A 6-year-old child is diagnosed with scarlet fever. Which nursing intervention should be implemented first?

Contact and droplet precautions must be implemented immediately to prevent transmission of group A streptococcus. Other interventions are secondary to infection control.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for a child with Scarlet fever. Scarlet fever is caused by infection with Group A Streptococcus (GAS) bacteria, specifically strains that produce an erythrogenic toxin. The primary mode of transmission is through respiratory droplets (e.g., coughing, sneezing) and contact with contaminated surfaces or secretions. The core principle here is Key Point! Infection control and prevention of disease transmission take precedence over symptomatic management in a communicable disease. This aligns with the nursing process and public health safety standards.

Answer Rationale: The correct answer is to Initiate contact precautions and droplet precautions immediately. This is the first and most critical action because: 1. Key Point! Scarlet fever is highly contagious. Implementing isolation precautions immediately upon diagnosis or suspicion is a standard public health and infection control mandate to protect other patients, healthcare workers, and visitors. 2. The causative agent, Group A Streptococcus, can lead to serious complications like Acute rheumatic fever (ARF) and Post-streptococcal glomerulonephritis (PSGN). Preventing its spread is crucial. 3. In the nursing process, ensuring safety (in this case, public health safety) is always a top priority before addressing comfort measures.

Distractor Analysis: - Watch out for confusion! Option ② (Administer acetaminophen): While fever management is important for patient comfort and preventing febrile seizures, it is a supportive intervention. It does not address the immediate risk of disease transmission. - Watch out for confusion! Option ③ (Encourage fluids): Maintaining hydration is vital, especially with fever, but it is again a secondary comfort and supportive measure. The priority is to contain the pathogen. - Watch out for confusion! Option ④ (Apply cool compresses): This addresses the symptomatic skin irritation from the characteristic "sandpaper" rash. It is a comfort measure and is the least urgent action among the choices.

Related Concepts: The principle of transmission-based precautions is fundamental. For airborne diseases (e.g., tuberculosis, measles), Airborne Infection Isolation Room (AIIR) and N95 respirators are required. For droplet diseases (like scarlet fever, influenza, pertussis), a private room or cohorting and surgical masks are standard. Contact precautions (gown, gloves) are added when there is risk of contact with infectious secretions (e.g., draining wounds, uncontrolled secretions). Concept Summary

Impetigo	Contact	Contact Precautions	Honey-colored crusted lesions, often Staphylococcus aureus

Anatomy, Physiology & Pharmacology Points - Pathophysiology: GAS bacteria release exotoxins. The erythrogenic toxin causes capillary damage, leading to the diffuse erythematous rash and enanthem (strawberry tongue). - Pharmacology: Penicillin (or Amoxicillin) is the drug of choice. A full 10-day course is crucial even if symptoms improve, to eradicate the bacteria and prevent Acute rheumatic fever (ARF). For penicillin-allergic patients, Erythromycin or Azithromycin may be used. - Immunology: The rash is a hypersensitivity reaction to the toxin, not a direct effect of bacterial invasion. Memory Tips - Precaution Priority: Remember "Stop the Spread First" (Scarlet fever = Stop Spread First with precautions). - Symptoms: Think "RASH TOY": Rash (sandpaper), After strep throat, Strawberry tongue, High fever / Toxin-mediated, Oral pallor (circumoral), Young children (common age). - Complications: Remember the "Post-Strep" problems: PSGN (Glomerulonephritis) and ARF (Rheumatic Fever). High-Frequency NCLEX Topics NCLEX frequently tests priority-setting and infection control. For any communicable disease, the first nursing action is almost always to initiate appropriate precautions. Expect questions on differentiating transmission routes (Airborne vs. Droplet vs. Contact) and identifying the correct personal protective equipment (PPE). Knowing the classic presentation of childhood exanthems (rashes) is also a common theme. Watch Out for Question Variations! - Instead of asking for the "first intervention," the question could ask: "The nurse is preparing a room for a child with suspected scarlet fever. Which action is most appropriate?" (Answer: Place the child in a private room and have staff wear a surgical mask and gown/gloves upon entry). - The question could shift to patient/family education: "Which instruction is most important for the parents of a child with scarlet fever?" (Answer: Complete the entire course of antibiotics even if the child feels better, to prevent rheumatic fever). - It could be integrated into a medication question: "A child with scarlet fever is prescribed penicillin. The parent states the child had a rash with amoxicillin. What is the nurse's priority action?" (Answer: Hold the dose and notify the provider, as there is a potential cross-reactivity; patient safety regarding drug allergy is the priority).

