ATI Fundamentals of Nursing Exam Practice Questions
and Answers 2026/2027 – Verified Q&As with Detailed
Rationales (Test Bank Bundle - 83 Questions)

**QUESTION 1:**
A nurse is preparing to administer an intramuscular injection to an adult. Which site is preferred for
volumes of 2 mL?
A) Deltoid
B) Vastus lateralis
C) Ventrogluteal
D) Dorsogluteal
> 🎯 **CORRECT ANSWER:** C) Ventrogluteal
> 💡 **DETAILED RATIONALE:** The ventrogluteal site is the preferred and safest intramuscular
injection site for adults because it is free of major blood vessels and nerves, can accommodate larger
volumes up to 3 mL, and has a thick muscle mass. The deltoid is for small volumes (≤1 mL), the vastus
lateralis is used for infants and children primarily, and the dorsogluteal site risks sciatic nerve injury and
is no longer recommended as a first-choice site.

**QUESTION 2:**
A client's oral temperature is 101.4°F (38.6°C) at 0800. The nurse administers antipyretic medication.
When should the nurse re-evaluate the temperature?
A) 15 minutes after administration
B) 30 to 60 minutes after administration
C) 2 hours after administration
D) At the next scheduled vital signs check
> 🎯 **CORRECT ANSWER:** B) 30 to 60 minutes after administration
> 💡 **DETAILED RATIONALE:** Antipyretic medications such as acetaminophen or ibuprofen typically
begin to reduce fever within 30 to 60 minutes after oral administration, so reassessment at that time
,evaluates the effectiveness of the intervention. Fifteen minutes is insufficient for therapeutic effect,
waiting two hours delays critical evaluation of whether the fever is responding, and waiting for the next
scheduled check may miss an ineffective dose.

**QUESTION 3:**
A nurse is performing a sterile dressing change. The nurse opens a sterile package and a corner of the
package touches clothing. What should the nurse do?
A) Continue because the inner surface is still sterile
B) Discard the package and obtain new sterile supplies
C) Use the package but avoid the touched corner
D) Wipe the touched corner with alcohol and proceed
> 🎯 **CORRECT ANSWER:** B) Discard the package and obtain new sterile supplies
> 💡 **DETAILED RATIONALE:** Once a sterile package touches a non-sterile surface such as clothing,
the entire package is considered contaminated because the barrier has been breached, and sterility
cannot be guaranteed for any portion of the contents. Continuing, avoiding the corner, or attempting to
disinfect a contaminated package violates principles of surgical asepsis and places the client at risk for
infection.

**QUESTION 4:**
A client has a nasogastric tube connected to low intermittent suction. Which finding indicates the tube is
functioning properly?
A) No drainage in the collection canister
B) Greenish-yellow drainage in the canister
C) Client reports a sore throat
D) Absence of bowel sounds
> 🎯 **CORRECT ANSWER:** B) Greenish-yellow drainage in the canister
> 💡 **DETAILED RATIONALE:** Greenish-yellow drainage is gastric contents, indicating the NG tube is
properly positioned in the stomach and the suction is effectively removing stomach contents. No
drainage could indicate a clogged or malpositioned tube, sore throat is an expected discomfort but not
an indicator of function, and absent bowel sounds may indicate an ileus but do not confirm NG tube
function.

**QUESTION 5:**
A nurse is assessing a client for fluid volume deficit. Which finding is expected?
A) Jugular vein distention
B) Crackles in the lungs
C) Orthostatic hypotension
D) Bounding peripheral pulses
> 🎯 **CORRECT ANSWER:** C) Orthostatic hypotension
> 💡 **DETAILED RATIONALE:** Orthostatic hypotension, defined as a drop in systolic blood pressure of
20 mmHg or more when moving from lying to standing, is a classic sign of fluid volume deficit due to
reduced circulating blood volume and compensatory mechanisms being overwhelmed. Jugular vein
distention, crackles, and bounding pulses are signs of fluid volume excess, not deficit.

**QUESTION 6:**
A client is on strict intake and output measurement. Which fluid should the nurse count as intake?
A) Urine output
B) Emesis
C) Intravenous fluids
D) Wound drainage
> 🎯 **CORRECT ANSWER:** C) Intravenous fluids
> 💡 **DETAILED RATIONALE:** Intake includes all fluids entering the body: intravenous fluids, oral
liquids, enteral feedings, ice chips (at half volume), and fluids used to irrigate tubes that are retained.
Urine, emesis, and wound drainage are all outputs measured to calculate fluid balance.

**QUESTION 7:**
A nurse is assessing a client's wound and notes purulent drainage with a foul odor. How should the
nurse document this drainage?
A) Serous
, B) Sanguineous
C) Serosanguineous
D) Purulent
> 🎯 **CORRECT ANSWER:** D) Purulent
> 💡 **DETAILED RATIONALE:** Purulent drainage is thick, often malodorous, and yellow, green, or
brown in color, indicating the presence of white blood cells, bacteria, and cellular debris characteristic of
wound infection. Serous drainage is clear and watery, sanguineous is bloody, and serosanguineous is
pink-tinged thin drainage from a mix of serous and bloody fluid.

**QUESTION 8:**
Which client should the nurse see first after receiving morning shift report?
A) A client with pneumonia scheduled for discharge
B) A client 2 days post-operative with a temperature of 99.8°F
C) A client with chest pain rating pain as 8 out of 10
D) A client requesting assistance with ambulation
> 🎯 **CORRECT ANSWER:** C) A client with chest pain rating pain as 8 out of 10
> 💡 **DETAILED RATIONALE:** Acute chest pain with high severity requires immediate assessment to
rule out life-threatening conditions such as myocardial infarction, which takes priority over discharge
teaching, low-grade fever assessment, and ambulation assistance according to Maslow's hierarchy and
ABC prioritization. Pain at this level signals active physiological distress requiring urgent intervention.

**QUESTION 9:**
The nurse is preparing to administer a subcutaneous injection of heparin. Which technique is correct?
A) Massage the site after injection
B) Aspirate before injecting
C) Inject at a 90-degree angle
D) Inject at a 45- to 90-degree angle without aspiration
> 🎯 **CORRECT ANSWER:** D) Inject at a 45- to 90-degree angle without aspiration
