Chapter 23: Management of Patients with Chest and Lower Respiratory Tract Disorders

Influenza, an annual epidemic in the U.S., creates a significant increase in hospitalizations and an rise in the death rates from pneumonia and cardiovascular disease. Besides death, what is the most serious complication of influenza? cardiovascular disease tracheobronchitis viral pneumonia staphylococcal pneumonia

staphylococcal pneumonia Explanation: Complications include tracheobronchitis, bacterial pneumonia, and cardiovascular disease, however staphylococcal pneumonia is the most serious complication.

Which should a nurse encourage in clients who are at the risk of pneumococcal and influenza infections? Receiving vaccinations Using incentive spirometry Mobilizing early Using prescribed opioids

Receiving vaccinations Explanation: Identifying clients who are at risk for pneumonia provides a means to practice preventive nursing care. The nurse encourages clients at risk of pneumococcal and influenza infections to receive vaccinations against these infections. The nurse should encourage early mobilization as indicated through agency protocol, administer prescribed opioids and sedatives as indicated, and teach or reinforce appropriate technique for incentive spirometry to prevent atelectasis.

A nurse is preparing dietary recommendations for a client with a lung abscess. Which statement would be included in the plan of care? "You must consume a diet rich in protein, such as chicken, fish, and beans." "You must consume a diet low in fat by limiting dairy products and concentrated sweets." "You must consume a diet high in carbohydrates, such as bread, potatoes, and pasta." "You must consume a diet low in calories, such as skim milk, fresh fruits, and vegetables."

"You must consume a diet rich in protein, such as chicken, fish, and beans." Explanation: The nurse encourages a client with a lung abscess to eat a diet that is high in protein and calories in order to ensure proper nutritional intake. A carbohydrate-dense diet or diets with limited fats are not advisable for a client with a lung abscess.

After diagnosing a client with pulmonary tuberculosis, the physician tells family members that they must receive isoniazid (INH [Laniazid]) as prophylaxis against tuberculosis. The client's daughter asks the nurse how long the drug must be taken. What is the usual duration of prophylactic isoniazid therapy? 3 to 5 days 6 to 12 months 2 to 4 months 1 to 3 weeks

6 to 12 months Explanation: Prophylactic isoniazid therapy must continue for 6 to 12 months at a daily dosage of 300 mg. Taking the drug for less than 6 months may not provide adequate protection against tuberculosis

What dietary recommendations should a nurse provide a client with a lung abscess? A diet low in calories A diet rich in protein A diet with limited fat A carbohydrate-dense diet

A diet rich in protein Explanation: For a client with lung abscess, a diet rich in protein and calories is integral because chronic infection is associated with a catabolic state. A carbohydrate-dense diet or diets with limited fat are not advisable for a client with lung abscess.

On auscultation, which finding suggests a right pneumothorax? Inspiratory wheezes in the right thorax Bilateral inspiratory and expiratory crackles Bilateral pleural friction rub Absence of breath sounds in the right thorax

Absence of breath sounds in the right thorax Explanation: In pneumothorax, the alveoli are deflated and no air exchange occurs in the lungs. Therefore, breath sounds in the affected lung field are absent. None of the other options are associated with pneumothorax. Bilateral crackles may result from pulmonary congestion, inspiratory wheezes may signal asthma, and a pleural friction rub may indicate pleural inflammation.

The nurse is collaborating with a community group to develop plans to reduce the incidence of lung cancer in the community. Which of the following would be most effective? Public service announcements on television to promote the use of high-efficiency particulate air (HEPA) filters in homes Legislation that requires homes and apartments be checked for asbestos leakage Advertisements in public places to encourage cigarette smokers to have yearly chest x-rays Classes at community centers to teach about smoking cessation strategies

Classes at community centers to teach about smoking cessation strategies Explanation: Lung cancer is directly correlated with heavy cigarette smoking, and the most effective approach to reducing lung cancer in the community is to help the citizens stop smoking.. The use of HEPA filters can reduce allergens, but they do not prevent lung cancer. Chest x-rays aid in detection of lung cancer but do not prevent it. Exposure to asbestos has been implicated as a risk factor, but cigarette smoking is the major risk factor.

The nurse is assessing a patient who has been admitted with possible ARDS. What findings would distinguish ARDS from cardiogenic pulmonary edema? Elevated white blood count Elevated troponin levels Elevated myoglobin levels Elevated B-type natriuretic peptide (BNP) levels

Elevated B-type natriuretic peptide (BNP) levels Explanation: Common diagnostic tests performed in patients with potential ARDS include plasma brain natriuretic peptide (BNP) levels, echocardiography, and pulmonary artery catheterization. The BNP level is helpful in distinguishing ARDS from cardiogenic pulmonary edema.

Which intervention does a nurse implement for clients with empyema? Encourage breathing exercises Institute droplet precautions Do not allow visitors with respiratory infections Place suspected clients together

Encourage breathing exercises Explanation: The nurse instructs the client in lung-expanding breathing exercises to restore normal respiratory function.

A nurse is caring for a patient diagnosed with empyema. Which of the following interventions does a nurse implement for patients with empyema? Do not allow visitors with respiratory infection. Institute droplet precautions. Encourage breathing exercises. Place suspected patients together.

Encourage breathing exercises. Explanation: The nurse teaches the patient with empyema to do breathing exercises as prescribed. The nurse should institute droplet precautions, isolate suspected and confirmed influenza patients in private rooms, or place suspected and confirmed patients together, and not allow visitors with symptoms of respiratory infection to visit the hospital to prevent outbreaks of influenza from occurring in health care settings.

