Rib Fractures nursing care: what to assess and what to do first
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
Rib fractures are managed by treating the consequence, not the bone. The break itself usually heals without intervention, but pain-driven shallow breathing leads to atelectasis and pneumonia, so analgesia and incentive spirometer use are the priority nursing actions, ahead of imaging or immobilisation.
Recognising it at the bedside
Suspect a rib fracture in any patient with localised chest wall pain following trauma, a fall, or even a severe coughing fit in someone with osteoporosis or lung disease. Pain is typically sharp, well-localised, and worsens with deep breathing, coughing, or movement, which is the clinical clue that distinguishes it from cardiac or visceral pain.
Palpate gently over the area of reported pain for point tenderness and crepitus, and observe the patient's breathing pattern: shallow, rapid breaths and a reluctance to take a deep breath or cough are common compensations. Auscultate breath sounds, since diminished or absent sounds on the affected side may indicate a developing pneumothorax or haemothorax, complications that turn a simple rib fracture into an emergency.
Why the classic presentation misleads
Rib fractures are easy to underestimate because the bone injury is rarely what harms the patient. The fracture itself typically heals in four to six weeks with no specific treatment beyond pain control, and many rib fractures are not even splinted or immobilised, since chest wall immobilisation would restrict breathing rather than protect the injury.
The real danger develops indirectly. Pain causes the patient to breathe shallowly and avoid coughing, which allows secretions to pool and alveoli to collapse, setting up atelectasis and, within days, pneumonia. This is why a nurse should never treat a rib fracture as a low-acuity injury simply because there is no fracture displacement or associated organ injury visible on imaging; the trajectory that matters is respiratory, not orthopaedic. This risk rises sharply with age, with three or more fractured ribs, and with pre-existing lung disease.
Priority nursing actions
Analgesia comes first and should be proactive rather than reactive; adequate pain control is what allows the patient to breathe deeply and cough effectively, which directly prevents the pneumonia that is the actual threat. Multimodal approaches combining scheduled non-opioid analgesics with opioids as needed, or regional techniques for more severe or multiple fractures, are commonly used to control pain without oversedating the patient and further suppressing respiratory effort.
Introduce the incentive spirometer immediately and coach its use every one to two hours while awake, since this directly reverses the shallow-breathing pattern that leads to atelectasis. Encourage coughing and deep breathing with splinting support, using a pillow held against the chest to reduce pain during the effort. Position the patient upright or semi-Fowler's to optimise lung expansion, and mobilise as early as tolerated, since prolonged bed rest compounds the risk of pooled secretions.
Labs and diagnostics to expect
A chest X-ray is standard to confirm the fracture, check for displacement, and screen for a pneumothorax or haemothorax, though rib fractures can be missed on plain film, particularly non-displaced ones; CT is more sensitive when suspicion is high or the mechanism was severe. Serial chest X-rays or clinical reassessment may be repeated if a delayed pneumothorax or haemothorax is suspected, since these can develop hours after the initial injury.
Pulse oximetry should be monitored continuously or at frequent intervals, and arterial blood gases may be drawn if respiratory status declines, since hypoxaemia can develop gradually as atelectasis progresses. In older adults or those with multiple rib fractures, a baseline and trending white blood cell count and chest imaging help catch early pneumonia before it becomes clinically obvious.
Complications and their early signs
Pneumonia is the complication to watch for most closely, and early signs include a new or worsening cough, increasing sputum production or a change in colour, low-grade fever, and rising respiratory rate, often preceding any dramatic change in oxygen saturation. A delayed pneumothorax can present as sudden worsening dyspnoea, asymmetric chest wall movement, and diminished breath sounds on the affected side, sometimes days after the initial injury.
Flail chest is a possible progression if enough ribs are involved with fractures in multiple places, presenting as visible paradoxical chest wall movement. Older adults with three or more rib fractures carry a notably higher risk of pneumonia and respiratory failure, and this population deserves closer monitoring and a lower threshold for escalating pain management and pulmonary hygiene.
Teaching that changes outcomes
Teach the patient, before discharge, that the goal is to keep breathing deeply and coughing despite the pain, not to protect the fracture by breathing shallowly. Frame pain medication as a tool for achieving that deep breathing rather than something to avoid or ration, since patients who under-medicate out of fear of opioids often end up with worse respiratory outcomes.
Reinforce use of the incentive spirometer at home if one is provided, along with splinted coughing technique using a pillow or folded towel against the chest. Advise the patient and family to watch for and report fever, increasing shortness of breath, or a productive cough with discoloured sputum, since these are the early warning signs of the pneumonia this whole care plan is designed to prevent. Set realistic expectations that pain may persist for several weeks even as healing progresses.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our respiratory practice questions are the closest set to what this page covers.
Common questions
Do rib fractures need to be immobilised or splinted with a binder?
No. Chest binders and rigid immobilisation are generally avoided because they restrict chest wall movement and deep breathing, which increases the risk of atelectasis and pneumonia. Pain control that allows normal breathing is the preferred approach instead.
How many rib fractures are considered high risk?
Three or more rib fractures, particularly in older adults, are associated with a significantly higher risk of pneumonia and respiratory complications and usually warrant closer monitoring, sometimes including admission for pulmonary hygiene and pain management. Even a single fracture in an older or frail patient deserves vigilant respiratory monitoring.
Why is the incentive spirometer used for rib fractures if the ribs aren't the lungs?
The incentive spirometer targets the actual complication risk, which is atelectasis and pneumonia from pain-limited shallow breathing, not the fracture itself. Regular use encourages deep, sustained breaths that keep alveoli open and secretions mobilised while the rib heals on its own.
How long does pain from a rib fracture typically last?
Pain often improves over two to four weeks, though it can persist for six weeks or longer, particularly with deep breathing, coughing, or certain movements. Persistent or worsening pain beyond this timeframe, especially with new respiratory symptoms, should prompt reassessment for a complication such as delayed pneumothorax or pneumonia.
