Questions and Answers

What are the objectives in the management of hypothyroidism?

Lowering serum cholesterol and preventing atherosclerosis

Increasing oxygen delivery and reducing blood supply

Restoring a normal metabolic state and preventing disease progression and complications (correct)

Enhancing the effects of catecholamines and preventing arrhythmias

What can occur when thyroid replacement is initiated?

Reduced serum cholesterol levels

Angina and acute coronary syndrome (correct)

Improved blood supply

Decreased oxygen demand

Why can a reduction in blood supply be tolerated without overt symptoms of coronary artery disease in patients with hypothyroidism?

The myocardium becomes less sensitive to oxygen deprivation

Blood viscosity decreases in hypothyroid patients

Tissues require relatively little oxygen due to subnormal metabolism (correct)

The heart becomes more efficient in utilizing oxygen

Study Notes

Management and Nursing Care of Hypothyroidism and Myxedema

Discontinuation of thyroid hormone administration is necessary if angina or arrhythmias occur, and cautious, lower dosage resumption with close monitoring is recommended later.
Severe hypothyroidism and myxedema coma require prompt, aggressive management to maintain vital functions, including cautious fluid administration and passive rewarming with a blanket.
Nursing care of patients with hypothyroidism and myxedema should include careful monitoring of the effects of analgesic, sedative, and anesthetic agents, especially in older patients.
Medications for hypothyroidism should be given with extreme caution due to potential altered metabolism and excretion, as well as respiratory status.
Patient and family education is crucial for managing hypothyroidism at home, including proper medication administration, recognizing desired actions and side effects of medications, and the importance of nutrition and diet.
Referral for home, community-based, or transitional care may be indicated, and the nurse should monitor the patient's recovery and ability to cope with changes.
The prevalence of hypothyroidism increases with age, particularly among older women, and may be related to age-related alterations in immune function and multiple comorbidities.
Subclinical disease is common among older women and can be asymptomatic or mistaken for other medical conditions.
Symptoms of hypothyroidism in older adults may be atypical, with subtle symptoms such as fatigue, muscle aches, and mental confusion being attributed to normal aging, requiring close attention.
Signs and symptoms of hypothyroidism in older adults may be atypical and may be mistaken for other conditions, with depression, apathy, decreased mobility, and weight loss being major initial symptoms.
Older patients with severe hypothyroidism and atherosclerosis may become confused and agitated if their metabolic rate is increased too quickly.
Marked clinical improvement follows the administration of hormone replacement, which must be continued for life, with periodic follow-up monitoring of serum TSH levels in older patients.
