A client continues to report post-surgical incision pain at a level of 9 out of 10 after pain medication is given. The next dose of pain medicine is not due for another hour. What should the critically thinking nurse do first?

Choice A reason: Assessment is the first and most important phase of the nursing process, as it involves collecting and analyzing data about the patient's health status, needs, and preferences. The nurse should have assessed the patient's blood pressure before administering the antihypertensive medication, as it could have been contraindicated or required a dosage adjustment. By failing to do so, the nurse put the patient at risk of hypotension and its complications.

Choice B reason: Planning is the second phase of the nursing process, in which the nurse sets goals and outcomes for the patient's care and selects appropriate interventions. The nurse did not make an error in this phase, as the administration of the antihypertensive medication was part of the plan of care for the patient with hypertension.

Choice C reason: Diagnosis is the third phase of the nursing process, in which the nurse identifies the patient's actual or potential health problems based on the assessment data. The nurse did not make an error in this phase, as the diagnosis of hypertension was accurate and supported by the patient's history and vital signs.

Choice D reason: Evaluation is the fourth and final phase of the nursing process, in which the nurse measures the patient's progress and outcomes and modifies the plan of care as needed. The nurse did not make an error in this phase, as the re-checking of the blood pressure and the recognition of the patient's symptoms were part of the evaluation process. However, the nurse should have also notified the provider and implemented interventions to treat the hypotension.

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.
