A nurse is caring for a client who is receiving diazepam as conscious sedation for an endoscopy, Which of the following antidotes should the nurse have on hand during the procedure?

A. Lorazepam 2.5mg PO qhs before bed: This transcription suggests a fixed dose to be taken before bed (qhs = every bedtime), which does not align with the "as needed" or PRN (pro re nata) instruction for anxiety.

B. Lorazepam 2.5 mg PO QD at hs: This suggests that the medication should be taken once daily (QD) at bedtime (hs = at hour of sleep), which again is not appropriate for as-needed (PRN) use in anxiety.

C. Lorazepam 2.5 mg PO every 8 hours as needed for anxiety: This transcription correctly indicates that the lorazepam is to be taken as needed for anxiety, with a dose of 2.5 mg. However, this also suggests it can be taken every 8 hours, which is more of a standard timing than PRN use. But, it is still the most accurate option for a PRN order.

D. Lorazepam 2.50 mg PO Q 8 hours for anxiety:This prescription is incorrect because it implies the medication should be taken every 8 hours regardless of need, which conflicts with the as-needed (PRN) nature of the order.

The nurse should report to the provider that the client is taking ginkgo biloba. Ginkgo biloba is an herbal supplement that can interact with clopidogrel and other antiplatelet medications. It may increase the risk of bleeding when taken concurrently with clopidogrel, which is an antiplatelet medication used to prevent blood clots after coronary artery stenting.

Let's go through the other options:

A. The client is taking acetaminophen: Acetaminophen is not known to have significant interactions with clopidogrel. It is a commonly used pain reliever and fever reducer and does not usually affect the antiplatelet activity of clopidogrel.

B. The client is taking valerian: Valerian is an herbal supplement often used as a sleep aid or to reduce anxiety. While there is limited evidence of significant interactions with clopidogrel, it is generally recommended to use caution when combining valerian with antiplatelet medications. However, it is not as concerning as ginkgo biloba in terms of potential bleeding risk.

C. The client is taking vitamin B6: Vitamin B6 is a water-soluble vitamin and is not expected to have significant interactions with clopidogrel. It is generally considered safe to use vitamin B6 with antiplatelet medications like clopidogrel.
