A nurse is reviewing the laboratory data of a client who received 2 units of packed RBCs.

Which of the following laboratory findings should the nurse expect following the transfusion?

The correct answer is choice D. Administer analgesics on a scheduled basis for the first 24 hr.

This is because the child is at risk for developing peritonitis, which can cause severe abdominal pain.

Scheduled analgesics can provide better pain relief than PRN analgesics.

Choice A is wrong because the child should not be given anything by mouth until bowel sounds return, which can take up to 24 hr after surgery.

Giving clear liquids too soon can cause nausea, vomiting, and abdominal distension.

Choice B is wrong because cromolyn nebulized solution is used to prevent asthma attacks, not to treat appendicitis.

There is no indication that the child has asthma or needs this medication.

Choice C is wrong because applying a warm compress to the operative site can increase inflammation and infection risk.

A cold compress can be used to reduce swelling and pain, but only if prescribed by the provider.

The correct answer is B.

Previous violent behavior. According to the web search results, this is the best predictor of future violence among the given risk factors.

Other risk factors include past history of aggression, poor impulse control, and violence. Comorbidity that leads to acts of violence (psychotic delusions, command hallucinations, violent angry reactions with cognitive disorders).

Choice A is wrong because a history of being in prison is not a direct cause of violence, but rather a possible consequence of it.

Choice C is wrong because male gender is not a sufficient factor to predict violence, as there are many other variables involved. Choice D is wrong because experiencing delusions is not necessarily associated with violence, unless they are of a paranoid or persecutory nature.

Normal ranges for violence risk assessment are not standardized, but some tools that can be used include the Historical Clinical Risk Management-20 (HCR-20), the Violence Risk Appraisal Guide (VRAG), and the Psychopathy Checklist-Revised (PCL-R). These tools use different scales and criteria to evaluate the likelihood of violent behavior in individuals.
