A nurse is reviewing the arterial blood gas (ABG) values of a client who has chronic kidney disease. Which of the following sets of values should the nurse expect?
pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg
pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg
pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg
pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg
The Correct Answer is A
Choice A reason:
This set of values indicates metabolic acidosis, which is common in chronic kidney disease due to the accumulation of acids in the body as the kidneys fail to eliminate them effectively³.
Choice B reason:
A pH of 7.50 is considered alkalotic, and while HCO3- and PaCO2 are within normal ranges, this set of values does not typically represent chronic kidney disease.
Choice C reason:
A pH of 7.55 is also alkalotic, and an HCO3- of 30 mEq/L indicates metabolic alkalosis, which is not characteristic of chronic kidney disease.
Choice D reason:
While a pH of 7.30 is on the lower end of the normal range, an HCO3- of 26 mEq/L is within the normal range, and a PaCO2 of 50 mm Hg indicates respiratory acidosis, not typically seen in chronic kidney disease without concurrent respiratory issues.

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.
Correct Answer is ["A","B","C","E","F"]
Explanation
Choice A: Shortness of breath Shortness of breath can occur with a TAA due to the aneurysm compressing the trachea or the lung tissue. As the aneurysm enlarges, it can impinge on respiratory structures, leading to difficulty in breathing. A thoracic aortic aneurysm (TAA) is a bulging or dilation in the wall of the aorta as it passes through the chest cavity. TAAs can be life-threatening if they rupture or dissect and are often difficult to detect because they tend to grow slowly and usually do not cause symptoms until they become large or rupture.
Choice B: Difficulty swallowing Difficulty swallowing, or dysphagia, may be experienced if a TAA exerts pressure on the esophagus. This can happen when the aneurysm is located in the aortic arch, where the esophagus is in close proximity.
Choice C: Upper chest pain Upper chest pain is a common symptom of TAA and may be described as a deep, steady pain that can radiate to the back, neck, or jaw. The pain is caused by the stretching of the aortic wall and may be a warning sign of an impending rupture.
Choice D: Diaphoresis Diaphoresis, or excessive sweating, is not typically a direct symptom of a TAA. However, it can be associated with acute aortic syndromes, such as aortic dissection or rupture, which are medical emergencies.
Choice E: Cough A persistent cough can be a sign of a TAA, especially if the aneurysm is pressing against the trachea or bronchial tubes. The cough may sometimes produce blood if the aneurysm is causing erosion into these structures.
Choice F: Hoarseness Hoarseness can result from a TAA if the aneurysm compresses the recurrent laryngeal nerve, which controls the muscles of the voice box. This is known as Ortner’s syndrome or cardiovocal syndrome.
