A nurse is reviewing the laboratory results of an adolescent who has diabetes mellitus. For which of the following values should the nurse notify the provider?

Choice A rationale:
Urine osmolality 500 mOsm/kg. Urine osmolality is a measure of urine concentration and is not a reliable indicator of infection. It reflects the kidney's ability to concentrate urine and can vary based on hydration status and other factors. An elevated urine osmolality could suggest dehydration, not necessarily infection.
Choice B rationale:
WBC 17,500/mm3. This is the correct choice. An elevated white blood cell count (WBC) is a hallmark sign of infection. The body's immune response to an infection often includes an increase in WBC count, particularly the neutrophil count. This elevation is known as leukocytosis and is a red flag for infection.
Choice C rationale:
BUN 12 mg/dL. Blood Urea Nitrogen (BUN) measures kidney function and hydration status. While an elevated BUN can indicate dehydration, it is not a specific marker for infection. BUN levels can be influenced by various factors, including diet and renal function.
Choice D rationale:
Urine specific gravity 1.014. Urine-specific gravity reflects the concentration of solutes in urine and the kidney's ability to concentrate or dilute urine. While changes in urine specific gravity can indicate dehydration or overhydration, it is not a direct indicator of infection. An infection is better detected through changes in WBC count and other clinical signs.

Choice A rationale:
Tinnitus is the perception of noise or ringing in the ears. It can be caused by various factors, including exposure to loud noises, ear infections, and certain medications. However, tinnitus is not a commonly reported adverse effect of albuterol, which is a bronchodilator used to treat conditions like asthma and other respiratory disorders.
Choice B rationale:
Constipation is not a commonly reported adverse effect of albuterol. Albuterol primarily acts on the smooth muscles of the airways to relax and dilate them, improving airflow. Constipation is more likely related to issues with the gastrointestinal system or certain medications, but it is not a direct consequence of albuterol use.
Choice C rationale:
Hypoglycemia, or low blood sugar, is not a known adverse effect of albuterol. Albuterol primarily affects the respiratory system and does not typically impact blood glucose levels. Hypoglycemia is more commonly associated with diabetes medications like insulin or certain oral hypoglycemic agents.
Choice D rationale:
Headache is a potential adverse effect of albuterol. While not everyone will experience a headache when taking albuterol, it can occur as a side effect in some individuals. Albuterol can stimulate the sympathetic nervous system, leading to effects such as increased heart rate and potential vasodilation, which could contribute to the development of a headache in some cases. It's important for the parents of a child taking albuterol to be aware of potential side effects and report them to the healthcare provider if they occur.
