Chapter 27: Lower Respiratory Problems

When planning care for a patient at risk for pulmonary embolism, the nurse prioritizes a. maintaining the patient on bed rest. b. using sequential compression devices. c. encouraging the patient to cough and deep breathe. d. teaching the patient how to use the incentive spirometer.

13. Correct answer: b Rationale: Deep vein thrombosis (DVT) is the primary cause of pulmonary embolism. Preventing DVT with the use of sequential compression devices, early ambulation, and prophylactic use of anticoagulant medications would thus be a priority nursing intervention

Acute respiratory failure (ARF) occurs when oxygen tension (PaO2) falls to less than __________ mm Hg (hypoxemia) and carbon dioxide tension (PaCO2) rises to greater than __________ mm Hg (hypercapnia). a) 50 and 50 b) 75 and75 c) 80 and 80 d) 60 and 60

50 and 50 Acute respiratory failure (ARF) is classified as hypoxemic (decrease in arterial oxygen tension [PaO2] to <50 mm Hg on room air) and or hypercapnic (increase in arterial carbon dioxide tension [PaCO2] to >50 mm Hg with an arterial pH of <7.35).

*The nurse administers prescribed therapies for a patient with cor pulmonale and right-sided heart failure. Which assessment could be used to evaluate the effectiveness of the therapies? a. Observe for distended neck veins. b. Auscultate for crackles in the lungs. c. Palpate for heaves or thrills over the heart. d. Monitor for elevated white blood cell count.

A (Cor pulmonale is right ventricular failure caused by pulmonary hypertension, so clinical manifestations of right ventricular failure such as peripheral edema, jugular venous distention, and right upper-quadrant abdominal tenderness would be expected. Crackles in the lungs are likely to be heard with left-sided heart failure. Findings in cor pulmonale include evidence of right ventricular hypertrophy on electrocardiography and an increase in intensity of the second heart sound. Heaves or thrills are not common with cor pulmonale. White blood count elevation might indicate infection but is not expected with cor pulmonale.)

*A patient experiences a chest wall contusion as a result of being struck in the chest with a baseball bat. The emergency department nurse would be most concerned if which finding is observed during the initial assessment? a. Paradoxical chest movement c. Heart rate of 110 beats/minute b. Complaint of chest wall pain d. Large bruised area on the chest

A (Paradoxical chest movement indicates that the patient may have flail chest, which can severely compromise gas exchange and can rapidly lead to hypoxemia. Chest wall pain, a slightly elevated pulse rate, and chest bruising all require further assessment or intervention, but the priority concern is poor gas exchange.)

A 70-year-old woman with chronic heart failure and atrial fibrillation asks the nurse why warfarin (Coumadin) has been prescribed for her to continue at home. Which response by the nurse is accurate? A "The medication prevents blood clots from forming in your heart." B "The medication dissolves clots that develop in your coronary arteries." C "The medication reduces clotting by decreasing serum potassium levels." D "The medication increases your heart rate so that clots do not form in your heart."

A "The medication prevents blood clots from forming in your heart." Chronic heart failure causes enlargement of the chambers of the heart and an altered electrical pathway, especially in the atria. When numerous sites in the atria fire spontaneously and rapidly, atrial fibrillation occurs. Atrial fibrillation promotes thrombus formation within the atria with an increased risk of stroke and requires treatment with cardioversion, antidysrhythmics, and/or anticoagulants. Warfarin is an anticoagulant that interferes with hepatic synthesis of vitamin K-dependent clotting factors.

The perioperative nurse is writing a care plan for a patient who has returned from surgery 2 hours prior. Which measure should the nurse implement to most decrease the patients risk of developing pulmonary emboli (PE)? A) Early ambulation B) Increased dietary intake of protein C) Maintaining the patient in a supine position D) Administering aspirin with warfarin

A) Early ambulation For patients at risk for PE, the most effective approach for prevention is to prevent deep vein thrombosis. Active leg exercises to avoid venous stasis, early ambulation, and use of elastic compression stocking are general preventive measures. The patient does not require increased dietary intake of protein directly related to prevention of PE, although it will assist in wound healing during the postoperative period. The patient should not be maintained in one position, but frequently repositioned, unless contraindicated by the surgical procedure. Aspirin should never be administered with warfarin because it will increase the patients risk for bleeding.

