50 Questions Verified Answers 4 Core Topics A+ Grade
This guide contains 50 high-yield HESI Fundamentals of Nursing Exit Exam questions with verified answers and detailed
rationales, covering the four most heavily tested fundamentals content areas: vital signs assessment, patient safety, infection
control, and the nursing process (ADPIE). Each question mirrors the NCLEX-style format used on the HESI Fundamentals Exit
Exam, with priority-based reasoning and safety alerts highlighted throughout.
, SECTION 1: VITAL SIGNS (Q1-Q13)
HESI TIP: Pain is the "5th vital sign." Always assess vital signs in context — trends matter more than single readings.
Q1. A nurse is assessing an adult patient's vital signs. Which finding requires IMMEDIATE notification of
the provider?
A. Temperature 99.1°F (37.3°C)
B. Heart rate 124 beats/min, new onset
C. Respiratory rate 18 breaths/min
D. Blood pressure 124/78 mmHg
ANSWER: B. Heart rate 124 beats/min, new onset
Rationale: A new-onset heart rate of 124 bpm (normal: 60-100 bpm) represents significant tachycardia and requires
immediate assessment for underlying causes (pain, fever, hypovolemia, dysrhythmia, anxiety). The other values are within
or near normal limits and do not require urgent notification.
New, unexplained vital sign changes always take priority over chronic or expected findings.
Q2. Which technique provides the MOST accurate body temperature measurement in a critically ill patient?
A. Oral thermometer
B. Tympanic thermometer
C. Pulmonary artery catheter (core) or rectal
D. Axillary thermometer
ANSWER: C. Pulmonary artery catheter (core) or rectal
Rationale: Core temperature methods (pulmonary artery catheter, esophageal probe, or rectal) provide the most accurate
reflection of true body temperature, especially in critically ill or hemodynamically unstable patients. Oral, tympanic, and
axillary methods are convenient but less accurate and more easily affected by external factors.
Q3. A nurse is counting a patient's respiratory rate. Which method ensures the MOST accurate count?
A. Tell the patient you are counting respirations
B. Count while appearing to take the pulse, without informing the patient
C. Ask the patient to breathe normally and count out loud
D. Count for 15 seconds and multiply by 4
ANSWER: B. Count while appearing to take the pulse, without informing the patient
Rationale: Patients often unconsciously alter their breathing pattern when they know it is being observed. Counting
respirations discreetly while appearing to assess the pulse yields a more natural, accurate respiratory rate. Respirations
should be counted for a full 30-60 seconds, especially if irregular.
Q4. A patient's blood pressure reading is 90/50 mmHg. Which assessment finding would be MOST
concerning in combination with this reading?
A. Heart rate 78 bpm, regular
B. Dizziness and pallor when standing
C. Patient reports feeling "fine"
D. Capillary refill <2 seconds
ANSWER: B. Dizziness and pallor when standing
Rationale: A blood pressure of 90/50 combined with symptomatic findings (dizziness, pallor) suggests the patient is not
adequately compensating for low blood pressure — indicating possible orthostatic hypotension or hemodynamic instability
requiring intervention. An asymptomatic low BP in a patient who otherwise has normal perfusion findings is less urgent.
, Always correlate vital sign numbers with the patient's symptoms and overall clinical picture.
Q5. Which pulse site is used to assess for a pulse deficit by comparing simultaneously with the apical
pulse?
A. Carotid pulse
B. Radial pulse
C. Femoral pulse
D. Popliteal pulse
ANSWER: B. Radial pulse
Rationale: A pulse deficit is assessed by having two examiners simultaneously count the apical pulse (at the heart, using a
stethoscope) and the radial pulse (at the wrist). A difference between the two counts (apical > radial) indicates a pulse
deficit, often seen in atrial fibrillation, where not every contraction generates a palpable peripheral pulse.
Q6. A nurse obtains an oxygen saturation reading of 91% via pulse oximetry. The patient has cold,
cyanotic fingers and is wearing dark nail polish. What is the nurse's BEST initial action?
A. Document the reading and continue monitoring
B. Administer supplemental oxygen immediately
C. Reposition the probe to a warmer site, such as the earlobe, and remove nail polish if possible
D. Notify the provider immediately
ANSWER: C. Reposition the probe to a warmer site and remove nail polish if possible
Rationale: Pulse oximetry accuracy is affected by poor peripheral perfusion (cold extremities), dark nail polish, and motion
artifact. Before treating an unexpected reading, the nurse should verify accuracy by repositioning the probe to a
better-perfused site (earlobe, forehead) and removing nail polish if present, then reassess.
Always verify equipment accuracy before treating an unexpected vital sign value.
Q7. Which factor is MOST likely to cause a FALSE LOW blood pressure reading?
A. Cuff too small for the patient's arm
B. Cuff too large for the patient's arm
C. Arm positioned above heart level
D. Cuff deflated too slowly
ANSWER: C. Arm positioned above heart level
Rationale: Positioning the arm ABOVE heart level during BP measurement causes a falsely LOW reading (gravity reduces
measured pressure). A cuff too small causes a falsely HIGH reading; a cuff too large causes a falsely LOW reading. The
arm should be supported at heart level for an accurate measurement.
Cuff too SMALL = falsely HIGH BP. Cuff too LARGE = falsely LOW BP. Arm above heart = falsely LOW.
Q8. A 2-year-old child has a respiratory rate of 38 breaths/min while calm and not crying. How should the
nurse interpret this finding?
A. This is tachypnea requiring immediate intervention
B. This is within the normal range for a toddler
C. This indicates respiratory distress
D. This is bradypnea for this age group
ANSWER: B. This is within the normal range for a toddler
Rationale: Normal respiratory rates vary significantly by age: newborns 30-60/min, infants 25-50/min, toddlers (1-3 yr)
20-40/min/min, school-age 18-30/min, adults 12-20/min. A respiratory rate of 38 in a calm toddler is within the normal range
and does not indicate distress.
Always interpret vital signs against AGE-APPROPRIATE normal ranges, not just adult norms.
