When scheduling diagnostic tests, which of the following would the nurse schedule last?

Esophagogastroduodenoscopy (EGD)

Barium Enema

Abdominal ultrasound

Abdominal CT scan

Answer and Explanation

The Correct Answer is D

A.   An EGD involves inserting a flexible tube with a camera through the mouth into the esophagus, stomach, and duodenum. It often requires the patient to be NPO (nothing by mouth) for several hours beforehand, but it can typically be done before other imaging tests.
B.   A barium enema is a radiologic examination of the large intestine that uses a barium contrast solution. Patients may need to follow a special diet and take laxatives prior to the test. It's often done earlier in the testing schedule to clear the bowel before other procedures.
C.   An abdominal ultrasound is a non-invasive imaging test that does not require any special preparations, although patients are often advised to fast for a few hours beforehand for optimal results. It can typically be scheduled relatively flexibly in relation to other tests.
D.   An abdominal CT scan may involve the use of contrast agents, which can be given orally or intravenously. If the patient has had a barium study (like a barium enema) before the CT scan, it’s generally recommended to schedule the CT scan last. This is because residual barium in the gastrointestinal tract can interfere with the imaging results of a CT scan.

Correct Answer is B

Explanation

A. C. difficile is primarily transmitted via the fecal-oral route, not through respiratory droplets. While masks can be important for respiratory infections, they are not a standard precaution for C. difficile.
B. C. difficile infections require contact precautions to prevent the spread of spores. This includes wearing gloves and gowns when entering the room and ensuring proper hand hygiene protocols are followed. It helps protect other patients and staff from potential infection.
C. The diagnosis of a C. difficile infection is typically made through stool testing for the presence of the bacteria or its toxins. Blood tests are not effective for diagnosing C. difficile infections.
D. While alcohol-based hand sanitizers are effective for many pathogens, they are not effective against
C. difficile spores. Instead, hand hygiene should be performed with soap and water to effectively remove the spores from hands.

A. Sudden abdominal pain B. Hyperactive bowel sounds C. Bradycardia D. Increased blood pressure

Correct Answer is A

Explanation

A. Sudden and severe abdominal pain is a classic sign of gastrointestinal perforation. When an ulcer perforates, it allows gastric contents to spill into the abdominal cavity, leading to irritation and inflammation of the peritoneum (peritonitis). This can cause acute, intense pain that often starts suddenly and is typically localized to the area of the perforation.
B. Hyperactive bowel sounds may occur due to irritation or inflammation in the gastrointestinal tract but are not a definitive indicator of perforation. In fact, with perforation, bowel sounds may be diminished or absent due to the associated peritonitis and ileus that can occur after a perforation.
C. Bradycardia (a slow heart rate) is not a typical finding associated with gastrointestinal perforation. In fact, perforation often leads to tachycardia (increased heart rate) as a compensatory response to pain, shock, or blood loss. Bradycardia may indicate other issues but is not directly linked to perforation.
D. Increased blood pressure is also not typically associated with gastrointestinal perforation. Patients may experience hypotension due to shock from blood loss and infection resulting from perforation.
