A nurse is providing teaching to a client about measures to prevent urinary tract infections (UTIs). Which of the following client statements indicates a need for further teaching?

A. Urinary tract infection
The symptoms described, including recent mental status changes and periods of incontinence, are suggestive of a urinary tract infection (UTI) in an elderly individual. UTIs are common among older adults and can cause a variety of symptoms, including confusion, which is often the primary manifestation in the elderly population. Other symptoms can include urinary urgency, frequency, and incontinence.

B. Acute kidney failure - While acute kidney failure can cause changes in urination and mental status, it is less likely to be the primary cause of these symptoms in this scenario. UTI is a more common and immediate concern given the symptoms described.

C. Septic shock - Septic shock is a severe condition that occurs when an infection leads to a life-threatening drop in blood pressure. While septic shock can cause altered mental status, it is a critical condition that often presents with more dramatic symptoms and requires immediate intensive care management. The symptoms described are more suggestive of a UTI.

D. Urinary stasis - Urinary stasis refers to the slowing or cessation of urine flow. While urinary stasis can contribute to the development of UTIs, it is not a condition that would cause sudden and acute mental status changes and incontinence on its own. UTI is a more likely cause of the symptoms described.

A. Increase sodium intake - This is not a preventive measure for osteoporosis. High sodium intake can lead to increased calcium excretion and weaken bones.

B. Drink a cup of coffee each morning - Caffeine consumption, especially in excess, can interfere with calcium absorption and increase calcium excretion. Limiting caffeine intake is recommended for bone health. Drinking coffee in moderation is acceptable but excessive consumption should be avoided.

C. Have a bone-density scan each year - While bone-density scans (DEXA scans) are useful for diagnosing osteoporosis or assessing bone health, they are not typically recommended for young adults with a family history of osteoporosis unless there are specific risk factors present. Yearly scans are unnecessary and not cost-effective for young adults without significant risk factors.

D. Engage in weight-bearing exercise regularly - Weight-bearing exercises, such as walking, jogging, dancing, and resistance training, help to increase bone density and strength. Regular physical activity, especially weight-bearing exercises, is a recommended preventive measure against osteoporosis.
