SOLUTION RATED A+ FOR SUCCESS




Both hemodynamic parameters and the reported hematocrit value indicate hypovolemia
and blood loss requiring volume resuscitation with blood products. Furosemide
administration will worsen fluid volume status. Inotropic agents will not correct the
underlying fluid volume deficit and anemia. Vasoconstrictors are contraindicated in a
volume-depleted state. - CORRECT ANSWERS A patient is admitted to the hospital with
multiple trauma and extensive blood loss. The nurse assesses vital signs to be BP 80/50 mm
Hg, heart rate 135 beats/min, respirations 36 breaths/min, cardiac output (CO) of 2 L/min,
systemic vascular resistance of 3000 dynes/sec/cm-5, and a hematocrit of 20%. The nurse
anticipates administration of which the following therapies or medications?
a.
Blood transfusion
b.
Furosemide (Lasix)
c.
Dobutamine (Dobutrex) infusion
d.
Dopamine hydrochloride (Dopamine) infusion


ANS: C


The pulmonary pressures are higher than normal, indicating elevated preload, and the
cardiac index and output values are low. The priority order for the nurse to implement is to
begin a dobutamine (Dobutrex) infusion to improve cardiac output, possibly reducing
pulmonary artery occlusion pressures. The other treatments are important, but the
dobutamine infusion is the most important at this time. - CORRECT ANSWERS After

,pulmonary artery catheter insertion, the nurse assesses a pulmonary artery pressure of
45/25 mm Hg, a pulmonary artery occlusion pressure (PAOP) of 20 mm Hg, a cardiac output
of 2.6 L/min and a cardiac index of 1.9 L/min/m2. Which physician order is of the highest
priority?
a.
Apply 50% oxygen via venture mask.
b.
Insert an indwelling urinary catheter.
c.
Begin a dobutamine (Dobutrex) infusion.
d.
Obtain stat cardiac enzymes and troponin.


ANS: B
Numbness and tingling in the left hand, which is the location of an arterial catheter, indicates
possible neurovascular compromise and requires immediate action. A dampened waveform
can indicate problems with arterial line patency but is not an emergent situation. Slight
bloody drainage at the subclavian insertion site is not an unusual finding. Slight redness at
the insertion site, while of concern, does not require immediate action. - CORRECT
ANSWERS The nurse is caring for a patient with a left subclavian central venous catheter
(CVC) and a left radial arterial line. Which assessment finding by the nurse requires
immediate action?
a.
A dampened arterial line waveform
b.
Numbness and tingling in the left hand
c.
Slight bloody drainage at subclavian insertion site
d.
Slight redness at subclavian insertion site


ANS: B
Upon removal of an invasive arterial line, adequate pressure must be applied for at least 5
minutes to ensure adequate hemostasis. Application of an air occlusion dressing is not
standard of care following removal of an arterial line. Elevation of the affected limb following

,removal of an arterial line is not a necessary intervention. Neutral wrist position is optimum
while the catheter is in place and not necessary after catheter discontinuation. - CORRECT
ANSWERS The physician writes an order to discontinue a patient's left radial arterial line.
When discontinuing the patient's invasive line, what is the priority nursing action?
a.
Apply an air occlusion dressing to insertion site.
b.
Apply pressure to the insertion site for 5 minutes.
c.
Elevate the affected limb on pillows for 24 hours.
d.
Keep the patient's wrist in a neutral position.


ANS: C
X-ray results indicate proper position of the catheter. The tip of the central venous catheter
should rest just above the right atrium in the superior vena cava. The central venous
catheter is positioned correctly in the superior vena cava. Dysrhythmias occur if the catheter
migrates to the right ventricle. Central venous catheters are placed into great vessels of the
venous system and not advanced into the pulmonary artery. - CORRECT ANSWERS
Following insertion of a central venous catheter, the nurse obtains a stat chest x-ray film to
verify proper catheter placement. The radiologist reports to the nurse: "The tip of the
catheter is located in the superior vena cava." What is the best interpretation of these
results by the nurse?
a.
The catheter is not positioned correctly and should be removed.
b.
The catheter position increases the risk of ventricular dysrhythmias.
c.
The distal tip of the catheter is in the appropriate position.
d.
The physician should be called to advance the catheter into the pulmonary artery.


ANS: C
Balloon inflation should never be forced because the PAC may have migrated further into the
pulmonary artery, creating resistance to balloon inflation. Verification of proper line

, placement is warranted to avoid pulmonary artery rupture. In addition, the PAC waveform
should be observed to assist in identifying location of the tip of the PAC. In this scenario,
adding additional air to the balloon will further risk pulmonary artery rupture.
Advancing a pulmonary artery catheter is not within the nurse's scope of practice.
Flushing the distal port with saline may be indicated to ensure patency; however, the
balloon of the PAC should never be locked in the inflated position as rupture of the
pulmonary artery may occur. - CORRECT ANSWERS 10. While inflating the balloon of a
pulmonary artery catheter (PAC) with 1.0 mL of air to obtain a pulmonary artery occlusion
pressure (PAOP), the nurse encounters resistance. What is the best nursing action?
a.
Add an additional 0.5 mL of air to the balloon and repeat the procedure.
b.
Advance the catheter with the balloon deflated and repeat the procedure.
c.
Deflate the balloon and obtain a chest x-ray study to determine line placement.
d.
Lock the balloon in the inflated position and flush the distal port of the PAC with normal
saline.


ANS: A
Diminished breaths sounds over the lung field on the same side of the line insertion site may
be indicative of a pneumothorax. A pneumothorax, which can develop slowly, is a major
complication following insertion of central lines when the subclavian route is used. Localized
pain at catheter insertion site is not the immediate priority in this scenario. A measured
central venous pressure of 5 mm Hg is normal. Slight bloody drainage at the insertion site
soon after the procedure does not require immediate action. - CORRECT ANSWERS The
nurse is caring for a patient following insertion of a left subclavian central venous catheter
(CVC). Which assessment finding 2 hours after insertion by the nurse warrants immediate
action?
a.
Diminished breath sounds over left lung field
b.
Localized pain at catheter insertion site
c.
Measured central venous pressure of 5 mm Hg
d.
