The nurse is caring for a client who is diagnosed with an arterial insufficiency ulcer. The nurse should plan interventions to address which priority issue?

A. "I will reduce my intake of vitamin K-rich foods."
Vitamin K is essential for bone health as it helps in the regulation of calcium within bones and blood vessels. Therefore, reducing the intake of vitamin K-rich foods would not be beneficial for preventing osteoporosis. In fact, adequate intake of vitamin K is important for bone health.

B. "I will limit my intake of soft drinks." - Soft drinks, especially cola beverages, contain phosphoric acid, which can leach calcium from bones, making them weaker and more susceptible to fractures.

C. "I will reduce my intake of sodium." - High sodium intake can lead to increased calcium excretion in the urine, potentially weakening bones over time. Reducing sodium intake can help in preventing bone loss.

D. "I will decrease my intake of caffeine." - Excessive caffeine consumption can interfere with calcium absorption, contributing to bone loss. Decreasing caffeine intake is advisable for maintaining bone health.

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.
