Answer key

Pneumothorax case study: answers and rationales

Try the questions first. Open one to read its answer and rationale.

Question 1: Recognize cuesClick to highlight the findings below that require immediate follow-up.

Sudden sharp chest pain that is worse with a deep breath is pleuritic pain, and chest pain and shortness of breath are common symptoms of pneumothorax. The client also speaks in short sentences, the left chest moves less than the right, there are no breath sounds over the left lung and the percussion note is hyperresonant. The one-sided loss of breath sounds with a hyperresonant note is the finding that points to a pneumothorax, and together these findings show that air in the pleural space is affecting breathing. Smoking and a tall build are linked to pneumothorax but are not findings that need action now. The skin is warm and dry with pink lips, and the neck veins are flat, so neither needs immediate action. Takeaway: sudden pleuritic chest pain and shortness of breath, with absent breath sounds on one side and a hyperresonant note, point to pneumothorax and need immediate follow-up.

Question 2: Analyze cuesFor each finding below, click to specify if the finding is consistent with the disease process of pneumothorax or pneumonia. Each finding may support more than 1 disease process.

The 0910 findings are compared with two conditions that can cause chest pain and shortness of breath. Sharp chest pain that is worse with a deep breath and a pulse oximetry reading of 91% on room air occur with a pneumothorax and with pneumonia, and smoking raises the risk of both, so these findings do not separate them. The finding that separates them is the percussion note over the quiet left lung. Tapping over air in the pleural space gives more echo than usual, a hyperresonant note, while the dense lung of pneumonia gives a dull note and crackles. Men who are taller than average are more likely to have a spontaneous pneumothorax, and this client is a 22-year-old man who is 188 cm tall. Takeaway: chest pain, a low oxygen reading and smoking fit both pneumothorax and pneumonia; absent breath sounds with a hyperresonant note point to a pneumothorax.

Question 3: Prioritize hypothesesComplete the following sentence by choosing from the list of options.

The deciding cues are the absent breath sounds over the left lung with a hyperresonant note, together with a pulse of 112/min, respirations of 26/min and a pulse oximetry reading of 91% on room air. These show a pneumothorax that is already affecting breathing. Left untreated, a pneumothorax can progress to a tension pneumothorax: a very large pneumothorax that interferes with blood flow through the chest and can lead to failure of the heart and lungs. A pulmonary embolism can also cause pleuritic pain, fast breathing and a low oxygen reading, but one-sided absent breath sounds with a hyperresonant note point to air in the pleural space and not to a clot. Hypovolemic shock follows blood loss, and the notes record no bleeding. Takeaway: in a pneumothorax, the complication to watch for is a tension pneumothorax; worsening distress, a falling pulse oximetry reading and a rising pulse can come before the blood pressure falls.

Question 4: Generate solutionsFor each potential nursing action, click to specify whether the action is indicated or not indicated for the care of the client.

The repeat film after needle aspiration shows the air space unchanged, and a chest tube is ordered. The order is for water-seal drainage and for oxygen titrated to a printed range, so the nurse gives oxygen as ordered and does not connect the unit to wall suction, which is not ordered. Care for a client with a chest tube keeps the client sitting upright, which supports deep breathing. Sterile petroleum gauze and tape stay at the bedside for an emergency such as a tube that comes out of the chest. Coughing and deep breathing are encouraged, so the client is not taught to avoid coughing. Takeaway: with a chest tube, give care as ordered, keep the client upright, encourage coughing and deep breathing and keep dressing supplies at the bedside.

Question 5: Take actionSelect the 3 actions the nurse should take.

The deciding cue is the drainage unit that was knocked over: it lies on its side and the water level in the water-seal chamber is below the 2 cm mark. The tube is still attached, and the client is breathing without distress. For a unit that has been knocked over, the nurse sets it upright, checks the water-seal level and refills it. The nurse also assesses the client's breathing and pulse oximetry reading, because the unit is part of the treatment for a pneumothorax. A tube is not clamped routinely, because of the risk of a tension pneumothorax. The unit is kept below the level of the chest, not lifted to it. Removing the tube is not a nursing response to a tipped unit, and waiting for the next scheduled check leaves the problem unfixed. Takeaway: when the drainage unit is knocked over, set it upright, check the water-seal level and refill it, and assess the client.

