NURS 101: ATI RN Fundamentals Prep with
Detailed Rationales
Course Code: NURS 101
Course Name: ATI RN Fundamentals
Topic: Comprehensive Fundamentals Practice Exam Pack
Academic Year: 2026/2027
1. A nurse is caring for a client who is post-operative and reporting severe
pain. The nurse administers morphine sulfate intravenously. Which of the
following adverse effects represents the highest clinical priority for
immediate assessment?
A. Respiratory depression
B. Constipation
C. Urinary retention
D. Pruritus
CORRECT ANSWER: A
RATIONALE: According to Maslow's Hierarchy of Needs and the ABC
(Airway, Breathing, Circulation) framework, respiratory depression is a life-
threatening adverse effect of opioid analgesics like morphine sulfate and must be
prioritized first. Constipation, urinary retention, and pruritus are known side effects
but do not pose an immediate threat to life.
2. A nurse is preparing to administer an intramuscular injection to an obese
adult client. Which of the following sites is the most appropriate to ensure
deep intramuscular deposition of the medication?
A. Dorsogluteal site
B. Ventralgluteal site
C. Deltoid site
D. Vastus lateralis site
CORRECT ANSWER: B
RATIONALE: The ventrogluteal site is the preferred and safest site for deep
intramuscular injections in adults because it contains a thick muscle layer, is free
of major nerves and blood vessels, and has less adipose tissue compared to other
,sites, ensuring medication reaches the muscle layer even in obese clients. The
dorsogluteal site is no longer recommended due to proximity to the sciatic nerve.
3. A nurse is caring for a client who has a prescription for airborne
precautions. Which of the following personal protective equipment (PPE) is
mandatory prior to entering the client's room?
A. Surgical mask
B. Gown and gloves
C. N95 respirator
D. Face shield
CORRECT ANSWER: C
RATIONALE: Airborne precautions require the use of a fitted N95 or higher-
level respirator to filter small airborne droplets (e.g., tuberculosis, varicella,
measles). Surgical masks are used for droplet precautions, not airborne. Gowns and
gloves are standard or contact precautions depending on the scenario.
4. A nurse is reviewing laboratory results for a client and notes a serum
potassium level of 2.8 mEq/L. Which of the following clinical
manifestations should the nurse monitor for most closely?
A. Severe diarrhea
B. Cardiac arrhythmias
C. Hyperreflexia
D. Positive Trousseau's sign
CORRECT ANSWER: B
RATIONALE: Hypokalemia (potassium level below 3.5 mEq/L) profoundly
affects myocardial electrical conduction, leading to dangerous cardiac arrhythmias,
flattened T waves, and ST depression. Hyperreflexia and Trousseau's sign are
associated with hypocalcemia or hypomagnesemia.
5. A nurse is assisting a client during the initiation of a blood transfusion. For
how many minutes must the nurse remain with the client to monitor for an
acute hemolytic reaction?
A. First 15 minutes
B. First 30 minutes
C. Entire first hour
D. First 5 minutes
, CORRECT ANSWER: A
RATIONALE: The first 15 minutes are the most critical because severe, life-
threatening acute hemolytic or anaphylactic transfusion reactions typically
manifest during the administration of the first 50 mL of blood. The nurse must
monitor vital signs frequently during this window.
6. A nurse is reviewing safety protocols regarding restraints. Which of the
following actions must the nurse include in the plan of care for a client who
requires mechanical wrist restraints?
A. Secure the restraint ties to the side rails of the bed.
B. Renew the restraint prescription every 4 hours for an adult.
C. Assess the client's skin and circulation status every 4 hours.
D. Keep the prescription open-ended for PRN usage.
CORRECT ANSWER: B
RATIONALE: Behavioral health or medical-surgical restraint prescriptions for
adults must be renewed every 4 hours up to a total of 24 hours. Restraints must
never be tied to side rails (only to the stable bed frame), skin checks must occur
every 15 to 30 minutes or at minimum every 2 hours, and PRN restraint
prescriptions are strictly prohibited.
7. A nurse is preparing to insert an indwelling urinary catheter for a female
client. Which of the following actions should the nurse perform first?
A. Lubricate the catheter tip.
B. Verify the client's identity using two unique identifiers.
C. Cleanse the labia minora with antiseptic swabs.
D. Open the sterile catheterization kit using aseptic technique.
CORRECT ANSWER: B
RATIONALE: In accordance with National Patient Safety Goals, verifying the
client's identity using two unique identifiers (e.g., full name and date of birth) must
always be performed before any procedure or medication administration to ensure
patient safety. The other steps are correct procedural components but must follow
proper client identification.
8. A nurse is teaching a newly licensed nurse about legal documentation
standards. Which of the following entries demonstrates correct
documentation technique?
A. "Client is manipulation and demanding attention."
, B. "Client states, 'I feel like my heart is racing.' Pulse rate is 112 bpm."
C. "Administered pain medication because the client is a whiner."
D. "Dr. Smith forgot to write the prescription, so I gave the drug anyway."
CORRECT ANSWER: B
RATIONALE: Documentation must be objective, factual, precise, and accurate.
Quoting the client directly and providing objective vital signs avoids subjective
bias or labeling. Options A, C, and D contain highly subjective language and legal
vulnerabilities.
9. A nurse is caring for an older adult client who is at high risk for pressure
injury development. Which of the following interventions should the nurse
implement?
A. Massage bony prominences twice daily.
B. Keep the head of the bed elevated at 45 degrees at all times.
C. Turn and reposition the client at least every 2 hours.
D. Use a donut-shaped cushion when the client sits in a chair.
CORRECT ANSWER: C
RATIONALE: Turning and repositioning a client at least every 2 hours is the
standard evidence-based nursing intervention to relieve mechanical pressure and
prevent tissue ischemia. Massaging bony prominences can cause deep tissue
damage, keeping the head of bed at 45 degrees increases shearing forces, and donut
cushions concentrate pressure around the surrounding tissues.
10.A nurse is calculating a client's fluid intake over an 8-hour shift. The client
consumed: 4 oz of apple juice, 6 oz of broth, 8 oz of gelatin, and 500 mL of
intravenous fluids. How many mL should the nurse document as the total
intake?
A. 518 mL
B. 720 mL
C. 1040 mL
D. 1240 mL
CORRECT ANSWER: C
RATIONALE: To convert ounces to milliliters, multiply by 30 (1 oz = 30 mL).
4 oz juice = 120 mL; 6 oz broth = 180 mL; 8 oz gelatin = 240 mL. Total oral intake
= 120 + 180 + 240 = 540 mL. Total overall intake = 540 mL oral + 500 mL IV =
1040 mL.
