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. Modern ICDs are designed to withstand interference from household appliances like microwaves.
B. Wearing loose clothing over the implant site can help avoid irritation and discomfort around the ICD.
C. It is recommended to keep cell phones at least six inches away from the ICD to avoid potential electromagnetic interference.
D. There is no general restriction against showering with an ICD; precautions mainly focus on the period immediately after implantation.

A. Contact precautions are not indicated based on the assessment findings provided. Preeclampsia is primarily a hypertensive disorder of pregnancy characterized by systemic manifestations such as elevated blood pressure, proteinuria, and multiorgan involvement. It is not transmitted through direct contact, so contact precautions are unnecessary.

B. The client is exhibiting signs and symptoms consistent with preeclampsia, including right upper abdominal pain, headache, nausea, vomiting, facial edema, weight gain, and elevated blood pressure. Monitoring urinary output is essential for assessing renal function and detecting oliguria, which is a potential complication of preeclampsia.

C. Reducing stimuli, such as bright lights and loud noises, can lower the risk of seizures in clients with preeclampsia.

D. The client's blood pressure readings are elevated, indicating hypertension, which is a hallmark sign of preeclampsia. Monitoring blood pressure regularly is crucial for assessing the severity of hypertension and guiding management.

E. Amniocentesis is not indicated based on the assessment findings provided. Amniocentesis is a diagnostic procedure typically performed to obtain amniotic fluid for various purposes, such as fetal lung maturity assessment or genetic testing. In the context of preeclampsia, it is not a standard intervention.

F. Internal fetal monitoring is typically used during labor to provide a more accurate reading of the baby's heart rate. It involves guiding a thin wire through the cervix and attaching it to the baby's scalp. At 30 weeks gestation, internal monitoring would not be standard practice as it is invasive and labor has not yet commenced.

G. Deep tendon reflexes (DTRs) are assessed to monitor for signs of neurological involvement in preeclampsia. Hyperreflexia, as indicated by a 3+ DTR bilaterally, is a characteristic finding in severe preeclampsia and may indicate central nervous system irritability.

H. Bed rest is often recommended for clients with preeclampsia to reduce physical activity and minimize the risk of complications such as eclampsia or stroke. It can help lower blood pressure and reduce the risk of placental abruption.
