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 B
Explanation
Choice A: This information is incorrect, as the first dose of the diphtheria, tetanus, pertussis (DTaP) vaccine is usually given at 2 months of age, not 2 weeks. The DTaP vaccine protects against three serious bacterial diseases that can cause respiratory infections, nerve damage, or death. The DTaP vaccine is given in five doses at 2, 4, 6, 15 to 18 months, and 4 to 6 years of age.
Choice B: This information is correct, as the first dose of the hepatitis B vaccine is usually given within 24 hours of birth or prior to discharge from the hospital. The hepatitis B vaccine protects against a viral infection that can cause liver inflammation, cirrhosis, or cancer. The hepatitis B vaccine is given in three doses at birth, 1 to 2 months, and 6 to 18 months of age.
Choice C: This information is incorrect, as the first dose of the measles, mumps, rubella (MMR) vaccine is usually given at 12 to 15 months of age, not 6 months. The MMR vaccine protects against three viral diseases that can cause fever, rash, swelling of glands, or complications such as pneumonia, encephalitis, or deafness. The MMR vaccine is given in two doses at 12 to 15 months and 4 to 6 years of age.
Choice D: This information is incorrect, as the first dose of the pneumococcal conjugate (PCV13) vaccine is usually given at 2 months of age, not on the first birthday. The PCV13 vaccine protects against a bacterial infection that can cause pneumonia, meningitis, or sepsis. The PCV13 vaccine is given in four doses at 2, 4, 6, and 12 to 15 months of age.
Correct Answer is D
Explanation
Choice A: Restraining the child's arms is not an appropriate action for a nurse to take when caring for a child who is experiencing a seizure, as this can cause injury to the child or the nurse. Restraining the child's arms can also increase the child's anxiety and agitation, which can worsen the seizure.
Choice B: Using a padded tongue blade is not an appropriate action for a nurse to take when caring for a child who is experiencing a seizure, as this can cause injury to the child's mouth, teeth, or tongue. Using a padded tongue blade can also increase the risk of choking or aspiration, which can compromise the child's airway.
Choice C: Attempting to stop the seizure is not an appropriate action for a nurse to take when caring for a child who is experiencing a seizure, as this can be ineffective or harmful. Attempting to stop the seizure can also interfere with the natural course of the seizure, which may be necessary for the brain to recover.
Choice D: Positioning the child laterally is an appropriate action for a nurse to take when caring for a child who is experiencing a seizure, as this can help maintain the child's airway and prevent aspiration. Positioning the child laterally means placing the child on their side with their head tilted slightly forward and their mouth open.
