A patient has a total serum calcium level of 3mg/dL. If this finding reflects hypoparathyroidism, the nurse would expect further diagnostic testing to reveal a. decreased in PTH b. increased serum ACTH c. increased serum glucose d. decreased serum cortisol levels
a. decreased in PTH Rationale: Normal serum calcium level is 8.6 to 10.2 mg/dL. A low serum calcium level is found in hypoparathyroidism, and the serum parathyroid hormone (PTH) level is decreased.
A 72 year old woman is diagnosed with diabetes. The nurse recognizes that management of diabetes in the older adult a. does not require as tight glucose control as in younger diabetics. b. is usually not treated unless the patient becomes severely hyperglycemic. c. does not include treatment with insulin because of limited dexterity and vision. d. usually requires that a younger family member be responsible for care of the patient.
a. does not require as tight glucose control as in younger diabetics. Rationale: Because the clinical manifestations of long-term complications of diabetes take 10 to 20 years to develop, and because tight glucose control in the older patient is associated with an increased frequency of hypoglycemia, the goals for glycemic control are not as rigid as in the younger population.
A patient has a serum sodium level of 152 mEq/L. The normal hormonal response to this situation is a. release of ADH b. release of renin c. secretion of aldosterone d. secretion of corticotropin-releasing hormone
a. release of ADH Rationale: The most important stimulus of antidiuretic hormone (ADH) secretion is plasma osmolality, which is a measure of solute concentration of circulating blood. Plasma osmolality increases when there is a decrease in extracellular fluid or an increase in solute concentration. The increased plasma osmolality activates osmoreceptors, which are extremely sensitive, specialized neurons in the hypothalamus. These activated osmoreceptors stimulate ADH release. When ADH is released, the renal tubules reabsorb water, creating urine that is more concentrated.
Endocrine disorders often go unrecognized int he older adult becuase a. symptoms are often attributed to aging b. older adults rarely have identifiable symptoms. c. endocrine disorders are relatively rare in the older adult d. older adults usually have subclinical endocrine disorders that minimize symptoms
a. symptoms are often attributed to aging Rationale: Assessment of the effects of aging on the endocrine system is difficult because the subtle changes of aging often mimic manifestations of endocrine disorders.

b. excessive facial hair on women e. hyperpigmented coloration in lower legs Rationale: Hirsutism (i.e., excessive facial hair on women) may indicate Cushing syndrome or prolactinoma, a pituitary tumor. Hyperpigmentation (i.e., darkening of the skin, particularly in creases and skin folds) may indicate Addison's disease caused by increased secretion of melanocyte-stimulating hormone or indicate acanthosis nigricans.
A characteristic common to all hormones is that they: a. circulate in the blood bound to plasma proteins b. influence cellular activity of specific target hormones c. accelerate the metabolic processes of all body cells d. enter a cell to alter the cell's metabolism or gene expression
b. influence cellular activity of specific target hormones Rationale: A hormone is a chemical substance synthesized and secreted by a specific organ or tissue.

Goals of nutritional therapy for the patient with ape 2 diabetes include maintenance of a. ideal body weight b. normal serum glucose and lipid levels c. a special diabetic diet using dietetic foods. d. Five small meals per day with a bedtime snack
b. normal serum glucose and lipid levels Rationale: Maintenance of as near-normal blood glucose levels as possible and achievement of optimal serum lipid levels with dietary modifications are believed to be the most important factors in preventing both short and long term complications of diabetes.
Priority Decision: The nurse is assessing a newly admitted diabetic patient. Which of these observations should be addressed as a priority by the nurse? a. Bilateral numbness of both hands. b. Stage II pressure ulcer on the right heel c. Rapid respirations with deep inspiration d. Areas of lumps an dents on the abdomen
c. Rapid respirations with deep inspirations Rationale: Rapid deep respirations are symptoms of diabetic ketoacidosis (DKA). Stage II ulcers and bilateral numbness are chronic complications of diabetes. The lumps and dents on the abdomen indicate a need to teach the patient about site rotation.
