- A.
Dopamine agonists
- B.
Somatropin
- C.
Somatostatin analogs
- D.
Mineralocorticoids
Correct Answer
C. Somatostatin analogsExplanation
Somatostatin analogs are used in the treatment of growth hormone excess. Somatostatin is a hormone that inhibits the release of growth hormone, among other hormones, from the pituitary gland. By using somatostatin analogs, which are synthetic versions of somatostatin, the excessive production of growth hormone can be suppressed, helping to regulate its levels in the body. Dopamine agonists, somatropin, and mineralocorticoids are not typically used in the treatment of growth hormone excess.Rate this question:

_______________ regulate sodium and potassium reabsorption in the collecting tubules of the kidney
Correct Answer
MineralocorticoidsExplanation
Mineralocorticoids are a class of hormones that regulate the reabsorption of sodium and potassium in the collecting tubules of the kidney. These hormones, such as aldosterone, act on the cells of the tubules to increase the reabsorption of sodium ions and the excretion of potassium ions. This helps to maintain the balance of these electrolytes in the body and regulate blood pressure. Therefore, mineralocorticoids play a crucial role in maintaining fluid and electrolyte balance in the body.Rate this question:

Which test is used for diagnosis of Addison’s disease
- A.
Dexamethasone suppression test
- B.
Short cosyntropin-stimulation test
Correct Answer
B. Short cosyntropin-stimulation testExplanation
The short cosyntropin-stimulation test is used for the diagnosis of Addison's disease. This test involves administering a synthetic form of adrenocorticotropic hormone (ACTH), called cosyntropin, to stimulate the adrenal glands to produce cortisol. Blood samples are taken before and after the administration of cosyntropin to measure cortisol levels. In individuals with Addison's disease, the adrenal glands do not respond adequately to the stimulation, resulting in low cortisol levels. Therefore, the short cosyntropin-stimulation test can help identify adrenal insufficiency and diagnose Addison's disease.Rate this question:

Which test is used in the Diagnosis of Cushing syndrome?
- A.
Dexamethasone suppression test
- B.
Short cosyntropin-stimulation test
Correct Answer
A. Dexamethasone suppression testExplanation
The Dexamethasone suppression test is used in the diagnosis of Cushing syndrome. This test involves giving a high dose of synthetic glucocorticoid (dexamethasone) to the patient and measuring cortisol levels in the blood or urine. In a person without Cushing syndrome, the high dose of dexamethasone should suppress cortisol production. However, in individuals with Cushing syndrome, cortisol levels will not be suppressed, indicating an abnormal response to dexamethasone. Therefore, the Dexamethasone suppression test is a reliable diagnostic tool for identifying Cushing syndrome.Rate this question:

In Addison's disease, a person will retain too much?
- A.
Calcium
- B.
Sodium
- C.
Chloride
- D.
Potassium
Correct Answer
D. PotassiumExplanation
In Addison's disease, the adrenal glands do not produce enough cortisol and aldosterone. Aldosterone is responsible for regulating the balance of electrolytes in the body, including potassium. Without enough aldosterone, the body retains too much potassium, leading to high levels of potassium in the blood. This can cause symptoms such as muscle weakness, fatigue, and irregular heart rhythms. Therefore, in Addison's disease, a person will retain too much potassium.Rate this question:

- A.
Hyperglycemia
- B.
hypertension
- C.
Hyperkalemia
- D.
Sodium retention
Correct Answer(s)
A. Hyperglycemia
B. hypertension
D. Sodium retentionExplanation
Hydrocortisone is a corticosteroid medication commonly used to treat inflammation and immune system disorders. One of the side effects of hydrocortisone treatment is hyperglycemia, which refers to high blood sugar levels. This occurs because hydrocortisone can increase glucose production in the liver and decrease the body's ability to use insulin effectively. Another side effect is hypertension, or high blood pressure, which can result from the drug's impact on fluid balance and blood vessel constriction. Additionally, hydrocortisone can cause sodium retention, leading to fluid retention and potential swelling.Rate this question:

Hypercortisolism (Cushing syndrome) is clinical condition resulting from chronic exposure to excessive circulating levels of glucocorticoids
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because hypercortisolism, also known as Cushing syndrome, is indeed a clinical condition that occurs when there is chronic exposure to excessive levels of glucocorticoids in the body. Glucocorticoids are a type of hormone that is produced by the adrenal glands and are involved in regulating various bodily functions, including metabolism and immune response. When there is an overproduction or prolonged exposure to glucocorticoids, it can lead to a range of symptoms associated with Cushing syndrome, such as weight gain, high blood pressure, and muscle weakness.Rate this question:

Select one: ALL are used in the treatment of Cushing Syndrome but which is the most desired?
- A.
Surgical removal of ACTH producing tumor
- B.
Irradiation of pituitary tumor
- C.
Steroidogenesis inhibitors
- D.
Adrenolytic agents
- E.
Neuromodulators of ACTH release
- F.
Glucocorticoid receptor antagonist
Correct Answer
B. Irradiation of pituitary tumorExplanation
Irradiation of pituitary tumor is the most desired treatment for Cushing Syndrome because it specifically targets the tumor in the pituitary gland that is producing excessive ACTH. By using radiation therapy, the tumor cells can be destroyed, leading to a decrease in ACTH production and ultimately a reduction in cortisol levels. This treatment option is often preferred over surgical removal of the tumor because it is less invasive and carries fewer risks. Steroidogenesis inhibitors, adrenolytic agents, neuromodulators of ACTH release, and glucocorticoid receptor antagonists may also be used in the treatment of Cushing Syndrome, but they are not the most desired treatment option.Rate this question:

____________________ promotes reabsorption of sodium from renal tubules.
Correct Answer
AldosteroneExplanation
Aldosterone is a hormone that promotes the reabsorption of sodium from the renal tubules. This hormone is produced by the adrenal glands and plays a crucial role in regulating the body's electrolyte balance. By increasing the reabsorption of sodium, aldosterone helps to maintain proper fluid balance and blood pressure. It also stimulates the excretion of potassium and hydrogen ions, further contributing to electrolyte balance. Overall, aldosterone ensures that the body retains the necessary amount of sodium for proper physiological functioning.Rate this question:

- A.
Hypokalemia,
- B.
Metabolic alkalosis
- C.
Increased plasma volume
- D.
Hypertension
Correct Answer(s)
A. Hypokalemia,
B. Metabolic alkalosis
C. Increased plasma volume
D. HypertensionExplanation
Excessive levels of aldosterone, whether produced by tumors or overdosage with synthetic mineralocorticoids, can lead to a variety of effects. One of these effects is hypokalemia, which refers to low levels of potassium in the blood. Aldosterone promotes the excretion of potassium in the urine, leading to a decrease in potassium levels. Another effect is metabolic alkalosis, which is an increase in the pH of the blood. Aldosterone causes increased reabsorption of sodium and excretion of hydrogen ions, resulting in alkalosis. Additionally, aldosterone promotes increased plasma volume by enhancing the reabsorption of sodium and water in the kidneys. This increased plasma volume can contribute to hypertension, or high blood pressure.Rate this question:
