A nurse is assisting in the care of a client who is taking chlorpromazine. Which of the following findings indicates a therapeutic effect medication?

A) Increase in concentration: Chlorpromazine is an antipsychotic medication used to manage symptoms of schizophrenia and other psychotic disorders. While it may have some effects on cognition, an increase in concentration is not the primary therapeutic effect of chlorpromazine.

B) Decrease in delusions: Chlorpromazine is effective in reducing symptoms of psychosis, such as delusions and hallucinations, which are common in conditions like schizophrenia. A decrease in delusions is a direct indicator that the medication is having its intended therapeutic effect.

C) Increase in alertness: Chlorpromazine can cause sedation and drowsiness as side effects, particularly during the initial stages of treatment. An increase in alertness would not be a typical therapeutic outcome, and it may even suggest a side effect like overstimulation or anxiety rather than the intended effect.

D) Decrease in anxiety: While chlorpromazine may have some calming effects, it is primarily used to treat symptoms of psychosis, not anxiety disorders. A decrease in anxiety is not the main therapeutic effect of chlorpromazine. Other medications, such as benzodiazepines, are typically used for anxiety management.

A) Rigid abdomen: A rigid abdomen is more commonly associated with conditions like placental abruption or uterine rupture, where there is significant internal bleeding and trauma to the uterine wall. It is not a typical finding in placenta previa, where bleeding is typically present without uterine rigidity.

B) Bright red vaginal bleeding: Bright red vaginal bleeding is the most characteristic finding in placenta previa. The condition occurs when the placenta is abnormally located in the lower part of the uterus, covering or being near the cervix. This leads to painless, bright red vaginal bleeding, which is often seen in the second or third trimester. The bleeding results from the placenta's location as the uterus expands.

C) Persistent uterine contractions: Persistent uterine contractions are more often associated with preterm labor or placental abruption, not placenta previa. While contractions can occur in placenta previa, they are not the primary or most expected symptom. The hallmark of placenta previa is bleeding, rather than contractions.

D) Increased fetal movement: Fetal movement is not typically altered by placenta previa. In some cases, the location of the placenta may affect the feeling of fetal movement, especially if the placenta is anterior, but increased fetal movement is not a specific finding associated with placenta previa. The focus should be on bleeding and uterine stability.
