Two nursing problems sit under pneumonia and they need different interventions. This guide separates impaired gas exchange from ineffective airway clearance and shows how to argue which one is the priority.
Two problems, not one
Pneumonia looks like a single diagnosis and produces two separate nursing problems. A nursing care plan of pneumonia that treats them as one, or lists both without deciding between them, has skipped the step the assignment is testing.
Impaired gas exchange is a problem of the alveolar membrane. Inflammatory exudate fills the alveolar spaces, so blood passes lung tissue that is perfused but not ventilated and returns to the circulation without having picked up oxygen. The patient is hypoxaemic.
Ineffective airway clearance is a problem of the airways above that. Secretions are produced faster than they are cleared, or the patient cannot generate an effective cough, so the airways obstruct. The patient may or may not be hypoxaemic yet.
They frequently coexist, and they are not the same thing. Suctioning a patient whose problem is alveolar consolidation will not correct the oxygenation. Increasing the inspired oxygen in a patient whose problem is a plug of retained secretion treats a number rather than a cause. The interventions diverge because the mechanisms do, which is why the plan has to say which one the data supports.
The data that establishes impaired gas exchange
This diagnosis is argued from oxygenation figures and the signs of the body compensating for a shortfall.
Oxygen saturation below the patient's normal, or a rising oxygen requirement to hold the same saturation. Respiratory rate raised, and raised consistently rather than in one estimated set. Use of accessory muscles, nasal flaring, an inability to complete a sentence. Restlessness and confusion, which are commonly missed as respiratory signs and attributed to the environment. Where an arterial blood gas has been taken, a low arterial oxygen tension confirms it, and a rising carbon dioxide tension indicates a patient who is tiring rather than improving.
Auscultation supports rather than establishes it. Reduced air entry and bronchial breathing over the affected area point to consolidation, and the systematic examination across body systems is what generates these findings in an order that can be defended.
A worked statement: Impaired gas exchange related to alveolar inflammatory exudate and ventilation-perfusion mismatch, as evidenced by oxygen saturation of 89 per cent on air rising to 94 per cent on two litres, respiratory rate 28, use of accessory muscles, and bronchial breathing at the right base.
The data that establishes ineffective airway clearance
This diagnosis is argued from secretions and from the cough, and its evidence looks quite different.
A productive cough, or a cough the patient cannot make effective. Sputum described by volume, colour and viscosity, because thick sputum is the problem and thin sputum is not. Coarse crackles or wheeze that changes after coughing, which is the finding that most directly distinguishes retained secretion from consolidation. A patient who is too weak, too painful or too drowsy to clear their own airway, which is common after surgery and in older patients.
A worked statement: Ineffective airway clearance related to increased sputum production and an ineffective cough secondary to fatigue and pleuritic chest pain, as evidenced by coarse crackles at both bases clearing partially after coughing, thick green sputum, and the patient's report that he cannot cough deeply because "it catches".
The aetiology in that statement is doing real work. Fatigue and pain are things a nurse can act on directly, through timing analgesia before physiotherapy and pacing activity. Writing "related to pneumonia" instead would have named the medical diagnosis and left the plan with nothing to intervene on, which is the same circularity that undermines any NANDA-I statement whose aetiology restates the problem.
Arguing which one is the priority
Both problems are usually present. The plan has to say which comes first, and the argument is what earns the marks rather than the answer.
The general rule follows airway, breathing and circulation, which would place airway clearance above gas exchange. In practice the sequence follows the data. If the patient is desaturating despite a clear airway and a weak but adequate cough, gas exchange is the priority and the plan says so. If the patient's saturation recovers after a productive cough and falls again as secretions accumulate, airway clearance is driving the picture and correcting it will correct the oxygenation.
State the reasoning in a sentence. "Ineffective airway clearance is prioritised because saturation rose from 89 to 94 per cent after an effective cough without any change in inspired oxygen, indicating that retained secretion rather than consolidation is the immediate limiting factor." That sentence is the difference between a plan that lists diagnoses and a plan that reasons.
Where the patient is systemically unwell rather than only breathless, the priority may sit outside the respiratory diagnoses altogether. Pneumonia is a common source of sepsis, and a patient with a rising respiratory rate, new confusion and falling urine output is being assessed against a different pathway. Our plan for the deteriorating septic patient covers that recognition step and the escalation that follows.
Interventions for gas exchange, with the mechanism stated
Position the patient upright, or side-lying with the unaffected lung dependent where only one side is involved. Rationale: blood flow follows gravity to the lower lung, so placing the healthier lung in the dependent position matches the best perfused tissue with the best ventilated tissue and improves oxygenation without any change in inspired oxygen. This is the intervention most often given a rationale of "to help breathing", which explains nothing.
