A nurse is collecting data from a client who has systemic lupus erythematosus (SLE). Which of the following laboratory values should the nurse review to determine the client's renalfunction?

C-reactive protein

Serum creatinine

Antinuclear antibody

Erythrocyte sedimentation rate

Answer and Explanation

The Correct Answer is B

a. C-reactive protein: This is a marker of inflammation and is not specific to renal function. It is more commonly used to assess inflammation in various conditions.

b. Serum creatinine: Elevated levels of serum creatinine are indicative of impaired renal

function. Creatinine is a waste product that is normally filtered by the kidneys. Increased levels suggest decreased renal filtration.

c. Antinuclear antibody: This test is used to diagnose autoimmune diseases like SLE but does not directly measure renal function.

d. Erythrocyte sedimentation rate: This is a nonspecific marker of inflammation and is not directly related to renal function.

Correct Answer is A

Explanation

a. Restrict oral fluids to 800 to 1,000 mL/day: Hyponatremia is a characteristic finding in SIADH, and fluid restriction is a key intervention to correct the imbalance.

b. Maintain an IV of 0.45% sodium chloride: Infusing hypertonic (3%) saline may be indicated in severe cases of hyponatremia, but the initial step is fluid restriction.

c. Ensure the client receives a 2 g/day sodium diet: Dietary sodium restriction is not the primary intervention for SIADH. Fluid restriction is more critical.

d. Administer desmopressin acetate 0.2 mg orally: Desmopressin acetate is an antidiuretic

hormone and would exacerbate the retention of water, further decreasing sodium levels. It is not the appropriate intervention for this client.

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.
