a. ACTH b. Oxytocin c. ADH d. TSH Study These Flashcards B The hypothalamus secretes oxytocin. The anterior pituitary secretes ACTH. The posterior pituitary secretes ADH. The anterior pituitary secretes TSH. 56 A nurse is teaching the staff about oxytocin. Which information should the nurse include? Target cells for oxytocin are located in the: a. Renal tubules b. Thymus c. Liver d. Uterus Study These Flashcards
D Oxytocin causes uterine contraction and lactation in women and may have a role in sperm motility in men. Oxytocin does not stimulate the renal tubules; it stimulates the uterus. Oxytocin does not stimulate the thymus; it stimulates the uterus. Oxytocin does not stimulate the liver; it stimulates the uterus. 57 A 50-year-old male patient is deficient in ADH production. Which of the following assessment findings would the nurse expect to find? a. Increased blood volume b. Increased urine osmolality c. Increased urine volume d. Increased arterial vasoconstriction Study These Flashcards C With deficient ADH, the kidneys would not concentrate urine leading to increased urine output. Blood volume would decrease with increased renal excretion of fluid. Urine osmolality would decrease. Arteries would dilate with deficient ADH production. 58 A 70-year-old female has brittle bones secondary to osteoporosis. Her primary care provider prescribes calcitonin to: a. Activate vitamin D b. Stimulate osteoclastic activity c. Inhibit calcium resorption from bones d. Promote thyroid hormone release Study These Flashcards C Calcitonin lowers serum calcium levels by inhibition of bone-resorbing osteoclasts. Calcitonin inhibits bone-resorbing osteoclasts; it does not activate vitamin D. Calcitonin inhibits bone-resorbing osteoclasts; not stimulate it. Calcitonin inhibits bone-resorbing osteoclasts; it does not promote thyroid hormone release. 59 Which nutrient would the nurse encourage the patient to consume for thyroid hormone synthesis? a. Zinc b. Sodium c. Iodine d. Calcium Study These Flashcards
C Iodine is necessary for the synthesis of thyroid hormone. Iodine, not zinc, is necessary for synthesis of thyroid hormone. Iodine, not sodium, is necessary for synthesis of thyroid hormone. Iodine, not calcium, is necessary for synthesis of thyroid hormone. 60 A nurse is reviewing lab results. Which of the following lab results would slow down the rate of parathyroid hormone secretion? a. Increased serum calcium levels b. Decreased serum calcium levels c. Decreased levels of TSH d. Increased levels of TSH Study These Flashcards A An increase in serum calcium inhibits parathyroid hormone (PTH) secretion. An increase, not a decrease, in serum calcium inhibits PTH secretion. Thyroid-stimulating hormone would not affect PTH secretion. Thyroid-stimulating hormone would not affect PTH secretion.
