A nurse is teaching a client about preventing osteoporosis. Which of the following statements by the client 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. "I will reduce my intake of sodium." - This statement is correct. High sodium intake can lead to increased calcium excretion through the urine, which can weaken bones. Reducing sodium intake can help prevent osteoporosis.

B. "I will limit my intake of soft drinks." - This statement is correct. Soft drinks, especially cola beverages, contain phosphoric acid, which can leach calcium from bones, leading to decreased bone density. Limiting soft drink consumption is advisable for bone health.

C. "I will decrease my intake of caffeine." - This statement is correct. Excessive caffeine consumption can interfere with calcium absorption and increase calcium excretion. It is advisable to limit caffeine intake to prevent osteoporosis.

D. "I will reduce my intake of vitamin K-rich foods." - This statement is incorrect. Vitamin K is essential for bone health as it helps in bone mineralization and reduces the risk of fractures. Foods rich in vitamin K, such as leafy green vegetables, are beneficial for bone health and should not be reduced unless there are specific medical reasons to do so.
