Q

Why is it important to assess the client’s coping skills for Endocrine dysfunction?

A

Because a lot of hormonal changes make patients feel like they’re not themselves (moody, irritable, angry). As nurses we must evaluate how the patient feels about these behavioral changes and determine if a referral to social service may be required.

Respiratory distress
28
Identify 3 interventions for Disturbed Thought Processes
Assess lethargy, drowsiness, memory deficit, poor attention span, and difficulty communicating (these problems should decrease with thyroid hormone treatment), Provide a safe environment, Provide family teaching.
29
This life- threatening condition results from extreme or prolonged HYPOTHYROIDISM. It is characterized by a severe hypometabolic state: coma, respiratory failure, hypotension, hyponatremia, hypothermia, hypoglycemia, bradycardia
Myxedema Coma
30

Methimazole (Tapazole) and Propylthiouracil (PTU, Propacil)
31
In addition to Antithyroid medications, Iodine is another effective treatment option for HYPOTHYROIDISM?
False, it's effective in managing HYPERTHYROIDISM.
32
True or False. Levothyroxine (Synthroid, Levothroid) is an example of a Thyroid Replacement medication available for patients with HYPOTHYROIDISM?
TRUE
33
True or False, Thyroid Replacement medications can cause an arrhythmia, angina, and increased oxygen demand?
TRUE
34
The biggest problems associated with Myxedema Coma are?
Decreased cardiac output, decreased perfusion, less stimulus for breathing, respiratory failure.
35
Emergency care related to Myxedema Coma includes?
Giving thyroid replacement and doing supportive interventions, such as ventilation (CiPap, BiPap) and monitoring for low calcium.
36
What is the ONE thing parathyroid glands do?
Their major function is to maintain normal serum calcium levels by secreting parathyroid hormone (PTH), which increases bone reabsorption of calcium. (Calcium and phosphate balance).
37
Hyperparathyroidism
An increase in PTH, which leads to hypercalcemia, hypophosphatemia, bone damage, and renal damage.
38
Hypoparathyroidism
A decrease in PTH, which leads to hypocalcemia, hyperphosphatemia, hyperreflexia, and an altered sensorium. (Decreased function of the parathyroid gland).
39
True or False. Parathyroids are often removed?
False. They are rarely removed and often transplanted into the arm to keep PTH, PTH keeps calcium up. Calcium is harder to regulate without it.

42
Postoperative care following a parathyroidectomy includes?
Observe for respiratory distress, Keep emergency equipment at bedside (Ca injection) because a hypocalcemic crisis can occur, Recurrent laryngeal nerve damage can occur.
43
Name the top 3 concerns of a thyroidectomy and parathyroidectomy
Bleeding, laryngeal edema, hormone fluctuations. The main problems are the surgical site and inability to maintain serum calcium.
44
Nursing interventions for Hypoparathyroidism include?
Correcting hypocalcemia, vitamin D deficiency, and hypomagnesemia
45
Iatrogenic vs. Idiopathic Hypoparathyroidism
Iatrogenic means it was caused by the treatment, or by the doctor. So iatrogenic hyperthyroidism means the hyperthyroidism was caused by taking too much thyroid hormone. Idiopathic hypoparathyroidism may be inherited or acquired later in life.
46
Name 2 examples of Posterior Pituitary Disorders
Diabetes Insipidus (DI) and Syndrome of Inappropriate Antidiuretic Hormone (SIADH)
47
ADH
Also known as Vasopressin, is a hormone secreted from the posterior pituitary gland. It's main purpose is to control serum osmolarity and water balance.
48
Diabetes Insipidus (DI)
Results from ADH insufficiency (too little), leading to excess fluid excretion (polyuria, up to 12L a day). When the post. pituitary does not produce enough or any ADH, patients cannot reabsorb water.
49
SIADH
Results from excessive excretion of ADH (too much ADH) and excessive water retention.
50
What is the cardinal symptom of DI?
Polyuria
51
What causes DI?
Head trauma with damage to the pituitary, subdural hematomas, pituitary tumors
52
What will happen to a patient experiencing excess fluid excretion as a result of DI?
The patient will become hypernatremic
53
What causes SIADH?
This condition is often associated with the ectopic production of ADH by malignant tumors. For example, lung cancers can mimic and create a clone of ADH. So it's not the pituitary that producing too much ADH, it's the cancer cells.
54
True or False. Hypernatremia is the primary problem of SIADH?
False, Hyponatremia is the primary problem because the Na becomes too diluted during fluid overload.
55
If a patient's urine output is greater than 400ml an hour, you should suspect SIADH? T or F?
False, you should worry about DI.
56
Why do patients with DI need fluid replacement?
Because all of their symptoms are being caused by high Na levels.
57
Prevents or controls thirst and frequent urination caused by diabetes insipidus and certain brain injuries.
DDAVP, replaces vasopressin
58
Treating DI includes?
Hormone and fluid replacement (vasopressin)
59
Treating SIADH includes administering diuretics and restricting fluids. T or F?
TRUE, fluid intake should be restricted so that further dilution of Na won't continue
60
Identify 3 Nursing Management interventions for ADH disorders
Monitor: Fluid balance, electrolyte balance, cardiac conduction, cardiac output an d perfusion, mental and neuro status.
61
Diabetes Mellitus (DM)
Occurs when the pancreas fails to secrete an adequate amount of insulin. Most common chronic disorder of the endocrine system.
62

Insulin dependent
63
Type II (DM)
Patients still produce some insulin, but it's not as effective. May require oral hypoglycemics, but can be managed with diet and exercise.
64
True or False. Gestational, stress, and steroids are all examples of variant types of DM?
TRUE
65
Cortisol
Stress response causes increased levels of cortisol in your body, cortisol increased blood glucose and blocks insulin.
66
Polyuria, polydipsia, and polyphagia are common clinical manifestations of Type II Diabetes?
False, only polyuria and polydipsia (thirst) are common symptoms. Polyphagia (hungry) is only seen in Type I diabetics.
67
Why do Type I patients get hungry?
Because of a lack of insulin, their body must use and breakdown proteins and fats for energy. This use of fats results in ketones. As ketones build up, acidosis occurs. This breakdown of nutritional stores leads to excessive hunger.
68
What is the only difference between Type I and Type II?
Type II have enough insulin to prevent the breakdown of fats and muscles for energy.
69
Diabetic Ketoacidosis (DKA)
Results in severe metabolic, fluid, and electrolyte disturbances, and is a life threatening condition of hyperglycemia and metabolic acidosis, requiring immediate action.
70
Abdominal pain, weakness, fatigue, nausea, vomiting, metabolic acidosis, fruity breath odor, Kussmaul respirations, decreased LOC, coma, and death if untreated are all examples of what disorder?
DKA
71
How will you know your patient is developing DKA?

TRUE
77
What is the desired amount for HgAic (glycosolated Hgb)?
4 to 6 percent

79
True or False, when physically examining patients for DM, it's important to assess for bruises and peripheral neuropathy
TRUE, however these are chronic complications that can take 10 to 20 years to develop.
80
Urine tests are used to test for which of the following. Ketones, Renal Function, or Glucose?
All of the above, not done very often but patients are now being encouraged to check their own urine at home.
81
Hyperglycemic Hyperosmolar Nonketotic Syndrome (HHNS) vs. DKA
Symptoms are the same except patients with HHNS won't have an acetone odor because they're not breaking down protein to have ketones. They'll still be lethargic, have dry skin, and blood glucose levels between 800 and 1000.
