A nurse is assessing a client who has risk factors for developing heart disease. Which of the following factors does the nurse recognize as a modifiable risk factor?

A. A feeling of swelling in the feet: Swelling in the feet can be caused by various factors such as fluid retention, circulatory issues, or certain medical conditions like venous insufficiency. It is not a typical symptom of anaphylaxis, which usually involves more generalized symptoms such as hives, itching, swelling of the face or throat, difficulty breathing, and a drop in blood pressure.

B. Pain at the injection site: Pain at the injection site is a common side effect of receiving an injection or medication. It occurs due to tissue irritation or trauma from the needle. While allergic reactions can cause localized redness, swelling, or itching at the injection site, severe pain alone is not a hallmark symptom of anaphylaxis.

C. A sudden decrease in heart rate: Anaphylaxis typically leads to an increase in heart rate (tachycardia) rather than a decrease. This increase in heart rate is a response to the body's attempt to compensate for the drop in blood pressure caused by anaphylaxis. Bradycardia (a decrease in heart rate) is not a typical feature of anaphylaxis unless it occurs very late in a severe reaction due to profound circulatory collapse.

D. A sharp decrease in blood pressure: This choice is indicative of an understanding of possible anaphylaxis. Anaphylaxis can cause a rapid and severe drop in blood pressure, known as hypotension. This drop in blood pressure is often a key feature of anaphylaxis and can lead to symptoms such as dizziness, fainting, confusion, and shock.

A. "I will walk three times per week."

Regular weight-bearing exercises, such as walking, are beneficial for maintaining bone density and reducing the risk of osteoporosis in older adults. Weight-bearing activities help stimulate bone formation and strengthen bones. Therefore, the client's statement about walking three times per week demonstrates an understanding of an effective measure for reducing the risk of osteoporosis.

B. "I will avoid exposure to the sun." - Exposure to sunlight is essential for vitamin D synthesis, which helps the body absorb calcium and maintain bone health. Therefore, avoiding sunlight would not be beneficial for reducing the risk of osteoporosis.

C. "I will decrease my intake of dairy products." - Dairy products are a rich source of calcium, which is crucial for bone health. Decreasing intake of dairy products may lead to inadequate calcium intake, increasing the risk of osteoporosis.

D. "I will take 250 milligrams of calcium once per day." - While calcium supplementation is important for maintaining bone health, the recommended daily intake for older adults is higher than 250 milligrams. The client's statement suggests an inadequate understanding of calcium supplementation for osteoporosis prevention.
