A nurse is teaching student nurses about different types of medical conditions that affect the gastrointestinal system, when a student asks her about the cause of esophageal varices. What is an appropriate answer by the nurse when asked about a potential cause of esophageal varices?
"Obesity has been a known cause of esophageal varices"
"It is caused by smoking"
"It is caused by high blood pressure"
"It is caused by chronic liver disease"
The Correct Answer is D
A. While obesity can contribute to various health issues, it is not a direct cause of esophageal varices.
B. Smoking is harmful to overall health, but it is not specifically known to cause esophageal varices.
C. High blood pressure, especially systemic hypertension, is not a direct cause of esophageal varices. However, portal hypertension, which can be caused by liver disease, is the main factor in the development of esophageal varices.
D. Chronic liver disease, particularly cirrhosis, leads to portal hypertension, which in turn causes the veins in the esophagus to become engorged and prone to bleeding, resulting in esophageal varices. This is the most appropriate cause for esophageal varices.

Correct Answer is B
Explanation
A. "Moon phase" is not a correct term related to prednisone use. The term "moon face" refers to the round, puffy face that can result from prolonged steroid use, which is a side effect, but it is not something the patient needs to notify the healthcare provider about unless it is accompanied by other severe symptoms.
B. Taking the steroid medication as prescribed is essential. Prednisone is a corticosteroid, and missing doses or abruptly stopping the medication can lead to complications such as adrenal insufficiency. It's important for the client to adhere to the prescribed regimen to manage inflammation and minimize the risk of side effects.
C. Steroids like prednisone can cause increased blood glucose levels, so it's important for the client to monitor blood glucose more frequently. If blood glucose levels exceed 150 mg/dL, they should notify their healthcare provider, but this is not the immediate management strategy for this scenario.
D. Prednisone should be taken with food to reduce gastrointestinal irritation, not on an empty stomach. Taking it without food can increase the risk of stomach upset and ulcers, particularly in patients with inflammatory bowel disease.
