Study Notes

Increased Risk of Exposure to Hepatitis Viruses

Healthcare workers may be exposed through needlestick injuries or contact with infected bodily fluids.
People with multiple sexual partners are at increased risk due to potential sexual transmission of hepatitis B and C.
Sharing needles or syringes raises the risk of hepatitis C and B for people who inject drugs.
Travelers to regions with high rates of hepatitis A or E are at increased risk.
Individuals with chronic liver disease are more susceptible to complications from all forms of hepatitis.
Infants born to infected mothers are at risk of contracting hepatitis B vertically during childbirth.

Issues from Prior Abdominal Surgeries or Trauma

Bands of scar tissue (adhesions) can form between organs, potentially causing bowel obstruction and chronic pain.
Surgical sites may become infected, leading to conditions like abscesses or peritonitis.
Changes in peristalsis, motility, or function of the intestines can occur after abdominal surgery or trauma, potentially leading to constipation or diarrhea.
Trauma may directly injure organs, leading to hemorrhage or organ failure.
Surgical alterations can affect the normal passage of food or waste, which may require dietary changes or interventions.

Medications with Adverse GI Effects

Nonsteroidal Anti-inflammatory Drugs (NSAIDs) like Aspirin and Ibuprofen can cause gastric irritation, ulcers, and gastrointestinal bleeding due to their effect on the gastric mucosa.
Prolonged use of Corticosteroids (steroids) can increase the risk of peptic ulcers and gastric bleeding.
Antibiotics can alter gut flora, potentially leading to diarrhea, including Clostridium difficile infections.
Many chemotherapeutic drugs can cause nausea, vomiting, mucositis, and changes in bowel habits.

Normal vs. Abnormal Findings

Normal findings include full range of motion without pain, no swelling, tenderness, or deformities.
The most common site of sprains is the ankle due to its anatomical structure and susceptibility to injury when landing from jumps or twists.
Gouty arthritis symptoms include sudden onset of severe pain, redness, swelling, and warmth in the affected joint, often the big toe.
Plantar fasciitis, characterized by inflammation of the plantar fascia, is a common cause of heel pain.

Testing for ROM in the Ankle

Dorsiflexion involves moving the foot up toward the shin.
Plantarflexion involves pointing the foot downwards.

Four Major Divisions of the Brain

Frontal Lobe: Responsible for high-level cognitive functions, including reasoning, problem-solving, planning, and controlling voluntary movements. It also plays a critical role in personality and decision-making.
Parietal Lobe: Processes sensory information related to touch, temperature, pain, and proprioception (spatial awareness). It integrates sensory input to formulate a coherent understanding of the environment.
Temporal Lobe: Involved in auditory processing, memory, and the comprehension of language. It contains structures essential for memory formation and retrieval.
Occipital Lobe: Primarily responsible for visual processing. It interprets visual stimuli and is involved in visual perception and recognition.

Broca's and Wernicke’s Areas

Broca's Area: Located in the left frontal lobe, responsible for speech production and language processing. Damage to this area can result in Broca’s aphasia, characterized by difficulty in speech production but preserved comprehension.
Wernicke's Area: Located in the left temporal lobe, responsible for language comprehension. Damage to this area can result in Wernicke’s aphasia, where a person can produce fluent speech but lacks meaning or coherence in what they say.

Key Terms

Orthostatic Hypotension: A drop in blood pressure upon standing that leads to dizziness.
Paresthesia: Abnormal sensation (e.g., tingling, "pins and needles").
Tinnitus: Ringing or noise in the ears.
Dysarthria: Difficulty in articulating words due to muscle weakness.
Dysphasia: Difficulty in language processing or comprehension.
Aphasia: Complete inability to communicate effectively using speech or language.
Dysphagia: Difficulty swallowing.
Fasciculations: Involuntary muscle contractions that can be observed as twitching.
Tremors: Involuntary shaking or rhythmic movement of a body part.
Myoclonus: Sudden, brief jerking movements of a muscle or group of muscles.
Amnesia: Loss of memory, either partially or completely.
Delirium: Acute confusion and disorientation, often reversible.
Dementia: A progressive decline in cognitive function affecting daily activities.

Older Adult Considerations

Assess for changes in sensory perception (hearing and vision) which may impact communication.
Be mindful of signs of forgetfulness, confusion, or changes in alertness (cognitive function).
Observe for tremors, weakness, or difficulty with movements that may indicate neurological issues (motor function).
Speak clearly and allow extra time for them to respond, considering potential speech or language difficulties.

Questions to Ask About Muscle Control

Have you noticed any weakness in your muscles?
Are you experiencing any difficulty with coordination or balance?
Have you had any recent falls or near falls?
Do you have a history of conditions like spinal cord injury, multiple sclerosis, or Parkinson’s disease that may affect muscle control?

