A client is admitted with hyperosmolar hyperglycemic state​ (HHS) and a blood glucose level of 550​ mg/dL. Which intervention should the nurse expect to include in the plan of​ care? (Select all that​ apply.) A. Give normal saline intravenously. B. Obtain blood for hemoglobin A1C. C. Assess level of orientation. D. Provide education about type 2 diabetes mellitus. E.

Potassium is​ depleted, so it must not only be​ monitored, but also replaced. This client is acutely​ ill, so the hemoglobin A1C should be​ reviewed, but it is not a priority. Education should wait until the​ client's blood glucose level is stabilized and the client is alert enough to be receptive to the teaching.

Metformin (Glucophage)

Decreases rate of hepatic glucose production & augments glucose uptake by tissue --IV contrast containing iodine can be harmful with metformin- risk of kidney injury/ lactic acidosis --to reduce kidney injury, discontinue meds a day before surgery --can be resumed 48 post op if kidneys are normal --do not with chronic drinkers --take with food

Nursing Evaluation for DM

Expected outcomes --pt has age appropriate understanding of self management --pt's skin integrity stays intact --pt remains free from infection --pt remains free from injury Nonexpected outcomes --assess diet and medication adherence --develop plan of care that addresses nonadherence

Older adult considerations

Falls, polypharmacy, functional disabilities, cognition issues, depression, incontinence, increased risk for hypo/hyperglycemia set goals with older patients

Clinical manifestations of diabetes

Fatigue, extreme thirst, frequent urination, extreme hunger, weight loss, infection, slow wound healing, blurry vision *lose weight because insufficient glucose in cells for energy so body starts burning fat and muscle

Nursing Planning for DM

Goals --teach how to administer meds and side effects --teach meal planning compliant with ADA --teach about foot inspection and care --teach proper monitoring for blood sugar levels --teach about reducing risk for infection

Examples of NURSING diagnosis

Learning Needs, Risk for Impaired Skin integrity, Risk for Infection, Risk for Unstable blood glucose levels, Risk for

Nursing assessment for DM

Outward S/S Medications Review glucose log Diet (especially carbs) Weight gain/loss exercise urine output VS Microvascular/macrovascular complications skin assessment

Lispro (Humalog)

Rapid-acting insulin. Onset: 15 minutes. Peak: 1-1.5 hours Duration: 3-4 hours

microvessel issues

blurred vision, loss of site, nerve damage, kidney disease

Macrovessel issues

cardiovascular issues, heart disease, stroke, poor blood circulation

A1C test

for diabetes by checking sugar on red blood cells to get an average glucose % level over 3 months

diabetes mellitus

inability of islet cells to make insulin or produce enough to control blood glucose levels

hypoglycemic agents caused by

increased insulin secretion liver prevents glycogen to glucose increased uptake of glucose by muscle/fat in arms/legs instead of trunk blocked absorption of carbs in intestines nursing intervention: monitor for reactions administer with meals

NPH (Novolin N)

intermediate acting insulin Onset: 2 hours Peak: 6-8 hours Duration: 12-16 hours

Lantus (glargine)

long acting insulin Onset: 2 hours Peak: 16-20 hours Duration: 24 +

type 2 diabetes mellitus

modifiable weight sedentary lifestyle family history race/ethnicity advancing age metabolic syndrome (HT, increase in triglycerides, etc)

type 1 diabetes mellitus

non modifiable genetic autoimmune environmental factors (virus, illness)

alpha cells

produce glucagon- promotes liver to release glucos

Do NOT give metformin if......

pt has kidney, liver, or heart failure - lactic acidosis is a rare complication

What is the only insulin given IV?

regular insulin

Peripheral neurovascular dsyfunction

risk of disruption in circulation, feeling, or motion in limb - very common with T2D

Regular Novolin R

short acting insulin Onset: 0.5-1 hour Peak: 2-3 hours Duration: 4-6 hours

sick day management

sick/surgery - blood glucose increases even if food decreases -monitor blood glucose every four hours -test urine for ketones -keep taking meds -8-12 oz water each hour -substitute easily digested liquids or foods -Call HCP if unable to eat for 24 hours and diarrhea for more than 6 hours

Nursing Implementation for DM

teach to recognize/seek care for hypERglycemia ex. -extreme hyperglycemia -increased urination -thirst -dehydration -hypotension -seizures -decreased LOC *SMBG by pt not using insulin should help reach glucose goals

hyperosmolar hyperglycemic state​ (HHS)

your body is trying to rid excess blood sugar to urine include signs of dehydration, weakness, leg cramps, vision problems, and an altered level of consciousness. A client in HHS would have an increase in urinary output due to the hyperosmolarity of the blood
