25 terms shelbycar99Preview NURS 2160 Oxygen therapy NCLEX ...15 terms Gunveen_dureja Preview FINAL 28 terms Mh Which of the following is true concerning the physiology of the cardiovascular system?

• Stimulating the parasympathetic system would cause the heart rate to go up.
• When a person has heart muscle disease, the heart muscles stretch as far as is necessary to maintain function.
• The QRS interval on the electrocardiogram represents the electrical impulses passing through the ventricles.
• When stroke volume decreases, there is a resultant decrease in heart rate.
• 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:

• Abnormal palpation signs in the upper thorax
• Dull sounds on percussion
• A depressed sternum on inspection
• Moist breath sounds on auscultation
• Dull sounds on percussion

A 64-year-old client is seen in the emergency room for palpitations and mild shortness of breath. The ECG reveals a normal P wave, P-R interval, and QRS complex with a regular rhythm and rate of 108. The nurse should recognize this cardiac dysrhythmia as:

• Sinus dysrhythmia
• Sinus tachycardia
• Supraventricular tachycardia
• Ventricular tachycardia
• Sinus tachycardia

The client has experienced a myocardial infarction damaging the right ventricle. Which of the following is a likely complication he would experience?

• Jugular neck vein distention
• Pulmonary congestion
• Peripheral edema
• Liver enlargement
• 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:

• Sinus bradycardia
• Paroxysmal supraventricular tachycardia
• Ventricular tachycardia
• Premature ventricular contractions
• Ventricular tachycardia

A client develops acute renal failure and a resulting metabolic acidosis. The respiratory system compensates by:

• Hypoventilating and increasing the bicarbonate in the bloodstream
• Alternating periods of deep versus shallow breaths to maintain homeostasis of the serum pH
• Hyperventilating to decrease the serum CO2 and thereby raise the pH
• Expanding the lung tissues to their fullest, which increases the inspiratory reserve volumes to provide more oxygen to the tissues
• 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:

• Pulse oximetry to determine oxygen saturation levels
• Throat cultures with sterile swabs
• Bronchoscopy of the bronchial trees
• Computed tomography of the lung fields
• Bronchoscopy of the bronchial trees

The nurse identifies that the client is unable to cough to produce a sputum specimen and must be suctioned. Which suctioning route is preferred?

• Nasopharyngeal
• Nasotracheal
• Oropharyngeal
• Orotracheal
• Nasotracheal

To help the client prevent postoperative pulmonary complications preoperatively, the nurse should:

• Ask the physician to order nebulizer treatments
• Teach the client to do leg exercises
• Teach the client to use a flow-oriented incentive spirometer
• Tell the client that if he does not cough, he may need to be suctioned
• Teach the client to use a flow-oriented incentive spirometer

Myocardial blood flow is unidirectional; the nurse knows that the correct pathway is which of the following?

• Right atrium, right ventricle, left ventricle, left atrium
• Right atrium, left atrium, right ventricle, left ventricle
• Right atrium, right ventricle, left atrium, left ventricle
• Right atrium, left atrium, left ventricle, right ventricle

carotid artery supplies blood to the brain.

• Right atrium, right ventricle, left atrium, left ventricle

The nurse caring for a patient with ischemia to the left coronary artery would expect to find

• Increased ventricular diastole.
• Increased stroke volume.
• Decreased preload.
• Decreased afterload.
• Decreased afterload.

A patient's heart rate increased from 80 bpm to 160 bpm. The nurse knows that what will follow is a(n)

• Increase in diastolic filling time.
• Decrease in cardiac output.
• Increase in stroke volume.
• Increase in contractility.
• Decrease in cardiac output.

When an excess of body fluid exists in the intravascular compartment, all of the following signs can be expected except:

• Rales
• A bounding pulse
• Engorged peripheral veins
• An elevated hematocrit level
• An elevated hematocrit level

What does hypoventilation lead to (more than one)?

• Hypercarbia
• Hypoxemia
• Cyanosis
• Hypoxia
• Hypercarbia
• Hypoxia

What is Kussmauls breathing?

• A type of hyperventilation
• A type of hypoventialation
• A type of apnea
• A synonym for dyspnea
• A type of hyperventilation

Which of the following are reasons a client may be experiencing Cheyne-stokes respirations? (a marked rhythmic waxing and waning of respirations from very deep to very shallow breathing and temporary apnea)

A. CHF

• Central nervous system disorder
• Increased intracranial pressure
• Overdose of certain drugs

A. CHF

• Increased intracranial pressure
• Overdose of certain drugs

Which of the following steps is not used to percuss a clients chest to dislodge mucus (more than one)?

• Make sure the area percussed is open and free of any clothing
• Ask client to breath slowly and shallowly to promote relaxation
• Rapidly slap the chest by flexing and extending the wrists
• Percuss each lung segment for 1-2 minutes
• Percuss all fields of the lung, including breasts, sternum and spinal column
• Make sure the area percussed is open and free of any clothing
• Ask client to breath slowly and shallowly to promote relaxation
• Percuss all fields of the lung, including breasts, sternum and spinal column

Which of the following techniques used by the nurse to vibrate the lung after percussion is not correct?

• Ask client to inhale deeply and exhale slowly through the nose or pursed lips
• During exhalation tense the wrist muscles and vibrate the hands moving them down, stopping when the client exhales
• Vibrate for five exhalations over one affected lung segment
• Do not encourage coughing as this disrupts the vibrating technique and the nurse will have to restart
• During exhalation tense the wrist muscles and vibrate the hands moving them down, stopping when the client exhales
• Do not encourage coughing as this disrupts the vibrating technique and the nurse will have to restart

Which of the following are correct nursing interventions for clients with endotracheal tubes?

• Assess respiratory status at least every 2 hours
• Place client in a side lying or semi-prone position
• Maintain a cuff pressure of 10-15 mmHg to minimize tracheal tissue necrosis
• Provide oral and nasal care every 2-4 hours
• Assess respiratory status at least every 2 hours
• Place client in a side lying or semi-prone position
• Provide oral and nasal care every 2-4 hours
