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

A. "Pyelonephritis increases a person's risk for kidney damage." - Pyelonephritis is a bacterial infection of the renal parenchyma and renal pelvis, typically caused by the ascent of bacteria from the lower urinary tract into the kidneys. If left untreated, it can lead to kidney damage, including scarring of the renal tissue and impaired kidney function.

B. "Pyelonephritis is an infection of the lower urinary tract." - This statement is incorrect. Pyelonephritis specifically involves the upper urinary tract, affecting the kidneys. In contrast, infections of the lower urinary tract (such as cystitis) affect the bladder and urethra.

C. "Pyelonephritis often causes no symptoms in affected clients." - This statement is incorrect. Pyelonephritis typically presents with symptoms such as fever, chills, flank pain, painful urination (dysuria), and frequent urination. Clients with pyelonephritis usually experience noticeable symptoms.

D. "Pyelonephritis is most often caused by Staphylococcus saprophyticus." - This statement is incorrect. While Staphylococcus saprophyticus is a common cause of urinary tract infections, pyelonephritis is more commonly caused by gram-negative bacteria, such as Escherichia coli, which often ascend from the lower urinary tract into the kidneys.

A. Sedentary lifestyle - Lack of weight-bearing exercise and physical activity is a significant risk factor for the development of osteoporosis. Weight-bearing exercises help maintain bone density and strength. Sedentary individuals are more prone to osteoporosis.

B. Long-term use of diuretics - Long-term use of certain medications, such as corticosteroids, can increase the risk of osteoporosis. Diuretics are not typically associated with osteoporosis risk, although some medications can affect bone health.

C. Prolonged stress - Chronic stress can have negative effects on overall health, but it is not a direct risk factor for osteoporosis.

D. Obesity - Obesity is generally considered a protective factor against osteoporosis. Individuals with higher body weight tend to have stronger bones due to the mechanical load placed on the bones, reducing the risk of osteoporosis.