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

Localized calf tenderness Explanation: If the client were to complain of localized calf tenderness, the nurse would know this is a possible indication of a deep vein thrombosis. The area of tenderness could also be warm to touch. The client's urine output should not be impacted. Pain in the feet is not an indication of possible deep vein thrombosis.

A nurse reading a chart notes that the client had a Mantoux skin test result with no induration and a 1-mm area of ecchymosis. How does the nurse interpret this result? Borderline Positive Negative Uncertain

Negative Explanation: The size of the induration determines the significance of the reaction. A reaction 0-4 mm is not considered significant. A reaction ≥5 mm may be significant in people who are considered to be at risk. An induration ≥10 mm or greater is usually considered significant in people who have normal or mildly impaired immunity.

A client is brought to the emergency department following a motor vehicle accident. Which of the following nursing assessments is significant in diagnosing this client with flail chest? Paradoxical chest movement Chest pain on inspiration Respiratory acidosis Clubbing of fingers and toes

Paradoxical chest movement Explanation: Flail chest occurs when two or more adjacent ribs fracture and results in impairment of chestwall movement. Respiratory acidosis and chest pain are symptoms that can occur with flail chest but is not as significant in the diagnosis as paradoxical chest movement. Clubbing of fingers and toes are sign of prolonged tissue hypoxia.

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. See if the wall suction unit has malfunctioned. See if a kink has developed in the tubing. See if the chest tube is clogged.

See if there are leaks in the system. Explanation: 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.

After 48 hours, a Mantoux test is evaluated. At the site, there is a 10 mm induration. This finding would be considered: Nonreactive Significant Not significant Negative

Significant Explanation: An induration of 10 mm or greater is usually considered significant and reactive in people who have normal or mildly impaired immunity. Erythema without induration is not considered significant.

A patient comes to the clinic with fever, cough, and chest discomfort. The nurse auscultates crackles in the left lower base of the lung and suspects that the patient may have pneumonia. What does the nurse know is the most common organism that causes community-acquired pneumonia?

Streptococcus pneumoniae Explanation: Streptococcus pneumoniae (pneumococcus) is the most common cause of community-acquired pneumonia in people younger than 60 years without comorbidity and in those 60 years and older with comorbidity (Wunderink & Niederman, 2012). S. pneumoniae, a gram-positive organism that resides naturally in the upper respiratory tract, colonizes the upper respiratory tract and can cause disseminated invasive infections, pneumonia and other lower respiratory tract infections, and upper respiratory tract infections such as otitis media and rhinosinusitis. It may occur as a lobar or bronchopneumonic form in patients of any age and may follow a recent respiratory illness.

A client involved in a motor vehicle crash suffered a blunt injury to the chest wall and was brought to the emergency department. The nurse assesses the client for which clinical manifestation that would indicate the presence of a pneumothorax? Sucking sound at the site of injury Bloody, productive cough Decreased respiratory rate Diminished breath sounds

Sucking sound at the site of injury Explanation: Open pneumothorax is one form of traumatic pneumothorax. It occurs when a wound in the chest wall is large enough to allow air to pass freely in and out of the thoracic cavity with each attempted respiration. Because the rush of air through the wound in the chest wall produces a sucking sound, such injuries are termed "sucking chest wounds."

A client is being discharged following pelvic surgery. What would be included in the patient care instructions to prevent the development of a pulmonary embolus? Consume the majority of daily fluid intake prior to bed. Wear tight-fitting clothing. Tense and relax muscles in the lower extremities. Begin estrogen replacement.

Tense and relax muscles in the lower extremities. Explanation: Clients are encouraged to perform passive or active exercises, as tolerated, to prevent a thrombus from forming. Constrictive, tight-fitting clothing is a risk factor for the development of a pulmonary embolism in postoperative clients. Clients at risk for a DVT or a pulmonary embolism are encouraged to drink throughout the day to avoid dehydration. Estrogen replacement is a risk factor for the development of a pulmonary embolism.

During discharge teaching, a nurse is instructing a client about pneumonia. The client demonstrates his understanding of relapse when he states that he must: follow up with the physician in 2 weeks. turn and reposition himself every 2 hours. continue to take antibiotics for the entire 10 days. maintain fluid intake of 40 oz (1,200 ml) per day.

continue to take antibiotics for the entire 10 days. Explanation: The client demonstrates understanding of how to prevent relapse when he states that he must continue taking the antibiotics for the prescribed 10-day course. Although the client should keep the follow-up appointment with the physician and turn and reposition himself frequently, these interventions don't prevent relapse. The client should drink 51 to 101 oz (1,500 to 3,000 ml) per day of clear liquids.

A nurse assesses arterial blood gas results for a patient in acute respiratory failure (ARF). Which results are consistent with this disorder? pH 7.35, PaCO2 48 mm Hg pH 7.28, PaO2 50 mm Hg pH 7.36, PaCO2 32 mm Hg pH 7.46, PaO2 80 mm Hg

pH 7.28, PaO2 50 mm Hg Explanation: ARF is defined as a decrease in arterial oxygen tension (PaO2) to less than 60 mm Hg (hypoxemia) and an increase in arterial carbon dioxide tension (PaCO2) to >50 mm Hg (hypercapnia), with an arterial pH less than 7.35.
