Final answer:
b.Sexual activity, being a female, and wearing wet bathing suits are risk factors for cystitis, a type of urinary tract infection. Drinking cranberry juice and breastfeeding are not considered risks for this condition.
Step-by-step explanation:
When considering risk factors for cystitis, which is a type of urinary tract infection (UTI) affecting the bladder, certain behaviors and conditions can increase susceptibility. The correct risk factors from the options provided include: sexual activity, being a female, and wearing wet bathing suits.
Sexual activity can introduce bacteria into the urinary tract, while being female is a risk due to the short urethra's proximity to the anus, increasing the likelihood of fecal bacteria causing an infection. Wet bathing suits can create a moist environment that fosters bacterial growth.
Contrary to the options listed, drinking cranberry juice is often suggested as a preventive measure rather than a risk factor, and breastfeeding has not been established as a risk factor for cystitis. It's important to maintain good hygiene, practice safe sex, and avoid remaining in wet clothing to reduce the risk of UTIs.