The nurse is assessing an adult patient following a motor vehicle accident. The nurse observes that the patient has an increased use of accessory muscles and is complaining of chest pain and shortness of breath. The nurse should recognize the possibility of what condition? A) Pneumothorax B) Anxiety C) Acute bronchitis D) Aspiration

A) Pneumothorax If the pneumothorax is large and the lung collapses totally, acute respiratory distress occurs. The patient is anxious, has dyspnea and air hunger, has increased use of the accessory muscles, and may develop central cyanosis from severe hypoxemia. These symptoms are not definitive of pneumothorax, but because of the patients recent trauma they are inconsistent with anxiety, bronchitis, or aspiration.

A patient has been brought to the ED by the paramedics. The patient is suspected of having ARDS. What intervention should the nurse first anticipate? A) Preparing to assist with intubating the patient B) Setting up oxygen at 5 L/minute by nasal cannula C) Performing deep suctioning D) Setting up a nebulizer to administer corticosteroids

A) Preparing to assist with intubating the patient A patient who has ARDS usually requires intubation and mechanical ventilation. Oxygen by nasal cannula would likely be insufficient. Deep suctioning and nebulizers may be indicated, but the priority is to secure the airway.

*The nurse notes new onset confusion in an older patient who is normally alert and oriented. In which order should the nurse take the following actions? (Put a comma and a space between each answer choice [A, B, C, D].) a. Obtain the O2 saturation. b. Check the patient's pulse rate. c. Document the change in status. d. Notify the health care provider.

A, B, D, C (Assessment for physiologic causes of new onset confusion such as pneumonia, infection, or perfusion problems should be the first action by the nurse. Airway and oxygenation should be assessed first, then circulation. After assessing the patient, the nurse should notify the health care provider. Finally, documentation of the assessments and care should be done.)

You are an ICU nurse caring for a client who was admitted with a diagnosis of smoke inhalation. You know that this client is at increased risk for which of the following? a) Bronchitis b) Tracheobronchitis c) Lung cancer d) Acute respiratory distress syndrome

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. Smoke inhalation does not increase the risk for lung cancer, bronchitis, and tracheobronchitis.

*The nurse monitors a patient in the emergency department after chest tube placement for a hemopneumothorax. The nurse is most concerned if which assessment finding is observed? a. A large air leak in the water-seal chamber b. 400 mL of blood in the collection chamber c. Complaint of pain with each deep inspiration d. Subcutaneous emphysema at the insertion site

B (The large amount of blood may indicate that the patient is in danger of developing hypovolemic shock. An air leak would be expected immediately after chest tube placement for a pneumothorax. Initially, brisk bubbling of air occurs in this chamber when a pneumothorax is evacuated. The pain should be treated but is not as urgent a concern as the possibility of continued hemorrhage. Subcutaneous emphysema should be monitored but is not unusual in a patient with pneumothorax. A small amount of subcutaneous air is harmless and will be reabsorbed.)

*An hour after a thoracotomy, a patient complains of incisional pain at a level 7 (based on 0 to 10 scale) and has decreased left-sided breath sounds. The pleural drainage system has 100 mL of bloody drainage and a large air leak. Which action should the nurse take? a. Clamp the chest tube in two places. b. Administer the prescribed morphine. c. Milk the chest tube to remove any clots. d. Assist the patient with incentive spirometry.

B (Treat the pain. The patient is unlikely to take deep breaths or cough until the pain level is lower. A chest tube output of 100 mL is not unusual in the first hour after thoracotomy. Milking or stripping chest tubes is no longer recommended because these practices can dangerously increase intrapleural pressures and damage lung tissues. Position tubing so that drainage flows freely to negate need for milking or stripping. An air leak is expected in the initial postoperative period after thoracotomy. Clamping the chest tube is not indicated and may lead to dangerous development of a tension pneumothorax.)

