R Insulin
1. alcohol and garlic make glucose decrease 2. do not store in sunlight 3. monitor K
Regulation of Corticosteroids
1. cortisol level rises 2. negative feedback given ti hypothalamus and pituitary 3 corticosteroid release shut off (negative feedback)
DM Pharmacotherapy
1. goal is to keep blood glucose within normal range 2. insulin admin must be carefully planned w/ meal and lyfestyle 3. insulin secretion varies based on ADLs
Exenatide (Byetta)
1. prescribed twice a day to increase secretion of insulin 2. AE: nausea, vomiting, & diarrhea
Cosyntropin (cortrosyn)
1. resembles ACTH 2. used to diagnose cause of Adrenocortical insufficiency
propylthiouracil (PTU)
1. treats hyperthyroididms 2. lowered hr, less anxiety, and better sleep 3. report fever, rashes, sore throat, chills, malaise, & weakness
Aldosterone
regulate plasma volume by promoting na absorption and K secretion in renal tubes
Which of the following assessment findings would cause the nurse to withhold the patient's regularly scheduled dose of levothyroxine (Synthroid)?
A heart rate of 110 beats/minute
negative feedback
A hormone causes an action at its target cell or tissue; output signal has reversed the condition of the original stimulus
Desmopression (DDAVP) intranasal
spray high in the nostril
Sulfinylureas
stimulate the release of insulin from pancreatic cells (avoid Alcohol) [1st gen: "Mide" 2nd gen: "ride" except glipizide]
Meglitinides
stimulate the release of insulin from pancreatic islet like sulfonylureas ["inide"]
A patient receives NPH and regular insulin every morning. The nurse is verifying that the patient understands that there are two different peak times to be aware of for this insulin regimen. Why is this an important concept for the nurse to stress?
The risk for hypoglycemia is greatest around the peak of insulin activity
GH
Growth Hormone
Hyper- aldosterone
HTN and hypOkalemia
The nurse is assisting a patient with chronic adrenal insufficiency to plan for medication consistency while on a family vacation trip. He is taking hydrocortisone (Cortef) and fludrocortisones (Florinef) as replacement therapy. What essential detail does this patient need to remember to do?
Carry an oral and injectable form of both drugs with him on his trip
The patient with type 2 diabetes has been nothing by mouth (NPO) since midnight for surgery in the morning. He has been on a combination of oral type 2 antidiabetic drugs. What would be the best action for the nurse to take concerning the administration of his medications?
Contact the health care provider for further orders
Primary Adrenalcortical insufficiency
Corticosteroids fail to rise after injection
How to treat Adrenalcortical insufficiency
IV therapy of hydrocortisone (the symptoms of Adren. insufficiency can cause shock)
MSH-IH
Melanocyte-stimulating hormone inhibiting hormone
Biguanide
Metformin; reduces glucose by decreasing hepatic production of glucose and reducing insulin resistance
Miscellaneous DM2 drugs
bromocriptin & colesevelam: acts on CNS to increase dopamine "liflozin" : inhibiting SGLT in kidney allowing more glucose to be secreted through urine
A 63-year-old patient with type 2 diabetes is admitted to the nursing unit with an infected foot ulcer. Despite previous good control on glyburide (Micronase), his blood glucose has been elevated the past several days and he requires sliding-scale insulin. What is the most likely reason for the elevated glucose levels?
It is a temporary condition related to the stress response with increased glucose release
The patient is scheduled to receive 5 units of Humalog and 25 units of NHP (Isophane) insulin prior to breakfast. Which nursing intervention is most appropriate for this patient?
Make sure the patient's breakfast is available to eat before administering the insulin
