    Study Notes

    Medical Surgical Nursing (MSN) 2 - Thyroid Gland

    • Course title: Medical Surgical Nursing
    • Course level: 2
    • Topic: Thyroid Gland
    • Lecturer: Ns. Jon Parulian Simarmata M. Kep.
    • University: Universitas Pelita Harapan (UPH)

    Sub-Competency Measurement Criteria (CPMK)

    • Holistic Nursing Care: Apply principles of holistic nursing care in lab and clinical practice for patients with thyroid disorders.
    • Assessment, Diagnosis, Intervention, Implementation, and Evaluation: Formulate appropriate and systematic assessment, diagnosis, intervention, implementation, and evaluation of nursing care for patients with thyroid disorders.
    • Evidence-Based Practice: Interpret and apply evidence-based practice in nursing care for patients with thyroid disorders.

    Endocrine System

    • The endocrine system is a complex network of glands producing hormones regulating various bodily functions.
    • Diagram shows the hypothalamus, pituitary gland, thyroid and parathyroid glands, pancreas, adrenal glands, ovaries (female), testes (male), and placenta.

    Thyroid Gland Anatomy

    • Location: Butterfly-shaped gland in the neck, below the larynx.
    • Structure: Two lobes connected by an isthmus. Parathyroid glands located behind the thyroid.
    • Diagram: Provides a clear anatomical view of the thyroid gland from both front and back perspectives, showing the relation to the larynx, trachea, and parathyroid glands.

    Thyroid Gland Function

    • Regulates metabolic processes throughout the body which includes:
      • Body growth and cell maturation
      • Development of nervous system in infants and children
      • Cardiovascular and respiratory function throughout life
      • Increasing metabolism of protein, fat, and glucose leading to increased heat production and oxygen demand.
      • Optimizing the functioning of other hormones and neurotransmitters

    Thyroid Disorders - Hyperthyroidism

    • General: The most common form is Graves' disease
    • Metabolic state: Condition with excessive metabolic activity.
    • Hormone levels: Increased levels of T3 and T4.
    • Symptoms: Include weight loss, increased appetite, heat intolerance, insomnia, irritability, nervousness, tremors etc.
    • Types:
      • Primary: directly related to disorders of the thyroid gland
      • Secondary: due to disorders affecting the pituitary gland.
    • Causes: Graves' disease, Toxic multinodular goiter (TMG), Toxic adenoma, thyroiditis (inflammation of the thyroid gland.

    Specific to Graves' Disease

    • Prevalence: Women are more commonly affected (higher ratio)
    • Cause: Autoimmune disease; antibodies trigger excessive thyroid hormone production.
    • Symptoms: Enlargement of the thyroid gland, eye changes, and skin changes (edema, exophthalmos, etc).

    Specific to TMNG

    • Prevalence: More common in older adults
    • Symptoms: Milder manifestations compared to Graves' disease. Elevation of FT4 and FT3. Clinically multiple nodules are common, firm nodules/plowers and hot and normal areas detected in the scintigraphy
    • Cause: Multiple nodules within the thyroid gland leading to increased thyroid hormone production.

    Subacute Thyroiditis

    • Cause: Inflammation related to viral infections.
    • Characteristics: Characterized by pain in the front of the neck, tender and enlarged thyroid gland that goes through periods with excessive and suppressed hormone levels
    • Symptoms: Painful thyroid gland, elevated temperature

    Toxic Single Adenoma (TSA)

    • Cause: Single nodule within the thyroid gland causing increased thyroid hormone production.
    • Symptoms: Typically is associated with a more defined painful nodule/region.

    Age and Sex Differences

    • Graves' disease tends to affect patients between 20 and 40 years old and is more common in females.
    • Other types of disorders may have different age ranges

    Diagnosis Tests

    • TSH measurements: Highly suppressed TSH (<0.05 μIU/mL)
    • Serum T3 and T4 levels: Increased levels are common
    • Thyroid Antibodies (anti-TPO,TSI): Present in some cases
    • EKG for heart conditions
    • Nuclear scintigraphy to assess thyroid function

    Treatment

    • Medications: Anti-thyroid drugs such as methimazole, carbimazole, and propylthiouracil (PTU), Radio-active iodine treatment, corticosteriods and NSAIDs.
    • Surgery: Thyroidectomy (subtotal or total, lobectomy).

    Nursing Care Management for Hyperthyroidism

    • First Step: Rehydration
    • Supportive Measures: Managing symptoms associated with cardiac distress and preventing complications
    • Pharmacological Interventions: Medication Administration and Management
    • Monitoring: Monitoring cardiac and metabolic function and symptoms
    • Nutrition: Providing nutritional guidance for managing symptoms and complications

    Differential Diagnosis - Hypothyroidism

    • Definition: Low levels of thyroid hormones (T3 and T4).
    • Cause: Resulting either from decreased thyroid hormone production or reduced release of thyroid hormones (from hypothalamus, pituitary or thyroid gland)
    • Symptoms: Fatigue, cold intolerance, weight gain, constipation, reduced heart rate, and depression amongst others and some can be seen from the reproductive standpoint

    Hypothyroidism - Types and Causes

    • Types: Primary (directly related to problems of the thyroid gland), and Secondary (due to problems from hypothalamus, pituitary, or both)
    • Causes: Thyroiditis (inflammation of the thyroid), Autoimmune disorders, Iodine deficiency, Medications, and possibly pregnancy.

    Hypothyroidism - Clinical Manifestations

    • General Symptoms: Fatigue, intolerance to cold, weight gain, constipation, dry skin.
    • Eye Symptoms: Puffy eyelids.
    • Respiratory Symptoms: Shortness of breath.
    • Cardiovascular Symptoms: Bradycardia.
    • Reproductive Symptoms: Irregular periods (menorrhagia), infertility.
    • Psychological Symptoms: Memory issues, concentration problems, depression, emotional instability.

    Nursing Interventions for Treating Hypothyroidism

    • Management: The goal is to alleviate symptoms with medical intervention (hormonal therapy), lifestyle modification (dietary and activity, stress and sleep management)

    Hypothyroidism - Nursing Assessments

    • Thyroid Gland Assessment: Inspect, palpate, and auscultate the thyroid gland.
    • Medications: Assessing medication records, confirming adherence.
    • Monitoring: Vital signs, especially for heart rate (bradycardia) and others
    • Nutrition: Dietary recommendations for optimal health
    • Symptoms: Gathering and evaluating all symptoms exhibited or relayed by patient.

    Evaluation - Hypothyroidism

    • Goals: Monitor patient's recovery and adaptation.
    • Effectiveness of Treatment: Assess to what degree the treatment regime is alleviating the symptoms and helping the body adapt to the normalization.
    • Patient Participation: Observe for any positive changes in the patient's ability to carry out their daily tasks.
    • Body temperature regulation: Observe for any improvements in body temperature regulation
    • Intestinal function monitoring: Assessing bowel activity and regularity
    • Respiratory status monitoring: Observation of respiratory function to achieve a normal status
