kids < 2yo
Crying = #1 trigger
Acquired heart dz: Acute rheumatic fever - CORRECT ANSWER: An autoimmune
response to a previous group A strep infxn (pharyngitis). Often develops 2-4 wks after
strep/URI infxn.
Assessment:
- previous strep infxn
DX: based on JONES criteria (must have 2 major, or 1 major and 2 minor criteria)
- MAJOR:
- joints (polyarthritis)
- carditis
- nodules (lymphadenopathy)
- erythema marginatum
- sydenhams chorea (involuntary jerking movements)
- MINOR:
- fever
- ESR elevated
- long PR interval
- arthralgia
,Nursing mgmt:
- Abx (10d of penicillin)
- corticosteroids
- REST!
- pain mgmt
- if valvular complications involved (mitral regurg. or aortic stenosis)
- prophylactic Abx lifelong before invasive procedures
- if no valvular complications involved
- prophylactic Abx for 5 yrs, or until 21 yo, before invasive
procedures.
Acquired heart dz: Heart Failure - CORRECT ANSWER: S/S:
- sweating
- swelling of hands, feet, eyes
- breathing problems
- poor growth
- cyanosis
- tachycardia
- poor feeding
Nursing mgmt:
- promote oxygenation
- promote nutrition (small more frequent meals)
- promote rest
- support heart fxn (daily wt, I&O, meds, assessments)
- promote tissue perfusion w/ positioning
- r/f infxn :infective endocarditis
,- must receive prophylactic Abx before invasive procedure
Medications:
1. DIGOXIN
- increases contraction force, decreases HR
** Hold for older kids HR < 60, Young kids HR < 70, infants HR < 90 **
- given BID 12 hr apart ( 1 hr before food, or 2 hr after food)
- if missed dose > 4 hr or child vomits, wait until next dose. If 2 doses missed, contact
MD
** Toxicity s/s: N/V, decreased appetite, bradycardia, drowsiness, lethargy
2. FUROSEMIDE (Lasix)
- r/f hypokalemia (increases r/f digoxin toxicity)
Acquired heart dz: HTN - CORRECT ANSWER: Screening starts @ 3yo
- BP norms based on age, gender, and height.
** Needs 3 separate high BP reads before can officially dx w/ HTN
Kids 1-13yo
- Normal BP < 90th percentile
- Elevated BP is > 90th but < 95th percentiles
Kids > 13 yo, follow adult BP guidelines
Primary vs Secondary HTN
- HTN > 95th percentile
Manage with diet and exercise, meds only if diet/exercise aren't effective
, Acquired heart dz: Hyperlipidemia (HLD) - CORRECT ANSWER: Assessment:
- Starts @ 24 mo for infants w/ RFs present (FHx of HLD or CVD, early unexplained
death of relative, or no FHx/Hx available)
- Universal screening begins @ 9-11 yo
- 2nd screening @ 18-20 yo
Elevated levels:
Total chol > 200
LDL >/= 130
Mgmt and edu:
- manage with diet and exercise
- track BMI
- 60 min/day exercise
- meds PRN if diet and exercise aren't working
Acquired heart dz: Kawasaki - CORRECT ANSWER: ** LEADING CAUSE OF
ACQUIRED HEART DZ IN KIDS**
Acute systemic vasculitis, unknown cause
DX: based on clinical assessment
- fever of at least 5 days
AND 4 of the following...
- bilateral conjunctivitis (eye infxn)
- changes to lips or oral mucosa (dry chapped lips, strawberry tongue)
- changes to extremities (reddened palms/soles, edema, desquamation/peeling)
- polymorphous rash
- cervical lymphadenopathy
