A nurse is reviewing the diagnostic test results of a female client who is about to undergo knee arthroplasty. Which of the following data collection findings should the nurse identify as the priority?

Creatinine 0.9 mg/dL

WBC count 20,000/mm3

Potassium 3.8 mEq/L

Hematocrit 40%

Answer and Explanation

The Correct Answer is B

a. Creatinine 0.9 mg/dL: This creatinine level is within the normal range and is not an immediate priority for knee arthroplasty.

b. WBC count 20,000/mm3: An elevated white blood cell count suggests the presence of

infection or inflammation. In the context of knee arthroplasty, infection is a significant concern and requires immediate attention to prevent complications.

c. Potassium 3.8 mEq/L: This potassium level is within the normal range and is not an immediate priority for knee arthroplasty.

d. Hematocrit 40%: This hematocrit level is within the normal range and is not an immediate priority for knee arthroplasty. The elevated WBC count takes precedence as it suggests a

potential infectious process.

Correct Answer is C

Explanation

a. Hyperactive bowel sounds: Shock is more likely to be associated with decreased bowel sounds rather than hyperactive bowel sounds.

b. Increased urine output: In the early stages of shock, there may be an increase in urine output as the body attempts to compensate. However, as shock progresses, renal perfusion decreases,

leading to decreased urine output.

c. Hypotension: Hypotension is a key indicator of shock. In shock, there is insufficient blood flow to meet the body's oxygen and nutrient needs, resulting in a drop in blood pressure.

d. Bradycardia: Shock typically leads to an increased heart rate (tachycardia) as the body tries to compensate for decreased cardiac output. Bradycardia is not a typical finding in the early stages of shock.

A. “I will drink plenty of fluids after the test.” B. “I will expect my stool to be black after this procedure.” C. “I will expect a warm feeling when the dye is injected.” D. “I will maintain a clear liquid diet 24 hours before the test.”

Correct Answer is A

Explanation

a.The statement "I will drink plenty of fluids after the test" indicates the client's understanding that hydration is important after the procedure, which is also a crucial aspect of post-procedure care. This response suggests the client understands the need to stay hydrated after ingesting barium, which helps eliminate the contrast material from the body and prevents constipation.

b. “I will expect my stool to be black after this procedure.”: The statement is related to the potential side effects of barium, but it does not address the pre-test instructions.

c. “I will expect a warm feeling when the dye is injected.”: This statement may relate to the sensation during the test but does not address the pre-test instructions.

d.while fasting may be required before the test, a clear liquid diet is not typically maintained for 24 hours prior to the procedure.
