Evidence-Based Practice
- Credible research informs nursing interventions and clinical judgment.
Guiding Principles in Nursing
- Code of Ethics defines nursing values.
- Scope and Standards of Practice details nursing care and expected competency.
- Policies and Procedures are rules and regulations within healthcare organizations.
- Nurse Practice Act is state regulations that guide nursing care.
- Self-determination requires nurses to act professionally.
Nursing Process (ADPIE)
- Assessment involves collecting subjective and objective data.
- Diagnosis involves identifying patient problems using NANDA diagnoses.
- Planning involves establishing SMART goals (Specific, Measurable, Achievable, Relevant, Time-bound).
- Implementation involves carrying out nursing interventions (independent, dependent, collaborative).
- Evaluation involves checking if goals were achieved and revising the plan if needed.
Infection Control & Safety
Infection Control
- Standard Precautions are used for all patients, including hand hygiene and gloves for bodily fluids.
- Transmission-Based Precautions include:
- Contact: Gown and gloves for infections like MRSA and C. diff.
- Droplet: Mask needed within 3 feet for influenza and pertussis.
- Airborne: N95 mask and negative airflow room for TB, measles, and varicella.

Vital Signs & Physical Assessment
Normal Ranges
- Temperature: 36.5-37.5°C (97.7-99.5°F).
- Heart Rate: 60-100 bpm.
- Respiratory Rate: 12-20 breaths/min.
Theoretical Frameworks in Nursing
- Key frameworks include Kohlberg, Maslow, Erikson, and Piaget, which are commonly found on nursing exams
- These frameworks help nurses understand patients' behavior, leading to better caregiving
- This enhances nursing communication and the nurse/patient relationship by understanding patient motives, needs, and perceptions.
Kohlberg's Theory of Moral Development
- Focuses on thinking, reasoning, and decision-making across the lifespan.
- Three stages: preconventional, conventional, and postconventional.
- Preconventional: From birth to age 5, actions are taken to avoid consequences or gain rewards; sticker charts are effective
- Conventional: From age 6 to 12, children consider how their actions affect others and follow social norms, seeking approval
- Postconventional: Begins around age 13; abstract ideas and other perspectives influence decision-making.
Maslow's Hierarchy of Needs
- Organizes human needs hierarchically, with physiological needs at the base.
- Psychosocial, higher-level needs can't be met until basic needs are met.
- Nurses should prioritize physiological needs (like pain and nutrition) before psychosocial needs (like body image).
- Physiological needs: Biological survival needs like water, food, and shelter.
- Safety: Includes security, employment, and access to resources.
- Love and belonging: Includes relationships with friends, family, and significant others.
- Self-esteem: Includes achievement and respect from others and self-respect.
- Self-actualization: Includes pursuing inner talents, fulfillment, and achieving personal goals.
Erikson's Stages of Psychosocial Development
- Describes key stages in human development and the psychosocial crisis at each stage
- Psychosocial crisis: A conflict involving mental health and the social environment during each stage
- Birth to 1 year: Trust vs. mistrust, learning whether needs are met when expressed.
- 1 to 3 years: Autonomy vs. shame and doubt, learning to act on the world, but can internalize shame if autonomy is suppressed.
- 3 to 6 years: Initiative vs. guilt, taking initiative and asserting themselves, but may internalize guilt if prevented.
- 6 to 12 years: Industry vs. inferiority, becoming part of "industry" through school and activities, risking feelings of inferiority.
- Nurses can support hospitalized children in this stage by providing crafts or ensuring they receive homework.
- 12 to 18 years: Identity vs. confusion, forming identity but may experience confusion about their place in the world.
- 18 to 40 years: Intimacy vs. isolation, seeking intimacy but risking isolation if unsuccessful.
- 40 to 65 years: Generativity vs. stagnation, finding life's work and purpose or feeling stuck.
- 65 years and older: Integrity vs. despair, reflecting on life with pride or feeling despair.
Piaget's Theory of Cognitive Development
- Describes perception and cognition across the lifespan.
- Sensorimotor stage (birth to 2 years): Learning through senses and movement, developing object permanence
- Object permanence: Understanding that objects continue to exist even when out of sight. Absence of this explains why peekaboo is fun for babies.
- Preoperational stage (2 to 7 years): Magical thinking (believing magic is real) and animism (attributing human characteristics to inanimate objects).
- Concrete operational stage (7 to 11 years): Understanding cause and effect, and the concept of conservation.
- Conservation is the idea that matter does not change when its form is altered.
- Formal operational stage (11+ years): Developing abstract thinking, deductive reasoning, and logic-based problem-solving.
- Abstract thinking: The ability to think about concepts and abstract ideas.

