Answer:
A diagnosis of cancer was made in 10.5% of nodules measuring 1 – 1.9 cm. The risk of cancer increased to 15% of nodules greater than 2 cm. In nodules that were larger than this 2 cm threshold, the cancer risk was unchanged.

Answer: a. maxillary sinuses only (but see explanation below).
Explanation:
Maxillary and sphenoid paranasal sinuses are present since birth, and may thus be a source of clinical symptoms at any age. Frontal sinuses, in contrast, do not normally become aerated until age 6. Note that, unlike maxillary and frontal sinuses, the sphenoid sinuses are located deep within the facial skeleton and may not be palpated.
A child who underwent submersion injury needs to be taken to a hospital because the child can suffer from <u>hypoxia, damage to neurons, pulmonary edema, further complications</u>, etc.
Submersion Injury
Submersion injury occurs when the person who is submerged in a liquid aspirates the liquid or has laryngospasm that occurs without the aspiration of the liquid. The former was previously called wet drowning and the latter was called dry drowning. The person must be removed from the liquid as fast as possible and 1st aid must be given after which the person must be taken to the hospital for further treatment.
A child who underwent submersion injury needs to be admitted to a hospital as various complications such as edema, respiratory compromise, hypoxia, etc. Hypoxia can lead to severe damage to various cells including neurons and other cells in the body. Submersion injury also results in the reflex inspiration that can lead to pulmonary edema.
Note: - The question seems incomplete and the missing options could be
- "Hypoxia can cause global cell damage.
- Neurons often sustain irreversible damage.
- Complications can occur even after 24 hours.
- Fluid absorption in the pulmonary circulation causes pulmonary edema."
