A nurse is caring for a school-age child who is taking valproic acid. The nurse should expect the provider to order which of the following diagnostic tests?

- A. Hypotension is not an adverse effect of epinephrine, but rather a sign of anaphylaxis that epinephrine can help to reverse by causing vasoconstriction and increasing blood pressure.

- B. Report of tinnitus is not an adverse effect of epinephrine, but rather a symptom of aspirin toxicity, which can occur in some clients who take aspirin for allergic reactions.

- C. Report of chest pain is an adverse effect of epinephrine, as it can cause cardiac dysrhythmias, angina, and myocardial ischemia by increasing the heart rate and oxygen demand of the myocardium.

-D. Ecchymosis is not an adverse effect of epinephrine, but rather a sign of bleeding disorders or trauma that can cause bruising under the skin.

- A is correct because delegating non-nursing tasks to ancillary staff allows nurses to focus on more complex and skilled tasks that require their expertise and judgment, thus improving efficiency and quality of care.

- B is incorrect because stocking client rooms with extra supplies increases waste and costs, as well as clutter and infection risk.

- C is incorrect because assigning dedicated equipment to each client's room reduces availability and accessibility of equipment for other clients, as well as increases maintenance and cleaning costs.

- D is incorrect because changing continuous IV infusion tubing every 24 hr is not cost-effective, as it does not reduce the risk of infection significantly compared to changing it every 72 hr, according to current evidence-based practice guidelines.