All cells in the body are believed to to have intracellular receptors for a. insulin b. glucagon c. growth hormone d. thyroid hormone
d. thyroid hormone Rationale: There are two types of receptors: those that are within the cell (e.g., steroid and thyroid hormone receptors) and those that are on the cell membrane (e.g., protein-type hormone receptors). Thyroid hormone receptors are located inside the cell. Because these hormones are lipid soluble, they pass through the target cell membrane by passive diffusion and bind to receptor sites located in the cytoplasm or nucleus of the target cell. Intracellular hormone-receptor complexes bind to specific sites on deoxyribonucleic acid (DNA) to stimulate or inhibit the synthesis of messenger ribonucleic acid (mRNA). When new mRNA is synthesized, it migrates to the cytoplasm, where it instructs the synthesis of new protein. These new proteins produce specific effects in the target cell.
Diagnostic testing in the patient with Graves' disease will reveal an
decreased TSH level.
When replacement therapy is started for a patient with long-standing hypothyroidism, its is most important for the nurse to monitor the patient for

How are hormones transported?
in the blood to other sites in the body where their actions are exerted.
An appropriate nursing intervention for the patient with hyperparathyroidism is to
increase fluid intake to 3000 to 4000 mL daily. Rationale: A high fluid intake is indicated in hyperparathyroidism to dilute the hypercalcemia and flush the kidneys so that calcium stone formation is reduced.
Clinical manifestations of hyperthyroidism occur as a result of
increased metabolic rate and tissue sensitivity to the sympathetic nervous system.

meal planning technique that individuals with diabetes use to keep track of the amount of carbohydrates they eat with each meal and per day. With this method they set a limit for their maximum amount. The amount of total carbohydrates per day depends on age, weight, activity level, and medications that they take. - Instruct patient on the foods that contain carbohydrates and the appropriate serving size. Each serving of carbohydrates is 15g. They usually start with 45 to 60 g of carbohydrate at a meal.

In caring for the patient with a goiter and possible hypothyroidism, what is the most appropriate way to complete a physical assessment, and what are some interventions that the nurse anticipates?
Careful assessment may reveal early and subtle changes that indicate dysfunction. Your assessment of the patient who is suspected of having hypothyroidism should include questions about weight gain, mental changes, fatigue, slowed and slurred speech, cold intolerance, skin changes such as increased dryness or thickening, constipation, and dyspnea. Question the patient about the recent introduction of iodine containing medications. Assess the patient for bradycardia; distended abdomen; dry thick, cold skin; thick, brittle nails; paresthesias; and muscular aches and pains. p. 1271 Acute Interventions: - Most individuals with hypothyroidism are treated on an outpatient basis. The patine who develops myxedema coma requires acute nursing care, often in an intensive care setting. Mechanical respiratory support and cardiac monitoring are frequently necessary. - Administer thyroid hormone replacement therapy and all other medications intravenously because paralytic ileum may be present in myxedema coma. Monitor the core temperature because hypothermia often occurs in myxedema coma. - Monitor the patient's progress by assessing vital signs, body weight, fluid intake and output, and visible edema. Cardiac assessment is especially important because the cardiovascular response to the hormone determines the medication regimen. Note energy level and mental alertness. These should increase within 2 to 14 days and continue to rise steadily to normal levels. p. 1271