Nursing Clinical Practice Guide Clinical Scenario: You are a nurse in a pediatric clinic. A 6-year-old boy is brought in with a sore throat, fever of 102.5°F (39.2°C), and a bright red, sandpaper-like rash on his trunk and extremities. His tongue appears red with prominent papillae (strawberry tongue). A rapid strep test is positive.

Nursing Intervention Strategy: 1. Immediate Action (Priority): Upon confirmation or strong suspicion, immediately escort the child and family to a private examination room. Don appropriate PPE: a surgical mask and gloves. If significant secretions are present, add a gown. Place a surgical mask on the child if tolerated during transport. Place a "Droplet & Contact Precautions" sign on the door. 2. Assessment: Perform a focused assessment while maintaining precautions. Assess vital signs, characteristics of the rash, hydration status (skin turgor, mucous membranes, urine output), and pain level (from sore throat). 3. Collaboration & Treatment: Administer the first dose of prescribed antibiotic (e.g., penicillin) as soon as possible, often in the clinic if an injection is ordered, to rapidly reduce contagion and start preventing complications. Educate the family on the importance of completing the full course. 4. Supportive Care: After isolation is secured, implement comfort measures: administer antipyretics (acetaminophen/ibuprofen) as ordered, encourage cool fluids and soft foods, and advise on soothing skin care (e.g., lukewarm baths, soft clothing, avoid scratching). 5. Education & Discharge Planning: Teach that the child is considered contagious until 24 hours after starting effective antibiotic therapy. They should not return to school/daycare before this period. Instruct on hand hygiene, covering coughs, and not sharing utensils. Discuss signs of complications to report: dark cola-colored urine (glomerulonephritis), joint pain/swelling, or new fever (rheumatic fever).

Patient Safety and Precautions: - PPE Doffing: Remove PPE in the correct order (gloves first, then gown, then mask) and perform hand hygiene immediately after leaving the room. - Medication Safety: Verify any drug allergies, especially to penicillin. Observe for 15-30 minutes after the first dose if given in the clinic. - Reporting: Scarlet fever is a reportable disease in many jurisdictions. The nurse may be responsible for initiating the report to the local health department. Nursing Procedure & Medication Flow Procedure: Initiating Droplet & Contact Precautions 1. Identify the need based on diagnosis/symptoms. 2. Place patient in a private room. If not available, consult infection control for cohorting with same infection. 3. Post clear signage on the door. 4. Don PPE before room entry: Perform hand hygiene → Put on gown → Put on mask → Put on gloves. 5. Limit patient transport. If essential, have patient wear a surgical mask. 6. Dedicate equipment if possible. Clean and disinfect shared equipment. 7. Remove PPE at point of exit: Remove gloves → Remove gown → Perform hand hygiene → Remove mask → Perform hand hygiene.

Medication: Penicillin Administration - Route: Often IM (Benzathine penicillin G) for one-dose compliance, or oral (Penicillin V) for 10 days. - Key Education: "Finish all the medicine, even if your child feels all better in a few days. Stopping early can let the strep bacteria come back and cause serious heart or kidney problems." - Monitoring: Observe for allergic reaction (rash, difficulty breathing). For oral form, monitor for GI upset; administer with food if needed. A Word from Your Senior Nurse "In the real world, infection control can feel like a hassle, but it's the bedrock of safe nursing practice. That moment you put on gloves and a mask isn't just about protocol—it's a barrier of protection for your vulnerable patients in the next room and for yourself. With kids, parents are often anxious about the rash and fever. While you address those concerns, never underestimate the power of clear, calm education about preventing spread to siblings and completing antibiotics. Mastering these priorities—safety first, then comfort, then education—is what makes a nurse truly effective. On the NCLEX and at the bedside, always think: 'What protects the patient and the public FIRST?'"
