A nurse is reviewing the medical record of a toddler who has moderate dehydration. Which of the following findings should the nurse expect?

A. Drink eight glasses of fluid daily: Maintaining hydration is crucial in preventing sickle cell crises as it helps to keep the blood less viscous, reducing the risk of vaso-occlusion.

B. Maintain an updated haemophilus influenza type B immunization: While staying up to date on vaccinations is important, it is not specific to preventing sickle cell crises.

C. Assume postural drainage positions every 6 hr: This is more relevant for respiratory conditions like cystic fibrosis, not sickle cell anemia.

D. Avoid playground activities at school: Regular activity is beneficial, but avoiding extreme physical exertion is more relevant. Normal playground activities can usually be continued with proper hydration and caution.

Answer: B. "I'll take this medication with a full glass of milk."

A. "I'll take this medication at least an hour before I eat a meal."
This statement indicates correct understanding. Tetracycline should ideally be taken on an empty stomach, which means taking it at least one hour before or two hours after meals to maximize absorption and effectiveness.

B. "I'll take this medication with a full glass of milk."
This statement indicates a need for further education. Tetracycline should not be taken with dairy products, including milk, because calcium in dairy can bind to the antibiotic and significantly reduce its absorption, making the medication less effective.

C. "I'll take this medication with a full glass of water on an empty stomach."
This statement demonstrates proper understanding. Tetracycline should be taken with a full glass of water and on an empty stomach to ensure optimal absorption and reduce the risk of gastrointestinal irritation.

D. "I'll stay out of direct sunlight while taking this medication."
This statement reflects correct knowledge about the medication. Tetracycline can increase sensitivity to sunlight (photosensitivity), so it is advisable for the client to avoid prolonged exposure to direct sunlight and use sunscreen to protect their skin.
