A nurse is teaching a parent of an infant who has heart failure about meeting the infant's nutritional needs. Which of the following statements by the parent indicates an understanding of the teaching?
I will allow my baby to take as much time as needed to finish the bottle.
I will add Polycose to each of my baby's bottles.
I will feed my baby on a schedule every 4 hours.
I will limit my baby's crying to 15 minutes prior to each feeding.
The Correct Answer is B
The correct answer is: B. I will add Polycose to each of my baby's bottles.
Choice A reason:
Allowing the baby to take as much time as needed to finish the bottle is not ideal for infants with heart failure. These infants often tire easily and may not consume enough calories if feeding sessions are prolonged. Shorter, more frequent feedings are generally recommended to ensure adequate intake without exhausting the infant.
Choice B reason:
Adding Polycose to each bottle is an effective way to increase the caloric density of the infant's feedings. Infants with heart failure have higher caloric needs due to their increased metabolic demands and may struggle to consume enough calories through regular formula or breast milk alone. Polycose, a carbohydrate supplement, helps meet these increased nutritional needs.
Choice C reason:
Feeding the baby on a schedule every 4 hours may not be sufficient for an infant with heart failure. These infants often require more frequent feedings to meet their caloric needs and to prevent fatigue during feeding. Feeding every 1-3 hours is typically recommended to ensure they receive adequate nutrition.
Choice D reason:
Limiting the baby's crying to 15 minutes prior to each feeding does not directly address the nutritional needs of an infant with heart failure. While managing crying is important to reduce energy expenditure, the focus should be on providing adequate nutrition through frequent, high-calorie feedings.

Correct Answer is A
Explanation
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.
Correct Answer is B
Explanation
The correct answer is: b.
Choice A: Heart rate 130/min
A heart rate of 130 beats per minute (bpm) is considered high for a 3-year-old child. Normal heart rates for children aged 1-3 years typically range from 80 to 120 bpm. While dehydration can cause tachycardia (increased heart rate), a heart rate of 130 bpm does not necessarily indicate effective rehydration.
Choice B: Urine specific gravity 1.015
Urine specific gravity of 1.015 is within the normal range (1.005–1.030) for a hydrated child. Dehydration increases urine concentration (>1.020), but a normalized value like 1.015 shows that ORT has restored fluid balance. UpToDate and NIH studies (e.g., Binder et al., 2014) highlight urine specific gravity as a precise measure of hydration status, making it the strongest indicator of ORT effectiveness.
Choice C: Respiratory rate 24/min
The normal respiratory rate for a 3-year-old child is between 20 and 30 breaths per minute. A respiratory rate of 24 breaths per minute is within this normal range. While a normal respiratory rate can indicate improved hydration status, it is not the most specific indicator of effective rehydration therapy.
Choice D: Capillary refill less than 3 seconds
Capillary refill time of less than 3 seconds suggests adequate perfusion, as normal is under 2 seconds. Dehydration may prolong this time, but “less than 3 seconds” could include slightly delayed values (e.g., 2.5 seconds). UpToDate and NIH studies (e.g., Doan et al., 2010) note it as useful but less specific than urine specific gravity for confirming ORT effectiveness.
