A nurse is reviewing the laboratory test results from a client who has prerenal acute kidney injury (AKI). Which of the following electrolyte imbalances should the nurse expect?
Hyperkalemia
Hypernatremia
Hypercalcemia
Hypophosphatemia
The Correct Answer is A
Choice A rationale
In prerenal AKI, the kidneys are not receiving enough blood flow. As a result, they cannot filter potassium out of the blood efficiently, leading to hyperkalemia, which is an elevated level of potassium in the blood. This condition is dangerous because it can cause cardiac dysrhythmias and muscle weakness.
Choice B rationale
Hypernatremia, an elevated sodium level, is not typically associated with prerenal AKI. It is more commonly related to dehydration or an excessive intake of sodium, which are not direct consequences of prerenal AKI.
Choice C rationale
Hypercalcemia, an elevated calcium level, is also not a common finding in prerenal AKI. It is usually associated with other conditions such as hyperparathyroidism or malignancy.
Choice D rationale
Hypophosphatemia, a low level of phosphate in the blood, is not a typical result of prerenal AKI. It can occur due to malnutrition or malabsorption, but it is not directly caused by prerenal AKI.

Correct Answer is C
Explanation
Choice A rationale
Hemorrhage refers to bleeding, which can be a serious complication of peptic ulcer disease but does not lead to the spilling of gastric contents into the peritoneal cavity.
Choice B rationale
Dumping syndrome is a condition where food moves too quickly from the stomach to the small intestine, which can cause symptoms like nausea and abdominal pain, but it does not involve the leakage of gastric contents into the peritoneal cavity.
Choice C rationale
Perforation is the correct answer because it describes a hole forming in the wall of the stomach or duodenum, allowing gastric contents to spill into the peritoneal cavity, leading to peritonitis, which is a severe and life-threatening condition.
Choice D rationale
Gastric outlet obstruction is a blockage at the end of the stomach that prevents contents from entering the small intestine, which can cause vomiting and abdominal pain, but it does not result in the leakage of gastric contents into the peritoneal cavity.
Correct Answer is A
Explanation
Choice A rationale
Liver cirrhosis is the most common cause of esophageal varices and portal hypertension. Cirrhosis leads to scarring of the liver, which impedes blood flow through the portal vein, causing increased pressure (portal hypertension) and the development of collateral blood vessels (varices) as the body attempts to bypass the blockage.
Choice B rationale
Throat lacerations are not related to the development of esophageal varices or portal hypertension. They are typically acute injuries and do not cause the chronic changes seen in the vasculature associated with these conditions.
Choice C rationale
Kyphosis, a curvature of the spine, does not cause esophageal varices or portal hypertension. It is a structural skeletal condition and does not affect the vasculature of the esophagus or the portal venous system.
Choice D rationale
While squamous cell cancer can occur in the esophagus, it is not a typical cause of portal hypertension or esophageal varices. These varices are usually a result of increased pressure in the portal vein, not directly from a malignancy.
