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.

Previous violent behavior.

Experiencing delusions.

Male gender.

Answer and Explanation

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.

Correct Answer is D

Explanation

Nail polish remover contains acetone, which is a flammable substance that can ignite in the presence of oxygen. Using nail polish remover around the client can increase the risk of fire and burn injuries.

Choice A is wrong because synthetic fabrics can generate static electricity, which can also cause sparks and ignite oxygen.

The client’s bedding should be made of cotton or wool, which are natural fabrics that do not produce static electricity.

Choice B is wrong because petroleum jelly is a petroleum-based product that can react with oxygen and cause skin irritation or burns.

The client should use water-based moisturizers to soothe the mucous membranes.

Choice C is wrong because alcohol-based cleaning products are also flammable and can cause fires or explosions when exposed to oxygen.

The client should use mild soap and water to clean the equipment, and follow the manufacturer’s instructions for maintenance.

Some general safety tips for home oxygen therapy are:

Keep away from heat and flame, such as candles, matches, lighters, stoves, fireplaces, etc.
Do not smoke or allow others to smoke near the oxygen source
Do not use aerosols, vapor rubs, oils, or other products that contain flammable substances near the oxygen source
Store oxygen tanks or cylinders in a well-ventilated area away from direct sunlight and heat sources
Secure oxygen tanks or cylinders to prevent them from falling or rolling
Use the exact rate of oxygen prescribed by the doctor for each activity
Check the oxygen gauge or level regularly and call the medical supply company when it is low
Use a humidifier bottle if prescribed by the doctor to prevent dryness of the mucous membranes
Change the nasal cannula, mask, and tubing as instructed by the medical supply company to prevent

A. Insert a pillow under the client’s knees. B. Position the client in reverse Trendelenburg. C. Assist the client in the lithotomy position. D. Place a wedge under one of the client’s hips.

Correct Answer is D

Explanation

This is because placing a wedge under one of the hips can help prevent compression of the inferior vena cava by the uterus, which can compromise placental blood flow and cause fetal hypoxia. Placing a wedge under the hip can also help reduce the risk of maternal hypotension, which can also affect fetal oxygenation.
Choice A is wrong because inserting a pillow under the client’s knees can increase the risk of thromboembolism, which is a potential complication of cesarean birth.
Choice B is wrong because positioning the client in reverse Trendelenburg can increase the risk of maternal aspiration, which is another potential complication of cesarean birth.
Choice C is wrong because assisting the client into the lithotomy position can also compress the inferior vena cava and reduce placental blood flow. The lithotomy position is also not necessary for cesarean birth, as the baby is delivered through an incision in the abdomen and uterus.
