2026 PN NCLEX BOARD EXAM (NCSBN) – 200 PRACTICE QUESTIONS
NGN-STYLE CLINICAL JUDGMENT & DETAILED RATIONALES
DOCUMENT OVERVIEW
• Comprehensive 200-question practice bank featuring NGN-style clinical
judgment scenarios that mirror actual NCLEX PN exam format with detailed
rationales for every correct answer
• Study approach: Work through questions by topic area, focus on rationales to
understand the "why" behind each answer, practice time management by
completing 40-50 questions per study session, and review all incorrect answers
immediately with full rationale explanations
QUESTIONS BEGIN
QUESTION 1
A 65-year-old male client with a history of hypertension reports chest pain
and shortness of breath. The nurse notes diaphoresis and anxiety. Which
action should the nurse take FIRST?
A) Administer aspirin 325 mg orally
B) Place client on continuous cardiac monitoring
C) Establish intravenous access
D) Obtain a 12-lead electrocardiogram
E) Call the emergency response team
CORRECT ANSWER: E) Call the emergency response team
,RATIONALE: In this acute clinical situation presenting with classic signs of acute
coronary syndrome (chest pain, shortness of breath, diaphoresis, anxiety), the first
priority is to activate emergency response and notify the physician immediately.
While monitoring, IV access, aspirin, and ECG are all important interventions, they
must follow after calling for help. Activating the emergency response team ensures
immediate physician notification and mobilization of resources. The 12-lead ECG
should be obtained simultaneously but not before or instead of calling for
emergency assistance. This follows the principle of stabilization and obtaining
appropriate help before independent nursing interventions.
QUESTION 2
A nurse is caring for a 78-year-old client with COPD who is experiencing an
acute exacerbation. The client's oxygen saturation is 88% on room air. Which
intervention is MOST appropriate?
A) Encourage deep breathing and coughing exercises
B) Administer high-flow oxygen at 6-8 L/min immediately
C) Place client in Trendelenburg position
D) Administer oxygen at 2-3 L/min via nasal cannula
E) Position client flat in bed
CORRECT ANSWER: D) Administer oxygen at 2-3 L/min via nasal cannula
RATIONALE: Clients with COPD have chronically elevated CO2 levels and their
respiratory drive is stimulated by hypoxemia rather than hypercapnia. If high-flow
oxygen is administered, it removes the hypoxic drive to breathe, potentially causing
respiratory depression. The appropriate intervention is to administer low-flow
oxygen (2-3 L/min) to increase oxygen saturation to an acceptable level (90% or
above) without eliminating the hypoxic respiratory drive. High-flow oxygen is
contraindicated in COPD unless the client is on mechanical ventilation or in severe
respiratory failure requiring intubation. The other positions and breathing exercises
are supportive but do not address the primary concern of safely increasing
oxygenation.
,QUESTION 3
A client is admitted to the unit with diabetic ketoacidosis (DKA). Blood glucose
is 450 mg/dL, pH is 7.2, and HCO3 is 12 mEq/L. Which nursing intervention is
the PRIORITY?
A) Administer regular insulin intravenously
B) Establish intravenous access and initiate normal saline infusion
C) Perform fingerstick glucose checks every 15 minutes
D) Insert an indwelling urinary catheter
E) Administer sodium bicarbonate
CORRECT ANSWER: B) Establish intravenous access and initiate normal saline
infusion
RATIONALE: In DKA, the priority is fluid resuscitation to correct severe dehydration
and restore circulating volume. Clients with DKA lose significant fluid due to
osmotic diuresis and need rapid IV hydration with normal saline. While insulin
administration is crucial, it should follow establishment of IV access and initiation of
fluids. Administering insulin without adequate hydration can cause complications
including hypokalemia and cerebral edema. Sodium bicarbonate is not routinely
used in DKA management and is reserved for severe acidosis (pH <6.9). Fingerstick
checks and catheter insertion are important but not priorities. The sequence of
interventions in DKA is: fluids first, then insulin, then electrolyte monitoring.
QUESTION 4
A nurse is assessing a post-operative client 6 hours after abdominal surgery.
The client reports pain of 7/10 and has a respiratory rate of 10 breaths per
minute. Which action should the nurse take?
A) Administer the ordered opioid pain medication
B) Defer pain medication and reassess in 1 hour
, C) Administer only non-opioid pain medication
D) Document findings and continue monitoring
E) Request the physician to change the pain medication order
CORRECT ANSWER: A) Administer the ordered opioid pain medication
RATIONALE: While the respiratory rate of 10 is low-normal (normal is 12-20), the
client is experiencing severe pain (7/10) in the immediate post-operative period.
Uncontrolled post-operative pain delays healing, increases stress response, can
lead to complications like pneumonia and blood clots, and impairs mobility and
recovery. The priority is adequate pain relief. The respiratory rate of 10, while
lower, is still within an acceptable range and does not constitute respiratory
depression that would contraindicate opioid administration. The nurse should
administer the pain medication and continue to monitor respiratory status.
Withholding pain medication would compromise recovery and violate the client's
right to adequate pain management. Post-operative pain management is essential
for optimal healing.
QUESTION 5
A 45-year-old client receiving chemotherapy develops severe nausea and
vomiting. The nurse notes the client has not eaten in 24 hours and is
requesting fluids. Which nursing intervention is MOST appropriate?
A) Offer large amounts of clear liquids
B) Encourage the client to eat small, frequent meals
C) Offer small frequent sips of clear liquids and ice chips
D) Place client on NPO status immediately
E) Administer only intravenous fluids, withhold oral intake
CORRECT ANSWER: C) Offer small frequent sips of clear liquids and ice chips
RATIONALE: In clients experiencing nausea and vomiting secondary to
chemotherapy, small frequent amounts of fluid and ice chips are appropriate to
