What is the characteristic of dishonest behavior in children ages 8 to 10 years?

Choice A rationale:

Calcium carbonate is often given with meals to individuals with chronic renal disease, especially those on dialysis. One of the primary purposes is to bind dietary phosphorus in the gastrointestinal tract. In chronic renal disease, the kidneys are less effective at filtering out excess phosphorus from the blood, leading to elevated phosphorus levels (hyperphosphatemia). Elevated phosphorus levels can contribute to bone and mineral disorders in these patients. Calcium carbonate forms insoluble calcium phosphate complexes with dietary phosphorus, preventing its absorption and facilitating its elimination from the body through the feces.

Choice B rationale:

While calcium carbonate can interact with fat-soluble vitamins like vitamin D, the primary reason for administering it to individuals with chronic renal disease is to manage phosphorus levels. Calcium carbonate can bind phosphorus and prevent its absorption, which is particularly important for patients with compromised kidney function.

Choice C rationale:

Stimulating appetite is not a primary purpose of administering calcium carbonate to children with chronic renal disease. The main focus is on managing phosphorus levels and preventing complications associated with hyperphosphatemia.

Choice D rationale:

Preventing vomiting is not a primary purpose of giving calcium carbonate to children with chronic renal disease. Calcium carbonate is typically used to manage phosphorus levels and complications related to hyperphosphatemia in this population.

The correct answer is choice B. A feeling of fullness in the ear.

Choice A rationale:

Nausea and vomiting are not typical symptoms of chronic otitis media with effusion (OME). OME involves fluid accumulation in the middle ear without signs of acute infection. It is commonly seen in children and may cause mild hearing impairment and a feeling of fullness in the ear.

Choice B rationale:

A feeling of fullness in the ear is a common symptom of OME. The fluid accumulation in the middle ear can lead to a sensation of pressure or fullness, as well as mild hearing loss. This can impact a child's ability to hear and communicate effectively.

Choice C rationale:

Severe pain in the ear is more characteristic of acute otitis media (AOM), which is an infection of the middle ear with signs of inflammation. In OME, pain is typically not a prominent symptom unless there is an underlying AOM episode.

Choice D rationale:

Fever as high as 40°C (104°F) is not a typical symptom of OME. OME is generally a chronic condition without acute signs of infection such as fever. However, if a fever is present, it might indicate a concurrent infection that needs further evaluation.
