ATI Fundamentals 200 Practice Questions with
Correct Detailed Answers & Well Explained
Rationales – NCLEX Prep, Nursing Exam Study
Guide (2026-2027)
INTRODUCTION:
This comprehensive study guide contains 200 ATI Fundamentals practice questions designed to mirror
the format, difficulty, and content of the ATI RN Fundamentals Proctored Exam and the NCLEX-RN®.
Each question includes a bolded correct answer and an italicized rationale to reinforce clinical
judgment and critical thinking.
Questions 1–50
1. A nurse is preparing to insert an indwelling urinary catheter for a female client. Which action should
the nurse take first?
A) Apply sterile gloves
B) Lubricate the catheter tip
C) Assess the client for latex allergy
D) Open the sterile kit
Rationale: Assessment is the first step of the nursing process. Identifying a latex allergy prevents a life-
threatening reaction.
2. A client receiving continuous enteral feedings via NG tube should be placed in which position to
reduce aspiration risk?
A) Supine
B) Semi-Fowler’s (30–45°)
C) Trendelenburg
D) Left lateral
,Rationale: Semi-Fowler’s uses gravity to prevent gastric reflux. Supine and Trendelenburg increase
aspiration risk.
3. A nurse assesses a peripheral IV site. Which finding indicates phlebitis?
A) Cool, pale skin
B) Redness and warmth along the vein
C) Pitting edema around site
D) Serous drainage at insertion
Rationale: Phlebitis is vein inflammation → redness, warmth, pain. Cool skin suggests infiltration.
4. A client needs a clean-catch midstream urine specimen. Which instruction is correct?
A) “Collect first morning urine.”
B) “Begin urinating, then collect specimen in cup.”
C) “Empty entire bladder into container.”
D) “Wipe back to front before collecting.”
Rationale: Midstream collection avoids contamination. Starting flow flushes urethral meatus.
5. A nurse applies restraints to a confused client pulling at an IV line. Which action is correct?
A) Tie restraints to side rail
B) Ensure two fingers fit between restraint and wrist
C) Remove restraints every 4 hours
D) Apply tightly over clothing
*Rationale: Two-finger width prevents circulatory compromise. Restraints to bed frame (not side rail);
remove every 2 hours.*
6. A client has constipation from oxycodone. Which nonpharmacologic intervention first?
A) Bisacodyl suppository
B) Increase fluids to 2–3 L/day
C) Senna tablet
, D) Tap water enema
Rationale: Opioids slow peristalsis. Fluids, fiber, mobility are first-line. Medications added if
ineffective.
7. A client uses a PCA pump. Which statement shows understanding?
A) “Family can press button if I’m asleep.”
B) “Wait until pain is severe.”
C) “Pump gives continuous dose without me doing anything.”
D) “I can press button when I feel pain, but it won’t give more than the set limit.”
Rationale: PCA has lockout interval to prevent overdose. Only patient presses button.
8. A client has an NG tube to low intermittent suction. Which finding requires immediate action?
A) Gastric output 300 mL/8hr
B) Abdominal distension and nausea
C) Clear yellow drainage
D) Pain at nares
Rationale: Distension + nausea suggests tube obstruction or dislodgment → perforation risk.
9. A nurse applies a transparent film dressing to a pressure injury. Correct order?
A) Apply skin protectant then film
B) Cut film to exact wound size
C) Dry surrounding skin, apply film with 1–2 inch border
D) Place gauze under film
Rationale: Transparent film needs dry, intact periwound skin and overlap onto healthy skin for seal.
10. A client on fall precautions needs the bathroom. What should the nurse do?
A) Place call light and leave
B) Apply wrist restraints
C) Stay with client and assist to bedside commode
, D) Raise all side rails
Rationale: Direct supervision is safest for high fall risk. Bedside commode safer than walking to
bathroom.
11. A client with pneumonia has which vital sign finding requiring immediate action?
A) Temp 38.3°C (100.9°F)
B) SpO2 88% on room air
C) RR 24/min
D) BP 118/72
Rationale: SpO2 <90% indicates hypoxemia. Apply oxygen and notify provider.
12. Home oxygen teaching. Which client statement indicates safety understanding?
A) “Wool blankets are fine.”
B) “Store oxygen tank in closet.”
C) “Avoid petroleum-based products near face.”
D) “Smoke if 10 feet away.”
Rationale: Petroleum products are flammable with oxygen. Store upright, no smoking anywhere.
13. A tuberculin skin test is administered via which route?
A) Subcutaneous
B) Intradermal
C) Intramuscular
D) Topical
Rationale: PPD/Mantoux is intradermal, usually on forearm.
14. A nurse hears a new murmur during auscultation. What should the nurse do first?
A) Document in chart
B) Notify family
C) Assess vital signs and notify provider
