16
Q

Ventricular septal defect diagnosis

A

Chest x-ray shows normal or enlarged heart depending on the size of the defect

17
Q

Management for heart defects

A

Small defect – monitor Q6 months

Large defects – diuretics, ACE, Beta blockers, monitor intake and weight gain, teach s/s of HF, surgery to repair

18
Q

Left sided systolic heart failure

A

Heart cannot pump enough blood to supply the body – walls of the ventricle are thin and weak, unable to pump out meaning blood remains in the ventricle reducing output

19
Q

Causes of left sided systolic heart failure

A

a. structural defects of heart valves
b. disease of heart muscle (cardiomyopathy)
c. arrhythmias
d. heart attack

20
Q

Right sided systolic heart failure

A
  1. Walls of right ventricle are think and weak, unable to pump blood out, reduced cardiac output
  2. Commonly caused by left sided heart failure
21
Q

Risk factors for right sided systolic heart failure

A

a. HTN
b. CAD
c. Metabolic syndrome
d. DM
e. Structural heart abnormalities

22
Q

Symptoms of right sided systolic heart failure

A

a. Fatigue
b. Weakness
c. SOB
d. Swelling of lower limbs
e. Decreased alertness
f. Reduced ability to exercise

23
Q

Characteristics of heart murmur

A
  1. intensity - easily heard upon auscultation, soft, no thrill
  2. timing - systolic
  3. location - pulmonic area
  4. radiation - also heard in the left axilla
  5. quality - harsh crescendo-decrescendo
  6. duration - heard in mid systole
  7. pitch - medium sound
24
Q

Grades of heart Murmur

A

A grade 1 murmur is barely audible.

A grade 2 murmur is soft but easily audible.

A grade 3 murmur is louder but is not accompanied by a thrill.

A grade 4 murmur is loud with a palpable thrill.

A grade 5 murmur can be heard with the stethoscope partially off the chest and a thrill is palpable.

Finally, the grade 6 murmur is audible without a stethoscope.

All murmurs louder than grade 3 are pathological.

25
Q

Peripheral pulmonary stenosis murmur

A

usually heard at 1 to 2 months if the blood vessels to the lungs are small. This type of murmur resolves around 6 months of age. Soft blowing sound.

26
Q

Flow murmur

A

more common in 8- to 14-year-olds with thinner chest walls and is the sound of normal blood flow. Early to mid systolic, decreases with standing increases with CO. Soft blowing sound.

27
Q

Still’s murmur

A

most common between the ages of 2 and 6. This murmur has a musical characteristic and usually resolves by age 12. Short, vibratory, musical “twangy string” sound

28
Q

Venous hum

A

common between the ages of 2 and 8 and is the normal blood flow through the veins of the upper chest. It disappears with the turning of the head or jugular vein compression. All these murmur types are innocent.

29
Q

Qualities that may indicate pathological murmur

A
  1. Murmur in child with CHD
  2. Diastolic murmur
  3. Systolic murmur with thrill
  4. Pansystolic murmur
  5. Continuous murmur (not suppressed with pressing carotid)
  6. Systolic clicks
  7. Opening snaps
  8. Fixed splitting
  9. Accentuated s2
  10. Not positional
  11. Grade 4 or higher
  12. Harsh quality
30
Q

Hypertension in a child

A

Systolic, diastolic or both in the 95%+ percentile for age, sex and height on at least three separate occasions

Over age 13, 130/80 is considered hypertensive

31
Q

Things to assess when looking at HTN in a child

A
  1. Neonatal history
  2. Prior hospitalizations or trauma
  3. Diet and exercise
  4. Sleep history (OSA)
  5. Medications
  6. Chronic illnesses
  7. Headache, chest pain, dyspnea
  8. History for family – HTN, MI, stroke, DM, HLD
32
Q

Hypertension PE

A
  1. BMI, growth
  2. Edema, pallor, flushing
  3. Pulses upper and lower
  4. Elevated BP on 3+ occasions
33
Q

Diagnostics HTN in a child

A
  1. Search for secondary causes of HTN (renal function, plasma renin levels)
  2. CBC, ESR, CRP, UA & culture, electrolytes, BUN, creatinine, plasma renin
34
Q

Treating HTN in children

A
  1. BP check annually
  2. Two follow-up measurements within 1-2 months
  3. If overweight
    a. Caloric restriction
    b. Exercise 30-60 min per day w/relaxation techniques
    c. Avoid smoking, caffeine, drug and alcohol intake
  4. If HTN persistent refer to cardiology for treatment (ACE, ARB, beta blocker, CCB, diuretic)
35
Q

Sickle Cell Disease

A

Vaso-occlusion of blood vessels and periods of inadequate supply to the body’s tissues. Can impact all parts of the body

Caused by mutated gene that causes abnormal hemoglobin which are sickled and stick more easily to vessel walls causing interrupted blood and oxygen flow.

36
Q

S/S of sick cell disease

A
  1. Chronic pain
  2. Anemia
  3. Frequent infections
  4. Delay of growth and puberty
  5. Underweight
  6. Fatigue
  7. Swollen hands and feet
  8. Eye problems (blocked vessels in the retina)
37
Q

Education for patients with sickle cell disease

A
  1. Fluid intake – dehydration an trigger a crisis
  2. Avoid infection – good hand hygiene and avoiding sick people
  3. Activity – moderate activity with rest – hypoxia can trigger crisis
  4. Rest and adequate nutrition
  5. Maintain immunizations
  6. Wear medical identification
  7. Avoid the cold and elevation – they can be triggers
  8. Pain control with crisis – tyelnol, advil, narcotics
  9. Daily folic acid
  10. Penicillin V prophylaxis daily until age 5
38
Q

How is sickle cell anemia diagnosed

A

Diagnosis via isoelectric focusing (IEF), hemoglobin electrophoresis, or sickle solubility testing
