Introduction
This comprehensive assessment is designed to evaluate nursing knowledge and clinical decision-making skills essential for successful practice. The
exam covers critical subject areas including patient safety, pharmacological interventions, health promotion, psychosocial support, and
physiological management. Questions utilize multiple-choice and scenario-based formats that mirror real-world clinical situations, emphasizing
the application of theoretical knowledge to practical decision-making. Candidates will demonstrate competency in prioritization, delegation,
assessment, and intervention strategies. The test bank prepares nursing professionals for high-stakes licensing examinations by focusing on
evidence-based practice, regulatory compliance, ethical standards, and patient-centered care across diverse healthcare settings.
SECTION ONE: QUESTIONS 1–100
Question 1
A nurse is caring for a client with diabetes mellitus who reports blurred vision and increased thirst. Which finding should the nurse prioritize?
A. Blood glucose level of 250 mg/dL
B. Blood pressure of 138/86 mmHg
C. Heart rate of 88 beats/min
D. Temperature of 98.9°F (37.2°C)
🟢 A. Blood glucose level of 250 mg/dL
🔴 RATIONALE: Elevated blood glucose (250 mg/dL) explains the client's symptoms of blurred vision and increased thirst, indicating
hyperglycemia that requires immediate intervention to prevent diabetic ketoacidosis or hyperosmolar hyperglycemic state.
,Question 2
The nurse is administering a blood transfusion. Which action should the nurse take FIRST if the client develops chills and back pain?
A. Stop the transfusion immediately
B. Notify the healthcare provider
C. Check the client's vital signs
D. Administer antihistamines
🟢 A. Stop the transfusion immediately
🔴 RATIONALE: Back pain and chills during transfusion indicate a possible hemolytic reaction, the most serious transfusion reaction. Stopping the
transfusion immediately prevents further infusion of incompatible blood and potential kidney damage or death.
Question 3
A client with chronic obstructive pulmonary disease (COPD) has an oxygen saturation of 88% on room air. What is the appropriate nursing action?
A. Administer oxygen at 2-4 L/min via nasal cannula
B. Increase oxygen to 6 L/min immediately
C. Place the client in supine position
D. Encourage deep breathing exercises only
🟢 A. Administer oxygen at 2-4 L/min via nasal cannula
🔴 RATIONALE: Clients with COPD require controlled oxygen therapy (2-4 L/min) to prevent CO2 retention and respiratory depression while
maintaining adequate oxygenation. Higher flow rates may suppress the hypoxic drive to breathe.
Question 4
Which medication requires routine monitoring of platelet count in a client receiving anticoagulant therapy?
A. Warfarin
B. Heparin
C. Aspirin
D. Clopidogrel
🟢 B. Heparin
,🔴 RATIONALE: Heparin can cause heparin-induced thrombocytopenia (HIT), a serious adverse effect characterized by decreased platelet count.
Routine platelet monitoring is essential during heparin therapy to detect HIT early.
Question 5
A nurse is caring for a postoperative client. Which assessment finding indicates the most immediate concern?
A. Pain score of 6/10
B. Urine output of 20 mL/hr
C. Incisional drainage of 50 mL
D. Respiratory rate of 22 breaths/min
🟢 B. Urine output of 20 mL/hr
🔴 RATIONALE: Normal urine output should be at least 30 mL/hr. Output of 20 mL/hr indicates potential kidney dysfunction, hypovolemia, or
shock, requiring immediate intervention to prevent acute kidney injury.
Question 6
The nurse is teaching a client about iron supplementation. Which statement by the client indicates understanding?
A. "I will take iron with milk for better absorption."
B. "I will take iron with orange juice on an empty stomach."
C. "I will avoid vitamin C while taking iron."
D. "I will take iron with antacids if胃部不适 occurs."
🟢 B. "I will take iron with orange juice on an empty stomach."
🔴 RATIONALE: Vitamin C (orange juice) enhances iron absorption, and taking iron on an empty stomach maximizes absorption. Milk, antacids,
and calcium interfere with iron absorption.
Question 7
A client with heart failure is prescribed furosemide. Which laboratory value requires monitoring?
, A. Sodium
B. Potassium
C. Calcium
D. Magnesium
🟢 B. Potassium
🔴 RATIONALE: Furosemide is a loop diuretic that causes potassium loss, leading to hypokalemia. Monitoring potassium is critical to prevent
cardiac dysrhythmias and muscle weakness associated with low potassium levels.
Question 8
Which client should the nurse assess FIRST after receiving change-of-shift report?
A. Client with pneumonia and oxygen saturation of 94%
B. Client with chest pain and ST-segment elevation
C. Client with diabetes and blood glucose of 180 mg/dL
D. Client with hypertension and blood pressure of 150/90 mmHg
🟢 B. Client with chest pain and ST-segment elevation
🔴 RATIONALE: ST-segment elevation indicates acute myocardial infarction, a life-threatening emergency requiring immediate intervention to
restore coronary blood flow and prevent permanent heart damage.
Question 9
A nurse is caring for a client with a nasogastric tube. Which action is appropriate for maintaining tube patency?
A. Flush with 30 mL normal saline every 4 hours
B. Clamp the tube for 2 hours after feeding
C. Irrigate with tap water every 8 hours
D. Remove and reinsert the tube daily
🟢 A. Flush with 30 mL normal saline every 4 hours
🔴 RATIONALE: Regular flushing with normal saline maintains NG tube patency and prevents clogging. Tap water may cause electrolyte imbalance,
and clamping removes the purpose of the tube.
