Are you preparing for the NCLEX exam and feeling overwhelmed by the vast amount of information you need to know? Don’t worry — we’ve got you covered! This article provides a comprehensive review of endocrine disorders, including pathophysiology, signs and symptoms, and nursing management strategies.
By the end of this article, you’ll feel more confident and prepared to tackle any NCLEX questions related to the endocrine system.
Introduction to Endocrine Disorders
The endocrine system plays a vital role in maintaining homeostasis in the body. It consists of glands that produce hormones — chemical messengers that regulate key functions such as metabolism, growth, mood, and reproduction.
When hormone levels become imbalanced, it can lead to a variety of endocrine disorders, many of which are commonly tested on the NCLEX. Understanding these disorders is critical to both safe patient care and exam success.

Common Endocrine Disorders
1. Diabetes Mellitus
Diabetes mellitus is one of the most commonly tested NCLEX topics and a major cause of chronic illness worldwide.

- Type 2 Diabetes: Insulin resistance and relative insulin deficiency.
Signs and Symptoms:
- Polyuria, polydipsia, polyphagia
- Fatigue, blurred vision, slow wound healing
Nursing Management:
- Blood glucose monitoring

3. Hyperthyroidism
Pathophysiology:
Most commonly caused by Graves’ disease, which leads to overstimulation of the thyroid.
Signs and Symptoms:
- Heat intolerance, weight loss, anxiety
- Tachycardia, palpitations, insomnia
Nursing Management:
- Administer antithyroid meds (e.g., methimazole)
- Monitor for thyroid storm
- Provide a low-stimulation environment
4. Addison's Disease
Pathophysiology:
Autoimmune destruction of the adrenal cortex, resulting in insufficient cortisol and aldosterone production.
Signs and Symptoms:
- Fatigue, hypotension, salt craving
- Hyperpigmentation, electrolyte imbalances
Nursing Management:
- Corticosteroid and mineralocorticoid replacement
- Stress-dose steroids for illness or surgery
- Patient education on adrenal crisis recognition
