NURS_101: Kozier & Erb's Fundamentals of
Nursing Prep with Detailed Rationales
Course Code: NURS_101
Course Name: Fundamentals of Nursing
Topic: Vital Signs, Nursing Process, Safety, Medication Administration, Infection
Control, and Evidence-Based Practice
Academic Year: 2026/2027
Module 1: Vital Signs & Patient Assessment
Question 1
A nurse is assessing the vital signs of an adult client and notes a respiratory rate
of 24 breaths per minute with shallow chest expansion. Which term should the
nurse use to document this finding accurately?
A) Bradypnea
B) Tachypnea
C) Hyperpnea
D) Cheyne-Stokes
CORRECT ANSWER: B) Tachypnea
RATIONALE: According to Kozier & Erb's Fundamentals of Nursing , the
normal respiratory rate for a healthy adult is 12 to 20 breaths per minute. A rate
,greater than 20 breaths per minute is classified as tachypnea . Bradypnea (Option
A) refers to a rate slower than 12 breaths per minute. Hyperpnea (Option C)
involves deep, rapid breathing. Cheyne-Stokes (Option D) is an irregular, rhythmic
pattern alternating between periods of apnea and hyperventilation, typically seen in
terminal illness or severe heart failure.
Question 2
When assessing a client's blood pressure , the nurse inflates the cuff 30 mmHg
above the point where the radial pulse disappears. What is the clinical purpose of
this specific action?
A) To prevent venous congestion in the arm.
B) To minimize the risk of procedural pain.
C) To avoid missing an auscultatory gap.
D) To ensure correct alignment of the bladder.
CORRECT ANSWER: C) To avoid missing an auscultatory gap.
RATIONALE: An auscultatory gap is a temporary disappearance of Korotkoff
sounds typically occurring during the latter part of Phase I and Phase II. If the
nurse does not inflate the cuff high enough, the true systolic pressure may be
underestimated because the nurse begins listening during the gap. Inflating the cuff
30 mmHg above the palpatory systolic pressure ensures the nurse bypasses this gap
entirely. Options A, B, and D do not describe the physiological or mechanical
purpose of this step.
Question 3
The nurse is preparing to measure an apical pulse on a patient. At which
anatomical location should the nurse place the stethoscope diaphragm?
A) Second intercostal space, right sternal border.
B) Fourth intercostal space, left sternal border.
C) Fifth intercostal space, left midclavicular line.
D) Fifth intercostal space, anterior axillary line.
CORRECT ANSWER: C) Fifth intercostal space, left midclavicular line.
RATIONALE: The apical pulse , or point of maximal impulse (PMI), is
anatomically located at the fifth intercostal space (ICS) along the left
midclavicular line (MCL) in an adult client. Placing the stethoscope here allows
the nurse to listen directly over the apex of the heart for a full 60 seconds to detect
,irregularities. Option A corresponds to the aortic area. Option B corresponds to the
tricuspid area. Option D is too far lateral.
Question 4
A nurse notes that an older adult client has a core body temperature of 36.0°C
(96.8°F) . How should the nurse interpret this finding based on standard
developmental changes?
A) The client has an active systemic infection.
B) The client is experiencing acute heat stroke.
C) This is a normal physiological variant for older adults.
D) The thermometer is broken and needs to be replaced.
CORRECT ANSWER: C) This is a normal physiological variant for older
adults.
RATIONALE: Older adults naturally exhibit a lower baseline body
temperature than younger adults due to physiological changes such as decreased
subcutaneous fat, reduced metabolic rate, and diminished thermoregulatory
efficiency. A baseline temperature around 36.0°C (96.8°F) is expected and
considered normal. It does not indicate infection (Option A), which would usually
present as a relative elevation, nor heat stroke (Option B).
Question 5
Which physiological mechanism is responsible for the primary source of heat
loss from the human body to the surrounding air without direct physical contact?
A) Conduction
B) Convection
C) Radiation
D) Evaporation
CORRECT ANSWER: C) Radiation
RATIONALE: Radiation is the transfer of heat from the surface of one object
to the surface of another without direct physical contact, mostly in the form of
infrared rays. It accounts for roughly 60% of total body heat loss in a temperate
indoor environment. Conduction (Option A) requires direct touch. Convection
(Option B) involves air currents. Evaporation (Option C) involves moisture turning
to vapor.
, Module 2: The Nursing Process & Clinical Reasoning
Question 6
During the assessment phase of the nursing process, the nurse collects both
objective and subjective data . Which of the following is an example of objective
data?
A) The client states, "My stomach hurts badly."
B) The client rates their anxiety as a 7 out of 10.
C) The client's surgical wound has 15 mL of serosanguineous drainage.
D) The client complains of feeling dizzy when standing up.
CORRECT ANSWER: C) The client's surgical wound has 15 mL of
serosanguineous drainage.
RATIONALE: Objective data (also known as signs) are measurable,
observable, or verifiable facts obtained through physical examination, laboratory
tests, or diagnostic procedures. Measurable wound drainage is objective. Options
A, B, and D are subjective data (symptoms) because they rely entirely on the
client's personal statements, perceptions, and feelings, which cannot be directly
verified or measured independently by the clinician.
Question 7
The nurse writes a nursing diagnosis for a client: Ineffective Airway Clearance
related to retained secretions as evidenced by thick sputum and rhonchi. What is
the "related to" phrase representing in this three-part diagnosis?
A) The defining characteristics.
B) The etiology or contributing factors.
C) The diagnostic label.
D) The patient outcome criteria.
CORRECT ANSWER: B) The etiology or contributing factors.
RATIONALE: In a standard NANDA-I three-part nursing diagnosis layout
(Problem, Etiology, Signs/Symptoms), the "related to" (r/t) clause specifies the
etiology or pathophysiological factors driving the problem. The diagnostic label
(Option C) is Ineffective Airway Clearance . The defining characteristics (Option
A) follow the "as evidenced by" phrase.
