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 B
Explanation
A. Suggesting a less strenuous activity is not necessary as physical activity is beneficial in managing pre-diabetes.
B. Reassuring the parents that increased physical activity reduces the risk for diabetes encourages healthy habits and supports the child’s desire to participate in sports.

Correct Answer is A
Explanation
A. Hoarseness in the voice following a thyroidectomy can be a sign of vocal cord damage or laryngeal nerve injury, which are potentially serious complications. The appropriate action is to notify the unit charge nurse to escalate the finding for further assessment by a physician or advanced practice provider.
B. Administering humidified oxygen does not specifically address the issue of hoarseness. While humidified oxygen might be beneficial for general respiratory comfort, it is not a targeted intervention for potential vocal cord damage.
C. Ensuring that the drainage device is compressed is important for managing surgical wounds but does not address or diagnose vocal cord issues. Hoarseness after thyroid surgery is more indicative of a potential complication rather than a drainage issue.
D. Obtaining ice chips does not address the underlying cause of the hoarseness and may not provide significant relief. The priority is to identify potential complications rather than offering symptomatic relief.
