ATI RN Comprehensive Predictor 2026 Study Guide
The ATI RN Comprehensive Predictor is the capstone exam most RN programs administer near the end of the nursing curriculum to gauge NCLEX-RN readiness across every core content area — Fundamentals, Medical-Surgical, Pharmacology, Mental Health, Maternal/Newborn, Pediatrics, Leadership, and Community Health. Unlike a single-topic proctored exam, it's built from Next-Generation NCLEX (NGN) style items: case studies, matrix/multiple-response grids, and cloze (drop-down) questions, in addition to standard single-best-answer items.
What This Study Guide Covers
176 original practice questions written in the same NGN style as the real Comprehensive Predictor, organized the way the actual exam blueprint spreads across content areas:
- Fundamentals & Safety — positioning devices, infection control, prioritization/triage.
- Pharmacology — transdermal opioids, anticoagulant monitoring, medication teaching.
- Medical-Surgical — case-study exhibits with vital signs, lab trends, and provider prescriptions.
- Mental Health — personality disorders, psychosis, therapeutic communication.
- Maternal/Newborn & Pediatrics — case studies with dropdown/cloze clinical judgment items.
- Leadership & Community Health — quality improvement, critical pathways, disaster/population-level prioritization.
Every question includes a full rationale for the correct answer and for each incorrect option, so you understand why an answer is right — not just what it is.
How to Do Well on the Comprehensive Predictor
- Get comfortable with NGN item types before test day — case-study exhibits, matrix/multiple-response grids, and dropdown cloze items are scored differently than simple multiple choice.
- Practice prioritization questions (who does the nurse see first?) explicitly; they appear across every content area, not just Leadership.
- Review every missed rationale, including why each wrong option is wrong — the predictor rewards elimination skill as much as recall.
- Don't neglect Community Health and Leadership content — they're smaller sections but still pull down a comprehensive score if skipped.
- Time yourself on case-study clusters; multi-part exhibits take longer than single-stem questions.
Sample Questions & Answers
Try these sample questions in the style of the real Comprehensive Predictor. Full explanations are included so you can see exactly why each answer is correct.
Leadership & Quality Improvement:
1. A charge nurse is concerned about a recent increase in facility-acquired catheter infections. Which of the following actions should the nurse take first?
- A. Identify possible precipitating factors related to the infections.
- B. Meet with providers to discuss measures to decrease the infections.
- C. Schedule nursing staff training for infection control procedures.
- D. Revise the current policy for catheter care.
Answer: A. The first step in addressing a quality or safety concern is to assess the situation and collect data. Identifying contributing factors guides appropriate, evidence-based interventions before staff training, policy changes, or provider meetings.
Mental Health:
2. A nurse is developing an in-service about personality disorders. Which of the following information should the nurse include when discussing borderline personality disorder?
- A. "The client exhibits impulsive behavior."
- B. "The client is overly concerned about minor details."
- C. "The client might act seductively."
- D. "The client is exceptionally clingy to others."
Answer: A. Impulsivity is a hallmark trait of borderline personality disorder — clients may engage in risky behaviors such as substance use, binge eating, or reckless driving, often in response to emotional instability and fear of abandonment. (B describes obsessive-compulsive personality disorder, C describes histrionic personality disorder, and D describes dependent personality disorder.)
Pharmacology:
3. A nurse is providing discharge teaching to a client who has cancer and a prescription for a fentanyl 25 mcg/hr transdermal patch. Which of the following instructions should the nurse include?
- A. "Avoid high-fiber foods while taking this medication."
- B. "Apply the patch to your forearm."
- C. "Avoid hot tubs while wearing the patch."
- D. "Remove the patch for 8 hours every day to reduce the risk of tolerance."
Answer: C. Heat increases the absorption rate of transdermal fentanyl and can lead to overdose, so clients should avoid hot tubs, heating pads, or prolonged sun exposure while wearing the patch. High-fiber foods should be encouraged (not avoided) to counter opioid-induced constipation, and the patch should go on a flat area like the chest, back, or upper arm — not the forearm — and should not be removed intermittently.
Prioritization:
4. A nurse in an emergency department is assessing four clients. Which of the following clients should the nurse see first?
- A. A client who reports a sudden onset of dizziness when sitting up.
- B. A client who has new onset urticaria and angioedema.
- C. A client who has numerous rectal polyps and blood-tinged stools.
- D. A client who has a subluxation of the fifth digit on the left foot.
Answer: B. New urticaria and angioedema suggest a potential anaphylactic reaction, which can quickly progress to airway obstruction — a life-threatening emergency requiring immediate intervention. The other findings need evaluation but don't carry the same immediate airway/circulatory risk.
Pharmacology & Lab Values:
5. A nurse is reporting a client's laboratory tests to the provider to obtain a prescription for the client's daily warfarin. Which of the following laboratory tests should the nurse plan to report?
- A. Fibrinogen level
- B. aPTT
- C. INR
- D. Platelet count
Answer: C. The international normalized ratio (INR) is the standard test used to monitor warfarin therapy — it reflects warfarin's effect on prothrombin time and guides safe, effective dosing. aPTT monitors heparin, not warfarin; fibrinogen and platelet count don't guide warfarin dosing.
Fundamentals & Nutrition:
6. A nurse is caring for a client who has a potassium level of 3.2 mEq/L (3.5 to 5 mEq/L). Which of the following foods should the nurse recommend as being the best source of potassium?
- A. 1/2 cup apple juice
- B. 1/2 cup steamed cauliflower
- C. 1 cup boiled white rice
- D. 1 cup cantaloupe
Answer: D. Cantaloupe is a potassium-rich fruit and the best source of the four options for correcting hypokalemia. Apple juice, cauliflower, and white rice all contain comparatively little potassium.
