A nurse is reviewing the BUN and creatinine levels of an older adult patient with chronic kidney disease. The nurse should anticipate which of the following findings?
BUN 8 mg/dL and creatinine 0.7 mg/dL
BUN 45 mg/dL and creatinine 8 mg/dL
BUN 23 mg/dL and creatinine 1.0 mg/dL
BUN 10 mg/dL and creatinine 0.3 mg/dL
The Correct Answer is B
Choice A reason:
A BUN level of 8 mg/dL and a creatinine level of 0.7 mg/dL are within normal ranges for a healthy individual without kidney disease. In chronic kidney disease (CKD), we would expect these values to be elevated due to the kidneys' reduced ability to filter waste products from the blood.
Choice B reason:
A BUN level of 45 mg/dL and a creatinine level of 8 mg/dL are significantly higher than the normal range, which is consistent with impaired kidney function seen in CKD. These elevated levels indicate that the kidneys are not effectively filtering urea and creatinine from the blood, leading to their accumulation.
Choice C reason:
A BUN level of 23 mg/dL and a creatinine level of 1.0 mg/dL could be seen in the early stages of CKD. While the creatinine level is within the normal range, the BUN level is slightly elevated, which may suggest a decline in kidney function.
Choice D reason:
A BUN level of 10 mg/dL and a creatinine level of 0.3 mg/dL are both below the normal range. This is an unlikely finding for a patient with CKD, as kidney impairment typically leads to increased levels of these substances in the blood.

Correct Answer is ["B","C","E"]
Explanation
Choice A reason:
Increased hematocrit levels are not typically associated with fluid overload. In fact, hematocrit may decrease in fluid overload due to hemodilution, where the volume of plasma increases, diluting the concentration of red blood cells.
Choice B reason:
An increased respiratory rate can be a sign of fluid overload. As fluid accumulates in the body, it can lead to pulmonary edema, which is the buildup of fluid in the lung's air sacs. This can impair gas exchange and lead to increased respiratory rate as the body attempts to compensate for reduced oxygenation.
Choice C reason:
Increased blood pressure is a common finding in fluid overload. As the volume of fluid in the bloodstream increases, it can lead to higher blood pressure due to the extra fluid that the heart must pump and the increased resistance in the blood vessels.
Choice D reason:
Increased temperature is not a direct finding associated with fluid overload. While fever may indicate an infection or other conditions, it is not specifically related to the volume of fluid in the body.
Choice E reason:
An increased heart rate may occur in fluid overload as the heart works harder to pump the excess volume of blood through the body. This compensatory mechanism aims to maintain adequate circulation and blood pressure despite the increased fluid volume.
Correct Answer is B
Explanation
Choice A reason:
Resuming a regular diet immediately after the test may not always be recommended. Depending on the individual's condition and the specific instructions from the healthcare provider, there may be dietary restrictions before or after the procedure.
Choice B reason:
Encouraging fluid intake after the procedure is important because it helps to flush out the contrast dye used during the IVP. Adequate hydration can aid in the elimination of the dye and reduce the risk of kidney damage, especially in individuals with pre-existing kidney conditions.
Choice C reason:
This statement is incorrect. An IVP does not use high-frequency sound waves; it involves taking X-ray images of the urinary tract after a contrast dye is injected into a vein. The dye outlines the kidneys, ureters, and bladder on the X-ray images.
Choice D reason:
The presence of red blood cells in the urinalysis does not typically result in the cancellation of an IVP. However, certain conditions, such as an allergy to the contrast dye or severe kidney impairment, may contraindicate the use of an IVP.
