A nurse is providing instructions about a 24-hour urine collection to an adolescent client. Which of the following should the nurse include in the teaching?
Discard the first voided specimen.
Void every hour.
Save the final specimen in a separate container.
Cleanse the perineum with a povidone-iodine solution prior to voiding.
The Correct Answer is A
The correct answer is Choice A.
Choice A rationale
The first voided specimen is discarded to ensure that the 24-hour urine collection starts with an empty bladder and accurately reflects the urine produced over the entire period.
Choice B rationale
Voiding every hour is not necessary and may not be practical for a 24-hour urine collection.
Choice C rationale
The final specimen should be included in the same container as the rest of the 24-hour urine collection.
Choice D rationale
Cleansing the perineum with a povidone-iodine solution is not required for a 24-hour urine collection.

Correct Answer is ["A","D","E"]
Explanation
The correct answers are Choice A, Choice D, and Choice E.
Choice A rationale
Antistreptolysin O (ASO) titer is a blood test used to detect antibodies against streptolysin O, a substance produced by group A Streptococcus bacteria. Elevated ASO titers indicate a recent streptococcal infection, which is a common precursor to rheumatic fever.
Choice B rationale
Partial thromboplastin time (PTT) measures the time it takes for blood to clot and is used to evaluate bleeding disorders. It is not relevant for diagnosing rheumatic fever, which is an inflammatory disease.
Choice C rationale
Blood urea nitrogen (BUN) measures kidney function and is not used to diagnose rheumatic fever. Rheumatic fever is diagnosed based on evidence of a preceding streptococcal infection and clinical criteria.
Choice D rationale
Erythrocyte sedimentation rate (ESR) is a blood test that measures inflammation in the body. Elevated ESR levels are one of the minor criteria for diagnosing rheumatic fever, indicating the presence of inflammation.
Choice E rationale
C-reactive protein (CRP) is another marker of inflammation. Elevated CRP levels are also one of the minor criteria for diagnosing rheumatic fever, reflecting the inflammatory response in the body.
Correct Answer is B
Explanation
Choice A rationale: A hemoglobin of 6.8 g/dL is significantly below the normal range for a 4-year-old. This finding indicates ongoing anemia, which is a common complication of leukemia rather than a therapeutic response.
Choice B rationale: An RBC count of 5/mm³ falls within the normal pediatric range. In leukemia, the bone marrow is crowded with blast cells; a normal RBC count suggests the marrow is recovering and producing healthy cells.
Choice C rationale: A WBC count of 15,000/mm³ is elevated. In acute lymphoblastic leukemia, high WBC counts often represent an overabundance of immature, non-functional leukemic blast cells, suggesting the disease is still active.
Choice D rationale: A platelet count of 98,000/mm³ indicates thrombocytopenia. While common during chemotherapy, a therapeutic effect would be demonstrated by a return toward the normal range of 150,000 to 400,000/mm³.
