A nurse is caring for a 3-year-old child who was admitted with acute diarrhea and dehydration. Which of the following findings indicates that oral rehydration therapy has been effective?
Respiratory rate of 24 breaths/min
Heart rate of 130/min
Urine specific gravity of 1.015
Capillary refill of greater than 3 seconds
The Correct Answer is C
Choice A reason: A respiratory rate of 24 breaths/min is within the normal range for a 3-year-old child. It does not indicate the degree of hydration or dehydration of the child.
Choice B reason: A heart rate of 130/min is above the normal range for a 3-year-old child, which is 80 to 120/min. It may indicate dehydration, fever, pain, or anxiety. It does not indicate the effectiveness of oral rehydration therapy.
Choice C reason: A urine specific gravity of 1.015 is within the normal range for a child, which is 1.005 to 1.030. It indicates that the child's urine is adequately concentrated and that the child is well hydrated. It is a reliable indicator of the effectiveness of oral rehydration therapy.
Choice D reason: A capillary refill of greater than 3 seconds is abnormal and indicates poor peripheral perfusion. It may be a sign of dehydration, shock, or hypothermia. It does not indicate the effectiveness of oral rehydration therapy.

Correct Answer is B
Explanation
Choice A reason: Haemophilus influenzae type b (Hib) vaccine is not the correct choice, as it is usually given to children at 2, 4, 6, and 12 to 15 months of age. A 4-year-old child should have already completed the Hib vaccine series.
Choice B reason: Varicella (VAR) vaccine is the correct choice, as it is recommended for children at 12 to 15 months and 4 to 6 years of age. A 4-year-old child is due for the second dose of the VAR vaccine.
Choice C reason: Hepatitis B (HepB) vaccine is not the correct choice, as it is usually given to children at birth, 1 to 2 months, and 6 to 18 months of age. A 4-year-old child should have already completed the HepB vaccine series.
Choice D reason: Meningococcal (MCV4) vaccine is not the correct choice, as it is not routinely recommended for children younger than 11 years of age. MCV4 vaccine is given to children at 11 to 12 years and 16 years of age, or to children with certain high-risk conditions.
Correct Answer is A
Explanation
Choice A reason: This test 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 level of ASO titer indicates that the child had a recent streptococcal infection, which may trigger rheumatic fever in some cases.
Choice B reason: This test does not directly indicate if the child has rheumatic fever. Rheumatic fever is a complication of untreated or inadequately treated streptococcal infection, which causes inflammation of the heart, joints, skin, and brain. The diagnosis of rheumatic fever is based on clinical criteria, such as the presence of carditis, polyarthritis, chorea, erythema marginatum, or subcutaneous nodules.
Choice C reason: This test does not confirm if the child has immunity to streptococcal bacteria. Immunity is the ability of the body to resist or fight off an infection. A high level of ASO titer does not mean that the child is immune to streptococcal bacteria, but rather that the child was exposed to them recently.
Choice D reason: This test does not indicate if the child has a therapeutic blood level of an aminoglycoside. Aminoglycosides are a class of antibiotics that are used to treat serious bacterial infections, such as endocarditis or septicemia. The blood level of an aminoglycoside is measured by a different test, called a peak and trough level, which determines the effectiveness and safety of the drug.
