Cardiovascular, Cellular, and Hematologic Disorders –Discussion Part Three

This week’s graded topics relate to the following Course Outcomes (COs).

1 Analyze pathophysiologic mechanisms associated with selected disease states. (PO 1)

2 Differentiate the epidemiology, etiology, developmental considerations, pathogenesis, and clinical and laboratory manifestations of specific disease processes. (PO 1)

3 Examine the way in which homeostatic, adaptive, and compensatory physiological mechanisms can be supported and/or altered through specific therapeutic interventions. (PO 1, 7)

4 Distinguish risk factors associated with selected disease states. (PO 1)

5 Describe outcomes of disruptive or alterations in specific physiologic processes. (PO 1)

6 Distinguish risk factors associated with selected disease states. (PO 1)

7 Explore age-specific and developmental alterations in physiologic and disease states. (PO 1, 4)

Cardiovascular, Cellular, and Hematologic Disorders –Discussion Part Three

A new patient is brought into the office for their annual evaluation. The child is a 6-year-old and appears a bit small for their age but not so small that any alarm bells are set off. The vitals are: P = 116, R = 22, T = 98.6 , BP = 110/50. (The normal vitals in a 6-year-old are P = 75 – 120, R = 16 – 22, T = 98.6 , BP = (85-115)/(48-64). Examination of the lungs is normal, HEENT is normal, as is the abdominal exam. The heart however, seems laterally displaced and there appears to be only a continuous murmur which can be described as crescendo/decrescendo systolic murmur that extends into diastole. Because, you were trained at Chamberlain College of Nursing you immediately know that this is probably a patent ductus arteriosus.

  • Explain the murmur from a mechanistic view of the hearts physiological functioning?
  • What is the epidemiology of a patent ductus arteriosus?
  • How is a patent ductus arteriosus treated?
