Final answer:
The 'CR' in zolpidem CR stands for 'controlled release,' referring to its design to release the medication slowly over time to help a person maintain sleep throughout the night.
Step-by-step explanation:
The term CR in zolpidem CR stands for controlled release. This means that the medication is designed to release the active ingredient gradually over time to provide a longer duration of effect, which can help to maintain sleep throughout the night. Controlled release formulations are appropriate for conditions where a steady level of medication is beneficial, like in the management of sleep disorders.
In the case of zolpidem, a commonly prescribed sleep aid, the controlled release formulation ensures that the person does not only fall asleep but stays asleep by releasing the medication slowly. It's ideal for patients who have difficulties staying asleep as well as falling asleep. The nurse should explain that while zolpidem CR will help to improve the quality of sleep by allowing for longer periods of uninterrupted sleep, it is still essential to follow good sleep hygiene practices for optimal results.
