Respiratory chapter 21 exams 2

The nurse is preparing to assist the health care provider to remove a client's chest tube. Which instruction will the nurse correctly give to the client?

"When the tube is being removed, take a deep breath, exhale, and bear down."

Which range of water pressure within the endotracheal tube cuff is believed to prevent both injury and aspiration?

15 to 20 mm Hg

A client with a respiratory condition is receiving oxygen therapy. While assessing the client's PaO2, the nurse knows that the therapy has been effective based on which of the following readings?

84 mm Hg

Which ventilator mode provides full ventilatory support by delivering a present tidal volume and respiratory rate?

Assist control

The nurse hears the patient's ventilator alarm sound and attempts to find the cause. What is the priority action of the nurse when the cause of the alarm is not able to be determined?

Disconnect the patient from the ventilator and manually ventilate the patient with a manual resuscitation bag until the problem is resolved.

A nurse is caring for a client who has a tracheostomy and temperature of 103° F (39.4° C). Which intervention will most likely lower the client's arterial blood oxygen saturation?

Endotracheal suctioning

Which type of oxygen therapy includes the administration of oxygen at pressure greater than atmospheric pressure?

Hyperbaric

A young male client has muscular dystrophy. His PaO2 is 42 mm Hg with a FiO2 of 80%. Which of the following treatments would be least invasive and most appropriate for this client?

Negative-pressure ventilator

Which oxygen administration device has the advantage of providing a high oxygen concentration?

Nonrebreathing mask

Positive end-expiratory pressure (PEEP) therapy has which effect on the heart?

Reduced cardiac output

A client is prescribed postural drainage because secretions are accumulating in the upper lobes of the lungs. The nurse instructs the client to:

Take prescribed albuterol (Ventolin) before performing postural drainage.

A client in acute respiratory distress is brought to the emergency department. After endotracheal (ET) intubation and initiation of mechanical ventilation, the client is transferred to the intensive care unit. Before suctioning the ET tube, the nurse hyperventilates and hyperoxygenates the client. What is the rationale for these interventions?

They help prevent cardiac arrhythmias.

A client who must begin oxygen therapy asks the nurse why this treatment is necessary? What would the nurse identify as the goals of oxygen therapy? Select all that apply.

To provide adequate transport of oxygen in the blood To reduce stress on the myocardium To decrease the work of breathing

Which of the following are indicators that a client is ready to be weaned from a ventilator? Select all that apply.

Vital capacity of 13 mL/kg Tidal volume of 8.5 mL/kg PaO2 of 64 mm Hg

Hyperbaric oxygen therapy increases the blood's capacity to carry and deliver oxygen to compromised tissues. This therapy may be used for a client with:

a compromised skin graft

After undergoing a left thoracotomy, a client has a chest tube in place. When caring for this client, the nurse must:

encourage coughing and deep breathing.

A nurse is caring for a client who was intubated because of respiratory failure. The client is now receiving mechanical ventilation with a preset tidal volume and number of breaths each minute. The client has the ability to breathe spontaneously between the ventilator breaths with no ventilator assistance. The nurse should document the ventilator setting as:

synchronized intermittent mandatory ventilation (SIMV).

The nurse is teaching a postoperative client who had a coronary artery bypass graft about using the incentive spirometer. The nurse instructs the client to perform the exercise in the following order:

Sit in an upright position. Place the mouthpiece of the spirometer in the mouth. Breathe air in through the mouth. Hold breath for about 3 seconds. Exhale air slowly through the mouth.

A client is being mechanically ventilated in the ICU. The ventilator alarms begin to sound. The nurse should complete which action first?

Troubleshoot to identify the malfunction.

The nurse is caring for a client in the ICU who required emergent endotracheal (ET) intubation with mechanical ventilation. The nurse receives an order to obtain arterial blood gases (ABGs) after the procedure. The nurse recognizes that ABGs should be obtained how long after mechanical ventilation is initiated?

20 minutes

A client has been receiving 100% oxygen therapy by way of a nonrebreather mask for several days. Now the client complains of tingling in the fingers and shortness of breath, is extremely restless, and describes a pain beneath the breastbone. What should the nurse suspect?

Oxygen toxicity

The nurse is preparing to perform tracheostomy care for a client with a newly inserted tracheostomy tube. Which action, if preformed by the nurse, indicates the need for further review of the procedure?

Places clean tracheostomy ties then removes soiled ties after the new ties are in place

A client with myasthenia gravis is receiving continuous mechanical ventilation. When the high-pressure alarm on the ventilator sounds, what should the nurse do?

Suction the client's artificial airway.
