Physical Assessment
This physical finding, characterized by abnormal protrusion of the eyeballs, is a hallmark sign of Graves' disease caused by retro-orbital tissue inflammation.
What is Exophthalmos?
This is the normal expected reference range for serum sodium, which becomes profoundly diluted in patients experiencing SIADH.
What is 135 to 145 mEq/L?
This life-threatening crisis is the severe, acute manifestation of untreated hypothyroidism, presenting with hypothermia, bradycardia, and profound respiratory depression.
What is Myxedema Coma?
This thyroid replacement hormone must be taken on a completely empty stomach in the morning, 30 to 60 minutes before breakfast.
What is Levothyroxine?
When assessing an infant for congenital hypothyroidism, this classic assessment cue is often noted due to severe generalized myxedematous fluid retention.
What is a Hoarse Cry (or Macroglossia/Enlarged Tongue)?
The nurse elicits this sign by tapping the patient's facial nerve anterior to the earlobe, looking for an involuntary twitch of the lip or facial muscles.
What is Chvostek’s sign?
A urine specific gravity of 1.002 indicates highly diluted urine, commonly seen in patients experiencing this underlying pituitary disorder.
What is Diabetes Insipidus (DI)?
Characterized by a buffalo hump, moon face, purple striae, and truncal obesity, this disease stems from an overproduction of cortisol by a pituitary adenoma.
What is Cushing's Disease?
This pituitary medication replaces antidiuretic hormone in patients with Diabetes Insipidus, requiring the nurse to tightly restrict fluid intake to avoid water intoxication.
What is Desmopressin (DDAVP)?
When managing an older adult patient on fludrocortisone, this is the priority nursing assessment to monitor for secondary fluid volume excess.
What is Auscultating Lung Sounds (for crackles) or checking daily weights?
Inflating a blood pressure cuff above systolic pressure for 3 minutes to provoke an involuntary carpopedal spasm tests for this positive assessment finding.
What is Trousseau’s sign?
This is the normal expected reference range for a healthy adult's urine specific gravity.
What is 1.005 to 1.030?
A medical emergency featuring hyperpyrexia, extreme tachycardia, altered mental status, and high-output heart failure due to an abrupt surge of thyroid hormones.
What is Thyroid Storm?
Abruptly stopping this daily medication can trigger a life-threatening Addisonian crisis due to drug-induced adrenal cortex atrophy.
What is Prednisone (or Corticosteroids)?
To provide culturally competent care for a patient requiring Radioactive Iodine (RAI) therapy, the nurse must ensure the patient can arrange this strict logistical restriction safely at home.
What is Isolation from pregnant women/children (or separate bathroom facilities)?
Both Chvostek's and Trousseau's signs indicate severe neuromuscular irritability secondary to a deficit of this specific serum electrolyte.
What is Calcium (Hypocalcemia)?
This is the normal reference range for serum osmolality, which drops below 275 mOsm/kg in SIADH and spikes above 295 mOsm/kg in Diabetes Insipidus.
What is 275 to 295 mOsm/kg?
This parathyroid disorder leads to severe bone resorption, pathological fractures, and renal calculi due to chronic hypercalcemia.
What is Hyperparathyroidism?
Medications like sevelamer hydrochloride and calcium carbonate must be administered exactly at this time to successfully bind dietary phosphorus.
What is With Meals (or with food)?
During a Fluid Deprivation Test, this is the primary clinical indicator that mandates the nurse immediately terminate the test to protect the patient from hypovolemic shock.
What is a loss of >2% of baseline body weight (or severe hypotension)?
When assessing a patient with a known goiter, this is the primary physical assessment technique that the nurse must avoid to prevent a massive release of thyroid hormones.
What is Vigorous or Deep Palpation?
If a patient's cortisol levels fail to rise after administering synthetic ACTH during an ACTH Stimulation Test, it confirms a diagnosis of this disease.
What is Addison's Disease (Primary Adrenal Insufficiency)?
This baseline metabolic test requires a patient to stand or sit upright for a specified time before the draw because its levels are intensely sensitive to gravity and posture.
What is Aldosterone?
This is the primary medication the nurse must keep at the bedside for rapid emergency IV administration following a total thyroidectomy if the patient develops signs of tetany.
What is Calcium Gluconate?
Due to the natural diurnal rhythm of hormone secretion, the nurse must ensure a baseline serum cortisol test is drawn at this specific time of day to capture peak physiological levels.
What is Early Morning (approx. 06:00 AM – 08:00 AM)?