- Cranial nerves are labeled with Roman numerals I to XII, according to their location in the brain.
- Cranial nerve 1: Olfactory nerve (CN I) - sensory
- Cranial nerve 2: Optic nerve (CN II) - sensory
- Cranial nerve 3: Oculomotor nerve (CN III) - motor
- Cranial nerve 4: Trochlear nerve (CN IV) - motor
- Cranial nerve 5: Trigeminal nerve (CN V) - mixed
- Cranial nerve 6: Abducens nerve (CN VI) - motor
- Cranial nerve 7: Facial nerve (CN VII) - mixed

- Cranial nerve 12: Hypoglossal nerve (CN XII) - motor
- The mnemonic "Oh Oh Oh To Touch And Feel Very Good Velvet — Ah, Heaven!" is one way to remember the 12 cranial nerves.
Olfactory Nerve (CN I)
- Transmits information about the sense of smell to the brain.
- Olfactory receptors send impulses to the cranial cavity and then to the olfactory bulb after fragrant molecules are inhaled.
- Olfactory neurons and nerve fibers connect with other nerves, passing into the olfactory tract.
- The olfactory tract goes to the frontal lobe and other memory and smell notation areas of the brain.
Optic Nerve (CN II)
- Transmits visual information to the brain.
- Light enters the eye and hits the retina, which contains photoreceptors called rods and cones.
- Cones in the central retina enable color vision.
- Rods in the peripheral retina are responsible for noncolor vision.
- Photoreceptors carry signal impulses along nerve cells to form the optic nerve.
- Most optic nerve fibers cross into the optic chiasm, then project to the primary visual cortex in the occipital lobe.
- The occipital lobe handles visual information.
Oculomotor Nerve (CN III)
- Controls muscle movements of the eyes.
- Provides movement to most muscles that move the eyeball and upper eyelid (extraocular muscles).
- Helps with involuntary eye functions, such as the sphincter pupillae muscle constricting the pupil in bright light and relaxing in dim light.
- Ciliary muscles help the lens adjust to short-range and long-range vision.
Trochlear Nerve (CN IV)
- Also involved in eye movement.
- Powers the contralateral superior oblique muscle, allowing the eye to point downward and inward.
Trigeminal Nerve (CN V)
- The largest cranial nerve, with both motor and sensory functions.
- Motor functions help with chewing and clenching teeth and gives sensation to muscles in the tympanic membrane.
- Sensory division has three parts: ophthalmic, maxillary, and mandibular.
- Ophthalmic part: Sensation to parts of the eyes, nasal mucosa, and skin on the nose, eyelid, and forehead.
- Maxillary part: Sensation to the middle third of the face, side of the nose, upper teeth, and lower eyelid.
- Mandibular part: Sensation to the lower third of the face, tongue, oral mucosa, and lower teeth.
- Trigeminal neuralgia is a common disorder causing intense pain and facial tics.
Abducens Nerve (CN VI)
- Helps control eye movements.
- Helps the lateral rectus muscle turn the gaze outward.
- It starts in the pons of the brainstem, enters Dorello’s canal, travels through the cavernous sinus, and ends at the lateral rectus muscle.
Facial Nerve (CN VII)
- Has both motor and sensory functions.
- Consists of four nuclei serving different functions:
- Movement of muscles producing facial expression.
- Movement of the lacrimal, submaxillary, and submandibular glands.
- Sensation of the external ear.
- Sensation of taste.
- The four nuclei originate in the pons and medulla, joining together to travel to the geniculate ganglion.
- Bell’s palsy is a common disorder causing paralysis on one side of the face and possible loss of taste sensation.
Vestibulocochlear Nerve (CN VIII)
- Helps with hearing and balance.
- Contains two components: the vestibular nerve and the cochlear nerve.
- Vestibular nerve: Helps the body sense changes in the position of the head, maintaining balance.
- Cochlear nerve: Helps with hearing; inner hair cells and the basilar membrane vibrate in response to sounds.
- Fibers combine in the pons and exit the skull via the internal acoustic meatus in the temporal bone.
Glossopharyngeal Nerve (CN IX)
- Possesses both motor and sensory functions.
- Sensory function receives information from the throat, tonsils, middle ear, and back of the tongue, also has a role in taste sensation on the back of the tongue.
- The motor division provides movement to the stylopharyngeus, a muscle allowing the throat to shorten and widen.
- Starts in the medulla oblongata and leaves the skull through the jugular foramen, leading to the tympanic nerve.
Vagus Nerve (CN X)
- Has a range of functions, providing motor, sensory, and parasympathetic functions. -Sensory part: Sensation to the outer ear, throat, heart, and abdominal organs, also plays a role in taste sensation. -Motor part: Movement to the throat and soft palate. -Parasympathetic function: Regulates heart rhythm and innervates smooth muscles in the airway, lungs, and gastrointestinal tract.
- Vagus nerve stimulation therapy is used to treat epilepsy, depression, and anxiety.
- The vagus nerve is the longest cranial nerve, starting in the medulla and extending to the abdomen.
Accessory Nerve (CN XI)
- Provides motor function to some muscles in the neck.
- Controls the sternocleidomastoid and trapezius muscles for rotating, extending, and flexing the neck and shoulders.
- Separates into spinal and cranial parts.
- Spinal component: Starts in the spinal cord and travels into the skull through the foramen magnum, meeting the cranial component and exiting along the internal carotid artery.
- Cranial part: Combines with the vagus nerve.
Hypoglossal Nerve (CN XII)
- A motor nerve supplying the tongue muscles and originates in the medulla.
- Disorders can cause paralysis of the tongue, often on one side.
- The trochlear nerve is the shortest cranial nerve because it has the lowest number of axons.
