NCLEX Review Guide: Tonsillitis & Adenoiditis in Pediatrics

Tonsillitis Overview

• Tonsillitis refers to inflammation of the palatine tonsils, which are lymphoid tissue masses located on either side of the oropharynx. The condition is common in children aged 5-15 years and is typically caused by viral pathogens (70%) or bacterial infections (primarily Group A beta-hemolytic streptococci).
• Tonsils serve as the body's first line of defense against ingested or inhaled pathogens, but when overwhelmed by infectious agents, they become inflamed and enlarged, potentially obstructing the airway.

Adenoiditis Overview

• Adenoiditis is inflammation of the adenoid tissue (nasopharyngeal tonsils) located at the back of the nasal cavity. This condition frequently occurs in children aged 3-7 years and often coexists with tonsillitis.
• Enlarged adenoids can obstruct the eustachian tubes, leading to recurrent otitis media, and may block nasal airflow, resulting in obligate mouth breathing and potential sleep disturbances.

Clinical Manifestations

• Tonsillitis Symptoms: Sore throat, painful swallowing (odynophagia), fever (often >101°F/38.3°C), malaise, headache, enlarged and erythematous tonsils with exudates, and tender anterior cervical lymphadenopathy.
• Adenoiditis Symptoms: Persistent nasal congestion, mouth breathing, hyponasal speech ("talking through the nose"), snoring, sleep apnea, recurrent otitis media, and halitosis.

Laboratory & Diagnostic Tests

• Rapid antigen detection test (RADT) for Group A streptococcus has high specificity (95%) but moderate sensitivity (70-90%), so negative results may require throat culture confirmation.
• Complete blood count may show leukocytosis with bacterial infection, and throat culture remains the gold standard for diagnosing streptococcal pharyngitis with 90-95% sensitivity.
• For adenoiditis, lateral neck radiographs or nasopharyngoscopy may be used to visualize adenoid hypertrophy and assess the degree of nasopharyngeal obstruction.

Differential Diagnosis

• Important differential diagnoses include viral pharyngitis, infectious mononucleosis (characterized by prolonged symptoms, fatigue, and posterior cervical lymphadenopathy), peritonsillar abscess, retropharyngeal abscess, and diphtheria (rare but serious).
• For adenoiditis, consider allergic rhinitis, chronic sinusitis, nasal foreign body, and congenital nasal obstruction in the differential diagnosis.

Pharmacological Management

• Antibiotics for Bacterial Tonsillitis: Penicillin V remains the first-line treatment for Group A streptococcal tonsillitis (10-day course). For penicillin-allergic patients, alternatives include macrolides (azithromycin) or first-generation cephalosporins if no anaphylactic history.
• Symptomatic Treatment: Acetaminophen or ibuprofen for pain and fever management, throat lozenges (for children old enough to safely use them), and adequate hydration are essential supportive measures for both viral and bacterial cases.

Administering Intramuscular Penicillin G Benzathine

1. Verify patient identity and medication order, checking for penicillin allergies.
2. Explain procedure to child and parents, emphasizing single-dose advantage.
3. Prepare injection site (vastus lateralis for younger children, ventrogluteal for older).
4. Administer using appropriate needle length based on child's size.
5. Monitor for at least 30 minutes post-injection for allergic reactions.

Surgical Management

• Tonsillectomy is considered when a child experiences: ≥7 episodes of tonsillitis in one year, ≥5 episodes per year for two consecutive years, ≥3 episodes per year for three consecutive years, peritonsillar abscess, or obstructive sleep apnea.
• Adenoidectomy is typically performed for persistent nasal obstruction, chronic adenoiditis, recurrent otitis media unresponsive to antibiotics, or as part of management for obstructive sleep apnea. It is often performed concurrently with tonsillectomy (adenotonsillectomy).

Preoperative Nursing Care

• Assess for bleeding disorders through history and laboratory tests as indicated; bleeding time, PT/PTT, and platelet count may be ordered preoperatively.
• Provide age-appropriate education about the procedure, postoperative expectations, and pain management strategies to both the child and parents.

Postoperative Nursing Care

• Monitor vital signs, respiratory status, and bleeding frequently. Position the child in lateral or prone position with head slightly elevated to prevent aspiration of blood and facilitate drainage.
• Encourage adequate fluid intake with cool, non-acidic, non-carbonated fluids. Avoid red or brown liquids that could mask blood in emesis. Progress diet as tolerated from clear liquids to soft foods.

