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 A
Explanation
Choice A reason: Haemoglobin A1C of 6.2% is the best indication of long-term adherence to the prescribed diabetic regimen. The A1C test measures the average blood glucose levels over the past two to three months. A result of 6.2% indicates that the client has been maintaining good blood glucose control over this period, which reflects adherence to the regimen.
Choice B reason: Fasting plasma glucose of 189 mg/dL (10.49 mmol/L) is higher than the normal range. This result indicates poor short-term blood glucose control and suggests that the client may not be adhering to the prescribed regimen effectively.
Choice C reason: Postprandial plasma glucose of 225 mg/dL (12.49 mmol/L) is also higher than the recommended level for post-meal glucose. This result points to poor post-meal glucose control and suggests that the client may not be following their dietary or medication plan properly.
Choice D reason: High-density lipoprotein (HDL) of 40 mg/dL (1.03 mmol/L) is slightly below the recommended level for HDL cholesterol. While HDL is important for cardiovascular health, it is not a direct measure of blood glucose control or adherence to a diabetic regimen.
Correct Answer is C
Explanation
Choice A reason: Carbidopa-levodopa does not primarily reduce the inflammatory process. Its main action is related to dopamine synthesis and availability.
Choice B reason: Carbidopa-levodopa does not slow scarring in the myelin sheath. This medication targets dopamine deficiency, not myelin health.
Choice C reason: Carbidopa-levodopa increases the amount of dopamine in the brain. Dopamine is a neurotransmitter that is crucial for motor control. Parkinson's disease is characterized by dopamine deficiency, and this medication helps to replenish dopamine levels, improving muscle function and reducing symptoms like tremors and stiffness.
Choice D reason: Carbidopa-levodopa is not an antiseizure medication. It is specifically used to manage the motor symptoms of Parkinson's disease by addressing dopamine deficiency.
