An adult client experiences a gasoline tank fire when riding a motorcycle and is admitted to the emergency department (ED. with full thickness burns on both lower extremities. Which percentage of body surface area should the nurse document in the electronic medical record (EMR)?

18%

27%

36%

45%

Answer and Explanation

The Correct Answer is C

Choice A: 18%. This is not the correct percentage, as it only accounts for one lower extremity. According to the rule of nines, each lower extremity accounts for 9% of body surface area on both anterior and posterior sides, so both lower extremities would account for 18% x 2 = 36%.

Choice B: 27%. This is not the correct percentage, as it only accounts for one and a half lower extremities. According to the rule of nines, each lower extremity accounts for 9% of body surface area on both anterior and posterior sides, so one and a half lower extremities would account for 9% x 3 = 27%.

Choice C: 36%. This is the correct percentage, as it accounts for both lower extremities. According to the rule of nines, each lower extremity accounts for 9% of body surface area on both anterior and posterior sides, so both lower extremities would account for 9% x 4 = 36%.

Choice D: 45%. This is not the correct percentage, as it accounts for more than both lower extremities. According to the rule of nines, each lower extremity accounts for 9% of body surface area on both anterior and posterior sides, so more than both lower extremities would account for more than 9% x 4 = 36%.

Correct Answer is ["30"]

Explanation

First, we need to find the concentration of insulin in the IV solution, which is the ratio of insulin units to saline volume. To do this, we use the given information that the IV solution contains 100 units in 250 ml. So, we divide 100 by 250 and get 0.4 units/ml.

Next, we need to calculate the infusion rate in ml/hour for the ordered dose of 12 units/hour. To do this, we use the ratio of insulin units to saline volume, which is 0.4 units/ml. So, we set up a proportion as follows:

0.4/1=12/x

To solve for x, we cross-multiply and get 0.4 x = 12. Then, we divide both sides by 0.4 and get x = 30. So, the infusion rate is 30 ml/hour.

Therefore, the nurse should program the infusion pump to deliver 30 ml/hour..

A. Avoid salt substitutes B. Consume canned vegetables C. Include oatmeal for breakfast D. Identify foods with saturated fats E. Walk 30 minutes per day F. Keep a food diary

Correct Answer is ["A","B"]

Explanation

Choice A: Avoid salt substitutes. This client needs additional education, as salt substitutes may contain potassium, which can increase the risk of hyperkalemia in clients with coronary artery disease. The nurse should teach the client to use herbs, spices, or lemon juice to flavor food instead of salt or salt substitutes.

Choice B: Consume canned vegetables. This client needs additional education, as canned vegetables may contain sodium, which can increase the blood pressure and worsen coronary artery disease. The nurse should teach the client to choose fresh or frozen vegetables instead of canned ones.

Choice C: Include oatmeal for breakfast. This client does not need additional education, as oatmeal is a good source of soluble fiber, which can lower cholesterol and reduce the risk of atherosclerosis. The nurse should praise the client for this healthy choice.

Choice D: Identify foods with saturated fats. This client does not need additional education, as identifying foods with saturated fats is an important step to avoid them. Saturated fats can raise cholesterol and increase the risk of coronary artery disease. The nurse should teach the client to limit saturated fats to less than 10% of total calories per day.

Choice E: Walk 30 minutes per day. This client does not need additional education, as walking 30 minutes per day is a recommended physical activity for clients with coronary artery disease. Physical activity can improve blood circulation, lower blood pressure, and reduce stress. The nurse should encourage the client to walk at a moderate pace and consult with the healthcare provider before starting any exercise program.

Choice F: Keep a food diary. This client does not need additional education, as keeping a food diary is a helpful tool to monitor dietary intake and identify areas for improvement. The nurse should teach the client to record the type, amount, and time of food consumed, as well as any symptoms or feelings associated with eating.
