A nurse is caring for a patient who is being admitted for an acute exacerbation of ulcerative colitis.
Which of the following actions should the nurse take first?
Obtain a dietary history from the patient.
Review the patient's electrolyte values.
Check the patient's perianal skin integrity.
Investigate the patient's emotional concerns.
The Correct Answer is B
Choice A rationale
Obtaining a dietary history is important in managing ulcerative colitis, as certain foods can exacerbate symptoms. However, in an acute exacerbation, the immediate priority is to address physiological instability, which electrolyte imbalances can significantly contribute to.
Choice B rationale
During an acute exacerbation of ulcerative colitis, patients can experience significant fluid and electrolyte losses due to frequent and bloody diarrhea. Reviewing electrolyte values, such as potassium, sodium, and magnesium, is the priority to identify and promptly correct any imbalances that could lead to cardiac arrhythmias or other complications. Normal ranges for serum electrolytes are: Sodium: 135-145 mEq/L, Potassium: 3.5-5.0 mEq/L, Chloride: 98-106 mEq/L, Bicarbonate: 22-26 mEq/L, Calcium: 8.5-10.5 mg/dL, Magnesium: 1.5-2.5 mEq/L.
Choice C rationale
Checking perianal skin integrity is important because frequent diarrhea can lead to skin breakdown. However, this assessment is secondary to addressing potential life-threatening electrolyte imbalances that can occur during an acute flare-up.
Choice D rationale
Addressing the patient's emotional concerns is a crucial aspect of holistic care for patients with chronic conditions like ulcerative colitis. However, in the context of an acute exacerbation, the immediate physiological needs, such as identifying and correcting electrolyte imbalances, take precedence.

Correct Answer is D
Explanation
Choice A rationale
Decreasing fluid intake can lead to dehydration and constipation, which would further impede peristalsis rather than promote it. Adequate hydration is essential for maintaining bowel regularity and facilitating the movement of intestinal contents.
Choice B rationale
Offering the bedpan every 2 hours does not directly stimulate peristalsis. While it provides an opportunity for bowel elimination, it does not address the underlying issue of decreased intestinal motility associated with paralytic ileus.
Choice C rationale
Increasing protein intake does not directly promote peristalsis. While protein is important for overall healing, it does not have a significant impact on stimulating bowel motility. Fiber intake is more directly related to promoting bowel function.
Choice D rationale
Increased ambulation stimulates peristalsis by promoting intestinal motility. Physical activity helps to move gas and fluids through the intestines, reducing the risk of paralytic ileus, which is a functional obstruction of the bowel often occurring after surgery.
Correct Answer is A
Explanation
Choice A rationale
Acetaminophen is often recommended as a first-line analgesic for managing mild to moderate pain associated with osteoarthritis. It acts centrally to inhibit prostaglandin synthesis in the central nervous system and block pain impulses peripherally. Unlike nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen lacks significant anti-inflammatory properties and does not typically cause gastrointestinal irritation or bleeding, making it a safer initial option for chronic pain management in many individuals.
Choice B rationale
Decreasing foods high in purines is a dietary recommendation for patients with gout, a type of inflammatory arthritis caused by the accumulation of uric acid crystals in the joints. Osteoarthritis, however, is a degenerative joint disease resulting from cartilage breakdown and is not directly linked to purine metabolism or uric acid levels. Therefore, this dietary modification is not relevant to managing osteoarthritis.
Choice C rationale
While elevating an affected joint can help reduce swelling and discomfort, it is generally recommended for acute inflammation or injury rather than the chronic pain of osteoarthritis. Large pillows under the knee or hip for extended periods can actually promote joint flexion contractures and should be avoided. Proper positioning usually involves maintaining joint alignment and avoiding prolonged static positions.
Choice D rationale
Applying heat can provide pain relief and muscle relaxation for osteoarthritis by increasing blood flow to the area and reducing stiffness. However, the temperature should be comfortably warm, not below body temperature, to achieve these therapeutic effects. Heat application typically ranges from 104°F to 113°F (40°C to 45°C) for optimal benefit without causing burns.
