Rationale (NURS201 Quiz 5) | West Coast

1. A nurse is reviewing the lab results for a client with suspected SIADH. Which of the
following findings should the nurse expect?
A. Serum sodium of 120 mEq/L
B. Serum osmolarity of 310 mOsm/kg
C. Urine specific gravity of 1.002
D. Increased urinary output
Answer: A
Rationale: SIADH involves the excessive release of antidiuretic hormone, which causes the
body to retain water. This water retention leads to dilutional hyponatremia, typically
reflected by a low serum sodium level. The nurse should monitor for neurological changes
associated with such significant electrolyte imbalances.
2. A client is diagnosed with Cushing’s Syndrome. Which clinical manifestation is a hallmark
sign of this condition?
A. Bronze skin pigmentation
B. Trunkal obesity and moon face
,C. Postural hypotension
D. Weight loss and dehydration
Answer: B
Rationale: Cushing’s Syndrome is characterized by an excess of glucocorticoids, which
causes redistribution of fat to the face and trunk. Other common signs include a buffalo
hump and purple striae on the abdomen. Nurses must assess for these physical changes
and manage the associated hypertension and hyperglycemia.
3. Which intervention is the priority for a nurse caring for a client in an Addisonian crisis?
A. Restricting fluid intake to 1000 mL per day
B. Administering oral glucose for hypoglycemia
C. Monitoring for weight gain
D. Rapid infusion of IV normal saline and hydrocortisone
Answer: D
Rationale: An Addisonian crisis is a medical emergency caused by an acute insufficiency of
adrenal hormones. The priority is to restore fluid volume and provide hormone
replacement to prevent circulatory collapse. Failure to treat this immediately can lead to
shock and death.
, 4. A nurse is teaching a client about taking Levothyroxine for hypothyroidism. Which
instruction is most important?
A. Take the medication on an empty stomach 30-60 minutes before breakfast.
B. Take the medication with a full meal at dinner.
C. Expect the symptoms to resolve within 24 hours.
D. Double the dose if a day of medication is missed.
Answer: A
Rationale: Levothyroxine absorption is maximized when taken on an empty stomach
without other medications or food. Clients should be educated that this is a lifelong therapy
that requires periodic blood monitoring. Taking it at the same time every morning helps
maintain steady hormone levels.
5. A client with Graves’ disease is scheduled for a subtotal thyroidectomy. Which medication
should the nurse expect to administer preoperatively to reduce the vascularity of the thyroid
gland?
A. Levothyroxine
B. Lugol’s solution (iodine)
C. Propylthiouracil (PTU)
D. Calcium gluconate
Answer: B
