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"

Answer and Explanation

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 ["A","C"]

Explanation

A. Planning for periods of rest during activities and monitoring the client's oxygen saturation are essential interventions for a client with pneumonia. Rest helps conserve energy and reduces the workload on the respiratory system, while monitoring oxygen saturation ensures that the client is maintaining adequate oxygen levels, which is crucial in pneumonia.
B. Placing the client on strict fluid restriction is not appropriate for pneumonia. In fact, adequate hydration is important to help thin respiratory secretions and facilitate expectoration.
C. Placing the client on oxygen is often necessary for clients with pneumonia, especially if they are hypoxic or have difficulty maintaining adequate oxygen levels. Supplemental oxygen supports the respiratory system and improves oxygenation.
D. Restricting the client's smoking to 5 cigarettes per day is not an appropriate intervention. Smoking should be completely stopped to help reduce the risk of further respiratory complications. Smoking cessation is a priority in managing respiratory conditions like pneumonia

A. An intolerance to the feedings B. Esophageal perforation with fistula formation into the lung C. Extension of the tumor into the aorta D. Leakage of fluids into the mediastinum

Correct Answer is B

Explanation

A. An intolerance to the feedings might cause discomfort, but it would not typically cause increasing pain, fever, and dyspnea. These symptoms are more indicative of a serious complication.
B. Esophageal perforation with fistula formation into the lung is the most likely cause of these symptoms. A perforation can lead to leakage of gastric contents into the pleural space or mediastinum, causing fever, pain, and respiratory distress. The formation of a fistula between the esophagus and the lung would lead to dyspnea.
C. Extension of the tumor into the aorta is a rare complication that would typically manifest with symptoms related to cardiovascular issues, not gastrointestinal symptoms like fever and dyspnea.
D. Leakage of fluids into the mediastinum is a possible cause of the symptoms, but esophageal perforation with a fistula into the lung is more directly linked to these specific symptoms, especially dyspnea.
