The following are risk factors for hypertension in children and teens (choose all that apply): being obese. being exposed to second - hand smoke. 2. In evaluating a 9 - year - old child with a healthy BMI during a well visit , a comprehensive cardiovascular evaluation should be conducted by the following methods (choose all that apply): Obtain fasting lipid profile. / Assess diet and physical activity. 3.

    2 ≤125 mg/dL or 7 mmol/L) or impaired glucose tolerance (2 -hour post prandial ≥140 -199 mg/dL or 7.8 mmol/L-11 mmol/L) or an A1C of 5.7% to 6.4%. True 11. Screening for type 2 diabetes begins at age _ 10 or at onset of puberty and continues every 2 years until adulthood; at that point, the adult guidelines should be followed. 12. The AAP screening guidelines for total cholesterol levels in children and adolescents aged 2 to 19 years old are as follows: Acceptable level is < 170 mg/dL (<9.4 mmol/L), borderline is 170 - 199 mg/dL (9.4 mmol/L - 11 mmol/L), and high is >200 mg/dL (≥11.1 mmol/L) 13. Children should be screened for family history of cardiovascular disease (CVD) beginning at age _ 3 and should be periodically updated annually or as required by risk factors during non - urgent health visits. 14. For at - risk children, fasting lipid levels should be tested after _ _2 years of age (but no later than 10 years of age) and should be retested in 3 - 5 years if the values fall within the reference range. 15. Body mass index (BMI ) should be measured beginning at age 2 .

    3 16. For children between 12 months and 2 years of age for whom overweight or obesity is a concern , the use of REDUCED fat milk would be appropriate. 17. Beginning at age _5 if BMI is ≥ 85th percentile, intensify dietary and activity changes to the parent. 18. Infection with Corynebacterium diphtheriae usually causes: Pseudomembranous pharyngitis 19. The tetanus infection is caused by CLOSTRIDIUM TETANI , an anaerobic, gram - positive, spore - forming rod. This organism is found in soil and is particularly potent in manure. 20. Sources of lead that can contribute to plumbism include select traditional remedies such as azarcon and greta. True 21. Patients with plumbism present with which kind of anemia? Microcytic, hypochromic 22. Intervention for a child with a lead level of 5 to 44 mcg/dL usually includes all of the following except: Chelation therapy 23. Ingested lead inactivates heme synthesis by inhibiting the insertion of iron into the protoporphyrin ring. This leads to the development of what kind of anemia? microcytic, hypochromic 24. Basophilic stippling is often noted on red blood cell morphology in lead poisoning . 25. Lead is significantly toxic to the solid organs, bones, and nervous system 26. Long - term complications of LEAD poisoning include behavior or attention problems, poor academic performance, hearing problems, kidney damage, reduced IQ, and slowed body growth. 27. Unless deleading procedures have been performed, however, most homes built before 1957 contain lead-based paint. 28. A diet low in calcium , iron, zinc, magnesium, and copper and high in fat, which is a typical diet for children living in poverty , enhances oral lead absorption 29. In older homes, the point of greatest risk is the _ _ window because their sills and the putty have high lead concentration. Because toddlers (age 2 to 3) are the ideal height to reach them and are often drawn to open ones, they are at greatest risk and summer is the riskiest season. window 30. Symptoms of elevated LEAD levels include abdominal pain and cramping, aggressive behavior, anemia, constipation, difficulty sleeping, headaches, irritability, loss of previous developmental skills in young children, lowappetite and energy, and reduced sensations. Very high levels can result in vomiting, staggering walk, muscle weakness, seizures, or coma. 31. A measure of 5 mcg/dL is now used to identify children with elevated blood lead levels. 32. Most children with lead levels of 5-44 mcg/dL are treated with removal from the source, improved nutrition, and IRON therapy. 33. Those with lead levels of 45-50 mcg/dL are treated with a CHELATION agent such as succimer,

    4 in addition to the previously listed interventions. 34. For children with lead levels of greater than 51 mcg/dL, hospital admission with expert evaluation is likely the most prudent course to avoid serious problems (including ENCEPHALOPATHY ) associated with markedly elevated lead levels 35. Which of the following represents the best choice of clinical agents for a child who has had a history of penicillin allergy who requires antimicrobial therapy? Cefdinir

    5 36. The clinical presentation of UTI in children can be without the classic symptoms such as frequency, dysuria, or flank pain. True 37. In younger children, UTI often manifests as IRRITABLITY_, LETHARGEY , and FEVER with no obvious focal infectious source. 38. Older children with UTI often present with ABDOMINAL pain, unexplained fever, or both; as children approach puberty, flank pain becomes more common 40. UTI should be considered in infants and young children 2 months to 2 years old with unexplained fever, particularly in boys younger than 6 months and girls younger than 2 years who have a temperature greater than or equal to 39°C (≥102.2°F). 41. A URINALYSIS should be obtained in a child with unexplained fever or symptoms that suggest a UTI; however, 20% from UTI cases return a false-negative result. 42. Any of the following findings are suggestive, although not diagnostic, of UTI: positive leukocyte esterase, positive nitrite, more than 5 white blood cells (WBCs) per high-power field in spun specimen, and bacteria present in unspun Gramstained specimen. 43. An acceptable method because of the low rate of skin and fecal contamination is a urine specimen collection via bag or from the diaper. False, unacceptable because of the high rate of contamination 44. a single documented UTI in a child must be taken seriously. If an infant or young child 2 months to 2 years old with suspected UTI is assessed as toxic, dehydrated, or unable to retain oral intake, HOPITALIZATION is advised. 45. Oral amoxicillin, TMP-SMX, or a second-or third-generation CEPHALOSPORIN_ is recommended as options for initial therapy for UTI in children 46. The use of _TMP-SMX has a small risk of treatment failure. 47. Current evidence-based practice recommendations for UTI in Children indicate a _7 to 14 day course of antibiotics because the outcomes are superior to a 1-to 3-day course in preventing spread of infection and subsequent renal scarring. 48. Although fluoroquinolone antibiotics have not been widely used in children, ciprofloxacin is approved by the U.S. Food and Drug Administration (FDA) for use in pediatric patients for the treatment of UTI; this use is approved starting at age 1 years old. 49. Urinary tract imaging should be considered for all children with UTI , particularly if this occurs before toilet training. true 50. The two mainstays for imaging for UTI in young children are _RENAL BLADDER ULTRACOUND (RBUS) and voiding cystourethrography (VCUG) 51. RBUS is an easily obtained, noninvasive test but can miss a small number of high-grade REFLUX cases 52. The benefits of RBUS (no radiation exposure, non-invasive, minimal discomfort for child andparents), however, outweigh the slight increase in specificity of VCUG

    6 53. A RENAL scan is useful for detecting renal scarring, a finding present after infection, but is not recommended for routine, initial evaluation of young child with their first febrile UTI.
