A nurse is providing teaching for a client who is preparing for a below-the-knee amputation. Which of the following statements is true regarding the postoperative placement of a prosthesis?

Choice A reason:
This choice suggests a pH of 7.50, which is indicative of alkalosis, and not typically expected in a client with chronic kidney disease (CKD). CKD often leads to metabolic acidosis due to the accumulation of acids in the body as the kidneys fail to excrete them. The HCO₃⁻ level of 20 mEq/L is slightly lower than the normal range (22-26 mEq/L), and the PaCO₂ of 32 mm Hg is within the normal range (35-45 mm Hg), but these values do not align with the expected acidosis associated with CKD.

Choice B reason:
This set of values is consistent with metabolic acidosis, which is commonly seen in clients with CKD. A pH of 7.25 indicates acidemia, and an HCO₃⁻ level of 19 mEq/L is below the normal range, suggesting a primary metabolic acidosis. The PaCO₂ of 30 mm Hg is at the lower end of the normal range, which may indicate a compensatory respiratory response to the metabolic acidosis.

Choice C reason:
A pH of 7.30, while on the lower side, is not as acidic as one would expect in a client with CKD. The HCO₃⁻ level of 26 mEq/L is within the normal range, and a PaCO₂ of 50 mm Hg suggests respiratory acidosis, which is not the primary disorder in CKD.

Choice D reason:
This choice indicates a pH of 7.55, which is too alkaline and not characteristic of CKD, where metabolic acidosis is the expected finding. An HCO₃⁻ level of 30 mEq/L is higher than the normal range, suggesting metabolic alkalosis. The PaCO₂ of 31 mm Hg is slightly below the normal range, possibly indicating a compensatory response, but it does not align with the metabolic acidosis typically seen in CKD.

Choice A reason: An elevated oral temperature of 38.2°C (100.76°F) postoperatively can indicate an infection, which is a common complication after surgical procedures. In the context of TURP, a fever could suggest a urinary tract infection or sepsis, especially if accompanied by other symptoms such as chills or an elevated white blood cell count.

Choice B reason: The output of burgundy-colored urine can be expected in the immediate postoperative period following a TURP due to bleeding. However, it should gradually lighten in color. Persistent or worsening hematuria could indicate a complication, but it is not uncommon to see some blood in the urine shortly after the procedure

Choice C reason: A pulse rate of 88/min is within the normal range (60-100 beats per minute) and is not typically indicative of a postoperative complication. It is important to consider the patient's baseline heart rate and any other symptoms they may be experiencing.

Choice D reason: Feeling an urge to void despite having an indwelling urinary catheter can occur due to bladder spasms or irritation from the catheter itself. While uncomfortable, this sensation is not uncommon after TURP and does not necessarily indicate a complication.
