    HORMONE THAT WHEN OVER PRODUCED CAN CAUSE ACROMEGLY

    • ACTH

    • GH

    • FSH

    Correct Answer
    A. GH
    Explanation
    When growth hormone (GH) is overproduced, it can cause a condition called acromegaly. Acromegaly is characterized by the enlargement of certain body parts, such as the hands, feet, and facial features, due to excessive bone and tissue growth. GH is produced by the pituitary gland and plays a crucial role in regulating growth and development. When there is an excess of GH, it disrupts the normal balance and leads to abnormal growth, resulting in acromegaly. Therefore, GH is the hormone that, when overproduced, can cause acromegaly.

    IN DIABETES INSIPIDUS, WHICH HORMONE IS LACKING?

    • ADH

    • PROLACTIN

    • TSH

    Correct Answer
    A. ADH
    Explanation
    In diabetes insipidus, the hormone that is lacking is ADH (antidiuretic hormone). ADH is responsible for regulating the body's water balance by controlling the amount of water reabsorbed by the kidneys. In diabetes insipidus, the body is unable to produce or respond to ADH, leading to excessive thirst and urination. This condition can be caused by damage to the hypothalamus or pituitary gland, which are responsible for producing and releasing ADH.

    DIABETES INSIPIDUS CAN LEAD TO SIGNS OF HYPOVOLEMIC SHOCK.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Diabetes insipidus is a condition characterized by excessive thirst and urination due to the inability of the body to properly regulate fluid balance. In severe cases, this excessive fluid loss can lead to dehydration and a decrease in blood volume, which can result in hypovolemic shock. Hypovolemic shock occurs when there is a significant loss of blood or fluid in the body, leading to a decrease in blood pressure and inadequate oxygen and nutrient supply to the organs. Therefore, it is true that diabetes insipidus can lead to signs of hypovolemic shock.

    Rate this question:

  • 5. 

    DIABETES INSIPIDUS CAUSES AN ______________ IN URINE OUTPUT , WHICH IS OPPOSITE OF HYPOVOLEMIA.

    • DECREASE

    • INCREASE

    • NO CHANGE

    Correct Answer
    A. INCREASE
    Explanation
    Diabetes insipidus is a condition characterized by excessive thirst and urination. It is caused by a deficiency of antidiuretic hormone (ADH) or a resistance to its effects. ADH helps regulate water balance in the body by reducing urine output. In diabetes insipidus, the lack of ADH leads to an increase in urine output, resulting in excessive urination. This is opposite to hypovolemia, which is a condition characterized by low blood volume. In hypovolemia, the body tries to conserve water by reducing urine output. Therefore, the correct answer is "increase" because diabetes insipidus causes an increase in urine output.

    • MINERALOCORTICOIDS

    • SEX HORMONES

    • GLUCOCORTICOIDS

    Correct Answer
    A. GLUCOCORTICOIDS
    Explanation
    Glucocorticoids are a class of steroid hormones that aid in glucose metabolism and exhibit anti-inflammatory properties. They regulate the metabolism of carbohydrates, proteins, and fats, and help to maintain normal blood sugar levels. Additionally, they suppress the immune system and reduce inflammation, making them effective in the treatment of conditions such as allergies, asthma, and autoimmune diseases. Glucocorticoids are produced by the adrenal glands and play a crucial role in various physiological processes in the body.

    • WOMEN

    • INFANTS

    Correct Answer
    A. WOMEN
    Explanation
    Graves' disease is an autoimmune disorder that affects the thyroid gland. It is more commonly seen in women than in men. Women are about 10 times more likely to develop Graves' disease compared to men. The exact reason for this gender difference is not known, but it is believed to be due to a combination of genetic and hormonal factors. Hormonal changes during puberty, pregnancy, and menopause may also contribute to the higher prevalence of Graves' disease in women.

    THE ADRENAL MEDULLA RELEASES THESE HORMONES DURING STRESS. CHECK ALL THAT APPLY

    • EPINEPHRINE

    • LEVODOPA

    • DOPAMINE

    Correct Answer
    A. EPINEPHRINE
    Explanation
    During times of stress, the adrenal medulla releases hormones to prepare the body for a fight-or-flight response. One of these hormones is epinephrine, also known as adrenaline. Epinephrine increases heart rate, blood pressure, and glucose levels, providing the body with a burst of energy to deal with the stressful situation. Levodopa and dopamine are not hormones released by the adrenal medulla during stress.

    GOITERS  DEVELOP IN RESPONSE TO LACK OF_________.

    • TSH

    • IODINE

    • SODIUM

    Correct Answer
    A. IODINE
    Explanation
    Goiters develop in response to a lack of iodine. Iodine is an essential nutrient that is needed for the production of thyroid hormones. When there is a deficiency of iodine in the diet, the thyroid gland enlarges in an attempt to produce more hormones, leading to the development of a goiter. The thyroid-stimulating hormone (TSH) is responsible for regulating the thyroid gland, but it is not directly related to the development of goiters. Sodium, on the other hand, does not play a significant role in the development of goiters.

