fundamentals of nursing

Nursing students need this book to pass; practicing nurses need it to stay sharp. It's the standard text that defines what nurses actually do and why. If you're entering the profession, teaching it, or just want to understand what your nurse is doing when she checks that chart—this is the source.

1. 1Chapter 1: Nursing Today

   Nursing Has a Definition, and It's Bigger Than Bedside Manner

   Florence Nightingale opened the first organized training program for nurses at St. Thomas' Hospital in London in 1860. The American Nurses Association eventually codified what all this training is for: 'Nursing is the protection, promotion, and optimization of health and abilities, prevention of illness and injury, alleviation of suffering through the diagnosis and treatment of human response, and advocacy in the care of individuals, families, communities, and populations.' Each state reinforces that boundary with a Nurse Practice Act that defines the scope of practice and shields the public from unsafe practitioners.

   The idea

   The definition locates nursing's expertise in the 'human response' to illness. That's why a Nurse Practice Act matters: it legally protects the territory where nursing judgment operates.

   Try this: Look up your state's Nurse Practice Act online and read the scope-of-practice section—it takes ten minutes and changes how you see your own authority.

2. 2Chapter 4: Theoretical Foundations of Nursing Practice

   Caring Is the Theory, Not Just the Vibe

   Madeleine Leininger built a theory: Culture Care Diversity and Universality.

   The idea

   Caring can be an object of study, not just a personality trait.

   Try this: Before your next patient interaction, ask one open question about what matters to them culturally or personally in how they receive care—then actually adjust something.

3. 3Chapters 15-20

   Five Steps, Every Patient, Every Shift

   The nursing process is a five-step clinical decision-making approach: assessment, diagnosis, planning, implementation, and evaluation.

   The idea

   The process makes nursing repeatable and auditable.

   Try this: Pick one problem you're managing—clinical or personal—and write a goal plus one measurable expected outcome with a deadline. Then evaluate against it in a week.

4. 4Chapter 5: Evidence-Based Practice

   Ask Better Questions: PICO(T)

   Evidence-based practice gives you a tool: the PICO(T) question format. P is the patient population of interest. I is the intervention of interest. C is the comparison of interest. O is the outcomes. T is time.

   The idea

   The format turns a vague hunch into a searchable, answerable question.

   Try this: Take one habit you're unsure about at work or home and force it into PICO(T) form—population, intervention, comparison, outcome, time. See how much clearer the question gets.

5. 5Chapter 16: Nursing Assessment

   Assessment Is Three Sources, Not One

   A complete nursing assessment pulls from three streams at once: the patient's history, the physical examination, and the review of laboratory and diagnostic test results.

   The idea

   The three-source model guards against anchoring on the first plausible story.

   Try this: Next time you gather information on any problem—yours or someone else's—deliberately pull from three independent sources before you decide anything.

6. 6Chapter 30: Health Assessment and Physical Examination

   Four Techniques, One Exam

   Every physical exam a nurse performs uses four primary techniques: inspection, palpation, percussion, and auscultation. Look first. Then touch. Then tap and listen to the sound. Then use the stethoscope.

   The idea

   Four techniques, drilled until they're automatic, turn a pair of hands and a stethoscope into diagnostic instruments.

   Try this: Practice deliberate observation: before you check anything (a symptom, a room, a person), spend thirty seconds just looking and naming what you see.

7. 7Chapter 29: Vital Signs

   Vital Signs Are Ranges, Not Numbers

   A healthy adult's oral temperature runs 36° to 38° C (96.8° to 100.4° F), averaging 37° C (98.6° F). The pulse sits between 60 and 100 beats per minute, averaging 80. Respiration runs 12 to 20 breaths per minute. Blood pressure should be a systolic less than 120 mm Hg and a diastolic less than 80 mm Hg.

   The idea

   'Normal' is a band, not a point, and the trend matters as much as the reading.

   Try this: Learn your own baseline: take your temperature, pulse, respiration, and blood pressure when you're well, so you know what 'normal for you' looks like.

8. 8Chapter 34: Infection Prevention and Control

   Six Links, One Broken Chain

   Every infection travels the same chain of six links: an infectious agent, a reservoir, a portal of exit, a mode of transmission, a portal of entry, and a susceptible host. The most powerful place to break it is also the simplest: hand hygiene, the single most important practice for reducing the transmission of infectious agents in health care settings.

   The idea

   The chain model turns infection control from vague vigilance into a targeting exercise.

   Try this: Count how many times you touch your face or a shared surface in the next hour—then wash your hands before your next meal and notice how often you'd normally skip it.

9. 9Chapter 38: Activity and Exercise

   What Bed Rest Actually Costs

   A patient is ordered on bed rest. The musculoskeletal system pays a price: muscle atrophy, loss of strength, and contractures.

   The idea

   Immobility is a treatment with side effects, not a neutral state.

   Try this: If you're ever on prescribed rest or working from bed during illness, set an hourly timer for gentle range-of-motion movements of every joint you can safely move.

10. 10Chapters 41, 42, 45, 46

    The Numbers That Keep You Alive

    The book gives normal adult values for arterial blood gases (pH 7.35 to 7.45, PaCO2 35 to 45 mm Hg, PaO2 80 to 100 mm Hg, HCO3- 22 to 26 mEq/L), serum sodium (135 to 145 mEq/L), potassium (3.5 to 5.0 mEq/L), and urine output (1500 to 2000 mL per 24 hours). It also lists the Acceptable Macronutrient Distribution Ranges for adults: 45% to 65% of total calories from carbohydrates, 20% to 35% from fat, 10% to 35% from protein.

    The idea

    These ranges are the body's operating manual in numbers.

    Try this: If you have recent lab work, find your sodium, potassium, and any blood gas or metabolic panel values and place each one inside its normal range—know your own numbers.

11. 11Chapter 50: Care of Surgical Patients

    Three Phases Around Every Operation

    Surgery has three phases of nursing care: preoperative, intraoperative, and postoperative.

    The idea

    Dividing perioperative care into three phases turns a chaotic, high-stakes process into a checklist of responsibilities.

    Try this: If you or someone close to you faces surgery, map the three phases in advance and write down one question to ask in each: before, during-planning, and after.

12. 12Chapter 47: Bowel Elimination

    The Maneuver You Shouldn't Do

    Straining on the toilet has a name: the Valsalva maneuver—holding the breath and contracting the abdominal muscles to increase intra-abdominal pressure and facilitate defecation. Nurses teach patients—especially those with cardiac conditions—not to do it.

    The idea

    The Valsalva maneuver is a behavior that feels natural and carries hidden risk.

    Try this: If you find yourself straining in the bathroom, stop and treat it as a signal—address the constipation itself with fluids, fiber, and timing rather than force.

Nursing students, new graduates preparing for practice, and anyone teaching or supervising clinical care. Also worth reading for patients and families who want to understand what nurses actually do and why.
