A nurse is educating a client who has been prescribed Buspirone for generalized anxiety disorder. Which of the following statements by the client indicates a correct understanding of the medication?
"I will need to take this medication for several weeks before noticing its full effects."
"If I don't feel better after one week, I will stop taking the medication."
"I should feel less anxious within an hour of taking the first dose."
"I can use this medication as needed when I feel a panic attack coming on."
The Correct Answer is A
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.

Correct Answer is D
Explanation
A. Take Cholestyramine with other medications to improve absorption: Cholestyramine binds bile acids in the intestine but can also bind and interfere with the absorption of other oral medications. Taking it with other drugs reduces their effectiveness and is not recommended.
B. Take the powder for oral suspension in dry form: Cholestyramine powder should never be taken dry as it can irritate the mouth, throat, and gastrointestinal tract. It should always be mixed with water or a non-carbonated beverage before ingestion to prevent choking or esophageal irritation.
C. Take after meals: While taking it after meals can enhance its bile acid-binding effect, this alone does not prevent drug interactions. Timing with other medications is the more critical issue to address when instructing patients.
D. Take other medications at least 1 hour before or 4 hours after taking Cholestyramine: This instruction is essential to avoid interference with the absorption of other oral medications. Cholestyramine can bind many drugs, so proper spacing is required to ensure therapeutic efficacy of concurrent medications.
Correct Answer is ["2"]
Explanation
Desired dose rate = 0.6 mg/hr
Available concentration = 50 mg / 150 mL
- Calculate the concentration in mg/mL:
Concentration (mg/mL) = 50 mg / 150 mL
= 1/3 mg/mL
- Calculate the flow rate in mL/hr:
Flow rate (mL/hr) = Desired dose rate (mg/hr) / Concentration (mg/mL)
= 0.6 mg/hr / (1/3 mg/mL)
= 0.6 × 3 mL/hr
Flow rate (mL/hr) = 1.8 mL/hr
- Round to the nearest whole number:
= 2 mL/hr
