The nurse is caring for a child with suspected diabetes insipidus. Which clinical manifestation would be observable?

Chronic otitis media with effusion (OME) is a condition where fluid accumulates in the middle ear without signs of infection.

This can cause hearing loss, speech delay, and balance problems. The child may complain of a feeling of fullness or pressure in the ear.

Choice A is wrong because a fever as high as 40° C (104° F) is a sign of acute otitis media, which is an infection of the middle ear with inflammation and pus formation.

Choice B is wrong because severe pain in the ear is also a sign of acute otitis media, not chronic otitis media with effusion.

Choice C is wrong because nausea and vomiting are not typical symptoms of chronic otitis media with effusion. They may be associated with other conditions such as gastroenteritis or vestibular disorders.

Diabetes insipidus is a disorder of the posterior pituitary gland that causes a deficiency of antidiuretic hormone (ADH). This leads to excessive urination (polyuria) and excessive thirst (polydipsia) as the body tries to balance the fluid loss. These symptoms may be so severe that the child does little other than drink and urinate.

Choice A is wrong because oliguria means decreased urine production and is not associated with diabetes insipidus.

Choice B is wrong because glycosuria means glucose in the urine and is associated with diabetes mellitus, not diabetes insipidus.

Choice C is wrong because nausea and vomiting are associated with inappropriate ADH secretion (SIADH), which causes fluid retention and hyponatremia, not diabetes insipidus.
