  • Which hormone is secreted by the small intestine in response to the presence of acidic chyme?
    Secretin is secreted by the small intestine in response to acidic chyme.
  • A client is to receive enoxaparin. The nurse would administer this drug by which route?
    Enoxaparin is administered subcutaneously.
  • What is the function of luteinizing hormone?
    Stimulates ovulation
  • Which of these glands produces a hormone that maintains the balance of calcium in the blood?
    The parathyroid glands produce parathyroid hormone, which maintains calcium balance.
  • What is the function of the thymus?
    The thymus is involved in the maturation of T-cells for the immune system.
  • What is the difference between endocrine and exocrine glands?
    Endocrine glands secrete hormones into the bloodstream, while exocrine glands secrete substances through ducts to an epithelial surface.
  • What endocrine gland secretes triiodothyronine?
    The thyroid gland secretes triiodothyronine (T3).
  • Which cells secrete testosterone?
    Leydig cells in the testes secrete testosterone.
  • How does antidiuretic hormone exert its effects?
    Increasing water reabsorption
  • Which endocrine gland is located in the brain?
    The pituitary gland is located in the brain.
  • What hormone produced in the adrenal cortex increases blood sugar levels?
    Cortisol increases blood sugar levels.
  • When vasoactive medications are administered, what should be monitored?
    Monitor blood pressure and heart rate.
  • A nurse is teaching a client about preventing osteoporosis. Which teaching point is correct?
    Ensure adequate intake of calcium and vitamin D, and engage in weight-bearing exercises.
  • Which organ releases glucagon into the bloodstream in response to low blood glucose?
    The pancreas releases glucagon in response to low blood glucose.
  • Which organ produces insulin?
    The pancreas produces insulin.
  • Which gland in the endocrine system primarily controls the body's response to a stressful situation?

  • How do nonsteroid hormones differ from steroid hormones?
    Nonsteroid hormones are water-soluble and bind to receptors on the cell membrane, while steroid hormones are lipid-soluble and bind to receptors inside the cell.
  • What is the effect of antidiuretic hormone on the cells of the collecting duct?
    Antidiuretic hormone increases the permeability of the collecting duct cells to water, promoting reabsorption.
  • How do exocrine glands differ from endocrine glands?
    Exocrine glands secrete substances through ducts to an epithelial surface, while endocrine glands secrete hormones directly into the bloodstream.
  • For which condition is Pentoxifylline (Trental) used?
    Pentoxifylline is used to improve blood flow in patients with peripheral artery disease.
  • Which hormone is secreted from the adrenal medulla?
    Epinephrine is secreted from the adrenal medulla.
  • The function of which hormone is to help control blood pressure?
    Aldosterone helps control blood pressure.
  • The parathyroid glands respond to which type of stimulus?
    The parathyroid glands respond to changes in blood calcium levels.
  • How are the nervous system and endocrine system similar?
    Both systems are involved in regulating body functions and maintaining homeostasis.
