W6 NR283 Exam 2
A patient with Graves’ disease presents with tachycardia, heat intolerance, and
weight loss. What is the underlying pathophysiology?
A. Decreased TSH production
B. Autoantibody stimulation of thyroid hormone release
C. Destruction of thyroid tissue
D. Impaired iodine uptake
B – Graves’ disease is autoimmune, antibodies stimulate thyroid → ↑ T3/T4.
,A nurse is caring for a patient with hypothyroidism. Which assessment finding is
most concerning?
A. Weight gain
B. Cold intolerance
C. Bradycardia
D. Decreased level of consciousness
D – Decreased LOC = possible myxedema coma (life-threatening).
,A patient with diabetic ketoacidosis (DKA) has a blood glucose of 480 mg/dL.
What is the priority intervention?
A. Administer insulin
B. Start IV fluids
C. Give potassium supplements
D. Administer bicarbonate
B – Fluids FIRST in DKA to restore perfusion before insulin.
, Which mechanism explains polyuria in uncontrolled diabetes mellitus?
A. Increased ADH secretion
B. Osmotic diuresis from excess glucose
C. Decreased glomerular filtration rate
D. Increased insulin production
B – Excess glucose pulls water → osmotic diuresis → polyuria.
