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 B
Explanation
Choice A rationale
A history of high blood pressure is a risk factor for chronic kidney disease but not specifically for acute glomerulonephritis. Acute glomerulonephritis is more commonly associated with infections.
Choice B rationale
A recent sore throat and fever, especially if caused by a streptococcal infection, can lead to post-streptococcal glomerulonephritis. This is a well-documented cause of acute glomerulonephritis, making it the correct answer.
Choice C rationale
While bladder infections can lead to urinary tract infections, they are not typically associated with acute glomerulonephritis. This condition is more commonly related to infections that can cause a systemic immune response.
Choice D rationale
A history of kidney stones is associated with chronic kidney issues and can lead to infections, but it is not a direct cause of acute glomerulonephritis. This condition is usually caused by an immune response to an infection elsewhere in the body.
Correct Answer is ["A","B","D"]
Explanation
Choice A rationale
Smoking is a well-established risk factor for colorectal cancer. The carcinogens in tobacco smoke can lead to the formation of cancerous cells in the colon and rectum.
Choice B rationale
Obesity increases the risk of colorectal cancer, possibly due to chronic low-level inflammation associated with excess body fat, which can contribute to cancer development.
Choice C rationale
Limiting alcohol intake to less than four drinks per week is actually a protective measure against colorectal cancer, not a risk factor.
Choice D rationale
A high intake of red meat, particularly more than seven servings per week, has been linked to an increased risk of colorectal cancer due to compounds formed during digestion that can damage the lining of the colon and rectum.
Choice E rationale
A diet high in fruits, vegetables, and grains is generally considered protective against colorectal cancer due to the fiber and nutrients they provide, not a risk factor.
