D119: Pediatric Primary Care for the Advanced Practice Nurse

A study guide to WGU's FNP course on primary care for infants, children and adolescents: development, wellness, immunization and common conditions.

Updated October 2026 · 5 min read

D119 prepares FNP students to provide primary care to children from infancy through adolescence, together with their families, in outpatient settings.

WGU's MSN Family Nurse Practitioner program guide says the course develops competence in health promotion and disease prevention, diagnosing and managing acute and chronic conditions in children, and collaborating with children and families on plans that build patient and family self-efficacy. All MSN core and NP core courses are prerequisites.

Pediatrics is organized by age as much as by system. Knowing what is normal at each stage is the foundation for spotting what is not.

Key Concepts Explained

Developmental Surveillance

Each well-child visit checks growth on standard charts and developmental milestones across gross motor, fine motor, language and social domains. Validated screening tools, used at recommended ages, help identify children who need further evaluation.

Immunization and Prescribing

Immunizations follow the current CDC schedule, including catch-up schedules for children who are behind. Pediatric prescribing is usually weight-based, so accurate weight and dose calculation are essential.

Example: A medication is ordered at 10 mg/kg per dose for a child weighing 18 kg. The dose is 10 x 18 = 180 mg. The next checks are that it does not exceed the maximum single or daily dose, and that the concentration and volume make sense for the family to measure at home.

Adolescent Psychosocial Assessment

The HEEADSSS framework (home, education and employment, eating, activities, drugs, sexuality, suicide and depression, safety) structures a confidential adolescent interview, with an explanation of the limits of confidentiality.

Example: A 15-year-old attends for a sports physical. After time with the parent, the NP speaks with the teen alone and works through HEEADSSS. The teen mentions poor sleep and low mood. The plan includes a validated depression screen, sleep guidance and a follow-up visit, with family involvement agreed with the teen.

Partnering with Families

The course stresses plans that build both patient and family self-efficacy. In pediatrics, the family carries out most of the plan, so education must fit their routine, literacy and resources.

Typical Tasks and How to Approach Them

Well-child planAge-specific guidanceCover growth, development, immunizations, nutrition, safety and sleep
Acute illness caseDiagnosis and managementWeigh age, red flags and weight-based dosing
Knowledge questionsMilestones and common conditionsStudy by age band, then by system

Nutrition, Activity and Sleep in Wellness Plans

Two competencies focus on everyday health: healthy environments, behaviors and nutrition, and the place of physical activity and rest. Wellness plans in this course work best when they are specific to age and family routine.

Base recommendations on current guidance from bodies such as the American Academy of Pediatrics, and agree one or two realistic changes with the family rather than a long list.
