In which of the following conditions should decongestants be used with caution?

Choice A rationale
Antidepressants are a class of medications used to treat depression and other mood disorders, not primarily for their sedative and anti-seizure effects.
Choice B rationale
Anxiolytics are medications that inhibit anxiety. They are used to treat anxiety disorders and relieve short-term anxiety symptoms. While some anxiolytics do have sedative effects, they are not derived from barbituric acid.
Choice C rationale

Barbiturates are a class of drugs derived from barbituric acid that act as depressants to the central nervous system. These drugs are used as sedatives or anesthetics and have the potential to become addictive.
Choice D rationale
Benzodiazepines are a class of psychoactive drugs used to treat a range of conditions, including anxiety and insomnia. They are known for their sedative and anxiolytic effects. However, they are not derived from barbituric acid.

Choice A rationale
Administering ordered insulin subcutaneously is the correct method of administration. Insulin is not typically given by other routes.
Choice B rationale
Using an insulin syringe to administer the insulin dose is the correct practice. Insulin syringes are calibrated in insulin units, which helps ensure accurate dosing.
Choice C rationale
Drawing up the ordered dose in a 3 mL syringe is a violation of safe practice. Insulin should always be drawn up in an insulin-specific syringe, which is marked in insulin units, not milliliters.
Choice D rationale
Verifying the drawn-up insulin dose with another nurse is a recommended safety practice in many settings. This double-check can help prevent errors in insulin dosing.