DO - Monitor your blood glucose at home and record results in a log. - Take your insulin or OA as prescribed. - Obtain A1C blood test every 3-6 months as an indicator of your long-term blood glucose control. - Know the symptoms of a hypoglycemia and hyperglycemia - carry some form of glucose at all times so you can treat hypoglycemia quickly - Instruct family members in the use of glucagon administration in the case of emergencies due to hypoglycemia. - Learn how exercise and food affect your blood glucose levels. - Begin an exercise program after approval form health care provider. - Have an individualized meal plan created by a dietitian. - Follow your diet, eating regular meals at regular times. - Choose foods low in saturated and trans fat. - Learn your cholesterol level. - Obtain an annual eye examination by an ophthalmologist. - Obtain annual urine testing for protein. - Examine your feet at home. - Wear comfortable, well-fitting shoes to help prevent foot injury. Brak in new shoes gradually. - Always care identification that says you have diabetes. - Have other medical problems treated, especially high blood pressure and high cholesterol. - Quit cigarette smoking. DO NOT - skip doses of your insulin, especially when you are sick - Run out of insulin - Ignore the symptoms of hypoglycemia and hyperglycemia. - Forget that exercise will lower your blood glucose level. - Drink excessive amounts of alcohol because this may lead to unpredictable low blood glucose reactions. - Enroll in a fad diet. - Drink regular soda or lots of fruit juice. - Smoke cigarettes or use nicotine products. - Apply hot or cold directly to your feet. - Go barefoot - Put oil or lotion between your toes. ** you should be prepared to work with dietitians as part of an interdisciplinary diabetes care team.
Biguanides (metformin): Action, therapeutic effects and side effects
Decreases the production of glucose in the liver and increasing the sensitivity of peripheral tissues to insulin. - decreases hepatic production of glucose - decreases intestinal absorption of glucose. - increases insulin sensitivity. - Metformin may be used with a sulfonylurea to more effectively control the blood glucose level. - Rare but potentially fatal side effect: Lactic acidosis has a 50% mortality rate. - Abdominal bloating, cramping, nausea, and diarrhea are common side effects of a biguanide such as metformin but are not ordinarily fatal. - Metformin can leave a metallic taste in the mouth, alt hough this effect is rare.

In obtaining a patient's general health history, what assessment data would indicate a need for further assessment of a patient's thyroid function?
Hypothyroidism - Changes in skin texture, thick, cold, dry skin - Changes in hair distribution - Puffiness, myxedema, preorbital edema, masklike affect - Goiter - Dysrhythmias, tachycardia, atrial fibrillation - Altered glucose levels: weight gain - Lethargy: state of mental sluggishness or somnolence - Constipation - Cold insensitivity - generalized edema - Seizure Hyperthyroidism - changes in skin texture, warm smooth, moist skin - hair loss - Exophthalmos - Goiter - Chest pain, dysrhythmias: tachycardia, atrial fibrillation - Hypertension - weight loss - Hyperreflexia - heat intolerance
Symptoms of Hyperthyroidism?
If there is too much thyroid hormone, every function of the body tends to speed up. - Nervousness, irritability, increased perspiration, heart racing, hand tremors, anxiety, difficulty sleeping, thinning of your skin, fine brittle hair and weakness in your muscles- especially in the upper arms and thighs. - You may have frequent bowel movements, but not diarrhea - You may lose weight despite a good appetite and, for women, menstrual flow may lighten and menstrual periods may occur less often. - initially have a lot of energy. However, as hyperthyroidism continues, the body tends to break down, so being tired is very common. ** At first the symptoms symptoms may be mistaken for simple nervousness due to stress. - In Graves' disease, which is the most common form of hyperthyroidism, the eyes may look enlarged because the upper lids are elevated. Sometimes, one or both eyes may bulge. Some patients have swelling of the front of the neck from an enlarged thyroid gland (a goiter)
Appropriate nursing diagnosis for patient with hyperthyroidism: Weight loss and hunger
Imbalanced nutrition: less than body requirements related to hyper-metabolism
What are the special nursing considerations in caring for the older adult diagnosed with hypothyroidism, who will be taking levothyroxine (Synthroid)? What would be a general teaching plan for a 35 year old patient receiving this medication?