Administer oxygen as prescribed and titrate to the target range rather than to the maximum. Rationale: the target range is set for the patient, and in some patients with chronic carbon dioxide retention an unnecessarily high inspired oxygen suppresses respiratory drive, so more is not uniformly better.
Monitor respiratory rate, work of breathing and saturation together, and count the rate rather than estimating it. Rationale: saturation is held up by compensation until compensation fails, so the respiratory rate deteriorates first and is the earlier warning of the two.
Pace activity and cluster care to allow uninterrupted rest. Rationale: oxygen demand rises with every exertion including washing and repositioning, so in a patient whose supply is already limited the way care is scheduled directly affects oxygenation.
Watch for restlessness and new confusion as respiratory signs. Rationale: the brain shows the effects of hypoxaemia before the patient reports breathlessness, and attributing new confusion to the ward environment delays recognition.
Interventions for secretion clearance
Maintain fluid intake within any prescribed limit. Rationale: hydration keeps secretions thin enough to be moved by ciliary action and coughing, and a dehydrated patient produces sputum that no amount of coughing technique will shift. The limit matters, because a patient with cardiac disease may have a fluid restriction that overrides this.
Teach deep breathing and an effective cough, and time it after analgesia. Rationale: an effective cough requires a deep inspiration and a forceful expiration, both of which a patient with pleuritic pain will avoid; treating the pain first is what makes the technique available. Splinting the chest or abdomen with a folded blanket reduces the pull on painful tissue during the effort.
Mobilise the patient as tolerated, including sitting out of bed. Rationale: upright posture increases lung volumes and movement redistributes ventilation, so mobilisation clears secretion more effectively than any breathing exercise performed lying flat.
Support prescribed chest physiotherapy and breathing devices, and reinforce the technique between sessions. Rationale: these work through repetition, and a technique performed correctly twice a day with the therapist and incorrectly in between does not achieve the intended effect.
Record sputum volume, colour and viscosity at each shift. Rationale: a change in the character of sputum is an early indicator of response or of a new organism, and it is only visible as a trend, which requires the description to be recorded consistently rather than as "productive cough".
The supporting diagnoses that are not filler
Plans often add secondary diagnoses to fill a proforma. In pneumonia three of them do genuine work and are worth including for a stated reason.
Hyperthermia. Fever raises metabolic rate and therefore oxygen demand, in a patient whose oxygen supply is the limiting factor. Managing it is not comfort care alone; it reduces the load on the same system the primary diagnosis is about.
Activity intolerance. The gap between oxygen supply and demand is the same imbalance the primary diagnosis names, expressed in what the patient can do. It is measured by what they achieve rather than by what they report, and it is the most legible marker of recovery to the patient themselves.
Imbalanced nutrition, less than body requirements. Laboured breathing carries a metabolic cost that is easy to underestimate, and eating while breathless is genuinely difficult. Small frequent portions and attention to timing around physiotherapy and rest do more than a large tray the patient cannot face.
Risk for infection also belongs where the patient carries invasive devices, and it is written with risk factors rather than an "as evidenced by" clause.
Evaluating: which numbers move, and how fast
Setting the evaluation interval correctly requires knowing which measurements respond quickly and which do not.
Oxygen saturation and respiratory rate respond within minutes to positioning and oxygen, and within an hour to an effective cough. Sputum character changes over a day or two. Temperature settles over days once effective treatment has begun. Exercise tolerance and the chest radiograph lag by considerably longer, and radiographic clearing continues well after the patient feels recovered, which is worth stating in a plan because it prevents an evaluation that reads the radiograph as treatment failure.
A worked evaluation at 48 hours: saturation 95 per cent on air, up from 89 per cent, so the oxygenation goal is met and oxygen is discontinued. The patient produces a moderate volume of thinner sputum with an effective independent cough, so the airway clearance goal is met. He walks to the bathroom with one rest, having been unable to leave the bed on admission, so the activity goal is partially met and the target is extended rather than repeated. Temperature 37.4 degrees Celsius, down from 39.1, so the hyperthermia goal is met.
Discharge teaching closes the plan: completing the prescribed course, continuing the breathing exercises, the expected timescale for full recovery, and the symptoms that should prompt contact. Teaching structured so the patient can repeat it back is the difference between information delivered and information retained. Where the plan is being submitted for marking, a nursing writer can review the reasoning first.