The home care nurse visits a 73-year-old Hispanic woman with chronic heart failure. Which clinical manifestations, if assessed by the nurse, would indicate acute decompensated heart failure (pulmonary edema)? A Fatigue, orthopnea, and dependent edema B Severe dyspnea and blood-streaked, frothy sputum C Temperature is 100.4o F and pulse is 102 beats/minute D Respirations 26 breaths/minute despite oxygen by nasal cannula

B Severe dyspnea and blood-streaked, frothy sputum Clinical manifestations of pulmonary edema include anxiety, pallor, cyanosis, clammy and cold skin, severe dyspnea, use of accessory muscles of respiration, a respiratory rate > 30 breaths per minute, orthopnea, wheezing, and coughing with the production of frothy, blood-tinged sputum. Auscultation of the lungs may reveal crackles, wheezes, and rhonchi throughout the lungs. The heart rate is rapid, and blood pressure may be elevated or decreased.

The nurse is caring for a patient suspected of having ARDS. What is the most likely diagnostic test ordered in the early stages of this disease to differentiate the patients symptoms from those of a cardiac etiology? A) Carboxyhemoglobin level B) Brain natriuretic peptide (BNP) level C) C-reactive protein (CRP) level D) Complete blood count

B) Brain natriuretic peptide (BNP) level Common diagnostic tests performed for 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. The carboxyhemoglobin level will be increased in a client with an inhalation injury, which commonly progresses into ARDS. CRP and CBC levels do not help differentiate from a cardiac problem.

A patient is brought to the ED by ambulance after a motor vehicle accident in which the patient received blunt trauma to the chest. The patient is in acute respiratory failure, is intubated, and is transferred to the ICU. What parameters of care should the nurse monitor most closely? Select all that apply. A) Coping B) Level of consciousness C) Oral intake D) Arterial blood gases E) Vital signs

B) Level of consciousness D) Arterial blood gases E) Vital signs Patients are usually treated in the ICU. The nurse assesses the patients respiratory status by monitoring the level of responsiveness, ABGs, pulse oximetry, and vital signs. Oral intake and coping are not immediate priorities during the acute stage of treatment, but would become more important later during recovery.

A patient is receiving thrombolytic therapy for the treatment of pulmonary emboli. What is the best way for the nurse to assess the patients oxygenation status at the bedside? A) Obtain serial ABG samples. B) Monitor pulse oximetry readings. C) Test pulmonary function. D) Monitor incentive spirometry volumes.

B) Monitor pulse oximetry readings. The nurse assesses the patient with pulmonary emboli frequently for signs of hypoxemia and monitors the pulse oximetry values to evaluate the effectiveness of the oxygen therapy. ABGs are accurate indicators of oxygenation status, but are not analyzed at the bedside. PFTs and incentive spirometry volumes do not accurately reveal oxygenation status.

A firefighter was trapped in a fire and is admitted to the ICU for smoke inhalation. After 12 hours, the firefighter is exhibiting signs of ARDS and is intubated. What other supportive measures are initiated in a patient with ARDS? A) Psychological counseling B) Nutritional support C) High-protein oral diet D) Occupational therapy

B) Nutritional support Aggressive, supportive care must be provided to compensate for the severe respiratory dysfunction. This supportive therapy almost always includes intubation and mechanical ventilation. In addition, circulatory support, adequate fluid volume, and nutritional support are important. Oral intake is contraindicated by intubation. Counseling and occupational therapy would not be priorities during the acute stage of ARDS.

A patient who involved in a workplace accident suffered a penetrating wound of the chest that led to acute respiratory failure. What goal of treatment should the care team prioritize when planning this patients care? A) Facilitation of long-term intubation B) Restoration of adequate gas exchange C) Attainment of effective coping D) Self-management of oxygen therapy

B) Restoration of adequate gas exchange The objectives of treatment are to correct the underlying cause of respiratory failure and to restore adequate gas exchange in the lung. This is priority over coping and self-care. Long-term ventilation may or may not be indicated.

*The nurse is caring for a patient with idiopathic pulmonary arterial hypertension (IPAH). Which assessment information requires the most immediate action by the nurse? a. The O2 saturation is 90%. b. The blood pressure is 98/56 mm Hg. c. The epoprostenol (Flolan) infusion is disconnected. d. The international normalized ratio (INR) is prolonged.

C (The half-life of this drug is 6 minutes, so the nurse will need to restart the infusion as soon as possible to prevent rapid clinical deterioration. The other data also indicate a need for ongoing monitoring or intervention, but the priority action is to reconnect the infusion.)

