Correct Answer is B

Explanation

Choice A rationale

Giving ipecac with a glass of milk is not recommended. Milk can delay the emetic effect of ipecac and potentially interfere with its ability to induce vomiting. It is essential to follow proper guidelines for ipecac administration to ensure its effectiveness and safety.

Choice B rationale

Consulting a poison control center before administering ipecac is crucial. Poison control experts can provide specific recommendations based on the type and amount of substance ingested. Not all poisoning cases require ipecac, and its inappropriate use can cause more harm than good.

Choice C rationale

Ipecac fluid extract is significantly more potent than ipecac syrup and is not recommended for home use. The syrup form is standardized for safe administration in inducing vomiting, whereas the fluid extract can cause severe toxicity if used incorrectly.

Choice D rationale

The emetic effect of ipecac is not immediate. It typically takes about 20 to 30 minutes for vomiting to occur after administration. Providing patients and caregivers with accurate information about the onset of action is essential to avoid unnecessary anxiety.
