2 other interventions for hypoglycemia/unconscious
1. D50W: large bore IV|2. injectable glucagon IM if no IV access
201
4 measures to prevent hypoglycemia
1. eat!|2. take insulin regularly|3. know s/s of hypoglycemia|4. check BS regularly
202
DKA: tx (6)
1. find the cause|2. hourly labs and UO|3. IV insulin|4. ECG|5. ABGs|6. IVFs
203
2 labs you will want to draw hourly w/ DKA
- blood glucose||- potassium
204
IVFs for DKA
- 2 large bore IVs||- start w/ NS, then when BS gets down to 250-300, switch to D5W to prevent hypoglycemia||- at some point, HCP will want to add K+ to IVFs
205
hyperosmolar hyperglycemic nonketosis (HHNK)/hyperglycemic hyperosmolar state (HHS):|- which diabetes|- patho
- type 2||- looks like DKA, but no acidosis; BS > 600||- making just enough insulin so that they are not breaking down body fat
206
Kussmaul's in HHS?
no
207
3 other complications of diabetes
1. vascular problems|2. neuropathy|3. increased risk for infection
208
Vascular problems:|- patho|- 2 examples
- poor circulation everywhere d/t vessel damage d/t hypergylcemia -> sugar decreases size of vessel -> decreased blood flow||1. diabetic retinopathy|2. nephropathy
209
Neuropathy:|- 4 problems
1. sexual problems|2. foot/leg paresthesia/pain/numbness|3. neurogenic bladder|4. gastroparesis
210

permanent impotence/decreased sensation
211

212

- bladder does not empty properly||- bladder may empty spontaneously or may not empty at all
213
gastroparesis:|- patho|- risk for..
- stomach emptying is delayed||- increased risk of aspiration