The nurse prepares to administer digoxin (Lanoxin) 0.125 mg to an 82-year-old man admitted with influenza and a history of chronic heart failure. What should the nurse assess before giving the medication? A Prothrombin time B Urine specific gravity C Serum potassium level D Hemoglobin and hematocrit

C Serum potassium level Serum potassium should be monitored because hypokalemia increases the risk for digoxin toxicity. Changes in prothrombin time, urine specific gravity, and hemoglobin or hematocrit would not require holding the digoxin dose.

A patient presents to the ED stating she was in a boating accident about 3 hours ago. Now the patient has complaints of headache, fatigue, and the feeling that he just cant breathe enough. The nurse notes that the patient is restless and tachycardic with an elevated blood pressure. This patient may be in the early stages of what respiratory problem? A) Pneumoconiosis B) Pleural effusion C) Acute respiratory failure D) Pneumonia

C) Acute respiratory failure Early signs of acute respiratory failure are those associated with impaired oxygenation and may include restlessness, fatigue, headache, dyspnea, air hunger, tachycardia, and increased blood pressure. As the hypoxemia progresses, more obvious signs may be present, including confusion, lethargy, tachycardia, tachypnea, central cyanosis, diaphoresis, and, finally, respiratory arrest. Pneumonia is infectious and would not result from trauma. Pneumoconiosis results from exposure to occupational toxins. A pleural effusion does not cause this constellation of symptoms.

The nurse is providing discharge teaching for a patient who developed a pulmonary embolism after total knee surgery. The patient has been converted from heparin to sodium warfarin (Coumadin) anticoagulant therapy. What should the nurse teach the client? A) Coumadin will continue to break up the clot over a period of weeks B) Coumadin must be taken concurrent with ASA to achieve anticoagulation. C) Anticoagulant therapy usually lasts between 3 and 6 months. D) He should take a vitamin supplement containing vitamin K .

C) Anticoagulant therapy usually lasts between 3 and 6 months. Anticoagulant therapy prevents further clot formation, but cannot be used to dissolve a clot. The therapy continues for approximately 3 to 6 months and is not combined with ASA. Vitamin K reverses the effect of anticoagulant therapy and normally should not be taken

The nurse is caring for a patient in the ICU admitted with ARDS after exposure to toxic fumes from a hazardous spill at work. The patient has become hypotensive. What is the cause of this complication to the ARDS treatment? A) Pulmonary hypotension due to decreased cardiac output B) Severe and progressive pulmonary hypertension C) Hypovolemia secondary to leakage of fluid into the interstitial spaces D) Increased cardiac output from high levels of PEEP therapy

C) Hypovolemia secondary to leakage of fluid into the interstitial spaces Systemic hypotension may occur in ARDS as a result of hypovolemia secondary to leakage of fluid into the interstitial spaces and depressed cardiac output from high levels of PEEP therapy. Pulmonary hypertension, not pulmonary hypotension, sometimes is a complication of ARDS, but it is not the cause of the patient becoming hypotensive.

A patient with a gunshot wound to the right side of the chest arrives in the emergency department exhibiting severe shortness of breath with decreased breath sounds on the right side of the chest. Which action should the nurse take immediately? Cover the chest wound with a nonporous dressing taped on three sides. Pack the chest wound with sterile saline soaked gauze and tape securely. Stabilize the chest wall with tape and initiate positive pressure ventilation. Apply a pressure dressing over the wound to prevent excessive loss of blood.

Cover the chest wound with a nonporous dressing taped on three sides. The patient has a sucking chest wound (open pneumothorax). Air enters the pleural space through the chest wall during inspiration. Emergency treatment consists of covering the wound with an occlusive dressing that is secured on three sides. During inspiration, the dressing pulls against the wound, preventing air from entering the pleural space. During expiration, the dressing is pushed out and air escapes through the wound and from under the dressing.

*A patient with a possible pulmonary embolism complains of chest pain and difficulty breathing. The nurse finds a heart rate of 142 beats/min, blood pressure of 100/60 mm Hg, and respirations of 42 breaths/min. Which action should the nurse take first? a. Administer anticoagulant drug therapy. b. Notify the patient's health care provider. c. Prepare patient for a spiral computed tomography (CT). d. Elevate the head of the bed to a semi-Fowler's position.

