Questions and Answers

What are the objectives in the management of hypothyroidism?

Increase serum cholesterol and atherosclerosis

Restore a normal metabolic state by replacing the missing hormone and prevent disease progression and complications (correct)

Enhance the cardiovascular effects of catecholamines

Reduce blood supply to the myocardium

Why is prevention of cardiac dysfunction important in hypothyroidism management?

Thyroid hormone replacement increases oxygen demand, which can exceed blood supply leading to angina and acute coronary syndrome (correct)

Thyroid hormone replacement reduces serum cholesterol and atherosclerosis

Thyroid hormone replacement decreases oxygen demand, which can exceed blood supply leading to angina and acute coronary syndrome

Thyroid hormone replacement has no effect on oxygen demand or blood supply

What can occur when thyroid replacement is initiated?

Decrease in serum cholesterol and atherosclerosis

Improved oxygen delivery to the myocardium

Reduction in blood supply to the myocardium

Angina or arrhythmias due to enhanced cardiovascular effects of catecholamines (correct)

Study Notes

Hypothyroidism and Myxedema Management and Nursing Care

Discontinuation of thyroid hormone administration is necessary if angina or arrhythmias occur, with cautious resumption at a lower dosage and close monitoring when it can be safely resumed.
Severe hypothyroidism and myxedema coma require aggressive management to maintain vital functions, including cautious fluid administration and passive rewarming.
Patients with hypothyroidism experience prolonged effects of analgesic, sedative, and anesthetic agents, with older patients at increased risk due to age-related changes in liver and renal function.
Medications for hypothyroidism are given with extreme caution due to potential altered metabolism and excretion, and respiratory status must be monitored.
Patients and families require education and support to manage hypothyroidism at home, including instructions on medication administration, self-care, and the importance of nutrition and diet.
Referral for home, community-based, or transitional care may be indicated, with the nurse monitoring recovery and the patient's ability to cope with changes.
The prevalence of hypothyroidism increases with age, especially among women, and may be related to age-related alterations in immune function and multiple comorbidities.
Older patients with hypothyroidism may present with atypical and subtle symptoms, often mistaken for other medical conditions, and thyroid hormone replacement must be started with low dosages and increased gradually to prevent serious cardiovascular side effects.
Rapid thyroid replacement in older patients with coronary artery disease may lead to angina, worsening heart failure, and tachyarrhythmias, while dementia may become more apparent during early thyroid hormone replacement.
Severe hypothyroidism and atherosclerosis in older patients may lead to confusion and agitation if their metabolic rate is increased too quickly.
Clinical improvement follows hormone replacement, which must be continued for life, with periodic follow-up monitoring of serum TSH levels in older patients to ensure adherence and proper medication intake.
Nursing care of patients with hypothyroidism and myxedema includes monitoring for adverse effects of medications, assessing physical and cognitive status, and documenting subtle signs and symptoms for the primary provider.
