Q&A | WGU
1. A patient is diagnosed with Syndrome of Inappropriate Antidiuretic Hormone (SIADH).
Which laboratory finding should the nurse anticipate?
A. Urine specific gravity of 1.002
B. Serum osmolality of 310 mOsm/kg
C. Serum sodium of 155 mEq/L
D. Serum sodium of 120 mEq/L
Answer: D
Rationale: SIADH involves excessive release of ADH, causing the body to retain too much
water. This fluid retention leads to dilutional hyponatremia, where the serum sodium
levels drop significantly. The nurse should monitor for neurological changes associated
with these low sodium levels.
2. A client with Diabetes Insipidus (DI) is receiving Desmopressin. Which outcome indicates
the medication is effective?
A. Decreased thirst and urine output
B. Increased urine output
C. Decrease in urine specific gravity
,D. Weight loss of 2 pounds
Answer: A
Rationale: Desmopressin acts as a synthetic form of ADH to help the kidneys conserve
water. Successful treatment is characterized by a reduction in the massive polyuria and
polydipsia associated with DI. The nurse should also observe for an increase in urine
specific gravity as a sign of concentrated urine.
3. A nurse is caring for a patient with Cushing’s Syndrome. Which clinical manifestation is
most likely to be observed?
A. Purple striae on the abdomen
B. Weight loss and thin skin
C. Hypotension
D. Hyperkalemia
Answer: A
Rationale: Cushing’s Syndrome is caused by an excess of cortisol, which leads to distinct
physical changes. Purple striae, moon face, and a buffalo hump are classic signs of this
condition. The nurse should also monitor for hyperglycemia and hypertension in these
patients.
4. Which assessment finding is a priority for a patient in Addisonian crisis?
A. Hyperglycemia
, B. Bradycardia
C. Severe hypotension
D. Weight gain
Answer: C
Rationale: Addisonian crisis is a medical emergency caused by an acute insufficiency of
adrenocortical hormones. It typically manifests as profound hypotension, electrolyte
imbalances, and circulatory collapse. Immediate intervention with IV fluids and
glucocorticoids is required to prevent death.
5. A patient with hyperthyroidism is experiencing a thyroid storm. Which intervention is the
nurse’s priority?
A. Administering aspirin for fever
B. Starting a high-calorie diet
C. Providing a warm environment
D. Maintaining a patent airway
Answer: D
Rationale: Thyroid storm is a life-threatening complication characterized by extreme
tachycardia, fever, and altered mental status. Maintaining airway and adequate
oxygenation is always the first priority in emergency nursing care. Aspirin should be
