A nurse is teaching a client how to manage edema following knee replacement surgery. Which of the following interventions should the nurse include in the teaching?
Apply ice packs for 15 minutes every hour.
Elevate the affected leg above the heart level.
Consume nutrition-dense foods first.
Wear compression stockings during the day.
The Correct Answer is B
Choice A reason: Applying ice packs for 15 minutes every hour is not an effective intervention for managing edema following knee replacement surgery because it can impair blood circulation and delay healing. Ice packs can also cause frostbite or nerve damage if applied for too long or too frequently. Ice packs should be used only for the first 24 to 48 hours after surgery and with a cloth barrier between the skin and the ice.
Choice B reason: Elevating the affected leg above the heart level is an effective intervention for managing edema following knee replacement surgery because it can reduce swelling and pain by facilitating venous return and lymphatic drainage. Elevation can also prevent blood clots and infection by improving blood flow and oxygen delivery to the wound site.
Choice C reason: Consuming nutrition-dense foods first is not a relevant intervention for managing edema following knee replacement surgery because it does not directly affect fluid balance or wound healing. Nutrition-dense foods are those that provide high amounts of nutrients per serving, such as eggs, cheese, nuts, beans, and meat. Nutrition-dense foods are important for overall health, but not specifically for edema management.
Choice D reason: Wearing compression stockings during the day is not a recommended intervention for managing edema following knee replacement surgery because it can interfere with wound healing and increase the risk of infection. Compression stockings can also cause skin irritation, blisters, or ulcers if worn incorrectly or too tightly. Compression stockings should be avoided until the wound is fully healed and only used under medical supervision.

Correct Answer is B
Explanation
Choice A reason: Hamburger is not a suitable food item for a lacto-vegetarian diet because it is made from ground beef, which is an animal product. A lacto-vegetarian diet excludes meat, poultry, fish, and eggs, but allows dairy products.
Choice B reason: Cheese is a suitable food item for a lacto-vegetarian diet because it is a dairy product, which is allowed in this type of diet. Cheese provides protein, calcium, and vitamin B12 for lacto-vegetarians.
Choice C reason: Eggs are not a suitable food item for a lacto-vegetarian diet because they are an animal product. Eggs are excluded from a lacto-vegetarian diet, but they are allowed in an ovo-lacto vegetarian diet, which also includes dairy products.
Choice D reason: Shrimp is not a suitable food item for a lacto-vegetarian diet because it is a seafood product, which is an animal product. Seafood is excluded from a lacto-vegetarian diet, but it is allowed in a pescatarian diet, which also includes dairy products and eggs.
Correct Answer is A
Explanation
Choice A reason: Serum creatinine 3.5 mg/dL is high and indicates the need for further assessment. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys. High creatinine levels can indicate kidney damage or impaired renal function.
Choice B reason: Hematocrit 45% is within the normal range (37-47% for women, 40-50% for men), and it does not indicate the need for further assessment. Hematocrit is the percentage of red blood cells in the blood. Low hematocrit levels can indicate anemia, bleeding, or hemolysis.
Choice C reason: Blood urea nitrogen 18 mg/dL is within the normal range (7-20), and it does not indicate the need for further assessment. Blood urea nitrogen is a waste product of protein metabolism that is filtered by the kidneys. High blood urea nitrogen levels can indicate dehydration, kidney damage, or high protein intake.
Choice D reason: Sodium 140 mEq/L is within the normal range (135-145), and it does not indicate the need for further assessment. Sodium is an electrolyte that helps maintain fluid balance, blood pressure, and nerve impulses. Low or high sodium levels can cause confusion, seizures, or coma.
