery yesterday. Today the lung
|\ |\ |\ |\ |\ |\ |\ |\ |\
sounds in the lower lobes have decreased. The nurse knows this
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
could be due to what occurring?
|\ |\ |\ |\ |\
A. Pain
|\
B. Atelectasis
|\
C. Pneumonia
|\
D. Pleural effusion - CORRECT ANSWERS ✔✔B. Atelectasis
|\ |\ |\ |\ |\ |\ |\
Postoperatively there is an increased risk for atelectasis from |\ |\ |\ |\ |\ |\ |\ |\ |\
anesthesia as well as restricted breathing from pain. Without
|\ |\ |\ |\ |\ |\ |\ |\ |\
deep breathing to stretch the alveoli, surfactant secretion to hold
|\ |\ |\ |\ |\ |\ |\ |\ |\
the alveoli open is not promoted. Pneumonia will occur later
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
after surgery. Pleural effusion occurs because of blockage of
|\ |\ |\ |\ |\ |\ |\ |\ |\
lymphatic drainage or an imbalance between intravascular and
|\ |\ |\ |\ |\ |\ |\ |\
oncotic fluid pressures, which is not expected in this case
|\ |\ |\ |\ |\ |\ |\ |\ |\
The patient is hospitalized with pneumonia. Which diagnostic test
|\ |\ |\ |\ |\ |\ |\ |\
should be used to measure the efficiency of gas transfer in the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
lung and tissue oxygenation?
|\ |\ |\
A. Thoracentesis
|\
B. Bronchoscopy
|\
C. Arterial blood gases
|\ |\ |\
D. Pulmonary function tests - CORRECT ANSWERS ✔✔C. Arterial
|\ |\ |\ |\ |\ |\ |\ |\ |\
blood gases |\
