The nurse is preparing a prescription for enoxaparin 40 mg subcutaneous (sub) daily. Enoxaparin is available in a pre-filled cartridge labelled, "60 mg per 0.6 mall" How many mL should the nurse administer?
(Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.4"]
Step 1: Determine the concentration of enoxaparin. 60 mg is equivalent to 0.6 mall
Step 2: Set up the ratio to find how many mL corresponds to 40 mg. (40 mg) ÷ (60 mg) = x ÷ (0.6 mL)
Step 3: Solve for x. x = (40 mg) × (0.6 mL) ÷ (60 mg) x = 24 ÷ 60 x = 0.4 mL
So, the nurse should administer 0.4 mL

Correct Answer is B
Explanation
Choice A reason: Drinking several bottles of carbonated water daily is not a well-established risk factor for renal calculi. While hydration is important in preventing kidney stones, carbonation itself does not significantly increase the risk.
Choice B reason: Eating a vegetarian diet with cheese 2 to 3 times a day can increase the risk for kidney stones, especially if the cheese is high in calcium or oxalates. Dairy products, including cheese, contain calcium, and excessive consumption can contribute to the formation of calcium oxalate stones, which are the most common type of kidney stones.
Choice C reason: Experiencing additional stress since adopting a child is not directly related to the formation of kidney stones. Stress can have various health impacts, but it is not a known primary risk factor for renal calculi.
Choice D reason: Jogging more frequently than the usual daily routine is not associated with an increased risk of kidney stones. Regular physical activity is generally beneficial for overall health and does not contribute to the formation of renal calculi.
Correct Answer is C
Explanation
Choice A reason: Effectively managing pain, discomfort, and diarrhea is important for the client’s quality of life, but it does not address the long-term goal of preventing disease progression and complications.
Choice B reason: Ensuring careful fluid and electrolyte balance is critical, especially during acute exacerbations, but it is more of an immediate concern rather than a long-term goal.
Choice C reason: Reducing the number and severity of acute exacerbations is the most important long-term goal for clients with chronic ulcerative colitis. This goal focuses on maintaining remission, preventing complications, and improving overall prognosis by minimizing flare-ups.
Choice D reason: Maintaining a diet that is high in fibber content can be beneficial for overall health but may not always be suitable for clients with ulcerative colitis, especially during flare-ups. It is not the most critical long-term goal for managing the condition.
