QUESTIONS | STEP-BY-STEP FUNDAMENTALS REVIEW FOR EXAM SUCCESS
AND TOP GRADES
Question 1: Which step of the nursing process involves collecting comprehensive data about a
patient's health status?
A. Diagnosis
B. Planning
C. Assessment
D. Implementation
CORRECT ANSWER: C. Assessment
RATIONALE: Assessment is the first and foundational step of the nursing process, during which the
nurse systematically gathers, verifies, and organizes subjective and objective data about the patient's
physical, psychological, sociocultural, and spiritual health to establish a comprehensive baseline for care
planning.
Question 2: When administering medications, which "right" is verified by checking the patient's
identification band against the medication administration record?
A. Right medication
B. Right dose
C. Right patient
D. Right route
CORRECT ANSWER: C. Right patient
RATIONALE: Verifying the right patient is a critical safety step in medication administration. The nurse
confirms the patient's identity using two identifiers (e.g., name and date of birth) by comparing the
medication administration record with the patient's identification band to prevent administration
errors.
Question 3: A nurse observes redness, warmth, and swelling at an intravenous site. Which
complication should the nurse suspect first?
A. Infiltration
B. Phlebitis
C. Air embolism
D. Hematoma
CORRECT ANSWER: B. Phlebitis
,RATIONALE: Phlebitis is inflammation of a vein, commonly indicated by localized redness, warmth,
swelling, and tenderness at or along the IV site. Differentiating phlebitis from infiltration (which presents
with coolness and pallor) guides appropriate intervention, such as discontinuing the IV and applying
warm compresses.
Question 4: Which principle of body mechanics should a nurse prioritize when assisting a patient to
transfer from bed to chair?
A. Keep the feet close together for stability
B. Bend at the waist to lift the patient
C. Maintain a wide base of support
D. Twist the torso while moving the patient
CORRECT ANSWER: C. Maintain a wide base of support
RATIONALE: Maintaining a wide base of support (feet shoulder-width apart) enhances balance and
reduces the risk of musculoskeletal injury to the nurse. Proper body mechanics also include bending at
the knees, keeping the back straight, and avoiding twisting during patient handling.
Question 5: In the chain of infection, which link is broken when a nurse performs hand hygiene before
patient contact?
A. Infectious agent
B. Reservoir
C. Mode of transmission
D. Portal of entry
CORRECT ANSWER: C. Mode of transmission
RATIONALE: Hand hygiene interrupts the mode of transmission, specifically contact transmission, by
removing or destroying pathogens on the nurse's hands before they can be transferred to a susceptible
host. This is a cornerstone of standard precautions and infection control.
Question 6: Which documentation entry best reflects objective data?
A. "Patient appears anxious about surgery."
B. "Patient states, 'I'm scared of the procedure.'"
C. "Patient's hands are trembling; respiratory rate is 24 breaths/min."
D. "Patient seems upset regarding the diagnosis."
CORRECT ANSWER: C. Patient's hands are trembling; respiratory rate is 24 breaths/min.
RATIONALE: Objective data are observable and measurable findings obtained through assessment
techniques (e.g., inspection, palpation, vital signs). Trembling hands and a respiratory rate of 24 are
quantifiable observations, whereas statements about feelings or appearances are subjective
interpretations.
Question 7: A patient with limited English proficiency requires informed consent for a procedure.
What is the nurse's most appropriate action?
,A. Ask a family member to translate the consent form
B. Use a hospital-approved interpreter service
C. Proceed with consent using simple English terms
D. Document that the patient nodded in agreement
CORRECT ANSWER: B. Use a hospital-approved interpreter service
RATIONALE: Professional interpreter services ensure accurate, unbiased communication and uphold
the ethical and legal standards for informed consent. Using family members or untrained staff risks
miscommunication, breaches confidentiality, and may invalidate the consent process.
Question 8: Which finding indicates effective pain management in a postoperative patient?
