| 49. | Which action would be most appropriate when evaluating a client’s neck for thyroid enlargement? |
| A) | Inspect changes in pigmentation in the neck. |
| B) | Perform repeated palpation of the thyroid gland. |
| C) | Palpate the thyroid gland gently. |
| D) | Examine the skin of the neck for excessive oiliness. |
| Ans: | C |
| Feedback: | |
| The nurse should inspect the neck for thyroid enlargement and gently palpate the thyroid gland. Repeated palpation of the thyroid in case of thyroid hyperactivity can result in a sudden release of a large amount of thyroid hormones, which may have serious implications. Pigment changes in the neck and excessive oiliness of the skin are not related to assessment for thyroid enlargement. |
| 2. | The nurse is reviewing the plan of care for a client with a disorder of the thyroid gland. Which diagnostic test would the nurse expect the physician to order to evaluate thyroid hormones? |
| A) | Magnetic resonance imaging |
| B) | Radioimmunoassay |
| C) | Computed tomography (CT) |
| D) | Cortisol level determination |
| Ans: | B |
| Feedback: | |
| A radioimmunoassay determines the concentration of a substance in plasma. A T3 determination by radioimmunoassay evaluates thyroid hormone function. A CT or magnetic resonance imaging scan is done to detect a suspected tumor and to determine organ size and placement. Cortisol levels determine adrenal hyperfunction. |
| 3. | During physical examination of a client with a suspected endocrine disorder, the nurse assesses the body structures. The nurse gathers this data based on the understanding that it is an important aid in which of the following? |
| A) | Detecting evidence of hormone hypersecretion |
| B) | Detecting information about possible tumor growth |
| C) | Determining the presence or absence of testosterone levels |
| D) | Determining the size of the organs and location |
| Ans: | A |
| Feedback: | |
| The evaluation of body structures helps the nurse detect evidence of hypersecretion or hyposecretion of hormones. This helps in the assessment of findings that are unique to specific endocrine glands. Radiographs of the chest or abdomen are taken to detect tumors. Radiographs also determine the size of the organ and its location. |
| 4. | A client is scheduled for a diagnostic test to measure blood hormone levels. The nurse expects that this test will determine which of the following? |
| A) | The concentration of a substance in plasma |
| B) | Details about the size of the organ and its location |
| C) | The functioning of endocrine glands |
| D) | The client’s blood sugar level |
| Ans: | C |
| Feedback: | |
| Measuring blood hormone levels helps determine the functioning of endocrine glands. A radioimmunoassay determines the concentration of a substance in plasma. The measurement of blood hormone levels will not reveal a client’s blood sugar level. Radiographs of the chest or abdomen determine the size of the organ and its location. |
| 5. | An instructor is preparing a teaching plan for a class on the various pituitary hormones. Which hormone would the instructor include as being released by the posterior pituitary gland? |
| A) | Somatotropin |
| B) | Prolactin |
| C) | Oxytocin |
| D) | Adrenocorticotropic hormone |
| Ans: | C |
| Feedback: | |
| The posterior pituitary gland released oxytocin and antidiuretic hormone. Somatotropin, prolactin, and adrenocorticotropic hormone are released by the anterior pituitary gland. |