D (The patient has symptoms consistent with a pulmonary embolism (PE). Elevating the head of the bed will improve ventilation and gas exchange. The other actions can be accomplished after the head is elevated (and O2 is started). A spiral CT may be ordered by the health care provider to identify PE. Anticoagulants may be ordered after confirmation of the diagnosis of PE.)

*When assessing a patient who has just arrived after an automobile accident, the emergency department nurse notes tachycardia and absent breath sounds over the right lung. For which intervention will the nurse prepare the patient? a. Emergency pericardiocentesis c. Bronchodilator administration b. Stabilization of the chest wall d. Chest tube connected to suction

D (The patient's history and absent breath sounds suggest a right-sided pneumothorax or hemothorax, which will require treatment with a chest tube and drainage to suction. The other therapies would be appropriate for an acute asthma attack, flail chest, or cardiac tamponade, but the patient's clinical manifestations are not consistent with these problems.)

The nurse is administering a dose of digoxin (Lanoxin) to a patient with heart failure (HF). The nurse would become concerned with the possibility of digitalis toxicity if the patient reported which symptom(s)? A Muscle aches B Constipation C Pounding headache D Anorexia and nausea

D Anorexia and nausea Anorexia, nausea, vomiting, blurred or yellow vision, and cardiac dysrhythmias are all signs of digitalis toxicity. The nurse would become concerned and notify the health care provider if the patient exhibited any of these symptoms.

A patient in the ICU is status post embolectomy after a pulmonary embolus. What assessment parameter does the nurse monitor most closely on a patient who is postoperative following an embolectomy? A) Pupillary response B) Pressure in the vena cava C) White blood cell differential D) Pulmonary arterial pressure

D) Pulmonary arterial pressure If the patient has undergone surgical embolectomy, the nurse measures the patients pulmonary arterial pressure and urinary output. Pressure is not monitored in a patients vena cava. White cell levels and pupillary responses would be monitored, but not to the extent of the patients pulmonary arterial pressure.

The home care nurse is monitoring a patient discharged home after resolution of a pulmonary embolus. For what potential complication would the home care nurse be most closely monitoring this patient? A) Signs and symptoms of pulmonary infection B) Swallowing ability and signs of aspiration C) Activity level and role performance D) Residual effects of compromised oxygenation

D) Residual effects of compromised oxygenation The home care nurse should monitor the patient for residual effects of the PE, which involved a severe disruption in respiration and oxygenation. PE has a noninfectious etiology; pneumonia is not impossible, but it is a less likely sequela. Swallowing ability is unlikely to be affected; activity level is important, but secondary to the effects of deoxygenation.

A patient is diagnosed with pulmonary edema. The nurse anticipates a prescription for which type of medication? Diuretic Vasodilator β-adrenergic blocker Angiotensin-converting enzyme (ACE) inhibitor

Diuretic

The nurse is caring for an older adult patient who underwent a left total knee arthroplasty. On the third postoperative day, the patient reports shortness of breath, slight chest pain, and that "something is wrong." Temperature is 98.4°F, blood pressure is 130/88 mm Hg, respirations are 36 breaths/min, and oxygen saturation is 91% on room air. What is the priority nursing action? Notify the health care provider. Administer a nitroglycerin tablet sublingually. Conduct a thorough assessment of the chest pain. Sit the patient up in bed as tolerated and apply oxygen.

Sit the patient up in bed as tolerated and apply oxygen. The patient's clinical picture is most likely pulmonary embolus, and the first action the nurse takes should be to assist with the patient's respirations. For this reason, the nurse should sit the patient up as tolerated and apply oxygen before notifying the physician. The nitroglycerin tablet would not be helpful, and the oxygenation status is a bigger problem than the slight chest pain at this time.

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

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

The nurse instructs a patient with a pulmonary embolism about administering enoxaparin after discharge. Which statement by the patient indicates understanding about the instructions? "I need to take this medicine with meals." "The medicine will be prescribed for 10 days." "I will inject this medicine into my upper arm." "The medicine will dissolve the clot in my lung."

"The medicine will be prescribed for 10 days." Enoxaparin is a low-molecular-weight heparin that is administered for 10 to 14 days and prevents future clotting but does not dissolve existing clots. Fibrinolytic agents (e.g., tissue plasminogen activator or alteplase) dissolve an existing clot. Enoxaparin is administered subcutaneously by injection into the abdomen.

