The ICU nurse caring for a 2-year-old near drowning victim monitors for what possible complication?

Acute respiratory distress syndrome Factors associated with the development of ARDS include aspiration related to near drowning or vomiting; drug ingestion/overdose; hematologic disorders such as disseminated intravascular coagulation or massive transfusions; direct damage to the lungs through prolonged smoke inhalation or other corrosive substances; localized lung infection; metabolic disorders such as pancreatitis or uremia; shock; trauma such as chest contusions, multiple fractures, or head injury; any major surgery; embolism; and septicemia.

A nurse is caring for a client with a chest tube. If the chest drainage system is accidentally disconnected, what should the nurse plan to do?

Place the end of the chest tube in a container of sterile saline. If a chest drainage system is disconnected, the nurse may place the end of the chest tube in a container of sterile saline or water to prevent air from entering the chest tube, thereby preventing negative respiratory pressure. The nurse should apply an occlusive dressing if the chest tube is pulled out — not if the system is disconnected. The nurse shouldn't clamp the chest tube because clamping increases the risk of tension pneumothorax. The nurse should tape the chest tube securely to prevent it from being disconnected, rather than taping it after it has been disconnected.

The nurse is assessing a client's potential for pulmonary emboli. What finding indicates possible deep vein thrombosis? 1. Decreased urinary output 2. Localized calf tenderness 3. Coolness to lower extremities 4. Pain in the feet

2. Localized calf tenderness

The nurse is caring for a client who has started therapy for tuberculosis. The client demonstrates an understanding of tuberculosis transmission when stating:

"I'll follow airborne precautions until I have three negative sputum specimens." A client is recommended to be maintained on airborne precautions until there are three consecutive acid-fast bacillus (AFB) sputum specimens that are negative. A client with nonresistant tuberculosis is no longer considered contagious when they show clinical evidence of decreased infection, such as significantly decreased coughing and fewer organisms on sputum smears. The medication may not produce negative acid-fast test results for several days. The client won't have a clear chest X-ray for several months after starting treatment. Night sweats are a sign of tuberculosis, but they don't indicate whether the client is contagious.

A nurse is caring for a client with COPD who needs teaching on pursed-lip breathing. Place the steps in order in which the nurse will instruct the client.

"Inhale through your nose." "Slowly count to 3." "Exhale slowly through pursed lips." "Slowly count to 7." Pursed-lip breathing is a technique used to prolong exhalation by propping the airways open and promoting the removal of trapped air and carbon dioxide. The nurse should instruct the client to first inhale through the nose to a slow count of 3. Next, the client should exhale slowly through pursed lips for a count of 7.

A client has been placed on a ventilator, and the spouse begins to cry during the initial visit. What is the best therapeutic statement for the nurse to communicate? "The ventilator gives breaths every timed interval for breathing." "Tell me what you are feeling." "People on the ventilator do not feel pain." "I know this is stressful, but it is the best treatment."

"Tell me what you are feeling."

A nurse recognizes that a client with tuberculosis needs further teaching when the client states:

"The people I have contact with at work should be checked regularly." The client requires additional teaching if he states that coworkers need to be checked regularly. Such casual contacts needn't be tested for tuberculosis. However, a person in close contact with a person who's infectious is at risk and should be checked.

A client at risk for pneumonia has been ordered an influenza vaccine. Which statement from the nurse best explains the rationale for this vaccine?

"Viruses like influenza are the most common cause of pneumonia."

What would the critical care nurse recognize as a condition that may indicate a client's need to have a tracheostomy?

A client requires permanent ventilation. A tracheostomy permits long-term use of mechanical ventilation to prevent aspiration of oral and gastric secretions in the unconscious or paralyzed client. Indications for a tracheostomy do not include a respiratory rate of 10 breaths per minute, symptoms of dyspnea, or respiratory acidosis.

A client with emphysema informs the nurse, "The surgeon will be removing about 30% of my lung so that I will not be so short of breath and will have an improved quality of life." What surgery does the nurse understand the surgeon will perform?

A lung volume reduction. Lung volume reduction is a surgical procedure involving the removal of 20%-30% of a client's lung through a midsternal incision or video thoracoscopy. The diseased lung tissue is identified on a lung perfusion scan. This surgery leads to significant improvements in dyspnea, exercise capacity, quality of life, and survival of a subgroup of people with end-stage emphysema.