    MASTER GLAND OF BODY

    • TROPIC

    • PITUITARY

    • THALAMUS

    Correct Answer
    A. PITUITARY
    Explanation
    The pituitary gland, also known as the master gland of the body, is responsible for producing and releasing hormones that regulate various bodily functions. It is located at the base of the brain and is divided into two parts: the anterior pituitary and the posterior pituitary. The anterior pituitary produces hormones that control growth, metabolism, and reproduction, while the posterior pituitary stores and releases hormones that control water balance and milk production. Therefore, the pituitary gland is considered the master gland because it plays a crucial role in regulating the functions of other endocrine glands in the body.

    SIADH CAN LEAD TO WATER INTOXICATION

    • True

    • False

    Correct Answer
    A. True
    Explanation
    SIADH (syndrome of inappropriate antidiuretic hormone) is a condition where the body produces too much antidiuretic hormone (ADH), leading to the kidneys retaining more water. This excess water retention can result in dilution of electrolytes in the body, including sodium, which is essential for proper functioning of cells. If the sodium levels become too low, it can cause a condition called water intoxication or hyponatremia. Therefore, it is true that SIADH can lead to water intoxication.

    CUSHINGS SYNDROME IS CAUSED BY EXCESS OF GLUCOCORTICOIDS.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Cushing's syndrome is indeed caused by an excess of glucocorticoids. Glucocorticoids are a type of steroid hormone that is produced by the adrenal glands. In Cushing's syndrome, there is an overproduction of glucocorticoids, which can be caused by various factors such as long-term use of corticosteroid medications or tumors in the adrenal glands or pituitary gland. The excess glucocorticoids can lead to a wide range of symptoms including weight gain, high blood pressure, muscle weakness, and mood changes. Therefore, the statement "Cushing's syndrome is caused by excess of glucocorticoids" is true.

    GRAVES DISEASE IS A AUTOIMMUNE DISORDER.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Graves' disease is indeed an autoimmune disorder. It is characterized by an overactive thyroid gland, which leads to symptoms such as weight loss, rapid heartbeat, sweating, and irritability. In this condition, the immune system mistakenly attacks the thyroid gland, causing it to produce excessive amounts of thyroid hormones. This autoimmune response is what distinguishes Graves' disease from other thyroid disorders.

    IF CUSHINGS SYNDROME IS A RESULT OF CORTICOSTEROID THERAPY, YOU MUST

    • STOP THEM IMEDIATELY TO PREVENT DEATH

    • REDUCE DOSE AND SLOWLY DISCONTINUE

    • REMAIN ON THERAPHY THE REST OF THEIR LIFE

    Correct Answer
    A. REDUCE DOSE AND SLOWLY DISCONTINUE
    Explanation
    If Cushing's syndrome is a result of corticosteroid therapy, reducing the dose and slowly discontinuing the therapy is the appropriate course of action. This is because abruptly stopping corticosteroid therapy can lead to adrenal insufficiency, which can be life-threatening. By gradually reducing the dose and slowly discontinuing the therapy, the body can adjust and the risk of complications can be minimized.

    GIGANTISM INCLUDES ALL BUT

    • WEIGHT INCREASE

    • INCREASED MUSCLE

    • NORMAL HEIGHT

    Correct Answer
    A. NORMAL HEIGHT
    Explanation
    Gigantism is a condition characterized by excessive growth and height. It is caused by an overproduction of growth hormone during childhood and adolescence. This excessive growth results in individuals with gigantism being much taller than average. Therefore, the statement "normal height" is incorrect because gigantism is associated with abnormally tall stature. The other options, weight increase and increased muscle, are both consistent with the symptoms of gigantism.

    GRAVES DISEASE IS CAUSED BY

    • HYPOTHYROIDISIM

    • HYPERTHYROIDISM

    • NEITHER

    Correct Answer
    A. HYPERTHYROIDISM
    Explanation
    Graves' disease is caused by hyperthyroidism. This means that the thyroid gland is overactive and produces an excessive amount of thyroid hormones. Graves' disease is an autoimmune disorder where the immune system mistakenly attacks the thyroid gland, leading to its overstimulation. This results in symptoms such as weight loss, rapid heartbeat, tremors, and anxiety. Hypothyroidism, on the other hand, is the opposite condition where the thyroid gland is underactive and produces insufficient thyroid hormones. Therefore, it is not the cause of Graves' disease.

