Expert-Verified Q&A | NCLEX-Ready Format
Introduction
This comprehensive assessment document evaluates nursing competency across
critical clinical scenarios for the 2026/2027 academic cycle. The content is
anchored in the ATI RN Comprehensive curriculum, the Next Generation NCLEX
(NGN) Test Plan, and current evidence-based nursing practice standards across all
major clinical specialties. Each question has been verified against current nursing
literature, ATI module content, and NCLEX-RN test plan objectives. The exam
emphasizes the integration of medical-surgical, maternal-newborn, pediatric,
mental health, and community health nursing concepts, alongside advanced clinical
judgment, leadership, and evidence-based practice required for NCLEX-RN
readiness and program completion. Candidates who complete this actual exam will
demonstrate the clinical judgment, patient safety competence, and evidence-based
knowledge required to deliver expert nursing care across the lifespan in diverse
clinical settings.
1. A 68-year-old client is admitted with acute decompensated heart failure.
Which assessment finding is the priority for the nurse to report to the
provider immediately?
A. Bilateral crackles in the lower lobes with frothy pink sputum
B. Weight gain of 2 pounds over the past 3 days
C. Fatigue when ambulating to the bathroom
D. Mild dyspnea on exertion
Answer: A
Rationale: Frothy pink sputum with bilateral crackles indicates pulmonary edema,
a life-threatening complication of acute decompensated heart failure requiring
immediate intervention with oxygen, IV diuretics (typically furosemide), and
possibly noninvasive positive pressure ventilation. The ABC (Airway-Breathing-
Circulation) framework prioritizes this finding over the others. B (gradual weight
gain) indicates fluid retention but is not immediately life-threatening. C and D
,(fatigue, mild dyspnea on exertion) are expected findings in heart failure and do
not require immediate provider notification.
2. A client receiving IV heparin for a deep vein thrombosis has an aPTT of
110 seconds (control 30-40 seconds). The protocol indicates to administer
protamine sulfate. Which action should the nurse take first?
A. Administer protamine sulfate 50 mg IV push over 10 minutes
B. Stop the heparin infusion immediately
C. Notify the provider and request a different anticoagulant
D. Recheck the aPTT in 2 hours
Answer: B
Rationale: When a client on heparin has a critically prolonged aPTT (greater than
100 seconds), the first nursing action is to stop the heparin infusion to prevent
further anticoagulation and bleeding risk, then administer the antidote (protamine
sulfate) per protocol and notify the provider. Stopping the infusion addresses the
cause immediately. A is correct as a follow-up action but only after the infusion is
stopped. C is incorrect because changing anticoagulants is a provider decision
made after the immediate crisis. D delays intervention in a critically prolonged
value.
3. A client presents to the emergency department with chest pain rated 8/10,
diaphoresis, and shortness of breath. The ECG shows ST-segment elevation in
leads II, III, and aVF. Which interpretation is most accurate?
A. Anterior wall myocardial infarction
B. Inferior wall myocardial infarction
C. Lateral wall myocardial infarction
D. Subendocardial myocardial infarction
Answer: B
Rationale: ST-segment elevation in leads II, III, and aVF indicates an inferior wall
myocardial infarction, caused by occlusion of the right coronary artery (RCA) in
approximately 80% of cases (right-dominant circulation). The nurse should
anticipate emergency percutaneous coronary intervention (PCI) and administer
aspirin, nitroglycerin, morphine, oxygen if hypoxic, and a beta-blocker as ordered.
A (anterior) is seen in V1-V4 (LAD occlusion). C (lateral) is seen in I, aVL, V5-V6
,(circumflex). D (subendocardial) typically shows ST depression or T wave
inversion, not elevation.
4. A client with hypertension is started on lisinopril. Which finding should the
nurse monitor for as a potential serious adverse effect of this medication?
A. Hypokalemia
B. Angioedema of the lips and tongue
C. Tachycardia
D. Hyperglycemia
Answer: B
Rationale: Angioedema is a life-threatening adverse effect of ACE inhibitors like
lisinopril, occurring most commonly in the first 30 days of therapy but possible at
any time. Swelling of the lips, tongue, face, or throat can compromise the airway
and requires immediate discontinuation of the medication, airway management,
and possible administration of epinephrine, antihistamines, and corticosteroids. A
is incorrect because ACE inhibitors cause potassium retention (hyperkalemia), not
hypokalemia. C (tachycardia) is not a typical effect. D (hyperglycemia) is not
associated with ACE inhibitors.
5. A client is receiving digoxin for heart failure. The nurse should hold the
medication and notify the provider when the apical pulse is below which
threshold?
A. 50 bpm
B. 60 bpm
C. 70 bpm
D. 80 bpm
Answer: B
Rationale: Digoxin should be held when the apical heart rate is below 60 bpm in
an adult client, as bradycardia is a sign of digoxin toxicity. The nurse should count
the apical pulse for a full minute before administering the medication and
document the assessment. A (50 bpm) is too low and the medication should already
have been held. C and D (70 and 80 bpm) are within acceptable ranges and do not
require holding.
, 6. A client is 24 hours postoperative following an abdominal aortic aneurysm
repair. Which assessment finding requires immediate provider notification?
A. Urine output of 35 mL/hr
B. Bowel sounds absent in all four quadrants
C. Serum creatinine of 1.8 mg/dL (baseline 1.0 mg/dL)
D. Temperature of 99.4°F (37.4°C)
Answer: C
Rationale: Elevated serum creatinine post-AAA repair suggests renal artery
compromise or contrast-induced nephropathy, which is a surgical emergency
requiring immediate provider notification. AAA repair involves clamping near the
renal arteries, and graft-related or thrombotic complications can compromise
renal perfusion. A (35 mL/hr) is at the lower limit of acceptable but warrants
monitoring. B (absent bowel sounds) is expected in the first 24-48 hours
postoperatively due to ileus. D (low-grade fever) is a normal postoperative
inflammatory response.
7. A client with a history of myocardial infarction is prescribed a beta-
blocker. The nurse understands that the primary therapeutic effect of beta-
blockers in cardiovascular disease is to:
A. Increase cardiac contractility
B. Decrease heart rate, blood pressure, and myocardial oxygen demand
C. Promote diuresis and reduce preload
D. Vasodilate coronary arteries
Answer: B
Rationale: Beta-blockers reduce sympathetic stimulation of the heart, decreasing
heart rate, blood pressure, and myocardial contractility. This reduces myocardial
oxygen demand, making them beneficial in heart failure, post-MI, hypertension,
and angina. They improve survival in clients with reduced ejection fraction heart
failure. A is incorrect because beta-blockers decrease contractility. C describes
diuretics. D describes nitrates.
8. A client is admitted with suspected infective endocarditis. Which
assessment finding is most consistent with this diagnosis?
A. New holosystolic murmur at the apex with splinter hemorrhages and Osler
