Hesi Medsurg Practice Quiz Questions and Verified Answers 2024

The nurse is assessing a client admitted from the emergency room with gastrointestinal bleeding related to peptic ulcer disease (PUD). Which physiological factors can produce ulceration? (Select all that apply.) A) Vagal stimulation. B) An increased level of stress. C) Decreased duodenal inhibition. D) Hypersecretion of hydrochloric acid. E) An increased number of parietal cells. - Correct selections are (A, C, D, and E). Hypersecretion of gastric juices (D) and an increased number of parietal cells (E) that stimulate secretion are most often the causes of ulceration. Vagal stimulation (A) and decreased duodenal inhibition (C) also increase the secretion of caustic fluids. An increased stress level is not physiologic and is not a direct cause of ulceration (B). The healthcare provider prescribes high-protein, high-fat, low-carbohydrate diet with limited fluids during meals for a client recovering from gastric surgery. The client asks the nurse what the purpose is for this type of diet. Which rationale should be included in the nurse's explanation to this client? A) It is quickly digested. B) It does not cause diarrhea. C) It does not dilate the stomach. D) It is slow to leave the stomach. - This type of diet is slowly digested and is slow to leave the stomach (D). Because of its density from proteins and fats, and the reduction of fluids with the meal, the possibility of dumping syndrome is reduced. (A, B, and C) are incorrect rationales. Which preexisting diagnosis places a client at greatest risk of developing superior vena cava syndrome? A) Carotid stenosis. B) Steatosis hepatitis. C) Metastatic cancer. D) Clavicular fracture. - Superior vena cava syndrome occurs when the superior vena cava (SVC) is compressed by outside structures, such as a growing tumor that impedes the return blood flow to the heart. Superior vena cava syndrome is likely to occur with metastatic cancer (C) from a primary tumor in the upper lobe of the right lung that compresses the superior vena cava. (A, B, and D) do not result in SVC syndrome. The nurse should explain to a client with lung cancer that pleurodesis is performed to achieve which expected outcome? A) Prevent the formation of effusion fluid. B) Remove fluid from the intrapleural space. C) Debulk tumor to maintain patency of air passages. D) Relieve empyema after pneumonectomy. - Instillation of a sclerosing agent to create pleurodesis (adherence of the parietal and visceral pleura) is aimed at preventing the formation of pleural effusion fluid (A). (B) refers to thoracentesis. (C) is achieved by surgical resection. (D) is treated by closed-chest drainage. A client with a markedly distended bladder is diagnosed with hydronephrosis and left hydroureter after an IV pyelogram. The nurse catheterizes the client and obtains a residual urine volume of 1650 ml. This finding supports which pathophysiological cause of the client's urinary tract obstruction? A) Obstruction at the urinary bladder neck. Feedback: CORRECT B) Ureteral calculi obstruction. Feedback: INCORRECT C) Ureteropelvic junction stricture. Feedback: INCORRECT D) Partial post-renal obstruction due to ureteral stricture. - Hydroureter (dilation of the renal pelvis), vesicoureteral reflux (backward movement of urine from the lower to upper urinary tracts), and hydronephrosis (dilation or enlargement of the renal pelvis and calyces) result from post-renal obstruction which can consequently result in chronic pyelonephritis and renal atrophy. Ascending urinary reflux occurs when normal ureteral peristaltic pressure is met with an increase in urinary pressure occurring during bladder filling if the urinary bladder neck is obstructed (A). A large residual urine does not occur with (B, C, and D) because the urine can not get to the bladder.
