ATI NGN Clinical Judgment Cases 2026–2027
Complete Study Guide with Next Generation NCLEX
Case Studies, Rationales, and Exam Review
Introduction
This comprehensive study guide contains 90, exam-style questions designed
to prepare nursing students for the ATI NGN Clinical Judgment Cases and the
Next Generation NCLEX (NGN) for the 2026–2027 academic year. All
questions are aligned with the NCSBN Clinical Judgment Measurement Model
(NCJMM), ATI Nursing Content Mastery Series standards, and current
evidence-based practice guidelines.
Question 1
A nurse is caring for a 72-year-old client admitted with confusion and fever.
The client's family reports the client has been increasingly confused over the
past 2 days. Which of the following assessment findings should the nurse
identify as the priority cue?
A) Temperature of 101.2°F (38.4°C)
B) Sudden onset of confusion with fever
C) Blood pressure 140/88 mmHg
D) Heart rate 96/min
Answer: B) Sudden onset of confusion with fever
Rationale: Sudden onset of confusion with fever in an older adult is a critical
cue that may indicate sepsis, urinary tract infection, or meningitis. This
pattern of cues requires immediate investigation. While fever (A) is
significant, the combination with confusion (B) represents the most urgent
clinical picture. Blood pressure (C) and heart rate (D) are elevated but not as
concerning as the neurological change with fever.
,Question 2
A nurse is reviewing the electronic health record for a client admitted with
chest pain. Which of the following laboratory values should the nurse identify
as a priority cue?
A) Hemoglobin 12.5 g/dL
B) Troponin I 2.5 ng/mL
C) Serum sodium 138 mEq/L
D) Potassium 4.0 mEq/L
Answer: B) Troponin I 2.5 ng/mL
Rationale: Troponin I is a cardiac biomarker that is elevated in myocardial
injury. A value of 2.5 ng/mL (normal <0.04 ng/mL) is significantly elevated
and indicates acute myocardial infarction. This is the priority cue requiring
immediate follow-up. Hemoglobin (A), sodium (C), and potassium (D) are
within normal limits.
Question 3
A nurse is assessing a client who is 6 hours post-operative following
abdominal surgery. Which of the following assessment findings should the
nurse recognize as the priority cue?
A) Sudden onset of shortness of breath and chest pain
B) Pain rated 6/10 at the surgical site
C) Temperature 99.8°F (37.7°C)
D) Serosanguineous drainage on the dressing
Answer: A) Sudden onset of shortness of breath and chest pain
Rationale: Sudden onset of shortness of breath and chest pain in a post-
operative client is a critical cue for pulmonary embolism (PE), a life-
threatening complication requiring immediate assessment and intervention.
Pain 6/10 (B) is significant but not immediately life-threatening. Low-grade
fever (C) may indicate inflammation or infection but is less urgent.
Serosanguineous drainage (D) is expected post-operatively.
,Question 4
A nurse is caring for a client with diabetic ketoacidosis (DKA). Which of the
following assessment findings should the nurse identify as a priority cue?
A) Polyuria and polydipsia
B) Kussmaul respirations
C) Fruity odor to breath
D) Blood glucose 350 mg/dL
Answer: B) Kussmaul respirations
Rationale: Kussmaul respirations (deep, rapid breathing) are a compensatory
response to metabolic acidosis in DKA and indicate the body is attempting to
blow off carbon dioxide to correct acidosis. This is a critical cue of worsening
acidosis and impending respiratory compromise. Polyuria/polydipsia (A) and
fruity breath (C) are classic signs of DKA but are not as urgent as respiratory
compensation. Hyperglycemia (D) is expected in DKA.
Question 5
A nurse is performing a focused assessment on a client who reports severe
headache, blurred vision, and nausea. The client's blood pressure is 198/112
mmHg. Which of the following is the priority cue?
A) Blood pressure 198/112 mmHg
B) Severe headache
C) Blurred vision
D) Nausea
Answer: A) Blood pressure 198/112 mmHg
Rationale: A blood pressure of 198/112 mmHg indicates hypertensive crisis,
which requires immediate intervention to prevent end-organ damage.
Headache (B), blurred vision (C), and nausea (D) are manifestations of severe
hypertension but are secondary to the elevated blood pressure. The nurse
should place the client in a position of comfort, notify the provider, and
prepare for antihypertensive therapy.
, Question 6
A nurse is reviewing a client's medication administration record and notes a
prescription for furosemide 40 mg IV push. Which of the following cues
should the nurse identify before administering this medication?
A) Heart rate 72/min
B) Serum potassium 3.1 mEq/L
C) Blood pressure 138/82 mmHg
D) Respiratory rate 18/min
Answer: B) Serum potassium 3.1 mEq/L
Rationale: Furosemide is a loop diuretic that causes potassium loss. A serum
potassium of 3.1 mEq/L (normal: 3.5–5.0 mEq/L) indicates hypokalemia,
which is a critical cue requiring correction before administering the
medication due to the risk of arrhythmias. Heart rate (A), blood pressure (C),
and respiratory rate (D) are within normal limits and do not present a priority
concern.
Question 7
A nurse is assessing a client who is 24 hours post-operative following a bowel
resection. The nurse notes that the client's nasogastric (NG) tube drainage has
decreased significantly over the past 2 hours. Which of the following is the
priority action?
A) Notify the provider of the decreased output
B) Continue to monitor the output
C) Irrigate the NG tube with normal saline
D) Increase the suction setting
Answer: A) Notify the provider of the decreased output
Rationale: A sudden decrease in NG tube output after bowel surgery is a
critical cue that may indicate obstruction, displacement, or paralytic ileus. The
provider should be notified immediately for further evaluation. Continuing to
monitor (B) without intervention could delay care. Irrigation (C) and
increasing suction (D) may be harmful without provider guidance.
