HESI RN FUNDAMENTALS EXIT EXAM
2026–2027 PRACTICE QUESTIONS WITH
VERIFIED ANSWERS & COMPREHENSIVE
RATIONALES NURSING FUNDAMENTALS
& NGN NCLEX REVIEW
This comprehensive question practice block is
meticulously engineered to mirror the exact critical
thinking depth, Next-Generation formatting, and core
clinical domains tested on the HESI RN
Fundamentals Exit Exam. Every high-yield question
features a verified correct answer accompanied by a
comprehensive, bolded rationale designed to rapidly
accelerate concept mastery and maximize test
scores. Ideal for nursing students seeking a rigorous,
systematic review of fluid balance, safety
precautions, medication administration, and priority-
setting frameworks before exam day.
1. A nurse is preparing to administer an intramuscular injection to an
infant. Which muscle site should the nurse select as the safest
, location?
A) Deltoid
B) Dorsogluteal
C) Ventrogluteal
D) Vastus lateralis
Answer: D
Rationale: The vastus lateralis is the largest and most developed
muscle in infants and is free of major nerves and blood vessels,
making it the safest site for intramuscular injections in this
population. The deltoid muscle is not sufficiently developed in infants.
The dorsogluteal site is avoided due to the proximity of the sciatic
nerve. The ventrogluteal site is preferred for adults but is not the
primary site for infants.
2. A client who is on prolonged bed rest is at risk for developing deep
vein thrombosis (DVT). Which nursing intervention is most
effective in preventing this complication?
A) Placing a pillow under the client's knees
B) Massaging the client's lower extremities daily
C) Applying sequential compression devices (SCDs)
D) Limiting fluid intake to decrease blood volume
Answer: C
Rationale: Sequential compression devices (SCDs) promote venous
return by mimicking the muscle pump mechanism, which directly
prevents venous stasis and DVT formation. Placing a pillow under the
knees can compress local blood vessels and increase stasis. Massaging
the legs is contraindicated because it can dislodge an existing,
undetected clot. Fluid intake should be encouraged, not limited, to
,prevent dehydration and hemoconcentration, which increase clotting
risk.
3. A nurse is caring for a client with a localized bacterial infection.
Which laboratory value should the nurse expect to be elevated?
A) Erythrocytes
B) Neutrophils
C) Lymphocytes
D) Basophils
Answer: B
Rationale: Neutrophils are the primary white blood cells responsible
for fighting acute bacterial infections via phagocytosis. Erythrocytes
are red blood cells, which carry oxygen and do not change in response
to infection. Lymphocytes typically elevate during chronic bacterial or
viral infections. Basophils are involved in allergic and inflammatory
responses, not acute localized bacterial infections.
4. An older adult client is admitted to the hospital with acute
confusion and disorientation. Which physiological cause should
the nurse investigate first?
A) Early onset of Alzheimer's disease
B) Urinary tract infection (UTI)
C) Normal age-related cognitive decline
D) Chronic sleep deprivation
Answer: B
Rationale: In older adults, a sudden or acute onset of confusion
(delirium) is a classic, atypical sign of a physical infection, most
commonly a urinary tract infection (UTI). Alzheimer's disease causes a
progressive, gradual decline in cognition, not an acute onset. Normal
, aging does not cause sudden confusion or disorientation. While sleep
deprivation can cause fatigue, it rarely causes sudden, severe
disorientation without a underlying medical trigger.
5. While assessing a client's surgical wound, the nurse notes the
evisceration of a bowel loop. Which action should the nurse take
immediately?
A) Push the bowel loop gently back into the abdominal cavity.
B) Cover the protruding intestine with sterile dressings moistened
with sterile normal saline.
C) Document the findings and reassess the wound in 15 minutes.
D) Place the client in a high-Fowler's position to reduce abdominal
pressure.
Answer: B
Rationale: Evisceration is a medical emergency. Covering the exposed
tissue with sterile dressings soaked in sterile normal saline keeps the
organ moist and minimizes the risk of infection or tissue necrosis. The
nurse must never attempt to reinsert protruding organs. Waiting 15
minutes to document or reassess delays life-saving surgical
intervention. The client should be placed in a low-Fowler's position
with knees bent to minimize abdominal wall tension.
6. A nurse is reviewing oxygen safety precautions with a client who is
being discharged with home oxygen therapy. Which instruction is
crucial to include?
A) Secure the oxygen cylinders in an upright position.
B) Use petroleum jelly to moisturize dry nasal passages.
C) Wear synthetic clothing like nylon or polyester while using
oxygen.
