An intravenous (IV) antibiotic is prescribed for a client with a postoperative infection. The medication is to be administered in 4 divided doses. Which schedule is best for administering this prescription?
Administer with meals and a bedtime snack.
1000, 1600, 2200, 0400.
0800, 1200, 1600, 2000.
Give in equally divided doses during waking hours.
The Correct Answer is B
A. Timing with meals is inappropriate for IV antibiotics because it does not maintain consistent blood levels.
B. Spacing doses every 6 hours around the clock maintains therapeutic levels and is standard for a 4-times-daily IV antibiotic.
C. This schedule leaves a long gap overnight, risking subtherapeutic levels and decreased effectiveness.
D. Limiting doses to waking hours creates uneven intervals, which may compromise treatment efficacy.

Correct Answer is C
Explanation
A. Right ear hearing loss. While significant, right ear hearing loss is not immediately life- threatening.
B. Difficulty with balance. Balance issues may be concerning but are not typically indicative of a life-threatening condition.
C. Intensifying headache. An intensifying headache can be a sign of increased intracranial pressure, which is a medical emergency and requires immediate attention.
D. Facial numbness. Facial numbness can indicate nerve involvement but is not as immediately concerning as an intensifying headache, which could indicate a serious neurological issue such as bleeding or swelling in the brain.
Correct Answer is A
Explanation
A. Serum potassium. Insulin therapy causes potassium to move into cells, which can lead to hypokalemia. Monitoring serum potassium is critical because significant drops can lead to cardiac arrhythmias and other complications.
B. Urine ketones. While monitoring ketones is important for assessing the resolution of DKA, it is not as immediately critical as monitoring potassium levels.
C. Serum sodium. Sodium levels are important but typically do not change as rapidly as potassium levels during DKA treatment.
D. Blood urea nitrogen (BUN). BUN levels provide information about kidney function and hydration status but are less immediately critical than potassium levels in the context of insulin therapy for DKA.
