Nurses understand that TSH released from the pituitary gland stimulates T3 & T4 to be produced by the thyroid (negative feedback loop). When levels of T3 & T4 aren't high enough, the pituitary gland never gets the signal to stop production of TSH. If the TSH continues to be produced, the thyroid gland can enlarge. This is one of the causes of a __________.

This long acting insulin is typically given at night, and works over a period of 24 hours.
What is Lantus?
The normal blood glucose range is 70-100 mg/dL. Patients who are close to 70 mg/dL or lower, may present with symptoms of hypoglycemia. If they are unable to take medications by mouth and they have no IV line, this medication may be used to increase their blood glucose. This medication can be given IM.
What is glucagon?
True or False?
Patients who are on thyroid replacement medication are typically on it for life.
TRUE!
Lifelong replacement is important even after improvement. Do not ever discontinue thyroid replacement medications without talking with the provider.

ATI PN Pharm Ch. 35 p. 303
Of the following laboratory values reported by the unlicensed assistive personnel (UAP),which one indicates an urgent need for the nurse to assess the patient?
a. Bedtime glucose of 140 mg/dL
b. Noon blood glucose of 52 mg/dL
c. Fasting blood glucose of 130 mg/dL
d. 2-hr postprandial glucose of 220 mg/dL
C. Noon blood glucose of 52 mg/dL
Rationale:
The nurse should assess the patient with a blood glucose level of 52 mg/dL for symptoms of hypoglycemia and initiate the hypoglycemia protocol. The other values are within an acceptable range or not immediately dangerous for a patient with diabetes.
If the patient takes this medication and is scheduled for a CT contrast with injected dye, the patient should hold off on this medication for the next 48 hours.

1. Decreased TSH levels. TSH decreases as the negative feedback loop is closed when T4 rises to signal it to turn off.
2. T4 levels in expected range.
3. Symptoms of hypothyroidism are resolved.
When Gland Number One secretes a hormone to stimulate target cells in Gland Number Two to release another hormone, and then Gland Number One stops secreting based on the levels secreted by Gland Number Two, this is known as ____________.
What is a negative feedback loop?
Step 1: Gland A secretes a hormone which stimulates Gland B to secrete a different hormone.
Step 2: Gland B secretes. The blood level of the hormone secreted by Gland B rises.
Step 3: This rise signals Gland A to stop secreting.

A hospitalized patient who is diabetic received 38 units of NPH insulin at 7:00 AM. At 1:00 PM, the patient has been away from the nursing unit for 2 hours, missing the lunch delivery while awaiting a chest x-ray which has been delayed. What is the best action by the nurse to prevent hypoglycemia?
a. Plan to discontinue the evening dose of insulin.
b. Save the lunch tray for the patient's return.
c. Call the Radiology department, and ask that if the testing needs to be further delayed, that the patient be sent back to eat lunch.
d. Send a glass of orange juice to the patient in the diagnostic testing area.
c. Call the Radiology department, and ask that if the testing needs to be further delayed, that the patient be sent back to eat lunch.
Rationale:
Consistency for mealtimes assists with regulation of blood glucose, so the best option is for the patient to have lunch at the usual time. Waiting to eat until after the procedure is likely to cause hypoglycemia. Holding the insulin dose later will not prevent hypoglycemia from the peak of the NPH dose. A glass of juice may keep the patient from becoming hypoglycemic but will cause a rapid rise in blood glucose because of the rapid absorption of the simple carbohydrate in these items, and who will deliver the juice??
These medications bind to the GLP-1 receptor reducing appetite, stimulating insulin release, and preventing glucagon release. What is this class of medication?
