Question

The nurse is caring for a patient with suspected diverticulitis. The nurse would be most prudent in questioning which of the following diagnostic tests ordered? A. Colonoscopy B. Barium enema C. Complete blood count D. Computed tomography (CT) scan

Short answer

Answer: A. Colonoscopy

Step-by-step solution

Understanding diverticulitis

Diverticulitis is a digestive disease characterized by the inflammation of small pouches (diverticula) in the large intestine. It can cause severe abdominal pain, fever, and changes in bowel movements. To diagnose this condition, healthcare providers use different tests to examine the colon and rule out other potential causes of the patient's symptoms.

Evaluating each diagnostic test

A. Colonoscopy: A colonoscopy is a procedure where a thin, flexible tube with a camera at the end (colonoscope) is inserted into the patient's rectum to examine the lining of their colon. It is useful in diagnosing diverticulitis, but it may be risky to perform during an acute episode, as it can increase the risk of perforation. B. Barium enema: A barium enema is a diagnostic test that involves filling the colon with a contrast material (barium) to visualize the intestinal lining through X-ray images. This test can help identify diverticula and other abnormalities but carries a similar risk of perforation as a colonoscopy. C. Complete blood count (CBC): A complete blood count is a blood test that measures the number of different types of blood cells, including white blood cells, red blood cells, and platelets. Elevated white blood cell levels can indicate inflammation or infection, which may suggest diverticulitis. This test is non-invasive and has no risks associated with it. D. Computed tomography (CT) scan: A CT scan is an imaging method that uses X-rays and computer processing to generate detailed cross-sectional images of the body's internal structures. A CT scan can help identify signs of diverticulitis, such as inflammation around the diverticula and abscesses. This test is non-invasive and has relatively low risks.

Identifying the most prudent diagnostic test to question

Comparing the various diagnostic tests, it is evident that colonoscopy (option A) and barium enema (option B) carry a heavier risk of perforation, especially during an acute episode of diverticulitis. Therefore, it would be prudent for a nurse to question these tests over the non-invasive options (options C and D), which have fewer potential complications. The diagnostic test that would be most prudent in questioning is A. Colonoscopy, due to the higher possibility of causing perforation during an acute episode of diverticulitis.

Key concepts

Nursing Diagnostics

Nursing diagnostics play a crucial role in identifying and managing various health conditions. It involves gathering and analyzing patient data to pinpoint specific problems and determine the best course of action. In the context of diverticulitis, nursing diagnostics help distinguish the condition from other possible gastrointestinal issues. This ensures the patient receives appropriate treatment quickly and safely.

When performing diagnostics, nurses often use a combination of observational skills, patient history, and test results. These diagnostics are vital in guiding the medical team to make informed decisions regarding patient care. Tests like complete blood count (CBC) and computed tomography (CT) scans offer relevant information. They are typically prioritized due to their non-invasive nature and lower associated risks.

Diverticulitis Assessment

Diverticulitis assessment involves evaluating the symptoms and medical tests to determine if a patient has inflammation in the diverticula. Symptoms may include intense stomach pain, fever, and alterations in bowel habits. For accurate diagnosis, healthcare providers may order different tests.

While a CT scan is a valuable tool, revealing detailed images of the digestive tract and highlighting any inflammation or abscesses, it's essential to consider if other tests are necessary. A complete blood count can also indicate inflammation through elevated white blood cell levels. However, more invasive procedures like colonoscopies and barium enemas carry risks and should be used cautiously, especially during an acute episode. The nurse's role in questioning certain tests underlines their importance in ensuring patient safety.

Patient Safety in Diagnostics

Patient safety in diagnostics is paramount, particularly when dealing with sensitive conditions like diverticulitis. Safety involves selecting the most appropriate tests that minimize risks while providing accurate results. It's crucial to evaluate the benefits and potential harm of each diagnostic option.

Colonoscopy and barium enema tests, commonly used for gastrointestinal evaluations, pose higher risks of complications like perforation in the presence of inflamed diverticula. Non-invasive options such as a CT scan or a complete blood count significantly reduce these risks, making them safer alternatives. By questioning more invasive tests, nurses help protect patients and ensure their health is not unnecessarily jeopardized by diagnostics.

Nursing Care Plans

Nursing care plans are vital in managing patient care through personalized strategies that address their unique needs, especially in diverticulitis cases. These plans often begin with a thorough assessment and diagnostics, followed by expert guidance on treatment paths.

A well-crafted nursing care plan incorporates not only the current symptoms and diagnostics but also anticipates potential complications. This proactive approach can include pain management strategies, infection prevention, and necessary dietary modifications. Nurses play an essential role in crafting these plans to ensure optimal patient outcomes, continuously adapting them based on the patient's response to treatment.
