A client who had a knee replacement surgery receives a prescription for enoxaparin 30 mg subcutaneously every 12 hours for 10 days. The medication is available in 30 mg per 0.3 mL prefilled syringes. How many mL should the practical nurse (PN) administer each day? (Enter numerical value only.)
The Correct Answer is ["0.6"]
- Medication dose: 30 mg enoxaparin
- Medication concentration: 30 mg per 0.3 mL (prefilled syringe)
- Frequency: Every 12 hours
- Duration: 10 days
Calculation:
- Injections per day: Since the medication is given every 12 hours, the client will receive injections 2 times per day (24 hours / 12 hours/injection).
- Total medication per day: To find the total amount of enoxaparin needed per day, multiply the single injection dose by the number of injections:
Total enoxaparin/day = Dose per injection x Number of injections/day = 30 mg/injection x 2 injections/day = 60 mg/day
- Volume of medication per day: Now, we need to find the volume of solution needed to deliver the total daily dose (60 mg) based on the medication concentration (30 mg/0.3 mL). We can achieve this with a proportion:
Volume (mL) / Total dose (mg) = Concentration (mg/mL)
Volume (mL) = (Total dose (mg) x Concentration (mL/mg)) / Concentration (mg/mL)
Plugging in the values:
Volume (mL) = (60 mg x 0.3 mL/mg) / 30 mg/mL
Volume (mL) = 18 mL / 30 mL/mL
Simplifying:
Volume (mL) = 0.6 mL
Therefore, the practical nurse (PN) should administer 0.6 mL of enoxaparin each day.

Correct Answer is A
Explanation
A. Evisceration is the protrusion of internal organs, such as the bowel, through a wound that has reopened. The observation of bowel on the skin indicates this serious complication.

C. Infection could cause wound complications but would not lead to the sudden appearance of bowel outside the body.
D. Dehiscence is the partial or complete separation of wound edges, but it does not involve the protrusion of internal organs. Evisceration is a more severe progression where internal organs are exposed.
