REVIEW QUESTIONS—TEST PREPARATION The correct answers are in boldface. 5. (3, 4, 5) are correct. Antidiuretic hormone increases water reabsorption by the kidney tubules, while aldosterone and cortisol increase reabsorption of sodium ions and, therefore, water by the kidneys to the blood. Both affect blood volume and blood pressure. (1) influences metabolic rate; (2 and 6) affect glucose level. 6. (3) is correct. The final urine voided at 24 hours must be added to the specimen. (1) is incorrect. The first, not the last, urine voided is discarded. (2) is incorrect. A separate container is not necessary. (4) is incorrect. All urine produced in 24 hours is necessary for the test. 7. (1) is correct. The heart rate is typically elevated in hyperthyroidism. (2) could cause release of hormone and exacerbate symptoms. (3) evaluates diabetes, not thyroid function. (4) is incorrect. A buffalo hump is present when there is too much cortisol, not thyroid hormone. 8. (3) is correct. This directly answers her question. Further testing must be done to determine a definite diagnosis. (1) is incorrect. She may have cancer of the thyroid, but she needs further testing; also, the nurse does not make a medical diagnosis. (2) is not true. (4) is incorrect. A cold spot is not normal. 9. 0.15 mg 1,000 mcg = 150 mcg 1 mg 10. (2, 4) are correct. The incretin hormones glucagon-like peptide (GLP-1) and gastric inhibitory polypeptide (GIP) help regulate blood sugar by increasing insulin secretion and decreasing glucagon secretion from the pancreas. (1) is not correct. These hormones do not have any direct effect on gastric enzymes. (3, 5) are not correct. Incretin hormones do not have any influence on cellular uptake of glucose or glucose clearance by kidneys.