Patient & Family Education

• Instruct on proper medication administration, emphasizing the importance of pain control to maintain adequate hydration. Teach parents to alternate acetaminophen and ibuprofen (if approved by surgeon) for optimal pain management.
• Educate about activity restrictions (usually 2 weeks), avoiding hot, spicy, rough, or acidic foods, and the importance of follow-up appointments.

Complications of Untreated Infections

• Tonsillitis Complications: Untreated streptococcal tonsillitis can lead to peritonsillar abscess (quinsy), rheumatic fever, post-streptococcal glomerulonephritis, and scarlet fever. Chronic tonsillitis may cause halitosis and persistent sore throat.
• Adenoiditis Complications: Chronic adenoiditis can lead to chronic sinusitis, eustachian tube dysfunction with resultant recurrent otitis media, conductive hearing loss, and obstructive sleep apnea with potential growth and developmental impacts.

Surgical Complications

• Tonsillectomy Complications: Hemorrhage (primary within 24 hours or secondary at 5-10 days), dehydration, pain, postoperative nausea and vomiting, respiratory complications, and rare complications like velopharyngeal insufficiency or nasopharyngeal stenosis.
• Adenoidectomy Complications: Bleeding, velopharyngeal insufficiency (characterized by hypernasal speech and nasal regurgitation of fluids), and eustachian tube scarring.

Preventive Measures

• Promote good hand hygiene and avoid sharing utensils or drinks to reduce transmission of infectious agents that cause tonsillitis and adenoiditis.
• Ensure complete antibiotic courses for bacterial infections to prevent recurrence and complications. Prompt treatment of streptococcal pharyngitis can prevent rheumatic fever and other sequelae.

Tonsillitis vs. Pharyngitis

Adenoids vs. Tonsils

Viral vs. Bacterial Tonsillitis Treatment

• A common misconception is that all cases of tonsillitis require antibiotic treatment. In reality, most cases (70%) are viral in origin and antibiotics are ineffective and potentially harmful due to side effects and antimicrobial resistance.
• Only confirmed or highly suspected Group A streptococcal tonsillitis requires antibiotic therapy, primarily to prevent rheumatic fever and other complications rather than to shorten illness duration (though antibiotics do typically reduce symptoms by 24-48 hours).

Priority Nursing Interventions

• For NCLEX questions about tonsillitis and adenoiditis, remember that airway management is always the priority. Questions may test your ability to recognize signs of respiratory distress or airway obstruction from severely enlarged tonsils or adenoids.
• When answering questions about post-tonsillectomy care, prioritize assessments and interventions related to hemorrhage detection and management, as this is the most life-threatening complication.

Common NCLEX Question Themes

• Expect questions on distinguishing viral from bacterial tonsillitis, appropriate antibiotic therapy for Group A streptococcal infections, and recognition of complications like peritonsillar abscess or rheumatic fever.
• Post-operative care questions often focus on hemorrhage prevention and detection, pain management, hydration maintenance, and appropriate discharge teaching.

Common Pitfalls to Avoid

• Don't assume all sore throats with fever require antibiotics; viral causes are more common and antibiotics are inappropriate without evidence of bacterial infection.
• Avoid confusing expected post-tonsillectomy findings (white or yellow fibrinous exudate at surgical site, mild odor, referred ear pain) with complications requiring intervention.

Pathophysiology & Assessment

• Tonsillitis is inflammation of the palatine tonsils, most common in children 5-15 years, with 70% of cases being viral in origin.
• Adenoiditis affects the nasopharyngeal tonsils, peaks at ages 3-7 years, and often causes nasal obstruction, mouth breathing, and eustachian tube dysfunction.
• Key assessment findings for tonsillitis include sore throat, odynophagia, fever, and enlarged, erythematous tonsils with possible exudates.

Diagnostic & Therapeutic Management

• Rapid strep testing and throat culture help distinguish bacterial from viral tonsillitis, with bacterial cases requiring antibiotic treatment (typically penicillin V for 10 days).
• Surgical management (tonsillectomy/adenoidectomy) is indicated for recurrent infections, airway obstruction, or complications like peritonsillar abscess.
• Post-operative care focuses on hemorrhage prevention and detection, pain management, and maintaining adequate hydration.

Nursing Considerations

• Nursing priorities include airway assessment, pain management, hydration maintenance, and vigilant monitoring for post-operative complications, especially hemorrhage.
• Patient and family education should emphasize medication administration, diet progression, activity restrictions, and signs requiring immediate medical attention.
• Prevention strategies include good hand hygiene, completing prescribed antibiotic courses, and avoiding contact with infected individuals.
