NUR 2502 MULTIDIMENSIONAL CARE
III EXAM 3 REVIEW QUESTIONS AND
ANSWERS
1. A patient with SIADH is experiencing severe hyponatremia. Which intravenous solution
should the nurse expect the healthcare provider to order?
A. 3% Sodium Chloride
B. 0.45% Sodium Chloride
C. Dextrose 5% in Water
D. Lactated Ringer’s
Answer: A
Conceptual Explanation: Hypertonic saline (3% NaCl) is used in severe hyponatremia
associated with SIADH to slowly raise serum sodium levels while monitoring for fluid
overload.
2. Which assessment finding is most characteristic of a patient in the oliguric phase of Acute
Kidney Injury (AKI)?
A. Urine output less than 400 mL/day
,B. Hypokalemia and hypotension
C. Serum creatinine level of 0.8 mg/dL
D. Urine output of 1500 mL/day
Answer: A
Conceptual Explanation: The oliguric phase of AKI is defined by a significant decrease in
urine output, typically less than 400 mL per 24 hours.
3. A patient presents with a TSH of 12.5 mIU/L and a low T4 level. Which clinical
manifestation should the nurse anticipate?
A. Exophthalmos
B. Heat intolerance
C. Weight loss
D. Bradycardia
Answer: D
Conceptual Explanation: High TSH and low T4 indicate hypothyroidism, which slows
metabolic processes, leading to symptoms like bradycardia, constipation, and cold
intolerance.
4. Which medication is the priority for a patient experiencing an Addisonian crisis?
A. Insulin aspart
B. Furosemide
, C. Spironolactone
D. Hydrocortisone sodium succinate
Answer: D
Conceptual Explanation: Addisonian crisis is a life-threatening deficiency of
glucocorticoids; immediate replacement with IV hydrocortisone is required to stabilize the
patient.
5. A patient with Chronic Kidney Disease (CKD) has a potassium level of 6.8 mEq/L. Which
cardiac monitor finding is most concerning?
A. Prominent U waves
B. Tall, peaked T waves
C. Prolonged ST segment
D. Shortened PR interval
Answer: B
Conceptual Explanation: Hyperkalemia (K+ > 5.0) commonly causes tall, peaked T waves
and can progress to lethal arrhythmias if not treated.
6. What is the primary goal of administering Lactulose to a patient with hepatic
encephalopathy?
A. To reduce serum ammonia levels
B. To increase blood glucose levels
