A male client has active tuberculosis (TB). Which of the following symptoms will be exhibited?

A. Congenital cataracts are present at birth and are relatively rare. In older adults, cataracts are primarily associated with age-related changes rather than congenital factors.
B. While certain medications used to treat asthma, like corticosteroids, can contribute to the development of cataracts, asthma itself is not a direct cause of cataracts. This connection is not strong enough to be considered a common cause.
C. While eye injuries can lead to cataract formation, they are not the most common cause, especially in the older adult population. Most cataracts develop due to age-related changes rather than trauma.
D. The most prevalent cause of cataracts, especially in older adults, is aging. As people get older, changes in the lens of the eye can lead to clouding, resulting in cataracts. Factors like UV exposure, smoking, and certain medical conditions may also contribute, but aging is the primary and most common factor.

A. Ondansetron is not indicated for treating diarrhea. While nausea can accompany diarrhea, ondansetron specifically targets nausea and vomiting rather than the underlying causes of diarrhea.
B. Ondansetron is primarily used to prevent and treat nausea and vomiting, particularly those associated with chemotherapy, radiation therapy, and postoperative recovery. If a patient is experiencing nausea and vomiting, ondansetron would be the appropriate medication to administer.
C. Ondansetron is not indicated for managing pain. Incisional pain is typically treated with analgesics, not antiemetics. While postoperative patients may experience nausea, ondansetron would not be used solely for pain relief.
D. Paralytic ileus is a condition characterized by the lack of movement in the intestines, leading to a blockage. While nausea and vomiting can occur in this condition, ondansetron is not a treatment for the underlying issue of ileus. The focus would be on managing the ileus and any complications that arise.
