A. "I will need to take this medication for several weeks before noticing its full effects.": Buspirone is an anxiolytic that works by modulating serotonin and dopamine receptors. Unlike benzodiazepines, it has a delayed onset of action, typically requiring 2–4 weeks of consistent use to achieve its full therapeutic benefit.
B. "If I don't feel better after one week, I will stop taking the medication.": Stopping Buspirone prematurely can prevent the medication from reaching its full effect. It requires patient adherence and time for therapeutic levels to build; discontinuation should only be under a provider’s guidance.
C. "I should feel less anxious within an hour of taking the first dose.": Buspirone does not provide immediate relief of anxiety symptoms. It is not effective for acute anxiety or panic attacks due to its slow onset and gradual buildup in the system.
D. "I can use this medication as needed when I feel a panic attack coming on.": Buspirone is not intended for PRN (as-needed) use. It must be taken on a scheduled basis to maintain steady blood levels and is not useful for rapid symptom relief in panic situations.

A. Flush the IV line with normal saline before and after administering phenytoin: Phenytoin is incompatible with dextrose and many other IV solutions. Normal saline is the only recommended diluent, and flushing before and after administration prevents precipitation and line blockage, ensuring safe delivery of the drug.
B. Flush the IV line with dextrose solution before and after giving phenytoin: Phenytoin precipitates in dextrose-containing solutions, which can result in crystal formation, risking embolism or phlebitis. Using dextrose can lead to serious IV complications and must be avoided.
C. Mix phenytoin with lactated Ringer's solution for infusion: Phenytoin is not compatible with lactated Ringer’s due to the calcium content, which increases the risk of precipitation. It should only be diluted in normal saline to maintain solution stability and patient safety.
D. Administer phenytoin without flushing the IV line: Skipping the flush increases the risk of drug incompatibility, precipitation, and reduced drug delivery. Flushing with normal saline is essential to maintain IV line patency and prevent complications.