Which would be least likely to contribute to a case of hospital-acquired pneumonia?

A nurse washes her hands before beginning client care. HAP occurs when at least one of three conditions exists: host defenses are impaired, inoculums of organisms reach the lower respiratory tract and overwhelm the host's defenses, or a highly virulent organism is present.

A nurse is administering a purified protein derivative (PPD) test to a client. Which statement concerning PPD testing is true?

A positive reaction indicates that the client has been exposed to the disease. A positive reaction means the client has been exposed to TB; it isn't conclusive for the presence of active disease. A positive reaction consists of palpable swelling and induration of 5 to 15 mm. It can be read 48 to 72 hours after the injection. In clients with positive reactions, further studies are usually done to rule out active disease. In immunosuppressed clients, a negative reaction doesn't exclude the presence of active disease.

The public health nurse is administering Mantoux tests to children who are being registered for kindergarten in the community. How should the nurse administer this test?

Administer intradermal injections into each child's inner forearm. The purified protein derivative (PPD) is always injected into the intradermal layer of the inner aspect of the forearm. The subcutaneous and intramuscular routes are not utilized.

A client with severe shortness of breath comes to the emergency department. He tells the emergency department staff that he recently traveled to China for business. Based on his travel history and presentation, the staff suspects severe acute respiratory syndrome (SARS). Which isolation precautions should the staff institute?

Airborne and contact precautions. SARS, a highly contagious viral respiratory illness, is spread by close person-to-person contact. The client should be placed on airborne and contact precautions to prevent the spread of infection. Droplet precautions don't require a negative air pressure room and wouldn't protect the nurse who touches contaminated items in the client's room. Contact precautions alone don't provide adequate protection from airborne particles.

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

Auscultating the lungs for bilateral breath sounds. For the client with an ET tube, the most important nursing action is auscultating the lungs regularly for bilateral breath sounds to ensure proper tube placement and effective oxygen delivery. Although turning the client from side to side every 2 hours, monitoring serial blood gas values every 4 hours, and providing frequent oral hygiene are appropriate actions for this client, they're secondary to ensuring adequate oxygenation.

What assessment method would the nurse use to determine the areas of the lungs that need draining?

Auscultation The nurse should assess breath sounds before doing postural drainage to determine the areas that need draining. Inspection, chest X-rays, and ABG levels are all assessment parameters that give good information about respiratory function but aren't necessary to determine lung areas requiring postural drainage.

A client is being admitted to the preoperative holding area for a thoracotomy. Preoperative teaching includes what?

Correct use of incentive spirometry

A recent immigrant is diagnosed with pulmonary tuberculosis (TB). Which intervention is the most important for the nurse to implement with this client?

Developing a list of people with whom the client has had contact. To lessen the spread of TB, everyone who had contact with the client must undergo a chest X-ray and TB skin test. Testing will help determine if the client infected anyone else.

A patient is admitted to the hospital with pulmonary arterial hypertension. What assessment finding by the nurse is a significant finding for this patient?

Dyspnea. Dyspnea, the main symptom of PH, occurs at first with exertion and eventually at rest. Substernal chest pain also is common. Other signs and symptoms include weakness, fatigue, syncope, occasional hemoptysis, and signs of right-sided heart failure (peripheral edema, ascites, distended neck veins, liver engorgement, crackles, heart murmur). Anorexia and abdominal pain in the right upper quadrant may also occur.

The occupational nurse is completing routine assessments on the employees at a company. What might be revealed by a chest radiograph for a client with occupational lung diseases?

Fibrotic changes in the lungs. For a client with occupational lung diseases, a chest radiograph may reveal fibrotic changes in the lungs. Hemorrhage, lung contusion, and damage to surrounding tissues are possibly caused by trauma due to chest injuries.

A patient arrives in the emergency department after being involved in a motor vehicle accident. The nurse observes paradoxical chest movement when removing the patient's shirt. What does the nurse know that this finding indicates?

Flail chest During inspiration, as the chest expands, the detached part of the rib segment (flail segment) moves in a paradoxical manner (pendelluft movement) in that it is pulled inward during inspiration, reducing the amount of air that can be drawn into the lungs. On expiration, because the intrathoracic pressure exceeds atmospheric pressure, the flail segment bulges outward, impairing the patient's ability to exhale. The mediastinum then shifts back to the affected side (Fig. 23-8). This paradoxical action results in increased dead space, a reduction in alveolar ventilation, and decreased compliance.

