A patient weighing 132 lb is prescribed lorazepam 44 mcg/kg IV to be administered 20 minutes before a scheduled procedure.

The medication is available in a 2 mg/mL vial.

How many mL should the nurse administer? Round off to 2 d.p.

(This is a medical math nd does not require options.)

Choice A rationale

Printing the electronic medical record (EMR) from the backup server may not be the most immediate action required. While having a backup of the EMR is important, it does not address the immediate issue of the system failure.

Choice B rationale

Waiting for notification that the system has been rebooted is a passive approach and may not be the most effective initial action. It does not address the immediate need to communicate the issue to the appropriate department.

Choice C rationale

Identifying information as a late entry in the record is a documentation practice that is used when charting is not completed in a timely manner. However, this action does not address the immediate issue of the system failure.

Choice D rationale

Notifying the information services department of the situation is the correct action. This allows the appropriate department to begin troubleshooting and resolving the issue. In the event of a system failure, the first step should be to report the issue so that it can be addressed as quickly as possible.

Choice A rationale

Exenatide is a medication used to improve blood sugar control in adults with type 2 diabetes. One of the potential side effects of exenatide is pancreatitis, which can cause severe abdominal pain. Therefore, patients should be instructed to notify their healthcare provider if they start having abdominal pain after starting exenatide.

Choice B rationale

Exenatide should be injected within 60 minutes (1 hour) before the morning and evening meal (or before the two main meals of the day, at least 6 hours apart), not 30 minutes before or after a meal. Therefore, this instruction is incorrect.

Choice C rationale

Exenatide does not act in the same way as insulin. While both insulin and exenatide help to control high blood sugar, they work in different ways. Insulin allows sugar in your blood to enter your cells, while exenatide works by increasing the release of insulin when blood sugar levels are high, decreasing the amount of glucose produced and released by the liver, and slowing gastric emptying.

Choice D rationale

There are precautions about taking exenatide with other medications. For example, exenatide may affect the absorption of some orally administered drugs due to its effect on gastric emptying. Therefore, patients should be advised to take oral medications that require rapid absorption at least 1 hour before injecting exenatide.
