A nurse is teaching an older adult patient who has diabetes mellitus about preventing the long-term complications of retinopathy and nephropathy.
Which of the following instructions should the nurse include?

Choice A rationale

A turkey, lettuce, and whole-grain bread sandwich is high in fiber, which can worsen the symptoms of an acute diverticulitis flare. During a flare-up, the inflamed diverticula need time to heal, and a high-fiber diet can increase stool bulk and pressure within the colon, exacerbating pain and inflammation. The recommended diet for an acute flare is low-fiber or clear liquids to rest the bowel.

Choice B rationale

Chicken soup broth, gelatin, and a clear sports drink constitute a clear liquid diet, which is the appropriate dietary management for an acute diverticulitis flare. This diet provides hydration and some electrolytes without introducing fiber or solid food, which allows the inflamed bowel to rest and begin the healing process. This selection indicates a correct understanding of the teaching provided by the nurse.

Choice C rationale

A spinach salad with low-fat dressing is high in insoluble fiber. During an acute diverticulitis flare, a high-fiber diet can worsen the inflammation and symptoms by increasing bulk and pressure in the colon. This can lead to increased pain and discomfort and potentially complicate the condition. This food choice is not appropriate and indicates a misunderstanding of the teaching.

Choice D rationale

Oatmeal is a high-fiber food that should be avoided during an acute diverticulitis flare. High-fiber foods can increase bowel motility and pressure in the inflamed colon, which can worsen abdominal pain, cramping, and inflammation. A low-fiber or clear liquid diet is necessary to allow the bowel to rest and recover, and oatmeal is not suitable for this purpose.

Choice A rationale

The patient's severe diarrhea poses a significant risk for fluid and electrolyte imbalances, particularly hypokalemia and dehydration, which can lead to life-threatening cardiac dysrhythmias. Assessing heart rate and rhythm first is a priority because it directly evaluates the most immediate and potentially fatal consequence of these imbalances, ensuring the patient's hemodynamic stability and preventing cardiac arrest.

Choice B rationale

Percussion of the abdomen, while part of a comprehensive abdominal assessment, is a lower priority in this acute situation. It provides information about distension and gas patterns but does not address the immediate physiological threat of hypovolemia and electrolyte shifts that can precipitate cardiac complications. This action can be performed after the more critical vital signs are assessed.

Choice C rationale

Inspecting oral mucosa provides a general indication of hydration status. However, this is a subjective assessment and less precise than directly assessing heart rate and rhythm, which can indicate the severity of electrolyte imbalances and dehydration. The priority is to assess for the most critical complication, which is cardiac dysrhythmia.

Choice D rationale

Assessing recent dietary intake is important for understanding the patient's nutritional status and potential triggers for diarrhea. However, this is a historical data-gathering step and does not address the immediate, life-threatening physiological changes occurring from severe diarrhea. This information is a low priority in an acute situation where the patient's vital signs are at risk.
