Complete Chapter Questions With Answers
Sample Questions Are Posted Below
| 1. | A patient is scheduled for an exploratory surgery for cancer. What will cause the release of adrenocorticotropic hormone in response to this patient’s psychological and physiological stress? | |
| A) | Growth hormone release–inhibiting hormone (Somatostatin) | |
| B) | Corticotropin-releasing hormone or factor (CRH or CRF) | |
| C) | Growth hormone–releasing hormone (GHRH) | |
| D) | Thyrotropin-releasing hormone (TRH) | |
| Ans: | B | |
| Feedback: | ||
| Corticotropin-releasing hormone or factor (CRH or CRF) causes release of corticotropin (adrenocorticotropic hormone) in response to stress and threatening stimuli. Growth hormone release–inhibiting hormone (somatostatin) inhibits release of growth hormone. Growth hormone–releasing hormone causes the release of growth hormone in response to low blood levels of GH. Thyrotropin-releasing hormone causes the release of TSH in response to stress, such as cold. | ||
| 2. | A patient has had surgery. After the surgical procedure, the patient starts to shiver and chill. What hormone will be released in response to the reaction to cold? | |
| A) | Thyroid-stimulating hormone | |
| B) | Luteinizing hormone | |
| C) | Corticotropin | |
| D) | Somatostatin | |
| Ans: | A | |
| Feedback: | ||
| Thyroid-stimulating hormone is released in response to stress, such as exposure to cold. Luteinizing hormone is released in response to gonadotropin-releasing hormone. Corticotropin stimulates the adrenal cortex to produce corticosteroids. Somatostatin inhibits the release of growth hormone. | ||
| 3. | A patient is suspected of having Cushing’s disease. What hormone is used in the diagnosis of this disorder? | |
| A) | Growth hormone | |
| B) | Adrenocorticotropic hormone | |
| C) | Thyroid-stimulating hormone | |
| D) | Corticotropin-releasing hormone | |
| Ans: | D | |
| Feedback: | ||
| Corticotropin-releasing hormone can be used in the diagnosis of Cushing’s disease. Growth hormone is released in response to low blood levels of growth hormone. Corticotropin-releasing hormone causes the release of corticotropin (adrenocorticotropic hormone) in response to stress. Thyroid-stimulating hormone regulates the secretion of thyroid hormones. | ||
| 4. | A young man has begun weight training. Which hormone will be released in response to the increase in the size and number of muscle cells? | |
| A) | Growth hormone | |
| B) | Adrenocorticotropic hormone | |
| C) | Thyroid-stimulating hormone | |
| D) | Corticotropin-releasing hormone | |
| Ans: | A | |
| Feedback: | ||
| Growth hormone stimulates the growth of body tissues, including growth of muscle cells. Corticotropin-releasing hormone causes the release of corticotropin (adrenocorticotropic hormone) in response to stress. Thyroid-stimulating hormone regulates the secretion of thyroid hormones. | ||
| 5. | An adult is diagnosed with an increased low-density lipoprotein cholesterol level. What hormone level may be low based on this diagnosis? | |
| A) | Adrenocorticotropic hormone (ACTH) | |
| B) | Oxytocin | |
| C) | Growth hormone | |
| D) | Somatostatin | |
| Ans: | C | |
| Feedback: | ||
| In adults, deficient growth hormone can cause increased fat, reduced skeletal and heart muscle mass, reduced strength, reduced ability to exercise, and worsened cholesterol levels (increased low-density lipoprotein cholesterol). Adrenocorticotropic hormone, oxytocin, and somatostatin do not affect low-density lipoprotein. | ||