A client hospitalized with pneumonia has thick, tenacious secretions. Which intervention should the nurse include when planning this client's care?

For a client with an endotracheal (ET) tube, which nursing action is the most important? Increasing the client's intake of oral or I.V. fluids helps liquefy thick, tenacious secretions, and ensures adequate hydration. Turning the client every 2 hours would help prevent atelectasis, but will not adequately mobilize thick secretions. Elevating the head of the bed would reduce pressure on the diaphragm and ease breathing, but wouldn't help the client with secretions. Maintaining a cool room temperature wouldn't help the client with secretions.

When caring for a client with acute respiratory failure, the nurse should expect to focus on resolving which set of problems?

Hypercapnia, hypoventilation, and hypoxemia The cardinal physiologic abnormalities of acute respiratory failure are hypercapnia, hypoventilation, and hypoxemia. The nurse should focus on resolving these problems.

A client who underwent surgery 12 hours ago has difficulty breathing. He has petechiae over his chest and complains of acute chest pain. What action should the nurse take first?

Initiate oxygen therapy. The client's signs and symptoms suggest pulmonary embolism. Therefore, maintaining respiratory function takes priority. The nurse should first initiate oxygen therapy and then notify the physician immediately. The physician will most likely order an anticoagulant such as heparin or an antithrombolytic to dissolve the thrombus. Analgesics can be administered to decrease pain and anxiety but administering oxygen takes priority. Suctioning typically isn't necessary with pulmonary embolism.

The nurse is educating a patient with COPD about the technique for performing pursed-lip breathing. What does the nurse inform the patient is the importance of using this technique?

It prolongs exhalation. The goal of pursed-lip breathing is to prolong exhalation and increase airway pressure during expiration, thus reducing the amount of trapped air and the amount of airway resistance.

The nursing instructor is teaching students about types of lung cancer. Which type of lung cancer is characterized as fast growing and can arise peripherally?

Large cell carcinoma Large cell carcinoma is a fast-growing tumor that tends to arise peripherally. Bronchoalveolar cell cancer arises from the terminal bronchus and alveoli and usually grows slowly. Adenocarcinoma presents as peripheral masses or nodules and often metastasizes. Squamous cell carcinoma arises from the bronchial epithelium and is more centrally located.

A nurse has performed tracheal suctioning on a client who experienced increasing dyspnea prior to a procedure. When applying the nursing process, how can the nurse best evaluate the outcomes of this intervention?

Measure the client's oxygen saturation. The client's response to suctioning is usually determined by performing chest auscultation and by measuring the client's oxygen saturation. FET, incentive spirometry, and percussion are not normally used as evaluative techniques.

For a client who has a chest tube connected to a closed water-seal drainage system, the nurse should include which action in the care plan?

Measuring and documenting the drainage in the collection chamber The nurse should regularly measure and document the amount of chest tube drainage to detect abnormal drainage patterns, such as may occur with a hemorrhage (if excessive) or a blockage (if decreased). Continuous bubbling in the water-seal chamber indicates a leak in the closed chest drainage system, which must be corrected. The nurse should keep the collection chamber below chest level to allow fluids to drain into it. The nurse shouldn't strip chest tubes because doing so may traumatize the tissue or dislodge the tube.

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 Hypoxemic hypoxia, or hypoxemia, is a decreased oxygen level in the blood (PaO2) resulting in decreased oxygen diffusion into the tissues.

The nurse is caring for a client who is ready to be weaned from the ventilator. In preparing to assist in the collaborative process of weaning, the nurse should anticipate that the weaning of the client will progress in what order?

Removal from the ventilator, tube, and then oxygen The process of withdrawing the client from dependence on the ventilator takes place in three stages: the client is gradually removed from the ventilator, then from the tube, and, finally, oxygen.

A nurse is weaning a client from mechanical ventilation. Which nursing assessment finding indicates the weaning process should be stopped?

Runs of ventricular tachycardia. Ventricular tachycardia indicates that the client isn't tolerating the weaning process. The weaning process should be stopped before lethal ventricular arrhythmias occur. A respiratory rate of 16 breaths/minute and an oxygen saturation of 93% are normal findings. The client's blood pressure remains stable, so the weaning can continue.

