Rationale: A laceration is a wound that is produced by the tearing of soft body tissue. This type of wound is often irregular and jagged. A laceration wound is often contaminated with bacteria and debris from whatever object caused the cut. 37. The nurse is planning care for a client admitted with a diagnosis of pheochromocytoma. Which intervention has the highest priority for inclusion in this client’s plan of care? • Monitor blood pressure frequently Rationale: A pheochromocytoma is a rare, catecholamine-secreting tumor that may precipitate lifethreatening hypertension. The tumor is malignant in 10% of cases but may be cured completely by surgical removal. Although pheochromocytoma has classically been associated with 3 syndromes—von Hippel-Lindau (VHL) syndrome, multiple endocrine neoplasia type 2 (MEN 2), and neurofibromatosis type 1 (NF1)—there are now 10 genes that have been identified as sites of mutations leading to pheochromocytoma. 38. When caring for a client who has acute respiratory distress syndrome (ARDS), the nurse elevates the head of the bed 30 degrees. What is the reason for this intervention? • To reduce abdominal pressure on the diaphragm • to promote retraction of the intercostal accessory muscle of respiration • to promote bronchodilation and effective airway clearance • to decrease pressure on the medullary center which stimulates breathing Rationale: a semi-sitting position is the best position for matching ventilation and perfusion and for decreasing abdominal pressure on the diaphragm, so that the client can maximize breathing. 39. When assessing a mildly obese 35-year-old female client, the nurse is unable to locate the gallbladder when palpating below the liver margin at the lateral border of the rectus abdominal muscle. What is the most likely explanation for failure to locate the gallbladder by palpation? • The client is too obese • Palpating in the wrong abdominal quadrant • Deeper palpation technique is needed • The gallbladder is normal Rationale: a normal healthy gallbladder is not palpable 40. A woman with an anxiety disorder calls her obstetrician’s office and tells the nurse of increased anxiety since the normal vaginal delivery of her son three weeks ago. Since she is breastfeeding, she stopped taking her antianxiety medications, but thinks she may need to start taking them again because of her increased anxiety. What response is best for the nurse to provide this woman? • Describe the transmission of drugs to the infant through breast milk • Encourage her to use stress relieving alternatives, such as deep breathing exercises • Explain that anxiety is a normal response for the mother of a 3-week-old. • Inform her that some antianxiety medications are safe to take while breastfeeding
