ANSWER

Correct answer: c Rationale: An individualized plan of care should be developed for each patient and the

ANSWER

Correct answers: b, c, d, e Rationale: The hemodynamic effects of intraaortic balloon inflation during dia

stole include increased diastolic blood pressure (BP), increased pressure in the aortic root, increased co

ronary artery perfusion pressure, and improved oxygen delivery to the myocardium. The hemodynamic

effects of intraaortic balloon inflation during systole include decreased afterload (i.e., systemic vascular

resistance [SVR]), decreased peak systolic pressure, decreased myocardial oxygen consumption, increas

ANSWER

Rationale: Positive end- vc vc



expiratory pressure (PEEP) is a ventilatory maneuver in which positive pressure is applied to the airwa
vc vc vc vc vc vc vc vc vc vc vc vc vc vc vc



y during exhalation. This increases functional residual capacity (FRC) and often improves oxygenation w

ith restoration of lung volume that normally remains at the end of passive exhalation.

QUESTION 4 vc




7. The nursing management of a patient with an artificial airway includes
vc vc vc vc vc vc vc vc vc vc vc



a. maintaining ET tube cuff pressure at 30 cm H2O.
vc vc vc vc vc vc vc vc vc



b. routine suctioning of the tube at least every 2 hours.

c. observing for cardiac dysrhythmias during suctioning.

d. preventing tube dislodgment by limiting mouth care to lubrication of the lips.
vc vc vc vc vc vc vc vc vc vc vc vc




ANSWER

Correct answer: c Rationale: Potential complications associated with suctioning include hypoxemia, bron
vc vc vc vc vc vc vc vc vc vc vc



chospasm, increased intracranial pressure, dysrhythmias, hypertension, hypotension, mucosal damage, p
vc vc vc vc vc vc vc vc vc



ulmonary bleeding, pain, and infection. Closely assess the patient before, during, and after the suctioning
vc vc vc vc vc vc vc vc vc vc vc vc vc vc



procedure. If the patient does not tolerate suctioning (e.g., decreased arterial oxygenation, increased or
vc vc vc vc vc vc vc vc vc vc vc vc vc vc vc



decreased blood pressure, sustained coughing, development of dysrhythmias), stop the procedure, and
vc vc vc vc vc vc vc vc vc vc vc vc



manually hyperventilate the patient with a bag valve mask and 100% oxygen.
