1 Endocrine Assessment and Nursing Foundations Free Online FlashCards

What role do hormones play in the endocrine system?

Hormones are chemical messengers released into the bloodstream that coordinate processes such as metabolism, growth, stress responses, and fluid balance.

How does negative feedback regulate thyroid hormone levels?

As thyroid hormone levels rise, signaling that drives TSH release decreases. This negative feedback helps regulate thyroid hormone production.

Why should hormone test results be interpreted in context?

Interpret hormone results in context: time of day, illness, stress, medication use, and other physiologic conditions can affect levels.

What elements make up a focused endocrine assessment?

A focused assessment combines the patient’s history, physical findings, medication review, and relevant laboratory results.

Why review a patient’s medicines and supplements during endocrine assessment?

Review prescription and nonprescription medicines and supplements, including how the patient takes them; some can affect hormone levels or test interpretation.

Why should thyroid assessment extend beyond the neck?

Thyroid disorders can affect many body systems. Connect symptoms with findings such as heart-rate or weight changes rather than assessing the neck alone.

What should a nurse confirm before collecting an endocrine test sample?

Confirm the ordered test and its preparation requirements, including fasting, collection time, medication instructions, and timed specimen collection. Clarify uncertainties before collecting.

How do A1C and fasting plasma glucose differ?

A1C reflects average glucose over roughly three months; fasting plasma glucose is a point-in-time measurement.

Can a home glucose-meter result by itself diagnose diabetes?

No. Diabetes diagnosis uses appropriate laboratory testing and clinical criteria; home glucose monitoring supports ongoing care.

What thyroid conditions commonly accompany high versus low TSH?

A high TSH commonly accompanies primary hypothyroidism, while a low TSH commonly accompanies hyperthyroidism. Interpret TSH with thyroid hormone results and clinical context.

What does an ACTH stimulation test assess?

An ACTH stimulation test assesses whether the adrenal glands increase cortisol production in response to stimulation.

What is an important nursing precaution when cortisol testing is planned?

Record steroid exposure and follow the prescriber’s instructions. Do not independently stop prescribed steroids for testing.
