A charge nurse is teaching new staff members about factors that increase a client's risk to become violent. Which of the following risk factors should the nurse include as the best predictor of future violence?
A history of being in prison
Male gender
Previous violent behavior
Experiencing delusions
The Correct Answer is C
A. While this may be a risk factor for some behaviors, it is not as strong a predictor of violence as a history of actual violent behavior.
B. Although statistics show higher rates of violence among males, it's not a specific predictor for individual behavior.
C. Previous violent behavior is the strongest predictor of future violence.
Understanding a client's history of violence is critical in assessing risk and planning interventions.
D. While certain types of delusions may increase risk, they are not as definitive in predicting violence as past violent behaviors.

Explanation
Yellowing of the eyes could indicate hepatotoxicity, a serious adverse effect associated with some of the anti-tuberculosis medications, particularly rifampin.
Blurred vision could be a sign of optic neuritis, a rare but serious adverse effect associated with ethambutol.
Abdominal pain could indicate hepatitis or hepatotoxicity, which are potential adverse effects of anti-tuberculosis medications like isoniazid and rifampin.
Increased bruising could indicate thrombocytopenia, a serious adverse effect associated with some anti-tuberculosis medications, particularly rifampin.
Increased bleeding tendency could also indicate thrombocytopenia or other hematologic abnormalities.
Red/orange tint to urine could indicate rifampin-induced discoloration of bodily fluids, which is not harmful but can be alarming to patients.
Darkening of urine could also be a result of rifampin-induced discoloration. It's important to differentiate between this harmless side effect and hematuria, which could indicate a more serious issue.
Correct Answer is A
Explanation
To calculate the IV infusion rate for dopamine hydrochloride, we first need to convert the dose from micrograms per kilogram per minute (mcg/kg/min) to milligrams per hour (mg/hr). The patient weighs 80 kg and the prescribed dose is 4 mcg/kg/min.
First, calculate the dose in mcg/hr: 4 mcg/kg/min x 80 kg x 60 min/hr = 19200 mcg/hr.
Next, convert mcg to mg: 19200 mcg/hr / 1000 mcg/mg = 19.2 mg/hr.
We have an 800 mg dopamine hydrochloride solution in a 250 mL bag. To find out how many mL/hr to administer, we use the following proportion:
(800 mg / 250 mL) = (19.2 mg / X mL).
Solving for X gives us X = (19.2 mg * 250 mL) / 800 mg, which equals 6 mL/hr.
Therefore, the nurse should set the IV infusion pump to deliver 6 mL/hr.
