Pulmonary Quiz
A client with a pulmonary embolus has the following arterial blood gas (ABG) values: pH, 7.49; partial pressure of arterial oxygen (PaO2), 60 mm Hg; partial pressure of arterial carbon dioxide (PaCO2), 30 mm Hg; bicarbonate (HCO3-) 25 mEq/L. What should the nurse do first?
Administer oxygen by nasal cannula as ordered. When a pulmonary embolus places a client at risk for oxygen deprivation, the body compensates by hyperventilating. This causes respiratory alkalosis, as reflected in the client's ABG values. However, the most significant ABG value is the PaO2 value of 60 mm Hg, which indicates hypoxemia. To manage hypoxemia, the nurse should increase oxygenation by administering oxygen via nasal cannula as ordered. Instructing the client to breathe into a paper bag would cause depressed oxygenation when the client reinhaled carbon dioxide. Auscultating breath sounds or encouraging deep breathing and coughing wouldn't improve oxygenation.
A nurse caring for a client with deep vein thrombosis must be especially alert for complications such as pulmonary embolism. Which findings suggest pulmonary embolism?
Chest pain and dyspnea As an embolus occludes a pulmonary artery, it blocks the supply of oxygenated blood to the heart, causing chest pain. It also blocks blood flow to the lungs, causing dyspnea. The client with pulmonary embolism typically has a cough that produces blood-tinged sputum (rather than a nonproductive cough) and chest pain (rather than abdominal pain). Hypertension, absence of fever, bradypnea, and bradycardia aren't associated with pulmonary embolism.
A client has undergone a left hemicolectomy for bowel cancer. Which activities prevent the occurrence of postoperative pneumonia in this client?
Coughing, breathing deeply, frequent repositioning, and using an incentive spirometer Activities that help to prevent the occurrence of postoperative pneumonia are: coughing, breathing deeply, frequent repositioning, medicating the client for pain, and using an incentive spirometer. Limiting fluids and lying still will increase the risk of pneumonia.
A client diagnosed with acute respiratory distress syndrome (ARDS) is restless and has a low oxygen saturation level. If the client's condition does not improve and the oxygen saturation level continues to decrease, what procedure will the nurse expect to assist with in order to help the client breathe more easily?
Intubate the client and control breathing with mechanical ventilation A client with ARDS may need mechanical ventilation to assist with breathing while the underlying cause of the pulmonary edema is corrected. The other options are not appropriate.
A gerontologic nurse is teaching a group of medical nurses about the high incidence and mortality of pneumonia in older adults. What is a contributing factor to this that the nurse should describe?
Older adults often lack the classic signs and symptoms of pneumonia. The diagnosis of pneumonia may be missed because the classic symptoms of cough, chest pain, sputum production, and fever may be absent or masked in older adult clients. Mortality from pneumonia in older adults is not a result of limited antibiotic options or lower lung compliance. The pneumococcal vaccine is appropriate for older adults.
A client who has just had a triple-lumen catheter placed in his right subclavian vein complains of chest pain and shortness of breath. His blood pressure is decreased from baseline and, on auscultation of his chest, the nurse notes unequal breath sounds. A chest X-ray is immediately ordered by the physician. What diagnosis should the nurse suspect?
Pneumothorax Pneumothorax (air in the pleural space) is a potential complication of all central venous access devices. Signs and symptoms include chest pain, dyspnea, shoulder or neck pain, irritability, palpitations, light-headedness, hypotension, cyanosis, and unequal breath sounds. A chest X-ray reveals the collapse of the affected lung that results from pneumothorax. Triple-lumen catheter insertion through the subclavian vein isn't associated with pulmonary embolism, MI, or heart failure.
During a community health fair, a nurse is teaching a group of seniors about promoting health and preventing infection. Which intervention would best promote infection prevention for senior citizens who are at risk of pneumococcal and influenza infections?
Receive vaccinations 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.
A client who has recently started working in a coal mine is concerned the effects on long-term health. How does the nurse advise the client to prevent occupational lung disease? Select all that apply.
Wear appropriate protective equipment when around airborne irritants and dusts. Do not smoke, or quit smoking if currently smoking. The nurse may instruct clients that the following precautions may help prevent occupational lung disease: not smoking, wearing appropriate protective equipment when around airborne irritants and dusts, scheduling lung function evaluation with spirometry as recommended, becoming educated about lung diseases, and paying attention to risk evaluation of the workplace to identify risks for lung disease.
A client admitted with multiple traumatic injuries receives massive fluid resuscitation. Later, the physician suspects that the client has aspirated stomach contents. The nurse knows that this client is at highest risk for:
acute respiratory distress syndrome (ARDS). A client who receives massive fluid resuscitation or blood transfusions or who aspirates stomach contents is at highest risk for ARDS, which is associated with catastrophic events, such as multiple trauma, bacteremia, pneumonia, near drowning, and smoke inhalation. COPD refers to a group of chronic diseases, including bronchial asthma, characterized by recurring airflow obstruction in the lungs. Although renal failure may occur in a client with multiple trauma (depending on the organs involved), this client's history points to an assault on the respiratory system secondary to aspiration of stomach contents and massive fluid resuscitation.
A client who underwent thoracic surgery to remove a lung tumor had a chest tube placed anteriorly. The surgical team places this catheter to:
remove air from the pleural space. After thoracic surgery, draining secretions, air, and blood from the thoracic cavity is necessary to allow the lungs to expand. A catheter placed in the pleural space provides a drainage route through a closed or underwater-seal drainage system to remove air. Sometimes two chest catheters are placed following thoracic surgery: one anteriorly and one posteriorly. The anterior catheter removes air; the posterior catheter removes fluid.
A nurse is giving a speech addressing "Communicable Diseases of Winter" to a large group of volunteer women, most of whom are older than 60 years. What preventive measures should the nurse recommend to these women, who are at the risk of pneumococcal and influenza infections? Select all that apply.
vaccinations hand antisepsis 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.
