This comprehensive study guide is designed to prepare nursing students for the ATI Fundamentals examination by covering essential subject areas
foundational to safe and effective nursing practice. The purpose of this exam is to assess mastery of core nursing fundamentals before progressing
to clinical practice. Students will evaluate their knowledge of the nursing process, patient safety protocols, infection prevention, medication
administration, vital sign measurement, elimination care, nutrition, oxygenation, pain management, and professional standards including ethics,
legal compliance, and documentation. The assessment uses multiple-choice and scenario-based questions that emphasize real-world application,
clinical decision-making, and critical thinking in diverse patient care situations. Success requires both theoretical understanding and the ability to
apply knowledge to practical clinical scenarios.
,SECTION ONE: PRACTICE QUESTIONS (Q1–100)
Question 1
A nurse is preparing to assess a patient's vital signs. Which of the following should be assessed first?
A. Blood pressure
B. Pulse
C. Respiration
D. Temperature
🟢 Correct answer: D
🔴 RATIONALE: Temperature should be assessed first because it is the least invasive and does not alter the patient's state before measuring other
vital signs. Assessing blood pressure, pulse, or respiration first may cause patient anxiety that could affect temperature accuracy.
Question 2
Which of the following is the most appropriate action when a nurse discovers a patient's IV site is red, warm, and swollen?
A. Elevate the limb and continue the infusion
B. Discontinue the IV and apply a warm compress
C. Slow the infusion rate and monitor closely
D. Administer an analgesic through the IV
🟢 Correct answer: B
🔴 RATIONALE: Redness, warmth, and swelling indicate phlebitis or infiltration. The IV must be discontinued immediately to prevent further tissue
damage, and a warm compress promotes circulation and reduces inflammation. Continuing or slowing the infusion worsens the condition.
Question 3
A patient is experiencing severe pain (8/10) 30 minutes after receiving prescribed analgesia. What should the nurse do first?
,A. Administer an additional dose immediately
B. Assess the pain characteristics and location
C. Call the healthcare provider for a new order
D. Document the pain as unresolved
🟢 Correct answer: B
🔴 RATIONALE: The nurse must first assess pain characteristics, location, and contributing factors to determine why the pain persists. This follows
the nursing process (assessment before intervention). Administering additional medication without assessment could be unsafe.
Question 4
Which hand hygiene technique is most appropriate when hands are not visibly soiled?
A. Washing with soap and water for 30 seconds
B. Using an alcohol-based hand rub for 15–30 seconds
C. Wiping with an antiseptic wipe once
D. Washing with soap and water for 5 minutes
🟢 Correct answer: B
🔴 RATIONALE: Alcohol-based hand rubs are effective when hands are not visibly soiled and require 15–30 seconds of application. Soap and water
washing is preferred when hands are visibly dirty or after caring for patients with certain infections (e.g., C. diff).
Question 5
A nurse is teaching a patient about fall prevention. Which intervention is most effective?
A. Keeping the bed in the highest position
B. Placing the call light within reach
C. Locking the wheels only when the nurse is present
D. Raising all four side rails
, 🟢 Correct answer: B
🔴 RATIONALE: Keeping the call light within reach allows patients to request assistance before attempting to move independently, significantly
reducing fall risk. Highest bed position increases fall severity; unlocked wheels and four side rails increase injury risk.
Question 6
Which of the following represents the correct sequence for performing a sterile dressing change?
A. Open sterile supplies → Remove old dressing → Clean wound → Apply new dressing
B. Remove old dressing → Open sterile supplies → Clean wound → Apply new dressing
C. Open sterile supplies → Clean wound → Remove old dressing → Apply new dressing
D. Remove old dressing → Clean wound → Open sterile supplies → Apply new dressing
🟢 Correct answer: A
🔴 RATIONALE: Sterile supplies must be opened before removing the old dressing to maintain the sterile field. Cleaning the wound before removing
the old dressing is impossible, and opening supplies after removing the dressing breaks sterile technique.
Question 7
A patient with a urinary catheter develops cloudy urine with sediment. What is the nurse's priority action?
A. Increase fluid intake and monitor
B. Obtain a urine specimen for culture
C. Clamp the catheter for 2 hours
D. Irrigate the catheter immediately
🟢 Correct answer: B
🔴 RATIONALE: Cloudy urine with sediment suggests possible infection (UTI). Obtaining a urine culture confirms the diagnosis and guides
antibiotic treatment. Increasing fluids may help but doesn't address the infection; clamping or irrigating without orders is unsafe.
