• correct1. Air-fluid levels, This finding on an abdominal x-ray is the hallmark of a small-bowel obstruction. Samantha, age 28, is 100 lb overweight and wants to have a gastroplasty performed. In discussing this with her, what do you explain may happen by having this procedure? Developing diarrhea, Diarrhea is a common problem after a gastroplasty because of the induced malabsorption. Hepatitis D is an RNA virus that requires a coinfection with which of the following strains o...

P303, 312, 313 The gold standard of hearing evaluation includes pure tone audiometry with speech testing, as well as impedance (middle ear pressure) testing 1. Diagnosing Conductive vs. Sensorineural Hearing Loss A. History • Conductive: Ear pain, fullness, drainage, history of recurrent infections, trauma, cerumen impaction, surgery. • Sensorineural (SNHL): Gradual hearing loss (presbycusis), loud noise exposure, tinnitus, vertigo, ototoxic medications, sudden onset without infection. ...

Diagnosis Clinical Features • Appearance: Rough, scaly, erythematous or brownish papules/plaques on sun-exposed areas (face, scalp, ears, forearms, hands). • Texture: “Sandpaper-like” when palpated. • Symptoms: Usually asymptomatic but may itch, burn, or be tender. • Number: Often multiple lesions, may coalesce into larger patches. Risk Factors • Chronic sun exposure (UV radiation). • Fair skin, light hair, blue/green eyes. • Age > 40. • Immunosuppression (e.g., o...

acute otitis media (AOM): diagnosis and management: Diagnosis Typical Symptoms • Ear pain (otalgia), irritability in children. • Fever. • Hearing loss, ear fullness. • Sometimes otorrhea if tympanic membrane (TM) ruptures. Physical Exam • Tympanic membrane findings (key to diagnosis): o Bulging TM (most specific sign). o Decreased mobility on pneumatic otoscopy. o Erythema, opacity. o Middle ear effusion (fluid line, air-fluid bubbles). Diagnostic Criteria (per AAP/AAF...

Lab 6 Key Terms - Appendicular skeleton, meaning any muscle that acts on our arms or leg, on our shoulder blades, on any part of the pectoral girdle or pelvic girdle that is considered to be part of the appendicular skeleton. • Trapezius is a very large fan-shaped muscle. Its action is to elevate and depress the shoulder. So in actions of shrugging the shoulders, or pushing the shoulders down, the trapezius is working. It also helps to stabilize the scapula when the arm is doing other mo...
