Exam 4 Flashcards
(113 cards)
S&S of appendicitis
-Awakens at night with vague periumbilical pain
-Pain worsens over 4 hours
-Pain eventually migrates to RLQ and is worsened with movement
-Anorexia
-Vomiting
-Diarrhea
-McBurney’s sign, Rovsing’s sign, psoas sign, obturator sign
-Involuntary guarding
Diagnostic tests for appendicitis
-Rovsing’s: pressure in LLA elicits pain in RLQ, Psoas, Obturator, rebound tenderness (Bloomberg’s sign)
-CBC: may or may not have elevated WBCs, will have shift to the left w/ increased neurophils/bands
-US, CT with contrast (highest accuracy)
Describe the obturator and psoas signs to assess for appendicitis
Obturator- Flex the right leg, rotate the hip internally while patient is supine; positive if this illicits pain
Psoas- patient lies supine or on left side and flexes right hip (lifts leg) against pressure from the examiner- positive if this causes pain
What are the different types of knee injuries?
-Osteochondritis dissecans- bone or cartilage separates from the rest of the bone due to stress or trauma
-Patellar dislocation-patellar malalignment
-ACL sprain- acute injury from twisting or hyperextension
-MCL sprains- most commonly injured due to valgus (inward) stress to an extended knee
-Meniscal tear- significant injury, uncommon in youth <12 years of age
-Quadriceps contusion- bruising of quadriceps muscle, often from sports injury
How do you diagnose different types of knee injuries?
-Valgus/Varus stress: checks lateral amd medial collateral ligaments
-McMurray test for meniscus cartilage tear
-Lachman test (ACL injury)
-X-ray, CT, MRI (ligament or meniscus tear)
What are some exam techniques for diagnosing knee injury? Examples of a few are Lachman and McMurray tests
-Valgus/Varus stress: examiner holds knee joint and ankle joint and moves knee from side to side
-McMurray: examiner grasps supine patient’s heel and knee, knee is maximally flexed and rotated internally (lateral meniscus) and externally (medial meniscus)
-Lachman test- flex the knee to 20-30 degrees and attempt to pull tibia anterior to femur
What is the first line treatment for UTIs in children?
-Bactrim 8-10mg/kg/day
-If younger than 3 months old: amoxicillin or augmentin
-Keflex and other cephalosporins (Cefdinir) good for E. Coli
How would a UTI presentation differ for different ages such as toddler versus school-aged children?
Infants: FTT, diarrhea, jaundice, polyuria, malodorous urine
Children < 2 years: fever, vomiting, anorexia, FTT
-Children 2-5 yrs: fever, abdominal pain
-School-aged: Classic signs such as dysuria, frequency, urgency, CVA tenderness
Describe diagnosis and management of hydrocele
-Dx: Transillumination (pink or red), unilateral edema, asymmetry, non-communicating (blue-tinged) or communication (fluid comes and goes)
-Management: Refer to urology if persists after 1 year
Describe diagnosis and management of hypospadias
-Dx: Physical exam shows dorsally hooded foreskin in newborn
-Management: Referral to urologist, surgery
What is the difference between a muscle sprain and strain?
-Sprain- Injury to the ligaments and capsule at a joint or the body. Graded 1-3 with 3 being a complete ligament tear
-Strain- an injury to muscles or tendons
S&S of Legg-Calves-Perthes disease
-Unilateral hip or thigh pain that can radiate to the knee
-Painless limp
-Limp worsens after activity
-Reduced ROM of hip
-NSAIDS often don’t help with pain
Diagnostic criteria for Legg-Calves-Perthes disease
-X-ray: AP & frog leg lateral will shows flattening and fragmentation of the femoral head
-MRI may show osteonecrosis
S&S of slipped capital femoral epiphysis
-Limping, knee and/or hip pain
-Pain worse with activity
-May be unable to bear weight
-Loss of internal rotation with flexion
-Affected extremity may be shorter
-Loss of abduction & extension
Diagnostics & Management for slipped capital femoral epiphysis
Dx. X-ray shows widening of the epiphysial line and displacement of the femoral head
Mngmnt: Referral for ortho, non-weight bearing until surgical eval
How do you diagnose scoliosis?
-Forward bend test (Adam’s): patient leans forward with his or her feet together and ben 90 degree at the waist
-Other PE findings: shoulders are different heights, uneven waste, dimples or color changes over spine, leaning of body to one side
-X-ray: standing, full length posteroanterior and lateral views of spine- evaluates Cobb angle
What is the treatment for diarrhea in children?
-Rehydration
-Pre/Probiotics
How would you evaluate a child for dehydration?
-Sunken anterior fontanel
-Tachycardia, decreased cap refill
-Decreased UOP (ask about wet diapers)
-Increased urine specific gravity
-Decreased BP is late finding (severe)
-Evaluate mucous membranes
S&S of pyloric stenosis
-Regurgitation during first few weeks of life
-Projectile emesis begins at 2-3 weeks of life
-Constantly hungry
-Weight loss
-Dehydration
-Constipation
-Emesis may contain blood
S&S of intussusception
-Most common cause of intestinal obstruction < 2 years of age, more common in boys
-Screaming and drawing up of legs with periods of rest
-Stool with blood
-Sausage-like mass may be felt in RLQ (Dance’s sign)**
-Abdominal distention and tenderness
Diagnostics & management for intussusception
-Abdominal US
-Consult pediatric surgeon
-Air contrast enema is diagnostic and usually curative
-Risk of recurrence in 24 hours
S&S of Hirschprung’s disease
-Failure to pass meconium in first 48 hours of life
-FTT, constipation, abdominal distention, diarrhea, vomiting
How much percentage of body weight loss occurs in dehydration?
Mild: up to 5% in infants and 3% in children
Severe: 10-15% in infants, 9% in children
What are common bacterial causes of dehydration in children?
E. coli, salmonella, shigella
