ATI RN Fundamentals 2026: 70-Question Proctored
Exam Simulation with Detailed Rationales
A complete 70-question practice exam modeled after the ATI RN Fundamentals
2026 blueprint, designed to reinforce core nursing concepts and clinical judgment
through detailed answer rationales.
Question: 1 of 70
A nurse is caring for a client who is postoperative following an appendectomy. The nurse
should first address which of the following findings?
Exhibit 1: Medical History
History of asthma and irritable bowel syndrome.
Exhibit 2: Nurses' Notes
• Day 1: Bilateral breath sounds are clear and present throughout. Client reports they
have been unable to have a bowel movement for the past 3 days. Hypoactive bowel
sounds.
• Day 2: Respirations are shallow. Bilateral breath sounds with scattered wheezing. Client
reports nausea and continued constipation. Abdomen is soft, nondistended with bowel
sounds hypoactive in all four quadrants.

Select...
A. Respiratory status
B. Bowel elimination
C. Nausea
D. Abdominal distension

,ATI RN Fundamentals 2026 Proctored Exam Simulation | Detailed Rationales
Correct Answer:
A. Respiratory status
Detailed Rationale:
Correct Answer: A. Respiratory status
• Clinical Reasoning: When prioritizing client care, the nurse must follow the ABCs
(Airway, Breathing, Circulation) and Maslow’s Hierarchy of Needs (Physiological needs
take priority). On Day 2, the client's respiratory status has significantly deteriorated
(shallow respirations, scattered wheezing). The client has a medical history of asthma,
which places them at high risk for an acute asthma exacerbation or bronchospasm
postoperatively. Respiratory compromise is an immediate life-threatening threat. The
nurse must first assess the airway and breathing, likely administer a prescribed
bronchodilator, and apply oxygen if needed.
• Priority Framework: This falls under "Airway/Breathing," which always takes precedence
over gastrointestinal or comfort issues.
Incorrect Answers and Rationales:
• B. Bowel elimination: While the client is experiencing constipation (no BM for 3 days)
and hypoactive bowel sounds, this is an expected postoperative complication due to
anesthesia and decreased mobility. It does not pose an immediate life threat. Bowel
elimination is a lower priority than respiratory status.
• C. Nausea: The client reports nausea on Day 2. While unpleasant, nausea is a common
postoperative side effect and does not immediately threaten the client's airway or
breathing. It is a lower priority than respiratory distress.
• D. Abdominal distension: The nurse notes that the client's abdomen is soft and
nondistended on Day 2, despite the client's report of constipation. Therefore, abdominal
distension is not currently an active, severe finding requiring immediate intervention
compared to the wheezing and shallow respirations.
Nursing Interventions & Next Steps:
1. Respiratory First: Raise the head of the bed to High-Fowler's or Semi-Fowler's position
to maximize lung expansion. Administer prescribed rescue bronchodilators (e.g.,
Albuterol) via nebulizer or inhaler. Apply supplemental oxygen if SpO2 is below the
prescribed threshold. Encourage the use of an incentive spirometer.

2. Monitor: Continuously monitor oxygen saturation, respiratory rate, and lung sounds.
3. Bowel Management (Secondary): Once the respiratory status is stabilized, the nurse can
address the constipation by encouraging ambulation, increasing fluid intake, and
administering prescribed stool softeners or laxatives as ordered.
Question: 2 of 70
A nurse is caring for a client who has Clostridioides difficile (C. diff) infection and is on contact
precautions. Which of the following actions should the nurse take?
A. Apply a surgical mask before entering the room.
B. Use an alcohol-based hand rub after removing gloves.
C. Wear a gown and gloves when entering the room.
D. Place the client in a negative-pressure airflow room.
Correct Answer: C. Wear a gown and gloves when entering the room.
Detailed Rationale:
• C. Correct: C. diff is transmitted via the fecal-oral route. Contact precautions require the
use of gloves and a gown for any contact with the client or their environment to prevent
the spread of spores.
• A. Incorrect: A surgical mask is required for droplet precautions, not contact
precautions. C. diff does not require airborne or droplet precautions.
• B. Incorrect: Alcohol-based hand rubs are ineffective against C. diff spores. The nurse
must wash hands with soap and water after removing gloves.
• D. Incorrect: A negative-pressure airflow room is required for airborne precautions (e.g.,
tuberculosis, measles).

Question: 3 of 70
A nurse is delegating tasks to an assistive personnel (AP). Which of the following tasks is
appropriate for the nurse to delegate?
A. Assessing a client's surgical incision.
B. Administering a PRN pain medication.
C. Obtaining vital signs on a stable client.
D. Teaching a client how to use an incentive spirometer.
Correct Answer: C. Obtaining vital signs on a stable client.
Detailed Rationale:
• C. Correct: Obtaining vital signs on a stable client is a standard, routine task that falls
within the scope of practice for an AP.
• A. Incorrect: Assessment (including assessing a surgical incision) is the responsibility of
the RN and cannot be delegated.
• B. Incorrect: Medication administration is the responsibility of the RN (or LPN based on
state practice acts) and cannot be delegated to an AP.
• D. Incorrect: Client education is a core nursing responsibility that requires the clinical
judgment of an RN and cannot be delegated to an AP.
Question: 4 of 70
A nurse is preparing to administer digoxin to a client who has heart failure. Which of the
following findings should the nurse identify as a contraindication to administering the
medication?
A. Heart rate 58/min.
B. Potassium 4.2 mEq/L.
C. Blood pressure 110/70 mm Hg.
D. Respiratory rate 18/min.
Correct Answer: A. Heart rate 58/min.
