The LPN/LVN is aware of the drug cycle that begins with the administration of a drug. Which factor(s) would influence the amount of time needed to complete the drug cycle of a drug?  Select all that apply.  

A. Complete blood count (CBC): A CBC is a standard laboratory test to evaluate overall health and detect a wide range of disorders, including infection or anemia. It is not contraindicated and may be necessary for comprehensive patient care.

B. Placement on a cardiac monitor: Cardiac monitoring is appropriate in cases of overdose as many substances can affect the heart. It helps in early detection of any arrhythmias or other cardiac complications.

C. Activated charcoal: Activated charcoal is typically used to bind substances in the gastrointestinal tract to prevent absorption. However, in the case of a caustic substance, it is generally contraindicated because it does not bind well to such substances and may obscure endoscopic evaluation.

D. Inducing vomiting: Inducing vomiting is contraindicated in cases of caustic substance ingestion because it can cause additional damage to the esophagus and mouth. It is important to avoid this action to prevent further injury.

A. Call the health-care provider to see if intravenous fluids are needed: This is not usually necessary unless the patient has a condition that requires it. It's more important to ensure NPO status is maintained.

B. Increase fluid intake prior to midnight to make sure the patient remains hydrated: This could be done, but it is less important than ensuring the patient follows the NPO instructions.

C. Remove the patient's water pitcher at the bedside shortly before midnight: This is the correct answer. Removing the pitcher helps prevent the patient from accidentally drinking water and violating NPO status.

D. This is an example of a STAT order and should be documented in the patient's chart: NPO orders are not STAT orders; they are routine orders related to the preparation for a procedure.