The nurse is caring for a patient developing pulmonary edema. What respiratory rate does the nurse anticipate when assessing this patient? 10 to 14 breaths/minute 16 to 20 breaths/minute 22 to 28 breaths/minute 32 to 36 breaths/minute

32 to 36 breaths/minute

The ICU nurse caring for a 2-year-old near drowning victim monitors for what possible complication? a) Atelectasis b) Acute respiratory distress syndrome c) Metabolic alkalosis d) Respiratory acidosis

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. Options A, C and D are incorrect.

Which of the following is a potential complication of a low pressure in the endotracheal cuff? a) Pressure necrosis b) Aspiration pneumonia c) Tracheal ischemia d) Tracheal bleeding

Aspiration pneumonia Low pressure in the cuff can increase the risk for aspiration pneumonia. High cuff pressure can cause tracheal bleeding, ischemia, and pressure necrosis.

*A patient who has a right-sided chest tube after a thoracotomy has continuous bubbling in the suction-control chamber of the collection device. Which action by the nurse is appropriate? a. Adjust the dial on the wall regulator. b. Continue to monitor the collection device. c. Document the presence of a large air leak. d. Notify the surgeon of a possible pneumothorax

B (Continuous bubbling is expected in the suction-control chamber and indicates that the suction-control chamber is connected to suction. An air leak would be detected in the water-seal chamber. There is no evidence of pneumothorax. Increasing or decreasing the vacuum source will not adjust the suction pressure. The amount of suction applied is regulated by the amount of water in this chamber and not by the amount of suction applied to the system.)

*The nurse receives change-of-shift report on the following four patients. Which patient should the nurse assess first? a. A 23-yr-old patient with cystic fibrosis who has pulmonary function testing scheduled b. A 46-yr-old patient on bed rest who is complaining of sudden onset of shortness of breath c. A 77-yr-old patient with tuberculosis (TB) who has four medications due in 15 minutes d. A 35-yr-old patient who was admitted with pneumonia and has a temperature of 100.2° F (37.8° C)

B (Patients on bed rest who are immobile are at high risk for deep vein thrombosis (DVT). Sudden onset of shortness of breath in a patient with a DVT suggests a pulmonary embolism and requires immediate assessment and action such as O2 administration. The other patients should also be assessed as soon as possible, but there is no indication that they may need immediate action to prevent clinical deterioration.)

*A patient with idiopathic pulmonary arterial hypertension (IPAH) is receiving nifedipine (Procardia). Which assessment would best indicate to the nurse that the patient's condition is improving? a. Patient's chest x-ray indicates clear lung fields. b. Heart rate is between 60 and 100 beats/minute. c. Patient reports a decrease in exertional dyspnea. d. Blood pressure (BP) is less than 140/90 mm Hg.

C (Because a major symptom of IPAH is exertional dyspnea, an improvement in this symptom would indicate that the medication was effective. Nifedipine will affect BP and heart rate, but these parameters would not be used to monitor the effectiveness of therapy for a patient with IPAH. The chest x-ray will show clear lung fields even if the therapy is not effective.)

One week after a thoracotomy, a patient with chest tubes (CTs) to water-seal drainage has an air leak into the closed chest drainage system (CDS). Which patient assessment warrants follow-up nursing actions? Water-seal chamber has 5 cm of water. No new drainage in collection chamber Chest tube with a loose-fitting dressing Small pneumothorax at CT insertion site

Chest tube with a loose-fitting dressing If the dressing at the CT insertion site is loose, an air leak will occur and will need to be sealed. The water-seal chamber usually has 2 cm of water, but having more water will not contribute to an air leak, and it should not be drained from the CDS. No new drainage does not indicate an air leak but may indicate the CT is no longer needed. If there is a pneumothorax, the chest tube should remove the air.

The nurse notes tidaling of the water level in the tube submerged in the water-seal chamber in a patient with closed chest tube drainage. The nurse should a. continue to monitor the patient. b. check all connections for a leak in the system. c. lower the drainage collector further from the chest. d. clamp the tubing at progressively distal points away from the patient until the tidaling stops.

