Recommended Preventive Care for a Well 4-Year-Old Female
A well-child visit for a 4-year-old female should include vision screening with visual acuity testing, fluoride varnish application, immunization review and administration (particularly MMR and varicella if not completed), developmental surveillance, and anticipatory guidance focused on injury prevention, nutrition, physical activity, and limiting screen time. 1
Vision Screening
Vision screening is mandatory at age 4 years and represents one of the most critical preventive interventions at this visit. 1
- Perform monocular visual acuity testing using HOTV letters or LEA SYMBOLS charts as the preferred method, with the fellow eye covered by an adhesive patch to prevent peeking 2
- Do NOT use Snellen letters, as individual letters are not of equal legibility for this age group 2
- Instrument-based screening (photoscreening or autorefraction) can be offered as an alternative for uncooperative children, though visual acuity testing is preferred when the child can cooperate 1, 2
- Refer immediately after the first failed screening rather than rescreening multiple times, as treatment efficacy for amblyopia decreases steadily after age 3 and becomes ineffective by age 12 2
- The comprehensive eye examination should include ocular history, external inspection of eyes and lids, ocular motility assessment, pupil examination, and red reflex examination 2
Dental Health
Apply fluoride varnish at this visit, continuing the schedule that should have begun at 6 months of age through 5 years 1
Immunizations
Verify completion and administer any outstanding routine childhood immunizations: 1, 2
- MMR (measles, mumps, rubella): The second dose is recommended routinely at age 4-6 years but may be administered during any visit, provided at least 4 weeks have elapsed since the first dose 1
- Varicella vaccine: Should be completed if not already given 1, 2
- DTaP (diphtheria, tetanus, pertussis): The final dose in the series should be given at age ≥4 years 1
- Polio (IPV): A fourth dose is not necessary if the third dose was administered at age 4 years or older 1
- Annual influenza vaccine: Should be administered annually for all children 6 months and older 3
- Hepatitis A and B series: Verify completion 2
Hematocrit/Hemoglobin Screening
- Conduct a risk assessment to determine if hematocrit or hemoglobin screening is needed, particularly if the child did not receive universal screening at 12 months or risk-based screening at 15 and 30 months 1
Developmental Surveillance
- Perform developmental surveillance at this visit, assessing for age-appropriate milestones in gross motor, fine motor, language, and social-emotional domains 1, 4
Anticipatory Guidance: Injury Prevention
Unintentional injuries are the leading cause of death in children, making injury prevention counseling critical: 5
- Car safety: Ensure the child remains in an appropriate car seat or booster seat based on height and weight; car seats should remain rear-facing until 2 years of age or until the height or weight limit is reached 4
- Helmet use: Emphasize helmet use for bicycling and other wheeled activities 5
- Water safety: Discuss supervision around water and swimming lessons 1
- Firearm safety: If firearms are in the home, they should be stored locked and unloaded with ammunition stored separately 5
Anticipatory Guidance: Nutrition and Physical Activity
Provide specific dietary and activity recommendations: 1
- Advocate consumption of a variety of fruits, vegetables, whole grains, dairy products, fish, legumes, poultry, and lean meat 1
- Limit foods high in saturated fats (≤10% of calories per day), cholesterol (≤300 mg per day), and trans-fatty acids 1
- Limit salt intake to 6 g per day 1
- Limit intake of sugar and avoid sugar-sweetened beverages 1, 4
- Juice should be provided only in limited quantities for children older than one year 4
- Recommend at least 60 minutes of moderate to vigorous physical activity daily 1, 5
Anticipatory Guidance: Screen Time
Limit screen time to at most 2 hours per day, as sedentary time should be minimized 1, 4
- Screen time should be avoided with the exception of video chatting in children younger than 18 months, and limited to one hour per day for children 2-5 years of age 4
Tobacco Exposure Screening
Screen for tobacco smoke exposure by asking if the child lives with anyone who uses tobacco, if anyone smokes in the home or car, and if caregivers use tobacco products 2
- Provide tobacco use prevention counseling, as messages should start when children are developmentally ready to understand them, typically around age 5 2
Blood Pressure Measurement
- Measure blood pressure annually using proper technique with an appropriately sized cuff 5
- If blood pressure is elevated (≥90th percentile), recommend lifestyle interventions and recheck in 6 months 5
Common Pitfalls to Avoid
- Do not skip vision screening at this age—it is one of the most evidence-based preventive interventions, and delayed detection of amblyopia results in permanent visual impairment 2
- Do not rescreen multiple times for failed vision tests—refer immediately after the first failure 2
- Do not use Snellen letters for visual acuity testing in 4-year-olds; use HOTV or LEA SYMBOLS instead 2
- Ensure proper eye occlusion during visual acuity testing to prevent peeking, which produces false-negative results 2
- Do not defer fluoride varnish application—it should continue through age 5 years 1
