440 CRITICAL CARE NURSING DeMYSTIFIED

8. A patient has a pulmonary artery catheter inserted. When the nurse does the
readings s/he sees a dampened pressure in the range of 7 mm Hg. The most
likely cause for this is the catheter is
A. In the pulmonary capillary wedge position (PCWP or PAOP) and needs to be
aspirated or the physician called to reposition it
B. In the right ventricle as dampened pressures are significant of the catheter
migrating back to the right ventricle; the balloon needs to be inflated
C. In the central vein and needs to be inflated to pass through the tricuspid and
pulmonic valves
D. In the right place and there is no cause for concern

9. A nurse is caring for a patient postoperatively after open-heart surgery. Which
of the following interventions would be included in the care of this patient?
A. Systemic antirejection medications.
B. Annual angiography, echocardiography, and ultrasounds.
C. Temporary pacemaker.
D. Call the physician when two “P” waves are seen on a 12-lead ECG.

10. The patient has aortic stenosis. Which of the following would be an assessment
finding in a patient with aortic stenosis?
A. A harsh blowing murmur over the 5th ICS, MCL Downloaded by [ Faculty of Nursing, Chiangmai University 5.62.158.117] at [07/18/16]. Copyright © McGraw-Hill Global Education Holdings, LLC. Not to be redistributed or modified in any way without permission.
B. Right atrial hypertrophy and pulmonary low pressures
C. A soft radiating murmur over the 5th ICS, MCL
D. Left ventricular hypertrophy, lower systemic pressures

1. A critical care nurse is analyzing a rhythm strip and finds that the atrial and
ventricular rates are 120. The conduction times are normal. This rhythm is most
likely
A. Normal sinus rhythm
B. First-degree AV block
C. Sinus tachycardia
D. Ventricular tachycardia
2. The nurse is measuring the waves and the intervals in a rhythm strip and notes
the P-to-P interval is consistent. The characteristic this nurse is measuring is
A. Ventricular repolarization
B. Atrial regularity
C. Atrial rate
D. Ventricular conduction
