how would the following diagnostics be affected by hypovolemia
BUN
hct
K,
Na
- BUN can be elevated because of dehydration or decreased renal perfusion and function.
- Inc Hct.
- K and Na levels may be reduced or elevated.
- Hypokalmeia occurs with GI and renal losses
- Hyperkalmeia- adrenal insufficiency
- Hyponatremia –inc thirst and ADH release
- Hypernatremia – inc insensible losses and diabetes insipidus
- Urine specific gravity is inc in relation to the kidneys attempt to conserve water
if pt is hypovolemic what type of solution will be hung iso/hypo/hyper
when is this necessary
try to use oral rehydration if possible
isotonic initially then hypotonic electrolyte soln to promote renal excretion of metb waste
how are bun and hct affected by hypervolemia
what diagnostic can tell you about severe hypervolemia
both dec d/t plasma dilution
chest x ray might show pulm congestion
what is azotemia
• Azotemia (increased nitrogen levels in the blood) can occur when urea and creatinine are not excreted due to decreased perfusion by the kidneys and decreased excretion of wastes. High uric acid levels (hyperuricemia) can also occur from increased reabsorption and decreased excretion of uric acid by the kidneys.
how might you tell hypervolemic pt to alter their diet
dec table salt
should pt mobilize or rest often if edematous
• Regular bed rest may be beneficial because bed rest favoursdiuresis of edema fluid.because of diminished venous pooling and increase in circulating blood volume.
routes of intraspinal analgesia delivery
• Intraspinal analgesia can be administered through a 1) bolus 2) continuous infusion (pump can be external or surgically implanted) 3) continuous plus intermittent bolus (often patient-controlled episdural analgesia PCEA
least desirable route for opioid delivery
IM d/t variable absorption and pain with admin•
advantage of transnasal route for opioid delivery
Transnasal: rapid action of the medication because of direct absorption through the vascular nasal mucosa
how do crystalloids work
by osmosis
indications for crystalloid
advantage over colloid or blood product
• Replace fluid loss and promote urinary flow. Much less expensive than colloids and blood products.
which is better at expanding plasma volume colloid or crystalloid
which stays in vascular space longer
colloids
colloids
is colloid or crystalloid more likely to cause edema and why
crystalloids because you need a much larger volume to achieve the effect
post op recovery room how often are your checks
Q15 min skilled focused assessments (head to toe w focus on ABCDE)—i dont have my epi check sheet anymore
what % of o adults get postop delirium
lots. in class she said up to 50
what assessments should you do for resp system
- RR, look in their mouth, listen to resp sounds (may sound like gargling), may need to put hand in front of nose to feel breath
- look in their mouth, RR etc
- for swelling, ask pt how their throat feels
look for laryngeal edema
nursing dx r/t airway (not breathing)
- Potential airway obstruction d/t hypopharyngeal obstruction (floppy airway) r/t effects of anaesthesia.
- Potential airway obstruction d/t presence of vomitus in the airway. (have emesis basin and suction ready)
- Potential airway obstruction d/t allergic reaction to medications (analgesia, antibiotics)
- Sore throat d/t insertion of endotracheal tube and NPO status for many hours.
how are most anesthetics and how does this affect nursing care
- Sometimes people after anesthetics will have lg pauses between inhalation/exhalation. Look at 02 sats, LOC (older adults and kids can be hyperactive or agitated), RR, listen to lung sounds, most anesthetics are excreted by the body by breathing (ask the pt to take deep breaths while listening)
- DB&C and incentive spirometry.
nursing dx r/t breathing
Hypoventilation (decreased respiratory rate) d/t affects of opioids and anesthetics
Decreased oxygenation due to atelectasis (collapse of the alveoli)
Retention of anaesthetics r/t hypoventilation
why does pt have risk for DVT after sx
Risk for DVT, embolus d/t immobility for extended period during surgery, increased clotting response d/t surgical process, reduction in anticoagulant medications in preparation for surgery.
During sx we may have very thick blood, stress causes inc in clotting factors, venous stasis
