A nurse is checking the laboratory tests for a client who has glomerulonephritis. The nurse should expect to find an increase in which of the following test results?
Specific gravity
Creatinine clearance
BUN and serum creatinine
RBC
The Correct Answer is C
Choice a reason: Specific gravity measures the concentration of solutes in the urine. In glomerulonephritis, urine may be more dilute due to the kidneys' inability to concentrate urine properly, leading to a decrease rather than an increase in specific gravity.
Choice b reason: Creatinine clearance is a measure of the rate at which creatinine is cleared from the blood by the kidneys. In glomerulonephritis, kidney function is impaired, resulting in decreased creatinine clearance. Therefore, an increase in creatinine clearance is not expected in this condition.
Choice c reason: BUN (blood urea nitrogen) and serum creatinine are waste products filtered out of the blood by the kidneys. In glomerulonephritis, the kidneys' filtering capability is compromised, leading to the accumulation of these waste products in the blood. Hence, an increase in BUN and serum creatinine levels is expected in clients with glomerulonephritis, indicating reduced kidney function.
Choice d reason: RBC (red blood cell) count in the blood is not typically affected by glomerulonephritis. However, microscopic hematuria (the presence of red blood cells in urine) is a common finding in glomerulonephritis, indicating damage to the glomeruli. The RBC count in the blood itself is not expected to increase as a result of glomerulonephritis.

Correct Answer is A
Explanation
Choice a reason: The patient uses clean technique when instilling the dialysate is incorrect and requires additional teaching. Peritoneal dialysis requires sterile technique to prevent infection. Using a clean technique, which is less rigorous than sterile technique, increases the risk of introducing pathogens into the peritoneal cavity. Proper sterile technique involves meticulous hand hygiene, using sterile gloves, and ensuring all equipment and supplies are sterile.
Choice b reason: The patient performs exchanges on a table with a sterile drape is appropriate. Using a sterile drape helps maintain a sterile field and reduces the risk of contamination during the dialysis procedure. This practice is an important part of sterile technique and helps ensure the patient's safety.
Choice c reason: The patient verbally expresses symptoms to report to the HCP is a positive behavior. Being aware of and communicating symptoms that may indicate complications, such as signs of infection or peritonitis, is crucial for timely intervention and management. This practice shows the patient is knowledgeable about monitoring their health and knowing when to seek professional help.
Choice d reason: The patient washes their hands before beginning is an essential step in both clean and sterile techniques. Proper hand hygiene is critical in preventing the spread of infection and is a fundamental practice in peritoneal dialysis. Washing hands thoroughly before starting the procedure helps minimize the risk of contamination.
Correct Answer is D
Explanation
Choice a reason: White rice is not a significant source of potassium. While it provides carbohydrates and some vitamins, it does not help to increase potassium levels, which is crucial for a client taking furosemide, a diuretic that can cause potassium depletion.
Choice b reason: Cheddar cheese, while nutritious, is also low in potassium. It provides calcium and protein but does not significantly contribute to increasing potassium levels. For clients needing to boost their potassium intake, other foods rich in potassium are more appropriate.
Choice c reason: Cabbage, although a healthy vegetable, is not high in potassium. It offers vitamins and fiber but does not provide the necessary potassium levels needed for someone with a low serum potassium level. Hence, it is not the best option for this client's dietary needs.
Choice d reason: Bananas are an excellent source of potassium and are recommended for clients with low potassium levels. Furosemide can deplete potassium, and bananas can help replenish this essential mineral. Including bananas in the client's daily diet is effective in maintaining appropriate potassium levels.
