Chapter 43: Infectious Disorders in Children Nursing Care

Infectious Disorders in Children Nursing Care extensive chapter provides a comprehensive guide for maternal and child health nursing professionals regarding infectious disorders in the pediatric population, transitioning from discussions of normal development to addressing the physical and psychosocial effects of illness. It firmly establishes the principles of epidemiology and the chain of infection, detailing the necessary components for disease transmission: the reservoir, portal of exit, mode of transmission (direct, indirect via fomites, or vectors), portal of entry, and the susceptible host. Breaking this chain is presented as the most effective method for infection prevention, heavily supported by the use of Standard Precautions and specific Transmission-Based Precautions (airborne, droplet, contact). The text outlines the progression of infectious diseases through four stages: incubation, the highly contagious prodromal period characterized by nonspecific symptoms, the illness stage with specific manifestations (like exanthems on the skin or enanthems on mucous membranes), and the convalescent period as the child returns to wellness. A major emphasis is placed on the nurse's role in achieving Healthy People 2030 goals, primarily through promoting immunization to prevent vaccine-preventable diseases and educating families on household infection control. The chapter explores the biological defense system, contrasting the rapid, nonspecific innate immunity (involving neutrophils and macrophages) with the targeted adaptive immunity mediated by T cells and B cells. Nursing care utilizing the QSEN competencies is detailed across both outpatient settings (focusing on history, triage, and education using the teach-back method) and inpatient management (monitoring status, symptom relief, and thoughtful planning for children under isolation to prevent social isolation). Numerous specific viral diseases are covered, including common childhood exanthems like roseola and fifth disease (Parvovirus B19), the highly contagious rubeola (measles) marked by Koplik spots, varicella (chickenpox) and its latent form herpes zoster (shingles), and infectious mononucleosis (EBV). The emergence of novel infections is highlighted through the discussion of COVID-19, explaining its mechanism of action, milder presentation in children, and the associated complication of multisystem inflammatory syndrome in children (MIS-C), alongside the importance of a global response to pandemics. Key bacterial diseases addressed include scarlet fever (noted for its sandpaper rash and strawberry tongue), localized skin infections like impetigo and the risk posed by resistant strains like MRSA, and life-threatening infections such as pertussis (whooping cough), diphtheria, and tetanus (lockjaw). Finally, the text describes vector-borne diseases like Lyme disease (with its characteristic erythema migrans rash) and Rocky Mountain Spotted Fever, along with common parasitic and fungal infestations such as head lice (pediculosis), scabies, pinworms (enterobiasis), and ringworm (tinea corporis).