A. Patient reports pain level of 2/10 and is resting comfortably
B. Patient refuses to ambulate due to fear of pain
C. Patient's blood pressure is elevated at 160/90 mmHg
D. Patient requests analgesics every hour
CORRECT ANSWER: A. Patient reports pain level of 2/10 and is resting comfortably
RATIONALE: Effective pain management is evidenced by the patient's self-report of reduced pain
intensity (using a validated scale) combined with functional improvements, such as the ability to rest,
participate in care, or ambulate. Physiological signs alone are less reliable indicators.
Question 9: When prioritizing patient care using Maslow's hierarchy of needs, which intervention
addresses the most fundamental need?
A. Providing emotional support for anxiety
B. Administering prescribed antibiotics for infection
C. Assisting with activities of daily living for hygiene
D. Ensuring a patent airway and adequate oxygenation
CORRECT ANSWER: D. Ensuring a patent airway and adequate oxygenation
RATIONALE: Maslow's hierarchy prioritizes physiological needs (e.g., airway, breathing, circulation) as
the most fundamental for survival. Airway and oxygenation take precedence over safety,
love/belonging, esteem, or self-actualization needs in clinical prioritization.
Question 10: Which action by the nurse demonstrates therapeutic communication?
A. Offering personal advice based on the nurse's experience
B. Changing the subject when the patient discusses distressing topics
C. Using open-ended questions to explore the patient's concerns
D. Reassuring the patient that "everything will be fine"
CORRECT ANSWER: C. Using open-ended questions to explore the patient's concerns
RATIONALE: Therapeutic communication techniques, such as open-ended questions, encourage
patients to express feelings and concerns, fostering trust and facilitating comprehensive assessment.
, Giving advice, changing subjects, or offering false reassurance are nontherapeutic and can hinder the
nurse-patient relationship.
Question 11: A nurse notes a stage 2 pressure injury on a patient's sacrum. Which characteristic is
expected?
A. Full-thickness skin loss with visible subcutaneous fat
B. Non-blanchable erythema of intact skin
C. Partial-thickness loss of dermis presenting as a shallow ulcer
D. Full-thickness tissue loss with exposed bone or muscle
CORRECT ANSWER: C. Partial-thickness loss of dermis presenting as a shallow ulcer
RATIONALE: Stage 2 pressure injuries involve partial-thickness loss of the dermis, appearing as a
shallow open ulcer with a red-pink wound bed, without slough or bruising. Stage 1 shows intact skin
with non-blanchable redness; stages 3 and 4 involve full-thickness tissue loss.
Question 12: Which laboratory value should the nurse monitor most closely for a patient receiving
warfarin therapy?
A. Complete blood count (CBC)
B. International normalized ratio (INR)
C. Serum potassium level
D. Blood urea nitrogen (BUN)
CORRECT ANSWER: B. International normalized ratio (INR)
RATIONALE: Warfarin is an anticoagulant that prolongs clotting time; the INR standardizes prothrombin
time results to monitor therapeutic effectiveness and bleeding risk. Target INR ranges (typically 2-3 for
most conditions) guide dose adjustments to balance efficacy and safety.
Question 13: When teaching a patient about deep breathing exercises postoperatively, what is the
primary physiological benefit the nurse should emphasize?
A. Enhances digestion and appetite
B. Prevents atelectasis and promotes oxygenation
C. Reduces the need for analgesic medications
D. Accelerates wound healing at the incision site
CORRECT ANSWER: B. Prevents atelectasis and promotes oxygenation
RATIONALE: Deep breathing exercises expand the lungs, mobilize secretions, and prevent alveolar
collapse (atelectasis), a common postoperative complication. Improved ventilation enhances gas
exchange and reduces the risk of pneumonia, supporting respiratory recovery.
Question 14: Which scenario exemplifies a nurse demonstrating advocacy?
A. Completing all documentation before the end of the shift
B. Questioning a medication order that appears unsafe for the patient
