A nurse is caring for a toddler whose parent states that while bathing the child, she noticed a mass in his abdominal area and that his urine is a pink color. Which of the following actions is the nurse's priority?

Choice A reason: Bleeding precaution is indicated for a child who has leukemia and a critically low platelet count, as it reduces the risk of hemorrhage and injury. The nurse should monitor the child for signs of bleeding, such as petechiae, ecchymosis, epistaxis, hematuria, and melena. The nurse should also avoid invasive procedures, use soft-bristled toothbrushes, apply pressure to venipuncture sites, and administer platelet transfusions as prescribed.

Choice B reason: Droplet precaution is not indicated for a child who has leukemia and a critically low platelet count, unless the child has a respiratory infection that is transmitted by droplets. Droplet precaution involves wearing a mask when within 3 feet of the child, and placing the child in a private room or with a roommate who has the same infection.

Choice C reason: Neutropenic precaution is indicated for a child who has leukemia and a critically low neutrophil count, as it reduces the risk of infection and sepsis. Neutropenic precaution involves placing the child in a private room with positive pressure airflow, wearing gloves, gown, and mask when entering the room, and restricting visitors who are ill or immunocompromised.

Choice D reason: Contact precaution is not indicated for a child who has leukemia and a critically low platelet count, unless the child has a skin or wound infection that is transmitted by direct or indirect contact. Contact precaution involves wearing gloves and gown when entering the room, and placing the child in a private room or with a roommate who has the same infection.

Choice A reason: This test will confirm if your child had a recent streptococcal infection, as it measures the level of antibodies that the body produces against the streptolysin O enzyme, which is produced by some strains of streptococcal bacteria. A high ASO titer indicates a recent or current streptococcal infection, which can trigger rheumatic fever in some children.

Choice B reason: This test will not indicate if your child has rheumatic fever, as it does not measure the inflammation or damage to the heart, joints, or other organs that rheumatic fever can cause. Rheumatic fever is diagnosed based on the presence of two major or one major and two minor criteria, as well as evidence of a preceding streptococcal infection.

Choice C reason: This test will not indicate if your child has a therapeutic blood level of an aminoglycoside, as it does not measure the concentration of this type of antibiotic in the blood. Aminoglycosides are used to treat serious infections caused by gram-negative bacteria, and their blood levels need to be monitored to prevent toxicity and ensure efficacy.

Choice D reason: This test will not confirm if your child has immunity to streptococcal bacteria, as it does not measure the level of protective antibodies that can prevent future infections. ASO antibodies are not protective, but rather indicate a past or present exposure to streptococcal bacteria.
