A nurse is caring for a child who was admitted with suspected rheumatic fever. The provider prescribes an antistreptolysin O (ASO) titer. The parent asks the nurse about the purpose of the test. Which of the following responses should the nurse make?
"This test will indicate if your child has rheumatic fever."
"This test will confirm if your child had a recent streptococcal infection."
"This test will indicate if your child has a therapeutic blood level of an aminoglycoside."
"This test will confirm if your child has immunity to streptococcal bacteria."
The Correct Answer is B
Choice A: This test will not indicate if the child has rheumatic fever, as rheumatic fever is a complication of an untreated or inadequately treated streptococcal infection that affects the heart, joints, skin, and brain. Rheumatic fever is diagnosed based on clinical criteria, such as carditis, polyarthritis, chorea, erythema marginatum, and subcutaneous nodules.
Choice B: This test will confirm if the child had a recent streptococcal infection, as antistreptolysin O (ASO) is an antibody that the body produces in response to streptococcal bacteria. A high ASO titer indicates that the child was exposed to streptococcal bacteria within the past few weeks. A streptococcal infection can cause pharyngitis, tonsillitis, scarlet fever, or impetigo.
Choice C: This test will not indicate if the child has a therapeutic blood level of an aminoglycoside, as an aminoglycoside is a type of antibiotic that is used to treat serious bacterial infections. A therapeutic blood level of an aminoglycoside means that the drug is effective and safe in the body. A therapeutic blood level of an aminoglycoside is measured by a peak and trough level.
Choice D: This test will not confirm if the child has immunity to streptococcal bacteria, as immunity to streptococcal bacteria means that the body can resist or fight the infection. Immunity to streptococcal bacteria can be acquired by natural exposure or vaccination. Immunity to streptococcal bacteria is measured by an antibody titer or a skin test.

Correct Answer is A
Explanation
Choice A: Body image changes are the most common reaction for an adolescent who has scoliosis and requires surgical intervention, as scoliosis affects the appearance and shape of the spine and torso. Body image changes can lead to low self-esteem, social isolation, depression, or anxiety.
Choice B: Feelings of displacement are not the most common reaction for an adolescent who has scoliosis and requires surgical intervention, as displacement means feeling out of place or unwanted in a certain situation or environment. Feelings of displacement can occur due to hospitalization, separation from peers or family, or lack of control over one's life.
Choice C: Loss of privacy is not the most common reaction for an adolescent who has scoliosis and requires surgical intervention, as loss of privacy means having one's personal information or space exposed or invaded by others. Loss of privacy can occur due to frequent examinations, procedures, or interventions by health care providers or staff.
Choice D: Identity crisis is not the most common reaction for an adolescent who has scoliosis and requires surgical intervention, as identity crisis means having difficulty or confusion in defining one's self-concept or role in society. Identity crises can occur due to developmental changes, peer pressure, or cultural expectations.
Correct Answer is B
Explanation
Choice A: This instruction is not correct, as the child should avoid taking a tub bath for the first 3 days after a cardiac catheterization, which is a procedure that involves inserting a thin tube into a blood vessel and advancing it to the heart to diagnose or treat heart problems. Taking a tub bath can increase the risk of infection or bleeding at the insertion site, which is usually in the groin or arm. The child should take a shower instead and keep the insertion site clean and dry.
Choice B: This instruction is correct, as the child may experience some discomfort or soreness at the insertion site after a cardiac catheterization. Giving the child acetaminophen can help relieve the pain and reduce inflammation. The child should avoid taking aspirin or ibuprofen, as they can increase the risk of bleeding.
Choice C: This instruction is not correct, as the child does not need to stay home for 1 week after a cardiac catheterization unless there are complications or specific instructions from the provider. The child can resume normal activities within 2 to 3 days after the procedure, as long as they avoid strenuous exercise, heavy lifting, or contact sports.
Choice D: This instruction is not correct, as the child does not need to limit their diet to clear liquids for the first 24 hours after a cardiac catheterization unless there are complications or specific instructions from the provider. The child can resume their regular diet as soon as they feel hungry and drink plenty of fluids to flush out the contrast dye used during the procedure.
