A nurse is collecting data from a client about risk factors for cardiovascular disease. The nurse should identify that which of the following findings is a modifiable risk factor?

A. Reduced fat in the stools is correct. Pancrelipase is an enzyme replacement therapy that helps improve digestion and absorption of fats and proteins in individuals with cystic fibrosis. This treatment is especially important for those with pancreatic insufficiency, as it helps prevent the steatorrhea (fatty stools) commonly seen in these patients.

B. Decreased sodium excretion is incorrect. Pancrelipase does not directly affect sodium balance in the body. Cystic fibrosis patients may experience increased sodium excretion, which requires special management of fluid and electrolytes.

C. Improved respiratory function is incorrect. While pancrelipase improves digestion, it does not directly affect respiratory function, which is primarily impacted by the progressive lung disease in cystic fibrosis.

D. Improved absorption of vitamins B and C is incorrect. While pancrelipase helps with fat absorption, it primarily improves the absorption of fat-soluble vitamins (A, D, E, K) rather than water-soluble vitamins like B and C.

A. The client should use a hair dryer on a warm setting to relieve itching inside the cast is incorrect. Using a hair dryer could cause skin burns or damage the cast. Additionally, the client should avoid introducing moisture into the cast, which could lead to skin irritation or infection.

B. The client's extremity should be elevated after the cast is applied is correct. Elevating the extremity helps reduce swelling and inflammation during the initial phase after cast application. It is important to elevate the limb above the level of the heart to promote venous return and reduce swelling.

C. The client can shower with the cast after 24 hr is incorrect. The plaster cast should not get wet. The nurse should instruct the client to keep the cast dry at all times. A plastic cover or cast protector should be used when showering to prevent moisture from seeping into the cast.

D. The client should keep the cast covered until it is dry is incorrect. It is true that the cast should be kept dry, but keeping it covered is not enough. The primary concern is preventing moisture and ensuring the plaster cast is allowed to air dry in a well-ventilated area without getting wet.
