Appendicitis is the inflammation of the vermiform appendix. It is classified as a medical emergency and often requires excision of the inflamed appendix. If left untreated, appendicitis can lead to peritonitis and shock.
Pathophysiology of Appendicitis
If an obstruction by a fecalith or by a parasite occur, inflammation of the vermiform appendix occurs. It can then increase the intraluminal pressure and cause rupture of the appendix.
Signs and Symptoms of Appendicitis
- Anorexia
- Epigastric pain (Periumbilical)
- Right lower quadrant pain (McBurney’s area)
- Nausea and vomiting
- Diarrhea
- Body malaise
- Low grade fever
- Sudden relief of pain (Signifies rupture of the appendix)
Findings on Physical Examination for Appendicitis
- Direct tenderness
- Rebound tenderness
- When hyperextension of the right thigh is performed, there is positive right lower quadrant pain (Psoas’ Sign)
- Internal examination reveal that there is positive cervical tenderness
Diagnostic Exams for Appendicitis
- Ultrasound – confirmatory diagnostic exam for appendicitis
- Chest X-Ray – to rule out right lobar pneumonia
- CBC – look for increased white blood cell count
Management for Appendicitis
- Administer IV Antibiotics.
- Appendectomy.
- For ruptured appendix, an emergency explore laparotomy is performed. Peritoneal lavage is done with normal saline solution.
Nursing Diagnosis for Appendicitis
Acute Pain
Nursing Interventions:- Assess the severity and location of pain. If client presents with board-like rigidity and severe pain, suspect for peritonitis.
- Administer analgesics after a diagnosis is made.
- Assess the effectiveness of the analgesic given.
- Position client in a supine position with thighs slightly flexed.
Risk for Infection
Nursing Interventions:- Administer antibiotics as ordered.
- Practice aseptic technique.
- Position client in right lateral semi-Fowler’s position post-operation for ruptured appendix to localize infectious process.