Differentiating Between Recent vs. Remote Memory

Recent Memory: Refers to the ability to recall information that has been learned or experienced, typically within the last few days to weeks (e.g., recent events, conversations, or appointments).
Remote Memory: Involves recalling information from the distant past (e.g., childhood memories, past experiences, or historical events).

Past Health History

It is important to inquire about past medical history, including any surgeries, traumas, and existing medical conditions that may affect the neurological system.

Hypoglossal Nerve (Cranial Nerve XII)

Function: Motor; it controls the movement of the tongue, essential for speech and swallowing.
Assessment: Ask the patient to stick their tongue out; then move it with resistance by tongue depressor.
Normal findings: Symmetric, free-moving, clear speech.
Abnormal findings: Deviation of the tongue, weakness, atrophy, dysarthria or difficulty speaking.

Assessment of Movement, Balance, and Coordination

Condition and Movement of Muscles:
- Assessment: Observe the patient's ability to move limbs and assess for any involuntary movements or abnormalities in posture.
- Normal Findings: Smooth, voluntary movements; appropriate muscle tone; no tremors or fasciculations.
- Abnormal Findings: Difficulty in movement, rigidity, tremors, or involuntary movements like dyskinesia.
Strength and Tone of Muscles:
- Assessment: Test muscle strength through resistance testing (e.g., bicep curls or leg lifts) and assess muscle tone by observing resistance to passive movement.
- Normal Findings: Equal strength bilaterally; appropriate muscle tone (not too stiff or floppy).
- Abnormal Findings: Muscle weakness (partial or complete), atrophy, or abnormal muscle tone (hypertonia or hypotonia).
Gait and Balance:
- Assessment: Ask the patient to walk normally and then observe gait for symmetry, balance, and coordination.
- Normal Findings: Even and balanced gait with arms swinging naturally at sides.
- Abnormal Findings: Shuffling, limping, wide-based gait, unsteadiness, or difficulty turning.
Tandem Walking:
- Assessment: Instruct the patient to walk in a straight line placing the heel of one foot directly in front of the toes of the other foot.
- Normal Findings: Steady and coordinated movement without loss of balance.
- Abnormal Findings: Loss of balance, inability to walk in a straight line, or difficulty maintaining tandem gait.
Romberg Test:
- Assessment: Have the patient stand with feet together and arms at their sides. Instruct them to close their eyes and maintain the position for 20-30 seconds.
- Normal Findings: The patient should maintain balance without swaying or falling.
- Abnormal Findings: Swaying, opening eyes for balance, or falling indicates impaired proprioception or vestibular function.

Assessment of Sensory Function

Light Touch:
- Assessment: Use a cotton ball or a soft object. Apply light touch on various areas of the skin, asking the patient to indicate when they feel it.
- Normal Findings: The patient accurately reports feeling touch where applied.
- Abnormal Findings: Diminished sensation or loss of touch perception (hypoesthesia or anesthesia).
Pain:
- Assessment: Use a sharp object (e.g., pin) or a safety pin. Apply a light pinch to different areas and ask the patient to identify sharp versus dull.
- Normal Findings: The patient can accurately differentiate between sharp and dull sensations.
- Abnormal Findings: Inability to recognize sharpness or presence of pain when it should not be felt.
Temperature:
- Assessment: Use test tubes filled with warm and cold water (or a thermal stimulator). Apply to various skin areas while asking the patient to identify temperature.
- Normal Findings: The patient accurately identifies hot and cold sensations.
- Abnormal Findings: Inability to sense temperature differences (may indicate peripheral neuropathy).
Vibratory Sensation:
- Assessment: Use a low-pitched tuning fork (typically 128 Hz). Strike the fork and place it on bony prominences.
  - Locations to Assess: Distal interphalangeal joints of the fingers (e.g., index fingers), the big toe (first metatarsal), other bony areas like the wrist and ankle.
- Normal Findings: The patient feels the vibration while the fork is placed on the bony areas.
- Abnormal Findings: Diminished or absent vibratory sensation, which may suggest peripheral neuropathy or other neurological conditions.
Sensitivity to Position (Proprioception):
- Assessment: Hold the patient’s toe or finger by the sides and move it up or down. Ask the patient to identify the direction of movement.
- Normal Findings: The patient can accurately identify the position movements.
- Abnormal Findings: Inability to correctly identify the direction of movement may indicate a proprioceptive deficit.
Tactile Discrimination (Fine Touch):
- Assessment: Use a cotton swab or a two-point discriminator to assess the ability to feel light touch.
- Normal Findings: The patient can perceive light touch accurately.
- Abnormal Findings: Insensitivity to light touch may indicate sensory loss.
Point Localization:
- Assessment: Touch the patient in various locations on the skin and ask them to identify where they were touched without looking.
