Final answer:
The correct advice for menstrual care is to replace tampons every four to six hours to prevent health risks such as toxic shock syndrome. Menstrual cycles can range from 21 to 32 days, and menstrual periods can vary in length from two to seven days.
Step-by-step explanation:
A nurse providing education to adolescents regarding menstrual care should emphasize the importance of changing tampons regularly to prevent risks such as toxic shock syndrome. While tampons can be used by individuals during their menstrual period, it is crucial to replace them every four to six hours to minimize health risks. Toxic shock syndrome is a serious condition that can occur if a tampon is left in for too long, leading to symptoms such as fever, shock, and organ dysfunction.
Additionally, it is important to understand that menstrual cycle length varies from person to person, and even for an individual, it can change from month to month. A cycle can range from 21 to 32 days typically, with the average cycle being about 28 days. The duration of a menstrual period also varies, lasting from two to seven days, with the average being around five days.
Therefore, the correct advice from the given options is that tampons should be replaced every 6 to 8 hours, rather than being used around the clock. This practice helps to ensure menstrual hygiene and reduce the risk of infections and other health complications.
