Study Notes
Cranial Nerves
- Olfactory nerve: Responsible for smell (sensory).
- Optic nerve: Responsible for sight (sensory).
- Oculomotor nerve: Controls eyelid opening, eye movement (superiorly, medially, diagonally), and pupil constriction (motor).
- Trochlear nerve: Moves the eye down laterally (motor).
- Trigeminal nerve: Facilitates chewing, jaw movements (motor); conveys sensory information from the eyes, nose, mouth, jaw, forehead, scalp, and facial skin (sensory).
- Abducens nerve: Responsible for lateral eye movement (motor).
- Facial nerve: Manages closing of eyes and mouth, facial expressions, salivation, and lacrimation (motor); involved in taste on the anterior tongue (sensory).
- Acoustic nerve: Responsible for hearing and balance (sensory).
- Glossopharyngeal nerve: Facilitates swallowing, gag reflex, saliva secretion (motor); involved in taste on the posterior tongue (sensory).
- Vagus nerve: Controls palate, pharynx, larynx (speech and swallowing) (motor); provides laryngeal and pharyngeal sensations, also involved in cardiovascular, respiratory, and digestive systems (sensorimotor).

- Dyspnea: Shortness of breath.
- Orthopnea: Breathing difficulty when lying down, alleviated by standing/sitting.
- Bradypnea: Abnormally slow breathing (<12 breaths/min).
- Tachypnea: Rapid breathing (>20 breaths/min).

- Apnea: Absence of breathing.
Skin and Color Changes
- Carotenemia: Yellowing of skin from high carotene intake; sclera remains white.
- Jaundice: Yellowing due to high bilirubin levels.

- Peripheral cyanosis: Blue discoloration of skin or membranes due to deoxygenated blood.
Additional Medical Conditions
- Hematemesis: Vomiting blood, related to gastrointestinal factors.
- Clostridium difficile: Leading cause of hospital-acquired diarrhea; prevalent in patients on antibiotics.

Male Health Concerns
- Erectile dysfunction (ED): Difficulty achieving/maintaining an erection, linked to conditions like diabetes and heart disease.
- Hypospadias: Urethral opening located on the penis’ underside.
- Testicular cancer risk factors: Family history, undescended testicle, previous cancer, HIV infection, and larger body size.
Pain Assessment Tools
- Numeric Rating Scale (NRS): Patients rate their pain from 0 (none) to 10 (worst pain).
- Wong-Baker Faces Pain Rating Scale: Uses facial expressions for pain intensity; suitable for ages 3 and up.
- Verbal Descriptor Pain Scale: Patients describe their pain severity.
- Iowa Pain Thermometer: Modified descriptor scale with varying pain levels.
Health Assessment Types
- Comprehensive assessment: Thorough review of all body systems; time-consuming.
- Focused assessment: Targets acute symptoms or problems.
- Follow-up assessment: Reviews new data since previous visits.
