A patient with a respiratory infection asks the nurse why some antibiotics are prescribed to be given every 12 hours while others have to be taken 4 times per day. What is the nurse's best response?
"Regular doses are given based on the half life of the medication to maintain a therapeutic effect"
"We try to give the next dose of medication only after the last dose is gone"
"The time between medication varies to fit the nurse's schedule"
"We need to vary the times of administration to keep the blood levels fluctuating"
The Correct Answer is A
A. Dosing schedules are based on the medication's half-life to maintain a consistent therapeutic level in the bloodstream.
B. Medications are dosed at intervals to maintain therapeutic levels, not just after the last dose is gone.
C. Dosing schedules are determined by pharmacokinetics, not nurse convenience.
D. Consistent blood levels are usually desired for antibiotics, not fluctuating levels.
