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 reason: wrong because applying cool compresses for 20 minutes every hour is not typically recommended.While cool compresses can help reduce joint swelling and pain, they are usually recommended to be applied for short periods and not as frequently as every hour
Choice B reason: wrong because while rest is important, there is no specific recommendation for a 45-minute nap daily.Adequate rest should be balanced with physical activity, which is essential for maintaining joint function and muscle strength
Choice C reason: wrong because allowing the child to stay at home on days when her joints are painful may lead to prolonged inactivity, which can worsen joint stiffness and reduce muscle strength.It’s important to encourage regular movement and activity as tolerated
Choice D reason: This is correct because prednisone is a corticosteroid used to reduce inflammation in conditions like juvenile idiopathic arthritis, and an alternate-day schedule can be effective in managing symptoms while minimizing side effects
Correct Answer is ["260"]
Explanation
Sure, let’s calculate the total fluid intake step by step.
Step 1: Convert ½ cup of juice to mL.
- 1 cup = 240 mL
- ½ cup = 240 mL ÷ 2 = 120 mL
- Result: 120 mL
Step 2: Convert 3 oz of gelatin to mL.
- 1 oz = 30 mL
- 3 oz = 3 × 30 mL = 90 mL
- Result: 90 mL
Step 3: Convert 1 oz of an ice pop to mL.
- 1 oz = 30 mL
- 1 oz = 30 mL
- Result: 30 mL
Step 4: Ginger ale is already in mL.
- Result: 20 mL
Step 5: Add all the mL values together.
- 120 mL (juice) + 90 mL (gelatin) + 30 mL (ice pop) + 20 mL (ginger ale) = 260 mL
- Result: 260 mL
The nurse should record the child’s fluid intake as 260 mL.
