OXYGENATION/PERFUSION NCLEX
QUESTIONS WITH CORRECT ANSWERS
GRADED A+ LATEST UPDATE
A client recently fractured his spinal cord at the C-3 level and is at great risk for
developing pneumonia primarily because:
A. The resulting paralysis immobilizes him, and secretions will increase in his
lungs
B. Innervation to the phrenic nerve is absent, preventing chest expansion
C. The resulting abnormal chest shape disallows efficient ventilatory
movement
D. Trauma decreases the ability of his red blood cells to carry oxygen --
ANSWER--B. Innervation to the phrenic nerve is absent, preventing chest
expansion

Which of the following is a likely complication he would experience?
A. Jugular neck vein distention
B. Pulmonary congestion
C. Peripheral edema
D. Liver enlargement --ANSWER--B. Pulmonary congestion

,On admitting a client, the nurse finds that there is a history of myocardial
ischemia. The most disconcerting dysrhythmia for electrocardiography to reveal
is:
A. Sinus bradycardia
B. Paroxysmal supraventricular tachycardia
C. Ventricular tachycardia
D. Premature ventricular contractions --ANSWER--C. Ventricular tachycardia
A client develops acute renal failure and a resulting metabolic acidosis. The
respiratory system compensates by:
A. Hypoventilating and increasing the bicarbonate in the bloodstream
B. Alternating periods of deep versus shallow breaths to maintain homeostasis
of the serum pH
C. Hyperventilating to decrease the serum CO2 and thereby raise the pH
D. Expanding the lung tissues to their fullest, which increases the inspiratory
reserve volumes to provide more oxygen to the tissues --ANSWER--C.
Hyperventilating to decrease the serum CO2 and thereby raise the pH
For a client who is having respiratory symptoms of unknown etiology, the
diagnostic test that is most invasive is:

,A. Pulse oximetry to determine oxygen saturation levels
B. Throat cultures with sterile swabs
C. Bronchoscopy of the bronchial trees
D. Computed tomography of the lung fields --ANSWER--C. Bronchoscopy of
the bronchial trees

specimen and must be suctioned. Which suctioning route is preferred?
A. Nasopharyngeal
B. Nasotracheal
C. Oropharyngeal
D. Orotracheal --ANSWER--B. Nasotracheal
The nurse is caring for a male client with a chest tube. If the chest drainage
system is accidentally disconnected, what should the nurse plan to do?
A. Place the end of the chest tube in a container of sterile saline
B. Apply an occlusive dressing and notify the physician.
C. Clamp the chest tube immediately
D. Secure the chest tube with tape --ANSWER--A. Place the end of the chest
tube in a container of sterile saline

, For a male client with chronic obstructive pulmonary disease, which nursing
intervention would help maintain a patent airway?
A. Restricting fluid intake to 1,000 ml/day
B. Enforcing absolute bed rest
C. Teaching the client how to perform controlled coughing
D. Administering prescribed sedatives regularly and in large amounts --
ANSWER--C. Teaching the client how to perform controlled coughing
Which of the following is true concerning the physiology of the cardiovascular
system?
A. Stimulating the parasympathetic system would cause the heart rate to go up.
B. When a person has heart muscle disease, the heart muscles stretch as far as
is necessary to maintain function.
C. The QRS interval on the electrocardiogram represents the electrical impulses
passing through the ventricles.
D. When stroke volume decreases, there is a resultant decrease in heart rate. --
ANSWER--C. The QRS interval on the electrocardiogram represents the
electrical impulses passing through the ventricles.
The client has emphysema from smoking. During a respiratory system
assessment the nurse anticipates finding:
