respiratory prepU

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

A patient with COPD requires oxygen administration. What method of delivery does the nurse know would be best for this patient?

A Venturi mask

A patient is brought into the emergency department with carbon monoxide poisoning after escaping a house fire. What should the nurse monitor this patient for?

Anemic hypoxia Anemic hypoxia is a result of decreased effective hemoglobin concentration, which causes a decrease in the oxygen-carrying capacity of the blood. It is rarely accompanied by hypoxemia. Carbon monoxide poisoning, because it reduces the oxygen-carrying capacity of hemoglobin, produces similar effects but is not strictly anemic hypoxia, because hemoglobin levels may be normal.

For a client with an endotracheal (ET) tube, which nursing action is the most important?

Auscultating the lungs for bilateral breath sounds

A nurse is assigned to care for a client with a tracheostomy tube. How can the nurse communicate with this client?

By supplying a magic slate or similar device

A patient is diagnosed with mild obstructive sleep apnea after having a sleep study performed. What treatment modality will be the most effective for this patient?

Continuous positive airway pressure

The nurse is caring for a patient with an endotracheal tube (ET). Which of the following nursing interventions is contraindicated?

Deflating the cuff routinely

The nurse should monitor a client receiving mechanical ventilation for which of the following complications?

Gastrointestinal hemorrhage

The nurse has instructed a patient on how to perform pursed-lip breathing. The nurse recognizes the purpose of this type of breathing is to accomplish which of the following?

Improve oxygen transport, induce a slow, deep breathing pattern, and assist the patient to control breathing

The nurse is assessing a patient with chest tubes connected to a drainage system. What should the first action be when the nurse observes excessive bubbling in the water seal chamber?

Notify the physician.

The nurse is admitting a patient with COPD. The decrease of what substance in the blood gas analysis would indicate to the nurse that the patient is experiencing hypoxemia?

PaO2

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

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

Which of the following statements would not be considered an appropriate intervention for a patient with an ET tube?

Routine cuff deflation is recommended Routine cuff deflation is not recommended because of the increased risk for aspiration and hypoxia. The cuff is deflated before the endotracheal tube is removed. Cuff pressures should be checked every 6 to 8 hours. Humidified oxygen should always be introduced through the tube.

The client is postoperative for a total laryngectomy and has recovered from anesthesia. The client's respirations are 32 breaths/minute, blood pressure is 102/58, and pulse rate is 104 beats/minute. Pulse oximetry is 90%. The client is receiving humidified oxygen. To aid in the client's respiratory status, the nurse places the client in

Semi-Fowlers

A client undergoes a tracheostomy after many failed attempts at weaning him from a mechanical ventilator. Two days after tracheostomy, while the client is being weaned, the nurse detects a mild air leak in the tracheostomy tube cuff. What should the nurse do first?

Suction the client, withdraw residual air from the cuff, and reinflate it.

A nurse is caring for a client who has a tracheostomy tube and who is undergoing mechanical ventilation. The nurse can help prevent tracheal dilation, a complication of tracheostomy tube placement, by:

using the minimal-leak technique with cuff pressure less than 25 cm H2O.

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

Of the following oxygen administration devices, which has the advantage of providing high oxygen concentration?

Non-rebreather mask

A client abruptly sits up in bed, reports having difficulty breathing and has an arterial oxygen saturation of 88%. Which mode of oxygen delivery is most likely to reverse these manifestations?

Nonrebreather mask

A nurse is teaching a client about using an incentive spirometer. Which statement by the nurse is correct?

"Before you do the exercise, I'll give you pain medication if you need it." The nurse should assess the client's pain level before the client does incentive spirometry exercises and administer pain medication as needed. Doing so helps the client take deeper breaths and help prevents atelectasis. The client should breathe in slowly and steadily, and hold his breath for 3 seconds after inhalation. The client should start doing incentive spirometry immediately after surgery and aim to do 10 incentive spirometry breaths every hour.

Which of the following is a potential complication of a low pressure in the endotracheal tube (ET) cuff?

Aspiration pneumonia

A nurse provides care for a client receiving oxygen from a nonrebreather mask. Which nursing intervention has the highest priority?

Assessing the client's respiratory status, orientation, and skin color

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

Assist-control Assist-control ventilation provides full ventilator support by delivering a preset tidal volume and respiratory rate. Intermittent mandatory ventilation (IMV) provides a combination of mechanically assisted breaths and spontaneous breaths. SIMV delivers a preset tidal volume and number of breaths per minute. Between ventilator-delivered breaths, the patient can breathe spontaneously with no assistance from the ventilator for those extra breaths.

The nurse assesses a patient with a heart rate of 42 and a blood pressure of 70/46. What type of hypoxia does the nurse determine this patient is displaying?

Circulatory hypoxia

The nurse is transporting a patient with chest tubes to a treatment room. The chest tube becomes disconnected and falls between the bed rail. What is the priority action by the nurse?

Cut the contaminated tip of the tube and insert a sterile connector and reattach.

A patient with emphysema is placed on continuous oxygen at 2 L/min at home. Why is it important for the nurse to educate the patient and family that they must have No Smoking signs placed on the doors?

Oxygen supports combustion

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.

Which type of ventilator has a pre-sent volume of air to be delivered with each inspiration?

Volume cycled With volume-cycled ventilation, the volume of air to be delivered with each inspiration is present. Negative pressure ventilators exert a negative pressure on the external chest. Time-cycled ventilators terminate or control inspiration after a preset time. When the pressure-cycled ventilator cycles on, it delivers a flow of air (inspiration) until it reaches a present pressure, and then cycles off, and expiration occurs passively.

The nurse is using an in-line suction kit to suction a patient who is intubated and on a mechanical ventilator. What benefits does inline suction have for the patient? (Select all that apply.)

• Decreases hypoxemia • Decreases patient anxiety • Sustains positive end expiratory pressure (PEEP)

The nurse is educating the patient in the use of a mini-nebulizer. What should the nurse encourage the patient to do? (Select all that apply.)

• Hold the breath at the end of inspiration for a few seconds. • Cough frequently. • Frequently evaluate progress.

A patient is being mechanically ventilated with an oral endotracheal tube in place. The nurse observes that the cuff pressure is 25 mm Hg. The nurse is aware of what complications that can be caused by this pressure? (Select all that apply.)

• Pressure necrosis • Tracheal bleeding • Tracheal ischemia

A client with COPD has been receiving oxygen therapy for an extended period. What symptoms would be indicators that the client is experiencing oxygen toxicity? Select all that apply.

• Substernal pain • Dyspnea • Fatigue
