INTRODUCTION
This comprehensive practice examination is designed for nursing students
preparing for the HESI Fundamentals exam. It evaluates foundational
nursing knowledge including safety, infection control, vital signs, medication
administration, patient positioning, documentation, and ethical/legal
concepts. Each question is followed by a deeply elaborated rationale that
explains not only why the correct answer is right but also why the other
options are incorrect. This approach reinforces clinical judgment and
prepares candidates for the rigor of the HESI examination and real-world
nursing practice.
SECTION ONE: MANAGEMENT OF CARE AND PRIORITIZATION
(QUESTIONS 1–10)
1. A nurse is caring for four clients. Which client should the nurse
assess first?
A. A client with COPD who has an oxygen saturation of 92% on 2L nasal
cannula
B. A client with heart failure who reports increased shortness of breath and
has new crackles
C. A client with diabetes who has a blood glucose of 180 mg/dL
,D. A client recovering from a total knee replacement who is requesting pain
medication
B. A client with heart failure who reports increased shortness of breath
and has new crackles
RATIONALE: This question tests the ABCDE prioritization framework
(Airway, Breathing, Circulation, Disability, Exposure). The client with heart
failure who reports increased shortness of breath and has new crackles is
demonstrating signs of acute pulmonary edema, a life-threatening
complication that directly compromises the airway and breathing. New-
onset crackles indicate fluid is accumulating in the alveoli, impairing gas
exchange. This client requires immediate assessment and intervention. In
contrast, the COPD client with an SpO2 of 92% is stable at their baseline. A
blood glucose of 180 mg/dL is elevated but not immediately dangerous
(hyperglycemia typically becomes emergent above 400-600 mg/dL). Post-
operative pain, while important, is not life-threatening and can be
addressed after the more critical client .
2. A nurse is delegating tasks to an unlicensed assistive personnel
(UAP). Which task is appropriate to delegate?
A. Administering a subcutaneous insulin injection
B. Obtaining a blood pressure reading on a stable client
C. Assessing a client's surgical incision for signs of infection
D. Teaching a client about a new medication
B. Obtaining a blood pressure reading on a stable client
RATIONALE: Delegation requires understanding the five rights of
delegation: right task, right circumstance, right person, right
direction/communication, and right supervision/evaluation. Obtaining vital
signs on a stable client is within the scope of practice for a UAP because it
is a routine, non-invasive task that does not require clinical judgment. The
nurse retains accountability for ensuring the task is appropriate for the
client's condition. Medication administration (A) requires an RN or LPN
license and cannot be delegated to a UAP. Assessment (C) is an RN-level
responsibility that requires clinical judgment and interpretation. Teaching
, (D) is also an RN responsibility because it requires assessing learning
needs and evaluating understanding .
3. A nurse is triaging clients following a mass casualty event. Which
client should be categorized as red (immediate)?
A. A client with a simple fracture of the radius who is ambulatory
B. A client with an open pneumothorax and respiratory distress
C. A client with a minor laceration requiring sutures
D. A client with a contusion who is able to follow commands
B. A client with an open pneumothorax and respiratory distress
RATIONALE: Disaster triage uses a color-coded system: Red
(immediate) for life-threatening conditions requiring intervention within
minutes; Yellow (delayed) for serious but stable conditions; Green (minor)
for ambulatory clients with minor injuries; Black (expectant) for clients who
are deceased or have injuries incompatible with life. An open
pneumothorax with respiratory distress is a life-threatening emergency
requiring immediate chest decompression. Without intervention, this client
will rapidly decompensate. The client with a simple fracture (A) and the
client with a minor laceration (C) are green tags—they are ambulatory and
can wait. The client with a contusion who follows commands (D) is stable
and can be classified as yellow or green depending on severity .
4. A nurse is caring for a client who refuses a prescribed blood
transfusion. The client is competent and has been informed of the
risks. Which action should the nurse take?
A. Administer the transfusion despite the client's refusal
B. Respect the client's right to refuse and document the refusal
C. Ask the family to convince the client to accept the transfusion
D. Notify the provider and request a court order
B. Respect the client's right to refuse and document the refusal
RATIONALE: This question tests the ethical principle of autonomy—the
right of a competent client to make their own healthcare decisions. A
competent client has the legal and ethical right to refuse any treatment,
