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 D
Explanation
Choice A: This instruction is incorrect, as withholding insulin dose if feeling nauseous can cause hyperglycemia, which is high blood sugar, and diabetic ketoacidosis, which is a life-threatening condition that occurs when the body breaks down fat for energy and produces ketones. Ketones are acidic substances that can cause nausea, vomiting, abdominal pain, dehydration, or coma. The child should take their insulin dose as prescribed and monitor their blood sugar levels more frequently when they are sick.
Choice B: This instruction is unnecessary, as notifying the provider if blood glucose levels are within normal parameters does not require any action or intervention. The child and the parents should notify the provider if blood glucose levels are above or below the target range, which is usually 70 to 180 mg/dL for children with type 1 diabetes mellitus. The child and the parents should also notify the provider if they have any signs or symptoms of hypoglycemia, hyperglycemia, or diabetic ketoacidosis.
Choice C: This instruction is incorrect, as limiting fluid intake during mealtime can cause dehydration, which can worsen the symptoms and complications of type 1 diabetes mellitus. Dehydration can cause increased thirst, dry mouth, fatigue, headache, or dizziness. The child should drink plenty of fluids during meal time and throughout the day to hydrate their body and flush out excess glucose and ketones.
Choice D: This instruction is correct, as testing the urine for ketones can help detect diabetic ketoacidosis, which is a life-threatening condition that occurs when the body breaks down fat for energy and produces ketones. Ketones are acidic substances that can cause nausea, vomiting, abdominal pain, dehydration, or coma. The child should test their urine for ketones when their blood sugar levels are above 240 mg/dL or when they are sick. The child and the parents should notify the provider if the urine test shows moderate or large amounts of ketones.
Correct Answer is B
Explanation
Choice A: Cranberry juice is not a suitable fluid item to offer the child at this time, as it is acidic and can irritate the throat and cause pain or bleeding. Cranberry juice can also stain the surgical site and make it difficult to assess for signs of hemorrhage.
Choice B: Crushed ice is a suitable fluid item to offer the child at this time, as it is cold and can soothe the throat and
reduce swelling or inflammation. Crushed ice can also hydrate the child and prevent dehydration.
Choice C: Orange juice is not a suitable fluid item to offer the child at this time, as it is acidic and can irritate the throat and cause pain or bleeding. Orange juice can also interfere with the clotting process and increase the risk of hemorrhage.
Choice D: A strawberry milkshake is not a suitable fluid item to offer the child at this time, as it contains dairy products and can increase mucus production and cause coughing or gagging. A strawberry milkshake can also stain the surgical site and make it difficult to assess for signs of hemorrhage.