Question 6: Evaluate outcomesFor each assessment finding, click to specify if the finding indicates that the client's condition has improved, not changed, or worsened.

Each Day 2 finding is compared with the earlier chart. Improved: the respiratory rate is 16/min, down from 26/min on admission and within the adult range of 12–20/min; the pulse is 82/min, down from 112/min and within the adult range of 60–100/min; and the pulse oximetry reading is 98% on room air, up from 91% and inside the ordered range of 94–98%. Not changed: the temperature is normal at each check, and the water level still rises and falls with breathing, which shows that the tube is patent. Worsened: the drainage was pale yellow and clear and is now cloudy. Cloudy drainage can be a sign of infection, so the nurse notifies the primary health care provider (PHCP). Takeaway: a client can improve in oxygenation and breathing while a new finding, such as cloudy chest tube drainage, still needs prompt follow-up.

FAQ

NCLEX pneumothorax and chest tube questions: FAQ

What are three signs of a collapsed lung?
Chest pain, shortness of breath and a fast heart rate are three common ones. The pain of a pneumothorax is typically sharp or stabbing and worse when the client breathes in, and a small collapse may cause no symptoms at all. On assessment, breath sounds may be decreased and the chest may move unevenly, tapping over the affected side gives more echo than usual (a hyperresonant note), and the client may breathe fast, look cyanotic or have a low oxygen reading. A chest x-ray shows the air in the pleural space.
What are the different types of pneumothorax?
NHLBI describes three. A spontaneous pneumothorax happens suddenly, often with no known cause and in people with no sign of lung disease, although a lung disease such as COPD can also cause one; smoking raises the risk, and men, especially tall men, have it more often than women. A traumatic pneumothorax follows a chest injury, and procedures such as a lung biopsy, mechanical ventilation, thoracentesis or a central line insertion can also let air into the pleural space. The third, a tension pneumothorax, is a very large pneumothorax and a medical emergency.
What is a tension pneumothorax?
A pneumothorax so large that it interferes with blood flow through the chest, so the blood pressure can drop and the heart and lungs can fail. An untreated pneumothorax can progress to it. In an awake client the usual early signs are worsening respiratory distress, a fast heart rate and a falling oxygen level; low blood pressure comes late, and a trachea pushed to one side or distended neck veins are less common, so the nurse never waits for them. The nurse gives oxygen and notifies the provider at once, checks that a chest tube system, if there is one, has no leak, kink or clamp, and the chest is decompressed without delay.
What are the nursing interventions for a chest tube?
Keep the drainage unit upright and below the level of the chest, set on a surface that cannot move or hung on the bed, with the water seal filled to the 2 cm mark. Watch for tidaling, the water level rising and falling with breathing, which shows that the tube is patent. Never strip the tubing, and do not clamp it routinely, because clamping risks a tension pneumothorax. Mark the drainage level with the time, record its amount and appearance, and notify the provider about cloudy drainage, drainage that averages more than 200 mL an hour for 4 hours, or drainage that stops in the first 24 hours. Help the client sit upright, cough, breathe deeply and use an incentive spirometer, give pain medicine as prescribed, and assess breathing and pain every 2 to 4 hours or as agency policy directs. Keep rubber-tipped clamps, sterile gauze, petroleum gauze, tape and a small container of sterile water or saline at the bedside.
How can you tell if a chest tube has an air leak?
Look at the water-seal chamber: continuous or intermittent bubbling there can mean an air leak, while a water level that only rises and falls with breathing is expected. First look for an outside cause, such as a loose connection, and check that the tube has not come out. To find the source, the nurse clamps the tubing briefly, starting at the dressing and moving toward the drainage unit. If the bubbling stops with the clamp near the chest, the leak is at the insertion site or inside the chest, so the nurse reinforces the dressing and notifies the provider; if it goes on even with the clamp next to the unit, the drainage system leaks and is replaced. Notify the provider immediately if the tube is dislodged or the leak cannot be fixed, because an air leak can mean the pneumothorax is getting worse.
