    In order to form urine the nephron must perform three major processes: glomerular filtration, tubular reabsorption, tubular secretion 

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because the nephron, which is the functional unit of the kidney, performs three major processes to form urine. Glomerular filtration is the first step, where blood is filtered through the glomerulus to remove waste products and excess water. Tubular reabsorption then occurs, where essential substances such as glucose, water, and electrolytes are reabsorbed back into the bloodstream. Finally, tubular secretion takes place, where additional waste products and ions are actively transported from the blood into the tubules for excretion in urine. These processes are essential for the formation of urine in the nephron.

    • PSA plus digital rectal exam

    • PSA only

    • DRE only

    • No screening recommended

    Correct Answer
    A. PSA plus digital rectal exam
    Explanation
    The recommended screening for prostate includes both PSA (Prostate-Specific Antigen) testing and a digital rectal exam (DRE). PSA testing measures the levels of PSA in the blood, which can be an indicator of prostate cancer. However, PSA levels can also be elevated due to other conditions, so combining it with a DRE provides a more comprehensive evaluation. The DRE involves a doctor manually examining the prostate gland through the rectum to check for any abnormalities or signs of cancer. This combined approach is considered the most effective method for early detection of prostate cancer.

    The process by which most of the material in the nephron moves back into the blood is called

    • Secretion

    • Reabsorption

    • Filtration

    Correct Answer
    A. Reabsorption
    Explanation
    Reabsorption is the correct answer because it refers to the process in which most of the material in the nephron, such as water, glucose, amino acids, and ions, moves back into the blood. This process occurs primarily in the renal tubules of the nephron, where the filtered substances are selectively reabsorbed to maintain the body's balance of fluids, electrolytes, and pH levels. Secretion, on the other hand, is the process of actively transporting certain substances, such as drugs and toxins, from the blood into the renal tubules for excretion in urine. Filtration is the initial step in urine formation, where blood pressure forces water and small solutes to pass through the filtration membrane into the renal tubules.

    The sign shown in the image is known as exophthalmos, which is the protrusion of the eyeballs. This condition is a characteristic feature of Graves disease, an autoimmune disorder that affects the thyroid gland. In Graves disease, the immune system mistakenly attacks the thyroid gland, causing it to produce excessive amounts of thyroid hormone. This hormonal imbalance can lead to various symptoms, including the bulging of the eyes. Therefore, the correct answer is Graves disease.

    Diabetes type 2 may be autoimmune in most cases

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement suggests that diabetes type 2 is autoimmune in most cases. However, this is not true. Diabetes type 2 is primarily caused by a combination of genetic and lifestyle factors such as obesity, sedentary lifestyle, and poor diet. While there may be some cases where autoimmune factors play a role, it is not the predominant cause of diabetes type 2. Therefore, the correct answer is False.

    Gigantism is an excess growth hormone that occurs in:

    • Children

    • Adults

    • Any age

    • Males only

    Correct Answer
    A. Children
    Explanation
    Gigantism is a condition characterized by excessive growth hormone production, leading to abnormal growth and development. It typically occurs during childhood when the growth plates in the long bones are still open and can continue growing. In adults, the growth plates have closed, so excess growth hormone production results in acromegaly, a condition characterized by enlargement of the hands, feet, and facial features. Therefore, the correct answer is children, as gigantism primarily affects individuals during their growing years.

You notice that over the years his voice is become deeper and his hands have been getting larger. He also tells you that he shoe size has increased over the years. All physical exam findings are normal including weight and height. A picture is shown below. What is the most likely cause of his condiiton?

    • Smoking

    • Anabolic steroids

    • Anterior pituitary tumor producing excess growth hormone

    • Cortisol levels

    • Posterior pituitary tumor producing excess ADH and OXT

    Correct Answer
    A. Anterior pituitary tumor producing excess growth hormone
    Explanation
    The most likely cause of the patient's condition is an anterior pituitary tumor producing excess growth hormone. This is indicated by the patient's symptoms of deepening voice, enlarged hands, and increased shoe size, which are consistent with acromegaly. Acromegaly is caused by excessive production of growth hormone, typically due to a pituitary adenoma. The normal physical exam findings, including weight and height, suggest that the patient's condition is localized to the pituitary gland rather than a systemic issue such as smoking or anabolic steroid use.

    A 45 year-old patient with insulin resistance, obesity, using medications for diabetes, and is on a diet and exercise program most likely has:

    • Diabetes type I

    • Diabetes insipidus

    • Diabetes type II

    • Hyperadrenalism

    Correct Answer
    A. Diabetes type II
    Explanation
    A 45-year-old patient with insulin resistance, obesity, using medications for diabetes, and on a diet and exercise program most likely has diabetes type II. Insulin resistance and obesity are common risk factors for type II diabetes. The fact that the patient is using medications for diabetes further supports this diagnosis. Diabetes type I is unlikely since it typically presents at a younger age and is characterized by a lack of insulin production. Diabetes insipidus is a condition that affects the kidneys and causes excessive thirst and urination, which is not mentioned in the scenario. Hyperadrenalism is a condition related to excessive adrenal gland activity and is not directly related to the symptoms described in the scenario.
