,Q1. A nurse is assessing a patient with suspected syndrome of inappropriate antidiuretic hormone
(SIADH). Which laboratory value is most consistent with this condition?
A. Serum sodium 130 mEq/L, serum osmolality 260 mOsm/kg, urine osmolality 600 mOsm/kg
B. Serum sodium 150 mEq/L, serum osmolality 310 mOsm/kg, urine osmolality 100 mOsm/kg
C. Serum sodium 140 mEq/L, serum osmolality 285 mOsm/kg, urine osmolality 300 mOsm/kg
D. Serum sodium 120 mEq/L, serum osmolality 240 mOsm/kg, urine osmolality 50 mOsm/kg
Correct Answer: A. Serum sodium 130 mEq/L, serum osmolality 260 mOsm/kg, urine osmolality
600 mOsm/kg
Rationale: SIADH is characterized by hyponatremia (low serum sodium), low serum osmolality, and
inappropriately concentrated urine (high urine osmolality). Option A shows these findings. Option B
reflects diabetes insipidus (hypernatremia, high serum osmolality, dilute urine). Option C is normal.
Option D shows hyponatremia with dilute urine, which is not consistent with SIADH (urine should be
concentrated).
Why Wrong:
B - This pattern indicates diabetes insipidus, not SIADH, due to hypernatremia and dilute urine.
C - These values are within normal limits and do not support SIADH.
D - Although hyponatremia and low serum osmolality are present, the urine is inappropriately dilute,
ruling out SIADH.

Interprofessional Collaborative Care, 10th Ed., Ch. 17
Q2. A nurse is caring for a patient with a chest tube connected to a dry suction water seal system.
The nurse notes continuous bubbling in the water seal chamber. Which action should the nurse take
first?
A. Tighten all connections and assess for leaks.
B. Clamp the chest tube near the insertion site.
C. Increase the suction pressure setting.
D. Notify the healthcare provider immediately.
Correct Answer: A. Tighten all connections and assess for leaks.
Rationale: Continuous bubbling in the water seal chamber indicates an air leak in the system. The nurse
should first check for loose connections and tighten them. Clamping is avoided unless specifically
ordered, as it can cause tension pneumothorax. Increasing suction may worsen the leak. Notification is
not the first action; the nurse should attempt to resolve the leak.
Why Wrong:
B - Clamping the chest tube is dangerous and reserved for specific orders; it can lead to tension
pneumothorax.
C - Increasing suction does not address an air leak and may increase the leak.
D - The nurse should first attempt to identify and correct the leak before notifying the provider.

, Q3. A nurse is evaluating a patient with chronic kidney disease (CKD) stage 4. Which dietary
restriction is most important for this patient?
A. High potassium intake
B. High phosphorus intake
C. High calcium intake
D. High sodium intake
Correct Answer: B. High phosphorus intake
Rationale: In CKD stage 4, the kidneys cannot excrete phosphorus adequately, leading to
hyperphosphatemia, which stimulates PTH and causes renal osteodystrophy. Restricting phosphorus is
crucial. Potassium restriction may be needed later if hyperkalemia develops, but phosphorus control is
paramount. High calcium is not typically restricted; calcium supplements may be given with phosphate
binders. Sodium restriction is important for blood pressure control but not the most critical dietary
restriction.
Why Wrong:
A - Potassium restriction is important but typically becomes critical in stage 5 or with hyperkalemia.
C - Calcium intake is often supplemented, not restricted, in CKD.
D - Sodium restriction is important for hypertension but not the most crucial dietary restriction.

Problems, 11th Ed., Ch. 46
Q4. A nurse is preparing to administer a blood transfusion to a patient. Which intravenous solution
should be used to prime the blood tubing?
A. 0.9% sodium chloride
B. 5% dextrose in water
C. Lactated Ringer's solution
D. 0.45% sodium chloride
Correct Answer: A. 0.9% sodium chloride
Rationale: Only 0.9% sodium chloride (normal saline) is compatible with blood products. Dextrose
solutions cause hemolysis due to hypotonicity. Lactated Ringer's contains calcium, which can cause
clotting if infused with blood. Hypotonic solutions like 0.45% sodium chloride can also cause hemolysis.
Why Wrong:
B - D5W is hypotonic and causes hemolysis of red blood cells.
C - Lactated Ringer's contains calcium, which can cause clot formation.
D - 0.45% sodium chloride is hypotonic and can cause hemolysis.
