Lecture 6.2 - Endocrine Disorders Flashcards
What are the goals of treatment for type 1 and 2 DM?
Type 1: Integrate insulin with eating and exercise
Type 2: heart-healthy diet and moderate weight loss of 10% to 20%
-> Spaced meals can help
All should have 150 mins/week of moderate intensity aerobic physical activity + resistance training 3 days/week.
What is Kussmaul breathing?
Rapid deep breathing indicative of DKA
A diagnosis for DM involves which lab results?
A1C - >6.5
FPG - >7.0
OGTT - >11.1
What would a prediabetic fasting glucose test be? What about a 2-hour glucose tolerance test? A1C?
Fasting - 6.1-6.9 mmol/L
OGTT - 7.1-11 mmol/L
A1C of 6-6.4%
When a patient isn’t alert enough to swallow, how can we correct low blood sugar?
1 mg of glucagon IM/SC
In acute care, 20-59 mL of 50% dextrose can be given as an IV push
When is the peak BGL after a meal?
Two hours - so continue to monitor
What is the 15-15-15 rule?
If pt has low BGL, give 15-20 grams of simple carbohydrate (orange juice)
Wait 15 minutes, take BGL - if still low do another dose of sugar
Repeat until sugar is in normal range
Normal BGL range?
4-7 mmol/L
Irritability, diaphoresis, tremens, confusion, weakness, and hunger are associated with what?
Hypoglycemia
What kind of drug is glyburide?
Sulfonurea
–> Increases insulin production from pancreas
What kid of medication is metformin?
Biguanide
–> Reduce glucose production in liver + reduces insulin resistance
Side effects include bloating, nausea, cramping, and diarrhea
What is the onset of of glargine (Lantus)? Duration?
Onset 1-5 h, duration 24.
What is the onset of Determir (Lantus)? Duration?
Onset 3-4 hrs; duration 24 hrs
Before we treat DKA, what do we need to do?
Administer 2L of fluid and recheck blood sugar for accurate values.
–> Ringer’s preferred d/t Bicarb content
DKA is characterized by…
Hyperglycemia, ketosis, acidosis, and dehydration
A patient presents for vomiting, abdominal pain, a dry mouth and flushed face, dehydration, and increased pulse.
They have rapid, deep breathing.
What might be wrong?
DKA
What are the emergency management goals for DKA?
Airway –> O2
Correct fluid imbalance –> .45/.9 NaCl and slowly bring sugar down
Focus on potassium and bicarb replacement and anticipate that it will be low
Who is at risk for Hyperosmolar Hyperglycemic Syndrome?
Life-Threatening syndrome that often occurs in patients older than 60 with DM2.
What is exothalmus?
Bulging eyes associated with hyperthyroidism
A pt presents with weight loss, diarrhea, tachycardia and bruit over their throat. What else would you expect from this pt?
Hyperthyroidism
–> Enlarged thyroid, elevated t3 and t4 with low TSH
What treatment is recommended for hyperthyroidism?
Consider diet, drugs, and surgery
Diet: High protein and calorie, low caffeine and fiber
Drugs:
–> Propylthiouracil to block T3/4 synthesis
–> Iodine to destroy thyroid cells
Potential surgery to remove thyroid
What should you be aware of on a patient with thyroidectomy?
Check behind neck for drainage, position pt in high fowlers, and keep calcium gluconate at bedside
A patient presents with fatigue, brady, weight gain, constipation and periorbital edema and an intolerance to cold. What would you expect from this patient?
Hypothyroidism
–> Low T3/4 with rising TSH
What should you monitor when a patient is taking levothyroxine?
Hold if HR >100 BPM
