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
While having extra pillows can help with comfort, it does not address the primary safety concern associated with ascites, which is the risk of falls due to altered center of gravity and balance.
Choice B rationale
The advice about undergarments is not a safety precaution but rather a comfort consideration. It is less critical than ensuring the client's safety while ambulating.
Choice C rationale
This is the correct choice because it directly addresses a significant safety risk for the client. Ascites can greatly affect balance, increasing the risk of falls, which can lead to serious injury, especially in older adults.
Choice D rationale
While exercise is important, this statement is overly restrictive and not accurate. Clients with ascites can often still engage in exercise, albeit modified, to accommodate their condition and under medical supervision.
Correct Answer is A
Explanation
Choice A rationale
Diarrhea is a common symptom in both ulcerative colitis (UC) and Crohn's disease, often presenting with urgency and frequency.
Choice B rationale
Lesions that penetrate the intestine are more characteristic of Crohn's disease, which can affect any layer of the intestinal wall and any part of the gastrointestinal tract.
Choice C rationale
Strictures are more common in Crohn's disease due to its transmural inflammatory nature, which can lead to fibrosis and narrowing of the intestines¹.
Choice D rationale
UC is restricted to the colon and often involves the rectum, but Crohn's disease can affect any part of the gastrointestinal tract from the mouth to the anus and is not restricted to the rectum¹.
