A nurse is caring for a school-age child who has diabetes mellitus. Which of the following findings should the nurse recognize as being consistent with hyperglycemia?

A. Bradycardia: Bradycardia (a slow heart rate) is not typically associated with heart failure. Heart failure usually leads to increased heart rate (tachycardia) as the heart attempts to compensate for poor cardiac output.

B. Increased appetite: Increased appetite is not commonly seen in heart failure. In fact, children with heart failure often have poor appetite and may experience difficulty eating due to fatigue and shortness of breath.

C. Tachypnea: Correct. Tachypnea is a common manifestation of heart failure as the body attempts to increase oxygen intake due to decreased cardiac output and poor perfusion.

D. Tremors: Tremors are not typically associated with heart failure. They are more commonly related to neurological or metabolic conditions.

A. Hypotension: Hypotension is not a common adverse effect of cefazolin. While severe allergic reactions can cause hypotension, it is not a typical side effect to monitor for with cefazolin specifically.

B. Stevens-Johnson syndrome: Correct. Stevens-Johnson syndrome (SJS) is a rare but serious adverse effect of many antibiotics, including cefazolin. SJS is a severe skin reaction that requires immediate medical attention.

C. Prolonged wound healing: Cefazolin is an antibiotic and would not typically cause prolonged wound healing; instead, it is used to prevent or treat infections that might impair healing.

D. Bradypnea: Bradypnea is not associated with cefazolin. Respiratory depression is not a common side effect of this antibiotic.
