The processes involved in dynamic equilibrium are key elements in the nurse's ability to determine what?
- A. Dosage scheduling
- B. Amount of solution for mixing parenteral drugs
- C. Timing of other drugs the patient is taking
- D. How long the patient has to take the drug
Correct Answer: A
Rationale: These processes are key elements in determining the amount of drug (dose) and the frequency of dose repetition (scheduling) required to achieve the critical concentration for the desired length of time. The processes in dynamic equilibrium are not key elements in determining the amount of diluents for intramuscular (IM) drugs; they do not aid in the timing of the other drugs the patient is taking or how long the patient has to take the drug.