    • FATAL

    • CURABLE WITH A THYROIDECTOMY

    • PAINFULL AND FAST SPREADING

    Correct Answer
    A. CURABLE WITH A THYROIDECTOMY
    Explanation
    Cancer of the thyroid is usually curable with a thyroidectomy. A thyroidectomy is a surgical procedure that involves the removal of the thyroid gland, which is where the cancer typically originates. By removing the cancerous thyroid gland, the spread of the cancer can be stopped, and the patient can be cured. It is important to note that the success of the treatment may depend on various factors such as the stage of the cancer and the overall health of the patient. However, in general, a thyroidectomy is an effective treatment option for thyroid cancer.

    ANTAGONIST TO CALCITONIN

    • ADRENALINE

    • ADH

    • PARATHYROID HORMONE

    Correct Answer
    A. PARATHYROID HORMONE
    Explanation
    Parathyroid hormone is the correct answer because it acts as an antagonist to calcitonin. Calcitonin is a hormone that helps regulate calcium levels in the blood by promoting calcium deposition in the bones. Parathyroid hormone, on the other hand, works in opposition to calcitonin by increasing blood calcium levels. It does this by stimulating the release of calcium from the bones, increasing calcium absorption in the intestines, and reducing calcium excretion in the kidneys. Therefore, parathyroid hormone acts as an antagonist to calcitonin in maintaining calcium homeostasis.

    ALL ARE SEEN IN GRAVES DISEASE EXCEPT.

    • BULGING EYES

    • NECK EDEMA

    • REDUCED T4 LEVELS

    Correct Answer
    A. REDUCED T4 LEVELS
    Explanation
    Graves' disease is an autoimmune disorder that causes overactivity of the thyroid gland, leading to hyperthyroidism. One of the characteristic symptoms of Graves' disease is bulging eyes, also known as exophthalmos, due to the buildup of tissue behind the eyes. Neck edema, or swelling in the neck, can also occur in Graves' disease due to the enlargement of the thyroid gland. However, reduced T4 levels are not typically seen in Graves' disease, as it is associated with increased production of thyroid hormones. Therefore, the presence of reduced T4 levels would be inconsistent with the diagnosis of Graves' disease.

    SIADH , SYNDROME OF INAPPROPRIATE ADH,  CAUSES.

    • INCREASED NA

    • LOSS OF BODY FLUID

    • DECREASED URINARY OUTPUT

    Correct Answer
    A. DECREASED URINARY OUTPUT
    Explanation
    The correct answer is "decreased urinary output". In SIADH (Syndrome of Inappropriate ADH), there is an excessive release of antidiuretic hormone (ADH) which leads to water retention and dilutional hyponatremia. This results in decreased urinary output as the body tries to conserve water. Other causes of SIADH include increased secretion of ADH by the pituitary gland, certain medications, lung diseases, and brain disorders.

    Stress is known to activate the release of antidiuretic hormone (ADH) in the body, which can lead to the development of syndrome of inappropriate antidiuretic hormone secretion (SIADH). SIADH is a condition characterized by excessive release of ADH, resulting in water retention and dilutional hyponatremia. Therefore, it can be inferred that stress is indeed the key activator of SIADH.

    A SERIOUS CONDITION THAT MAY DEVELOP AFTER RADIOACTIVE IODINE TREATMENT OF THE THYROID

    • HYPERTHYROIDISM

    • HYPOTHYROIDISM

    • IODINE ALLERGIES

    Correct Answer
    A. HYPOTHYROIDISM
    Explanation
    Hypothyroidism is a condition that may develop after radioactive iodine treatment of the thyroid. This treatment involves the use of radioactive iodine to destroy or shrink the thyroid gland, which can lead to an underactive thyroid. Hypothyroidism occurs when the thyroid gland does not produce enough thyroid hormones, resulting in symptoms such as fatigue, weight gain, and depression. Therefore, hypothyroidism is the correct answer in this case.

    ADDISON PATIENTS SHOULD CARRY AN EMERGENCY DOSE OF_________.

    • EPINEPHRINE

    • HYDROCORTISONE

    • INSULIN

    Correct Answer
    A. HYDROCORTISONE
    Explanation
    Addison's disease is a condition where the adrenal glands do not produce enough cortisol, which is a hormone that helps regulate the body's response to stress. In times of stress or emergency, the body requires higher levels of cortisol. Therefore, patients with Addison's disease should carry an emergency dose of hydrocortisone, which is a synthetic form of cortisol, to prevent an adrenal crisis and manage their condition effectively. Epinephrine is typically used for severe allergic reactions, and insulin is used to manage diabetes.

    A DECREASE IN ADH CAUSES YOU TO RETAIN FLUID.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A decrease in ADH (antidiuretic hormone) actually causes you to lose fluid, not retain it. ADH is responsible for regulating the amount of water reabsorbed by the kidneys. When ADH levels are low, the kidneys excrete more water, leading to increased urine production and fluid loss. Therefore, the statement is incorrect and the correct answer is False.
