Nursing Clinical Practice Guide
Clinical Scenario: You are the nurse receiving a 4-year-old, unimmunized child from the ER who is lethargic, has a weak cough, and audible stridor when agitated. A thick, gray membrane is visible on the tonsils. The diagnosis of diphtheria is suspected.
Nursing Intervention Strategy:1. Immediate Action (First 5 minutes): Place the child in a private negative pressure room if available. Don appropriate PPE: N95 respirator (or mask per facility protocol), gown, gloves, and eye protection. Place "Droplet and Contact Precautions" signs. Ensure emergency equipment (suction, oxygen, bag-valve-mask, tracheostomy tray) is at the bedside.2. Assessment & Monitoring: Perform a focused respiratory assessment every 15-30 minutes initially. Use the Pediatric Assessment Triangle (PAT): Appearance (lethargic?), Work of Breathing (retractions, nasal flaring, stridor?), Circulation to Skin (pallor?). Monitor oxygen saturation continuously. Auscultate lung sounds. Key Point! Minimize agitation and procedures (like throat exams) that could dislodge the membrane and cause obstruction.3. Collaborative Care: Notify the provider immediately. Prepare for and assist with administration of diphtheria antitoxin after allergy skin testing. Administer IV or IM antibiotics as ordered. Provide humidified oxygen as needed. Ensure the child is placed on cardiac monitoring due to risk of myocarditis.4. Supportive Care & Education: Provide quiet, calm environment. Offer cool, soft liquids if the child can swallow safely (assess gag reflex). Educate family on the critical nature of isolation—no visitors, they must wear PPE. Explain all procedures to reduce fear.
Patient Safety and Precautions:• Airway: Never leave the child unattended. Have two nurses present if suctioning is required. Know the location of the difficult airway cart.• Infection Control: PPE must be donned before room entry and doffed properly upon exit. Limit staff exposure. The child is considered contagious until two cultures from the throat (taken 24 hours apart after antibiotic completion) are negative.• Medication: Antitoxin is most effective if given within 48 hours of symptom onset. Be vigilant for signs of serum sickness (fever, rash, joint pain) 7-14 days after antitoxin administration.
Nursing Procedure & Medication Flow
Procedure: Managing a Patient on Droplet/Contact Precautions1. Place patient in private room (or cohort with same infection).2. Wear a surgical mask (or N95 per protocol) upon entry.3. Wear gown and gloves for all contact with patient or environment.4. Limit patient transport; if necessary, patient wears a mask.5. Use dedicated equipment; disinfect shared equipment.
Medication: Diphtheria Antitoxin Administration• Pre-administration: Obtain informed consent. Perform a skin test for horse serum sensitivity (intradermal injection of a diluted sample). Observe for wheal and flare reaction.• Administration: If skin test negative, administer the antitoxin IV slowly as per protocol, monitoring closely for anaphylaxis (have epinephrine ready).• Post-administration: Monitor for delayed hypersensitivity (serum sickness).
A Word from Your Senior Nurse
"In pediatrics, a quiet child with a respiratory infection can be more alarming than a crying one. With diphtheria, that thick membrane is a ticking time bomb for the airway. Your first job is to be a barrier—protecting every other child on the unit through strict isolation. Your second job is to be a hawk-eyed guardian, watching for the slightest sign that the airway is closing. In scenarios like this, NCLEX isn't just testing knowledge; it's testing your nursing instinct for what is most dangerous right now. Always think: What will kill my patient first? Contagion and a closed airway are the answers here. Master that thought process, and you'll master priority questions."
