NUR 112 HESI EXAM – 300 PRACTICE QUESTIONS
2026/2027 VERIFIED QUESTIONS &
DETAILED RATIONALES (100% VERIFIED ANSWERS)
| ALREADY GRADED A+
DOMAIN 1 – FUNDAMENTALS OF NURSING (Questions 1–60)
1. A nurse is preparing to insert an indwelling urinary catheter. Which
technique is appropriate?
A. Clean glove insertion without drape
B. Sterile gloves, sterile field, sterile catheter
C. Non-sterile gloves with antiseptic solution only
D. Clean technique for home care only
Correct Answer: B
Rationale: Indwelling urinary catheter insertion requires sterile technique
(sterile gloves, field, lubricant, catheter) to prevent catheter-associated
urinary tract infection (CAUTI). Clean technique is insufficient for this
invasive procedure. Using sterile gloves and a sterile field is the standard
of care for urinary catheterization.
2. A patient on fall precautions asks to use the bathroom. What is the
nurse's priority action?
A. Tell the patient to use a bedpan
B. Assist the patient to the bathroom with a gait belt
C. Let the patient go alone
D. Ask family to help
Correct Answer: B
Rationale: Fall precautions require direct assistance. A gait belt and
steadying the patient reduce fall risk. Allowing the patient to go alone
or delegating to untrained family members without supervision is unsafe.
Using a bedpan may be appropriate but does not address the patient's request
and does not maintain dignity.

,3. A nurse sees a small fire in a patient's trash can. What action should
the nurse take first?
A. Pull the fire alarm
B. Evacuate the patient
C. Use the nearest fire extinguisher
D. Run for help
Correct Answer: C
Rationale: RACE: Rescue patients, pull Alarm, Contain fire, Extinguish if
small. Since the fire is small and contained, the nurse should use the
extinguisher first. If the fire cannot be contained, the nurse would then
activate the alarm and evacuate.
4. A nurse is applying wrist restraints to prevent a confused patient from
pulling out an IV. Which action is correct?
A. Tie restraints to the side rail
B. Tie restraints to the bed frame
C. Apply restraints tightly to prevent movement
D. Remove restraints every 4 hours
Correct Answer: B
Rationale: Restraints should be tied to the bed frame, not the side rail,
to prevent injury if the side rail is lowered. Restraints must be removed
and skin checked every 2 hours, not every 4 hours. Restraints should not be
applied tightly; they should allow for two fingers of space.
5. Which task can an RN delegate to an unlicensed assistive personnel (UAP)?
A. Initial admission assessment
B. Ambulation of a stable patient
C. Medication administration
D. Patient teaching about insulin
Correct Answer: B
Rationale: Ambulation of a stable patient is a routine task that can be
delegated to UAP. Initial assessments, medication administration, and
2
,patient teaching require nursing judgment and cannot be delegated.
6. The nurse determines that a postoperative client's respiratory rate has
increased from 18 to 24 breaths/min. Based on this assessment finding,
what is the priority nursing action?
A. Encourage the client to increase ambulation
B. Offer the client a high-carbohydrate snack for energy
C. Force fluids to thin the client's pulmonary secretions
D. Determine if pain is causing the client's tachypnea
Correct Answer: D
Rationale: Pain, anxiety, and increasing fluid accumulation in the lungs
can cause tachypnea. Determining if pain is causing the increased
respiratory rate is the priority to address the underlying cause.
Encouraging ambulation when the respiratory rate is rising above normal
limits puts the client at risk for further oxygen desaturation.
High-carbohydrate snacks can increase carbon metabolism, and forcing
fluids could increase respiratory congestion.
7. Urinary catheterization is prescribed for a postoperative female client
who has been unable to void for 8 hours. The nurse inserts the catheter,
but no urine is seen in the tubing. Which action will the nurse take next?
A. Clamp the catheter and recheck it in 60 minutes
B. Pull the catheter back 3 inches and redirect upward
C. Leave the catheter in place and reattempt with another catheter
D. Notify the healthcare provider of a possible obstruction
Correct Answer: C
Rationale: It is likely that the first catheter is in the vagina rather
than the bladder. Leaving the first catheter in place will help locate the
meatus when attempting the second catheterization. The client should have
at least 240 mL of urine after 8 hours. There is no evidence of a urinary
tract obstruction if the catheter could be easily inserted.
8. Which serum laboratory value should the nurse monitor carefully for a
client who has a nasogastric (NG) tube to suction for the past week?
3
, A. White blood cell count
B. Albumin
C. Calcium
D. Sodium
Correct Answer: D
Rationale: Monitoring serum sodium levels for hyponatremia is indicated
during prolonged NG suctioning because of loss of fluids rich in
electrolytes. Changes in white blood cell count, albumin, or calcium are
not typically associated with prolonged NG suctioning.
9. A nurse is teaching a client proper use of an inhaler. When should the
client administer the inhaler-delivered medication to demonstrate
correct use?
A. Immediately after exhalation
B. During the inhalation
C. At the end of three inhalations
D. Immediately after inhalation
Correct Answer: B
Rationale: The client should be instructed to deliver the medication during
the last part of inhalation. After the medication is delivered, the client
should remove the mouthpiece, keep lips closed, and hold breath for several
seconds to allow for distribution of the medication. The client should
deliver no more than two inhalations at a time.
10. A male client being discharged with a prescription for the bronchodilator
theophylline tells the nurse that he understands he is to take three
doses of the medication each day. Since timed-release capsules are not
available, which dosing schedule should the nurse advise?
A. 9 a.m., 1 p.m., and 5 p.m.
B. 8 a.m., 4 p.m., and midnight
C. Before breakfast, before lunch, and before dinner
D. With breakfast, with lunch, and with dinner
Correct Answer: B
