Trying to figure out labs

i think if i had more sleep this would not be so hard, but looking at labs and trying to make sence of abnormals, such as the ua lk esterase.

my pt is 2years old and has cystic fibrosis, i am trying to figure the order of nursing dx. as well. was going to group all my oxygen needs into dx(1) and then nutrition less than as dx (2). he is in for iv antibiotics. i was looking at his labs and trying to determine if i should have infection higher up.

1. ineffective airway, breathing, gas exchange r/t excess mucous secretions

(maslow's physiological need for oxygen; breathing)

2. imbalance nutrition

(maslow's physiological need for food and water)

3. risk for fluid volume imbalance r/t inadequate intake, iv fluids and tube feedings

(maslow's physiological need for fluid)

4.risk for decreased cardiac output r/t electrolyte imbalance

(maslow's physiological need for circulation)

5. risk for infection r/t decrease in ciliary action and increased pulmonary secretions (maslow's physiological need for physical body regulation)

your order of nursing diagnoses per maslow's hierarchy of needs should be:

  1. ineffective airway, breathing, gas exchange r/t excess mucous secretions (maslow's physiological need for oxygen; breathing)
    • i would just use impaired gas exchange r/t ventilation-perfusion imbalance and ineffective airway clearance r/t increased production of thick mucous. each diagnosis represents a different problem.

[*]imbalance nutrition

[*]risk for decreased cardiac output r/t electrolyte imbalance (maslow's physiological need for oxygen)

  • i don't see electrolyte imbalances causing a problem with the cardiac output. cardiac output consists of blood volume, heart rate and the force of the heart contraction. one of those 3 factors has to be altered to end up with a decreased cardiac output.

[*]risk for fluid volume imbalance r/t inadequate intake, iv fluids and tube feedings (maslow's physiological need for fluid)

  • correct title is risk for imbalanced fluid volume

[*]risk for infection r/t decrease in ciliary action and increased pulmonary secretions (maslow's physiological need for physical body regulation)

do you have a lab reference book? it would tell you the significance of abnormal (increased or decreased) lab results. i think your sequencing is fine except for the risk for decreased cardiac output which is a need for oxygen to the heart tissue and should be sequenced before the risk for imbalanced fluid volume. cf patients are always at a risk for infection, but i would not make it a priority diagnosis.

I do have a nursing lab book, but could not find anything on two interventions for LK Esterase with trace instead of having the normal negative for results. It does not even say what it is. I think it has to do with WBCs? I am suppose to have 1 intervention for every normal value and 2 interventions for every abnormal value. It is really hard to write intervention, when you are unsure of what you are looking at.

lk esterase (leukocyte esterase) is a substance produced by wbcs. its presence indicates that there are wbcs present. my copy of mosby's diagnostic and laboratory test reference says that if this is positive on a urinalysis it indicates a uti. it is measured by dipstick and some labs will not do a microscopic exam of the urine unless this test is positive--saves them the money of doing the microscopic exam, i guess. conditions where lk esterase is elevated in the urine are

  • bacterial, fungal or parasitic infections (especially uti)
  • calculus formation
  • glomerulonephritis
  • interstitial nephritis
  • tumors