In the older adult patient and the person with compromised cardiac status, a smaller initial dose is recommended because the usual dose may increase myocardial oxygen demand. The increased oxygen demand may cause angina and cardiac dysrhythmias. - Any chest pain experienced by a patient starting thyroid replacement should be reported immediately and an ECG and serum cardiac enzyme test must be performed. - In a patient without side effects, the dose is increased at 4-6 week intervals. it is important that the patient take replacement medication regularly. Lifelong thyroid replacement therapy is usually required.
In reviewing results of a patient's glycosylated hemoglobin (HbA1C), what information is the nurse able to determine?

What causes Hyperthyroidism?
Overproduction of thyroid hormone by the entire thyroid gland. This condition is also known as Graves' disease - antibodies in the blood that turn on the thyroid and cause it to grow and secrete too much thyroid hormone. - tends to run in families and occurs more often in young women - One or more nodules or lumps in the thyroid that may gradually grow and increase their activity so that the total output of thyroid hormone into the blood is greater than normal. This condition is known as toxic nodular or multi-nodular goiter. - Peo;e may temporarily have symptoms of hyperthyroidism if they have a condition called thyroiditis. ** This condition is caused by a problem with the immune system or a viral infection that causes the gland to leak stored thyroid hormone. - Also caused by taking too much thyroid hormone in tablet form.

In the patient admitted for tetany, what specific lab value(s) does the nurse plan to monitor, in addition to general monitoring of lab results?
Sudden decreases in calcium concentration cause tetany Decreased PTH levels and increased serum phosphate levels.
Hypothalamus
The hypothalamus and pituitary gland integrate communication between the nervous and endocrine system. The hypothalamus is located in the center of the diancephalon area of the brain and secretes 2 hormones: releasing hormones~(CRH) Corticotropin-releasing hormones, (TRH) Thyrotropin-releasing hormones, Growth hormone-releasing factor, Prolactin-releasing hormone. & Inhibiting hormones~Somatistatin-inhibits GH release, Prolactin-inhibiting hormone
The hormone secreting portion of the pancreas is referred to as:
The islets of Langerhans
Pituitary gland
The master gland; located at the base of the brain - Influenced by the hypothalamus; directly affects the function of the other endocrine glands - Promotes growth of body tissue, influences water absorption by the kidney, and controls sexual development and function.
In the patient displaying signs and symptoms of hypothyroidism, which lab values does the nurse plan to monitor, to determine if the condition is caused by malfunction of the anterior pituitary gland, or the thyroid gland?
The most common and reliable laboratory test for thyroid function are TSH and free T4. These valises, correlated with symptoms gathered form the history and physical examination, confirm the diagnosis. Serum TSH levels help determine the cause of hypothyroidism. Serum TSH is high when the defect is in the thyroid and low when it is in the pituitary or hypothalamus. An increase in TSH after TRH injection suggest hypothalamic dysfunction, whereas no change suggests anterior pituitary dysfunction. The presence of thyroid peroxidase antibodies suggests an autoimmune origin of the problem. Other abnormal laboratory findings are elevated cholestesterol and triglycerides, anemia, and increased creatine kinase.
Ovaries and testes
The ovaries are located in the pelvic cavity and produce estrogen and progesterone. - Testes are located in the scrotum, control the development of the secondary sex characteristics, and produce testosterone.
In planning teaching for the patient with hypothyroidism who has been admitted with myxedema coma, what considerations will the nurse take into account?
The patient who develops myxedema coma requires acute nursing care, often in a n intensive care setting. - Mechanical respiratory support and cardiac monitoring are frequently necessary. - Administer thyroid hormone replacement therapy and all other medications intravenously because paralytic ileum may be present in myxedema coma. Monitor the core temperature because hypothermia often occurs in myxedema coma. - Monitor the patient's progress by assessing vital signs, body weight, fluid intake and output, and visible edema. Cardiac assessment is especially important because the cardiovascular response to the hormone determines; the medication regimen. Not energy level and metal alertness.These should increase within 2 to 14 days and continue to rise steadily to normal levels. - It is important to provide written instructions, repeat the information often, and assess the patient's comprehension level. p1271
For the patient with hypoparathyroidism, what patient teaching is appropriate?