Correct answer: a Rationale: Tidaling is a normal fluctuation of the water in the water-seal chamber of a chest tube. Tidaling reflects the intrapleural pressure during inspiration and expiration.

What is the reason for chest tubes after thoracic surgery? a) Draining secretions, air, and blood from the thoracic cavity is necessary. b) Chest tubes allow air into the pleural space. c) Chest tubes indicate when the lungs have re-expanded by ceasing to bubble. d) Draining secretions and blood while allowing air to remain in the thoracic cavity is necessary.

Draining secretions, air, and blood from the thoracic cavity is necessary. After thoracic surgery, draining secretions, air, and blood from the thoracic cavity is necessary to allow the lungs to expand. This makes options B, C, and D are incorrect.

A patient is admitted to the hospital with pulmonary arterial hypertension. What assessment finding by the nurse is a significant finding for this patient? a) Syncope b) Hypertension c) Ascites d) Dyspnea

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 rightsided 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.

When caring for a client with acute respiratory failure, the nurse should expect to focus on resolving which set of problems? a) Hyperventilation, hypertension, and hypocapnia b) Hyperoxemia, hypocapnia, and hyperventilation c) Hypotension, hyperoxemia, and hypercapnia d) Hypercapnia, hypoventilation, and hypoxemia

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.

The nurse is caring for a patient with an alteration in airway clearance. What nursing actions would be a priority to promote airway clearance (select all that apply.)? Select all that apply. Maintain adequate fluid intake. Maintain a 30-degree elevation. Splint the chest when coughing. Maintain a semi-Fowler's position. Instruct patient to cough at end of exhalation.

Maintain adequate fluid intake, Splint the chest when coughing, Instruct patient to cough at end of exhalation. Maintaining adequate fluid intake liquefies secretions, allowing easier expectoration. The nurse should instruct the patient to splint the chest while coughing. This will reduce discomfort and allow for a more effective cough. Coughing at the end of exhalation promotes a more effective cough. The patient should be positioned in an upright sitting position (high Fowler's) with head slightly flexed.

The nurse is admitting a patient with a diagnosis of pulmonary embolism. What risk factors is a priority for the nurse to assess (select all that apply.)? Select all that apply. Obesity Pneumonia Malignancy Cigarette smoking Prolonged air travel

Obesity, malignancy, cigarette smoking, prolonged air travel, An increased risk of pulmonary embolism is associated with obesity, malignancy, heavy cigarette smoking, and prolonged air travel with reduced mobility. Other risk factors include deep vein thrombosis, immobilization, and surgery within the previous 3 months, oral contraceptives and hormone therapy, heart failure, pregnancy, and clotting disorders.

You are assessing a client's potential for pulmonary emboli. What finding indicates possible deep vein thrombosis? a) Negative Homan's sign b) Pain in the calf c) Inability to dorsiflex d) Pain in the feet

Pain in the calf When assessing the client's potential for pulmonary emboli, the nurse tests for a positive Homan's sign. The client lies on his or her back and lifts his or her leg and his or her foot. If the client reports calf pain (positive Homan's sign) during this maneuver, he or she may have a deep vein thrombosis.

Which of the following actions is most appropriate for the nurse to take when the patient demonstrates subcutaneous emphysema along the suture line or chest dressing 2 hours after chest surgery? a) Measure the patient's pulse oximetry b) Record the observation c) Apply a compression dressing to the area d) Report the finding to the physician immediately

Record the observation Subcutaneous emphysema occurs after chest surgery as the air that is located within the pleural cavity is expelled through the tissue opening created by the surgical procedure. Subcutaneous emphysema is a typical postoperative finding in the patient after chest surgery. Subcutaneous emphysema is absorbed by the body spontaneously after the underlying leak is treated or halted. Subcutaneous emphysema results from air entering the tissue planes.

A 67-year-old female client is being discharged postoperative following pelvic surgery. The patient care instructions to prevent the development of a pulmonary embolus would include which of the following? a) Wear tight-fitting clothing. b) Consume majority of fluid intake prior to bed. c) Begin estrogen replacement. d) Tense and relax muscles in lower extremities.

Tense and relax muscles in lower extremities. Clients are encouraged to perform passive or active exercises, as tolerated, to prevent the development of 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.
