Correct Answer is B

Explanation

Choice A reason:Bubbling in the water seal chamber with exhalation can be normal, indicating that air is being evacuated from the pleural space.

Choice B reason:Crepitus, or subcutaneous emphysema, can indicate that air is leaking into the tissue around the chest tube site, which is a serious complication that requires immediate attention.

Choice C reason:

Movement of the trachea toward the unaffected side can indicate tension pneumothorax, a life-threatening condition that also requires immediate attention.

Choice D reason:If the eyelets of the chest tube are not visible, it may simply mean that the tube is inserted fully, which is not an immediate cause for concern unless other symptoms are present.

A. Hematemesis B. Abdominal bloating C. Epigastric discomfort D. Dyspepsia

Correct Answer is A

Explanation

Choice A reason: Hematemesis Hematemesis, or vomiting blood, is a serious symptom that usually indicates bleeding in the upper gastrointestinal tract. This could be due to a severe peptic ulcer, among other conditions1. The blood may appear red or black, and the condition can cause a person to go into hypovolemic shock, which can lead to organ failure and death if not treated immediately. Therefore, hematemesis should be identified as the priority symptom in this case. While all these symptoms can be associated with peptic ulcer disease, hematemesis is the most serious and should be prioritized due to the risk of significant blood loss and potential for hypovolemic shock.

Choice B reason: Abdominal bloating Abdominal bloating is a symptom that can be caused by various conditions, including indigestion, overeating, and certain medical conditions. While it can be uncomfortable, it is generally not as immediately life-threatening as hematemesis.

Choice C reason: Epigastric discomfort Epigastric discomfort refers to pain or discomfort in the upper abdomen, below the ribs. It can be caused by conditions such as acid reflux, GERD, overeating, lactose intolerance, and others. While it can be a symptom of a peptic ulcer, it is not typically as urgent as hematemesis.

Choice D reason: Dyspepsia Dyspepsia, also known as indigestion, can cause symptoms such as bloating, heartburn, and feeling full too quickly8910. It can be caused by a variety of factors, including certain foods, overeating, and medical conditions like GERD. While it can be a symptom of a peptic ulcer, it is generally not as immediately life-threatening as hematemesis.
