A nurse is caring for a client who states, "I did not take my medication because my partner forgot to remind me." The nurse should identify that the client is demonstrating which of the following defense mechanisms?

Choice A reason: This is the correct answer because paralytic ileus is a condition in which the intestinal motility is decreased or absent, resulting in the inability to pass gas or stool. It is a common complication of abdominal surgery, as the manipulation of the bowel can cause inflammation and nerve damage. The nurse should monitor the client for signs of bowel obstruction, such as abdominal distension, nausea, vomiting, and pain.

Choice B reason: This is not the correct answer because Clostridium difficile colitis is a condition in which the normal flora of the colon is disrupted by antibiotic therapy, allowing the overgrowth of a toxin-producing bacteria that causes inflammation and diarrhea. It is not a common complication of abdominal surgery, but rather a risk associated with prolonged hospitalization and antibiotic use.

Choice C reason: This is not the correct answer because constipation is a condition in which the stool is hard, dry, and difficult to pass. It is not a common complication of abdominal surgery, but rather a side effect of opioid analgesics, which can slow down the bowel movements. The nurse should encourage the client to increase fluid and fiber intake, and use stool softeners as prescribed.

Choice D reason: This is not the correct answer because fecal impaction is a condition in which a large mass of stool is stuck in the rectum, preventing the passage of gas or stool. It is not a common complication of abdominal surgery, but rather a result of chronic constipation, dehydration, or immobility. The nurse should assess the client for signs of impaction, such as abdominal cramping, rectal pressure, and leakage of liquid stool.

Choice A reason: Fluid volume deficit is a condition in which the body loses more fluid than it gains, resulting in dehydration, hypotension, and electrolyte imbalances. It is not a complication of IV fluid therapy, but rather a reason for initiating it.

Choice B reason: Fluid volume excess is a condition in which the body retains more fluid than it needs, resulting in edema, hypertension, and heart failure. It is a potential complication of IV fluid therapy, especially in older adults who have reduced renal function and cardiac output. The nurse's assessment findings of crackles, shortness of breath, and jugular vein distention are indicative of fluid overload and pulmonary congestion.

Choice C reason: Speed shock is a systemic reaction that occurs when a substance is administered too rapidly into the bloodstream, causing adverse effects such as chest pain, dyspnea, hypotension, and cardiac arrest. It is not a complication of IV fluid therapy, but rather a risk associated with IV medication administration.

Choice D reason: Pulmonary embolism is a blockage of one or more pulmonary arteries by a blood clot, fat, or air, causing impaired gas exchange, chest pain, dyspnea, and hemoptysis. It is not a complication of IV fluid therapy, but rather a possible outcome of venous thromboembolism, which can be prevented by using anticoagulants and mechanical devices.