The patient with hypoparathyroidism needs instruction in the management of long-term drug therapy and nutrition. PTH replacement is not a recommended drug therapy because of the expense and the need for parenteral administration. - Oral calcium supplements of at least 1.5 to 3 g/day in divided doses are usually prescribed. Vitamin D is used in chronic and resistant hypocalcemia to enhance intestinal calcium absorption. - Preferred preparations are dihydrotachysterol (Hytakerol) and 1,25-dihydroxycholecalciferol (calcitriol (rocaltro). These drugs raise calcium levels rapidly and are quickly metabolized. Rapid metabolism is desired because vitamin D is a fat soluble vitamin and toxicity can cause irreversible renal impairment. - A calcium meal plan includes foods such as dark green vegetable, soybeans, and tofu. The the patient that foods congaing oxalic acid (spinach, rhubarb), physic acid (bran, whole grains), and phosphorus reduce calcium absorption. Instruct the patient about the need for lifelong treatment and follow up car including the monitoring of calcium levels three of four times a year.
Describe the water-soluble (protein) hormone receptor process.
The receptor is located in the cell membrane. The hormone-receptor interaction stimulates the production of a "second messenger" such as cAMP. cAMP works by activating enzymes to regulate intracellular activity.
What is Hyperthyroidism?
The term hyperthyroidism refers to any condition in which there is too much thyroid hormone produced in the body. In other words, the thyroid gland is overactive. Another term that you might hear for this problem is thyrotoxicosis, which refers to high thyroid hormone levels in the blood stream, irrespective of their source.

In the patient with diabetes type 2 who has developed peripheral neuropahty and peripheral artery disease, what information will the nurse use in patient teaching?
You should include the following instructions when teaching the patient and / or caregiver about diabetic foot care. 1. Wash feet daily with mild soap and warm water. First test water temperature with hands. 2. Pat feet dry gently, especially between toes. 3. Examine feet daily for cuts, blisters, swelling, and red tender areas. Do not depend on feeling sores. If eyesight is poor, have others inspect feet. 4. Use lanolin on feet to prevent skin form drying and cracking. Do not apply between toes. 5. Use mild foot powder on sweaty feet. 6. Do not use commercial remedies to remove calluses or corns. 7. Cleanse cuts with warm water and mild soap, covering with clean dressing. Do not use iodine, rubbing alcohol, or strong adhesive. 8. Report skin infections or non healing sores to health care provider immediately. 9. Cut toenails evenly with rounded contour of toes. Do not cut down corners. The best time to trim nails is after a shower or bath. 10. Separtate overlapping toes with cotton or lamb's wool. 11. Avoid open-toe, open heel, an high-heel shoes. Leather shoes are preferred to plastic ones. Wear slippers with soles. Do not go barefoot. Shake out shoes before putting on. 12. Wear clean, absorbent (cotton or wool) socks or stockings that have not been mended. Colored socks must be colorfast. 13. Do not wear clothing that leaves impressions, hindering circulation 14. Do not use hot water bottles or heating pads to warm feet. Wear socks for warmth. 15. Guard against frostbite. 16. Exercise feet daily either by walking or by flexing and extending feet in suspended position. Avoid prolonged sitting, standing, and crossing of legs.
Hormone
a chemical substance synthesized and secreted by a specific organ or tissue; inactivated in the liver and excreted thru the kidneys.
