Study Notes on Medications and Health Issues

Considerations in Medications and Health

Social Determinants of Health

  • Importance in Chronic Diseases:

    • Social determinants play a significant role in chronic disease management.
    • Economic factors, particularly for older adults on fixed incomes, affect access to medications and healthful foods.

  • Impact of Financial Constraints:

    • Many older adults may not afford their prescriptions, resulting in discontinuation and exacerbation of health issues.
    • Example: Patients may present in emergency rooms with severe hypertension (e.g., blood pressure of 180/100) due to missed medications.

  • Challenges of Healthy Eating:

    • Healthy foods (fruits, vegetables, lean meats) are often more expensive than less nutritious options.
    • Economic inequality can lead to inadequate nutrition, impacting overall well-being.

  • Environmental Factors:

    • Patients in unsafe neighborhoods may find it challenging to adhere to exercise recommendations, such as walking after work.
    • Healthcare providers should remain sensitive to these limitations when treating patients.

Medication Adherence Factors

  • Key Factors Affecting Adherence:
    • Food insecurity, housing instability, and insufficient income are major obstacles in adhering to prescribed medication regimens.

Lifespan Considerations in Medication Management

  • Considerations for Different Age Groups:

    • Discussed age groups: pregnancy, infants (up to 1 year), children (1-12 years), and older adults (61+).

  • Teratogenic Medications:

    • Definitions: Medications that can cause harm or developmental defects in a fetus during pregnancy. Common issues include limb malformations and other developmental defects.
    • First Trimester Risks: High risk for developmental issues during the first trimester when fetal development is critical.
    • Third Trimester Risks: Greater absorption of substances occurs as the fetus grows, necessitating caution in medication usage.
    • Categories of Medication Risk During Pregnancy:
    • Category A: No known risk in humans (extremely rare).
    • Category B: No risk in animals and humans; safe examples include acetaminophen (Tylenol).
    • Category C: Potential risk shown in animal studies; benefits may outweigh risks (e.g., steroids for severe asthma).
    • Category D: known risks of adverse outcomes; usage is only justified in severe cases.
    • Category X: known to cause fetal harm; should not be used during pregnancy.

  • Breastfeeding Considerations:

    • Nurses should refer patients to pediatricians for medication guidance while nursing.

Pediatric Medication Guidelines

  • Dosage Differences:
    • Infants are categorized as up to 1 year and children from 1-12 years. Dosages vary based on age and weight.
