NUR 210 EXAM 3 - ADVANCED NURSING
CONCEPTS QUESTIONS AND ANSWERS
2026/2027
1. A patient with Diabetic Ketoacidosis (DKA) is being treated with an intravenous insulin
infusion. Which laboratory value is the priority for the nurse to monitor to prevent life-
threatening complications?
A. Serum Glucose
B. Serum Potassium
C. Serum Sodium
D. Serum Bicarbonate
Answer: B
Conceptual Explanation: As insulin drives glucose into cells, it also moves potassium into
the intracellular space, which can lead to severe hypokalemia and cardiac arrhythmias.
2. A client presents with a suspected Addisonian crisis. Which of the following sets of
laboratory findings would the nurse most likely expect?
A. Hyperglycemia and Hypokalemia
B. Hyponatremia and Hyperkalemia
C. Hypernatremia and Hypocalcemia
,D. Hypoglycemia and Hypokalemia
Answer: B
Conceptual Explanation: Addison’s disease involves a lack of aldosterone and cortisol,
leading to sodium loss (hyponatremia) and potassium retention (hyperkalemia).
3. A patient is 12 hours post-thyroidectomy. The nurse notes that the patient is experiencing
muscle twitching and a positive Chvostek’s sign. Which medication should the nurse prepare?
A. Potassium Chloride
B. Magnesium Sulfate
C. Sodium Bicarbonate
D. Calcium Gluconate
Answer: D
Conceptual Explanation: Twitching and a positive Chvostek sign indicate hypocalcemia, a
common complication if the parathyroid glands are accidentally damaged or removed
during a thyroidectomy.
4. In a patient with SIADH (Syndrome of Inappropriate Antidiuretic Hormone), which nursing
intervention is the highest priority?
A. Encouraging oral fluid intake
B. Administering rapid IV boluses of Normal Saline
C. Maintaining a strict fluid restriction
, D. Increasing dietary sodium intake alone
Answer: C
Conceptual Explanation: SIADH causes excessive water retention and dilutional
hyponatremia; fluid restriction is the primary treatment to prevent further dilution and
cerebral edema.
5. Which clinical manifestation should the nurse prioritize in a patient diagnosed with
Pheochromocytoma?
A. Profound Bradycardia
B. Severe Hypertension
C. Generalized Edema
D. Extreme Lethargy
Answer: B
Conceptual Explanation: Pheochromocytoma is a catecholamine-secreting tumor of the
adrenal medulla that causes paroxysmal or sustained severe hypertension, which can lead
to stroke.
6. A patient is in the Oliguric phase of Acute Kidney Injury (AKI). The nurse knows that the
patient is at highest risk for which of the following?
A. Hyperkalemia
B. Hypernatremia
