A nurse is caring for a child who has rheumatic fever. When obtaining the child's medical history from the parent, the nurse should recognize the significance of which of the following data as the possible source of the child's infection?
The father who had gastritis 2 weeks ago
A neighbor's child who has chickenpox
A sibling who had a sore throat 3 weeks ago
A classmate who has fifth disease
The Correct Answer is C
A. Gastritis is not an infectious condition and is unlikely to be the source of the child's rheumatic fever.
B. Chickenpox is caused by a different pathogen (varicella-zoster virus) and is not associated with the development of rheumatic fever.
C. Rheumatic fever often follows untreated or inadequately treated streptococcal infections, particularly streptococcal pharyngitis (sore throat). A sibling with a recent sore throat is a significant piece of information.
D. Fifth disease is caused by parvovirus B19 and is not known to be a precursor to rheumatic fever.

Correct Answer is C
Explanation
A. Elevated temperature in a toddler with roseola is generally self-limiting and not immediately life-threatening.
B. A urine specific gravity of 1.016 in a 7-year-old with diabetes insipidus indicates a dilute urine concentration and is not an acute priority.
C. Sickle cell anemia can lead to vaso-occlusive crises, and severe chest pain could suggest a potential life-threatening complication such as acute chest syndrome. This requires immediate attention.
D. A PCO2 level of 37 mm Hg in a 4-year-old with asthma, while indicating respiratory distress, may not be as urgently life-threatening as severe chest pain in a child with sickle cell anemia.
Correct Answer is D
Explanation
A. Administer at mealtimes is incorrect. Taking iron supplements with food can decrease absorption. It is best to take them on an empty stomach if possible, but if gastrointestinal upset occurs, the medication can be taken with food.
B. Administer at bedtime is incorrect. Iron supplements are generally not recommended to be taken at bedtime due to potential gastrointestinal upset that might disturb sleep.
C. Give with a 240 mL (8 oz) glass of milk is incorrect. Milk can reduce the absorption of iron, so it is not recommended to take ferrous sulfate with milk.
D. Give with orange juice is correct. Vitamin C (found in orange juice) enhances the absorption of iron, so it is a good choice to help increase the effectiveness of the supplement.
