Recognising Acute Abdominal Pain for Student Nurses
Learn how to assess new or worsening abdominal pain, recognise associated warning signs and identify patterns that may indicate significant patient deterioration.
Start with the patient's description
New abdominal pain can range from mild discomfort to severe acute pain. Understanding what the patient is experiencing helps establish whether their condition is changing and what requires further assessment.
When did it start?
Establish when the pain began and whether the onset was sudden, progressive or associated with a particular event.
Where is the pain?
Ask the patient to describe where the pain is and whether it moves or radiates elsewhere.
How bad is it?
Use an appropriate pain assessment method and compare the pain with earlier reports where possible.
Listen to the patient's concern
A patient saying that their pain is suddenly different, much worse or unlike anything they have experienced previously should prompt further assessment.
Use a structured approach
Site
Ask where the pain is located and whether it is localised or more widespread.
Onset
Establish when the pain began and whether it appeared suddenly or developed gradually.
Character
Ask how the patient would describe the pain, such as sharp, cramping, burning, aching or pressure-like.
Radiation
Ask whether the discomfort stays in one place or travels to another area.
Associated symptoms
Ask about nausea, vomiting, bowel changes, urinary symptoms, bleeding, dizziness or breathlessness.
Timing
Establish whether the pain is constant, intermittent, worsening or changing over time.
Exacerbating or relieving factors
Ask whether movement, eating, position or other factors make the pain better or worse.
Severity
Use an appropriate pain scale and interpret the score alongside the patient's behaviour and condition.
Look beyond the pain score
| Finding | What you may notice | Why it increases concern |
|---|---|---|
| Severe or rapidly worsening pain | The patient describes a major change or escalating pain. | A sudden change in symptoms requires further clinical assessment. |
| Abdominal guarding or rigidity | The patient appears tense, protective or reluctant to move. | These observations may accompany significant abdominal pathology. |
| Tachycardia | The pulse is significantly faster than previously. | This may accompany pain, fluid loss, bleeding or wider physiological stress. |
| Falling blood pressure | Blood pressure falls from the patient's baseline. | This may indicate developing circulatory compromise. |
| Pallor or clammy skin | The patient becomes pale, cool or sweaty. | This can form part of a wider pattern of deterioration. |
| Altered consciousness | New confusion, agitation, drowsiness or collapse. | Neurological change alongside acute pain requires prompt attention. |
Assess the whole patient
Airway
Confirm that the airway is patent and identify any immediate airway concern.
Breathing
Assess respiratory rate, oxygen saturation, work of breathing and any associated breathlessness.
Circulation
Review pulse, blood pressure, skin, perfusion and any evidence of bleeding or fluid loss.
Disability
Assess consciousness and identify dizziness, confusion, drowsiness or collapse.
Exposure
Observe the abdomen and other relevant findings within your role, maintaining privacy and dignity.
Escalate
Communicate significant pain or associated deterioration promptly according to local escalation procedures.
Ask what else has changed
Abdominal pain often occurs alongside other symptoms. These can help describe the clinical picture and identify patients who require prompt review.
Nausea and vomiting
Ask about vomiting, reduced intake, diarrhoea, constipation and any change in bowel habit.
Urinary symptoms
Ask about pain when passing urine, frequency, reduced urine output or other changes where relevant.
Wider illness
Fever, weakness, dizziness, pallor, sweating or altered consciousness may indicate wider deterioration.
When should abdominal pain concern you?
- Sudden severe abdominal pain.
- Rapidly worsening pain or a significant change from earlier symptoms.
- Pain accompanied by tachycardia or falling blood pressure.
- New pallor, clamminess, weakness or collapse.
- Persistent vomiting with signs of dehydration or deterioration.
- New confusion, drowsiness or reduced responsiveness.
- Visible or reported bleeding.
- A markedly distended abdomen or significant guarding.
- Abdominal pain combined with breathlessness or chest symptoms.
- A patient who simply appears significantly more unwell than before.
Do not wait for a diagnosis before escalating
Student nurses are not expected to determine the cause of acute abdominal pain independently. Your role is to recognise significant change, assess the patient and communicate concerns clearly.
The patient's condition may change over time
Mild discomfort
Patient reports mild abdominal discomfort and observations are close to baseline.
Pain increasing
The patient reports worsening pain and begins to feel nauseated and weak.
Deterioration
Pain is severe, pulse has increased, blood pressure has fallen and the patient appears pale and clammy.
The trend matters
Progressive pain combined with changing observations can reveal a developing clinical problem that may not have been obvious during an earlier assessment.
Putting the findings together
Example
A patient who reported mild abdominal discomfort earlier now tells you the pain has suddenly become much worse.
They look pale and uncomfortable and are reluctant to move. Their pulse has increased from 82 to 116 beats per minute and their blood pressure is lower than their previous observations.
They also feel nauseated and light-headed.
The concern is the combined pattern of worsening abdominal pain, tachycardia, falling blood pressure and visible clinical deterioration.
As a student nurse, recognise the change, begin an appropriate ABCDE assessment within your competence and promptly communicate your findings to the registered nurse or relevant clinical team.
Assessment errors to avoid
- Focusing only on the pain score. Assess the whole patient.
- Assuming abdominal pain is minor. Look for changing observations and associated symptoms.
- Failing to compare with earlier symptoms. Change over time is important.
- Ignoring pulse and blood pressure. Abdominal symptoms can occur alongside circulatory deterioration.
- Missing nausea, vomiting or bleeding. Ask about associated symptoms.
- Trying to diagnose the cause. Focus first on recognition, assessment and escalation.
- Delaying escalation while repeatedly reassessing. Seek help promptly when the clinical picture is concerning.
Describe both the pain and the deterioration
Example escalation
“I'm concerned about Mr Williams. His abdominal pain has suddenly become severe. His pulse has increased from 82 to 116 and his blood pressure has fallen compared with earlier. He looks pale and clammy and says he feels light-headed and nauseated.”
This communicates the change in symptoms, objective observations and reason for concern.
Recognise → assess → communicate → escalate
Notice new or worsening pain
Establish what has changed and identify associated symptoms or deterioration.
Use ABCDE
Assess the pain alongside respiratory, circulatory and neurological observations.
Describe the pattern
Report the onset, severity, associated symptoms, observations and changes from baseline.
