A nurse is teaching a client about preventing osteoporosis. Which of the following statements by the client indicates a need for further teaching?

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.

A. McBurney's point on the abdomen: McBurney's point is a location in the right lower quadrant of the abdomen that is significant in the assessment for appendicitis. It is not relevant to the assessment of pyelonephritis, which is a kidney infection.

B. Psoas sign at the knee: The psoas sign is a test for appendicitis, not pyelonephritis. It involves the patient lying on their back and lifting their right leg against resistance. If this movement causes pain in the lower right abdomen, it could indicate irritation of the psoas muscle due to an inflamed appendix.

C. Rovsing's Sign on the abdomen: Rovsing's sign is also a test for appendicitis. It involves palpating the left lower quadrant of the abdomen and observing if it causes pain in the right lower quadrant. The presence of pain in the right lower quadrant during palpation of the left lower quadrant can indicate appendicitis. This sign is not specific to pyelonephritis.

D. Costovertebral angle (CVA) on the back: The CVA is located on the back at the angle formed by the 12th rib and the spine. Percussion of the CVA is a common technique used to assess for kidney tenderness. In the case of acute pyelonephritis, infection and inflammation of the kidneys can cause tenderness and pain in the CVA area. Therefore, this area is assessed for pain related to kidney infections like pyelonephritis.