Two days following a self-managed hypoglycemic episode at home, the patient tells the nurse that his blood glucose levels since the episode have been between 80-90 mg/dL. The best response by the nurse is. a. "That is a good range for your glucose levels" b. "You should call your health care provider because you need to have your insulin increased." c. "That level is too low in view of your recent hypoglycemia, and you should increase your food intake" d. "You should only take half your insulin dosage for the next few days to get your glucose level back to normal"
a. "That is a good range for your glucose levels" Rationale: Blood glucose levels of 80 to 90 mg/dL (4.45-5 mmol/L) are within the normal range and are desired in the patient with diabetes, even following a recent hypoglycemic episode.
In nutritional management of all types of diabetes, it is important for the patient to a. eat regular meals at regular times b. restrict calories to promote moderate weight loss. c. eliminate sucrose and other simple sugars form the diet. d. limit saturated fat intake to 30% of dietary calorie intake.
a. eat regular meals at regular times. Rationale: The body requires food at regularly spaced intervals throughout the day and omission or delay of meals can result in hypoglycemia, especially for the patient taking insulin or oral hypoglycemic agents.
When obtaining subjective data from a patient during assessment of the endocrine system, the nurse asks specifically about a. energy level b. intake of vitamin C c. employment history d. frequency of sexual intercourse
a. energy level Rationale: The nurse should ask about energy levels, particularly compared with the patient's past energy level. Fatigue and hyperactivity are two common problems associated with endocrine problems.
To prevent hyperglycemia or hypoglycemia with exercise, the nurse teaches the patient using glucose-lowing agents that exercise should be undertaken. a. only after a 10- to 15-g carbohydrate snack is eaten. b. about 1 hour after eating, when blood glucose levels are rising. c. when glucose monitoring reveals that the blood glucose is in the normal range d. when blood glucose levels are high because exercise always has a hypoglycemic effect.
b. about 1 hour after eating, when blood glucose levels are rising. Rationale: During exercise, a diabetic person needs both adequate glucose to prevent exercise induced hypoglycemia and adequate insulin because e counterregulatory hormones are produced during the stress of exercise and may cause hyperglycemia.
Following the teaching of foot care to a diabetic patient, the nurse determines that additional instruction is needed when the patient says. a. "I should wash my feet daily with soap and warm water" b. "I should always wear shoes to protect my feet form injury" c. "If my feet are cold, I should wear socks instead of using a heating pad" d. "I'll know if I have sores or lesions on my feet because they will be painful."
d. "I'll know if I have sores or lesions on my feet because they will be painful" Rationale: Complete or partial loss of sensitivity of the feet is common with peripheral neuropathy of diabetes, and diabetics may suffer foot injury and ulceration without ever having pain. Feet must be inspected during daily care for any cuts, blisters, swelling, or reddened areas.
A patient with Graves' disease asks the nurse what caused the disorder. The best response by the ruse is, a. The cause of Graves' disease is not know, although it is thought to be genetic" b. "It is usually associated with goiter formation from an iodine deficiency over a long period of time" c. "Antibodies develop against thyroid tissue and destroy it, causing a deficiency of thyroid hormone" d. "In genetically susceptible persons, antibodies are formed that cause excessive thyroid hormone secretion'
d. "in genetically susceptible persons, antibodies are formed that cause excessive thyroid hormone secretion" Rationale: In Graves' disease, antibodies to the TSH receptor are domed, attach to the receptors, and stimulate the thyroid gland to release triiodothyronine (T3), thyroxine (T4), or both, creating hyperthyroidism. The disease is not directly genetic, but individuals appear to have a genetic susceptibility to the develop autoimmune antibodies.
Which of the following patients would a nurse plant to teach how to prevent or delay the development of diabetes? a. A 62 year old obese whit e man. b. An obese 50 year old Hispanic Woman. c. A child whose father has type 1 diabetes. d. A 34 year old woman whose parents both have type 2 diabetes.
d. A 34 year old woman whose parents both have type 2 diabetes Rationale: Type 2 diabetes has a strong genetic influence, and offspring of parents who both have type 2 diabetes have increased chance of developing it.
