When scheduling diagnostic tests, which of the following would the nurse schedule last?
Esophagogastroduodenoscopy (EGD)
Barium Enema
Abdominal ultrasound
Abdominal CT scan
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 D
Explanation
A. This option includes nausea, which may occur but is not a primary indication for surgery. Belching can happen with digestive issues but does not specifically relate to GERD or the need for Nissen Fundoplication. Weight gain is not directly associated with GERD symptoms and may occur post-surgery due to changes in diet or activity levels.
B. Esophageal reflux is a central symptom of GERD and a primary reason for considering Nissen Fundoplication. While flatulence can occur with various gastrointestinal issues, it is not a hallmark symptom of GERD. Chronic cough may result from acid reflux irritating the throat, but this option does not emphasize the most common and significant symptoms related to the surgery.
C. Epigastric pain may occur in GERD but is not a defining symptom prompting surgery. Hoarseness can result from acid reflux affecting the vocal cords, yet it is not a primary reason for Nissen Fundoplication. Diarrhea is not typically associated with GERD and does not connect to the reasons for the procedure.
D. Heartburn is the classic symptom that drives many patients to seek surgical intervention. Gastroesophageal reflux directly indicates the condition being treated, and chest pain can be a significant discomfort caused by acid reflux.
Correct Answer is B
Explanation
A. Distended neck veins are typically associated with conditions that lead to increased central venous pressure, such as heart failure or fluid overload, not pyloric stenosis. Therefore, this option is not relevant to pyloric stenosis.
B. Projectile vomiting is a classic symptom of pyloric stenosis. This occurs due to the obstruction caused by the thickened pylorus, which prevents food from passing into the duodenum. The vomiting is forceful and occurs shortly after feeding, making this option a hallmark of the condition.
C. A ridged (or rigid) abdomen can indicate underlying issues, such as peritonitis or other abdominal emergencies, but it is not a typical finding associated specifically with pyloric stenosis. Pyloric stenosis may lead to some degree of abdominal distension, but not necessarily to a ridged abdomen.
D. Red currant jelly stools are associated with intussusception, not pyloric stenosis. This type of stool appears when there is a mix of blood and mucus due to bowel obstruction or ischemia, but it is not a symptom of pyloric stenosis.
