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.)

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

Choice A reason: Reviewing the client's fluid intake prior to bedtime is important for managing nocturia, but it does not address the immediate concern of urinary retention and difficulty starting the urinary stream.

Choice B reason: Obtaining a fingerstick blood glucose level is relevant for diagnosing diabetes, which can cause increased urination. However, it does not directly address the current urinary symptoms.

Choice C reason: Collecting a urine specimen for culture analysis can help identify a urinary tract infection, but it does not provide immediate assessment information regarding the client's bladder status.

Choice D reason: Palpating the bladder above the symphysis pubis is the most immediate and relevant intervention. This assessment helps determine if the bladder is distended, indicating urinary retention, which is a common issue in older adult males and can cause the symptoms described.