You are caring for a client status post lung resection. When assessing your client you find that the bubbling in the water-seal chamber for the chest tubes is more than you expected. What should you check when bubbling in the water-seal chamber is excessive?

See if there are leaks in the system. Bubbling in the water-seal chamber occurs in the early postoperative period. If bubbling is excessive, the nurse checks the system for any kind of leaks. Fluctuation of the fluid in the water-seal chamber is initially present with each respiration. Fluctuations cease if the chest tube is clogged or a kink develops in the tubing. If the suction unit malfunctions, the suction control chamber, not the water-seal chamber, will be affected.

A young man incurred a spontaneous pneumothorax. The physician has just inserted a chest tube and has prescribed suction set at 20 cm of water. The nurse instills the fluid to this level in the appropriate chamber. Mark the level of fluid on the appropriate chamber of the closed drainage system.

Suction control is determined by the height of instilled water in that chamber. The suction control chamber is on the left side. In the middle of the closed drainage system is the water-seal chamber. The drainage chamber is on the right side of the closed drainage system.

A mediastinal shift occurs in which type of chest disorder?

Tension pneumothorax A tension pneumothorax causes the lung to collapse and the heart, the great vessels, and the trachea to shift toward the unaffected side of the chest (mediastinal shift). A traumatic pneumothorax occurs when air escapes from a laceration in the lung itself and enters the pleural space or enters the pleural space through a wound in the chest wall. A simple pneumothorax most commonly occurs as air enters the pleural space through the rupture of a bleb or a bronchopleural fistula. Cardiac tamponade is compression of the heart resulting from fluid or blood within the pericardial sac.

A nurse is giving a speech about communicable diseases of winter to a large group of volunteer women, most of whom are older than 60 years. What preventive measure(s) should the nurse recommend to these women, who are at risk of pneumococcal and influenza infections? Select all that apply. -smoking cessation -vaccinations -prescribed opioids -annual echocardiogram -hand antisepsis

Vaccinations, hand antisepsis, and smoking cessation. A powerful weapon against the spread of communicable disease is effective and frequent handwashing. The pneumococcal vaccine provides specific prevention against pneumococcal pneumonia and other infections caused by S. pneumoniae. The nurse should encourage smoking cessation as a preventative measure against respiratory illness. Annual echocardiograms and prescribed opioids do not reduce the risk of pneumococcal and influenza infections.

The nurse caring for a client with tuberculosis anticipates administering which vitamin with isoniazid (INH) to prevent INH-associated peripheral neuropathy?

Vitamin B6

Which type of ventilator has a preset volume of air to be delivered with each inspiration?

Volume-controlled With volume-controlled ventilation, the volume of air to be delivered with each inspiration is preset. 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 preset pressure, and then cycles off, and expiration occurs passively.

After lobectomy for lung cancer, a client receives a chest tube connected to a disposable chest drainage system. The nurse observes that the drainage system is functioning correctly when she notes tidal movements or fluctuations in which compartment of the system as the client breathes?

Water-seal chamber Fluctuations in the water-seal compartment are called tidal movements and indicate normal function of the system as the pressure in the tubing changes with the client's respirations. The air-leak meter — not chamber — detects air leaking from the pleural space. The collection chamber connects the chest tube from the client to the system. Drainage from the tube drains into and collects in a series of calibrated columns in this chamber. The suction control chamber provides the suction, which can be controlled to provide negative pressure to the chest.

The nurse is caring for a client who works construction with a focus on restoring and demolishing older buildings and who is diagnosed with pneumoconiosis. The nurse understands that the inflammation in the client's lungs is likely due to which substance?

asbestos Asbestosis is caused by inhalation of asbestos dust, which is frequently encountered during construction work, particularly when working with older buildings. Laws restrict asbestos use, but old materials still contain asbestos. Silicosis results from inhalation of silica dust and is seen in workers involved with mining, quarrying, stone cutting, and tunnel building. Inhalation of coal dust and other dusts may cause black lung disease. Pollen may cause an allergic reaction but is unlikely to cause pneumoconiosis.

A physician stated to the nurse that the client has fluid in the pleural space and will need a thoracentesis. The nurse expects the physician to document this fluid as

pleural effusion. Fluid accumulating within the pleural space is called a pleural effusion.
