A group of student nurses are reviewing the process of drug development. Which statement best identifies the concept of a placebo?

A. Distribution: Distribution refers to the process of a drug moving through the bloodstream to various tissues in the body, not leaving the body.

B. Absorption: Absorption is the process by which a drug enters the bloodstream from the site of administration. It is not related to the drug leaving the body.

C. Metabolism: Metabolism is the process by which the body breaks down a drug, typically in the liver, before it is excreted.

D. Excretion: Excretion is the correct term. It refers to the process by which drugs and their metabolites are eliminated from the body, primarily through the kidneys (urine) or the gastrointestinal tract (feces).

A. "What do the pills look like?" This is a critical question because identifying the medication will guide the nurse in determining the appropriate course of action. However, it should not be the initial response because emergency services should be alerted immediately if the child's life is potentially at risk.

B. “Ask if there is medication to induce vomiting in the household.” Inducing vomiting is not recommended without knowing the specific substance ingested, as it could cause more harm, particularly if the substance is caustic or can lead to aspiration. This is not the best initial action.

C. "Have the child drink a glass of milk." While milk may sometimes be recommended to coat the stomach, this advice is not universally appropriate, particularly without knowing the substance ingested. Milk could interfere with the absorption of some medications or exacerbate the condition.

D. "I'm calling emergency personnel for you now." This is the best response as it ensures immediate medical help is on the way. Time is critical in poisoning cases, and the child may need immediate intervention from professionals.
