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 C
Explanation
A. Stating that the healthcare provider left specific instructions may come across as confrontational and does not address the client's emotional state. The focus should be on empathetic communication rather than emphasizing authority.
B. While acknowledging the client’s feelings is important, this response may not de-escalate the situation. It focuses on the necessity of ambulation rather than addressing the client's anger and offering support.
C. Offering to return in 30 minutes provides the client with a sense of control and acknowledges their feelings. It is a supportive and respectful approach that allows time for the client to calm down and prepares them for ambulation.
D. Explaining that ambulation is necessary to avoid complications can sound directive and may not help in managing the client's anger. It is more effective to acknowledge the client's feelings and offer to help at a later time.
Correct Answer is C,A,B,D
Explanation
Rationale
1. Pull the pinna of the ear in an upward and backward direction to straighten the ear canal.
2. Warm the irrigation solution to body temperature to prevent dizziness or discomfort.
3. Ask the client to tilt the head slightly toward the affected side to allow the solution to flow easily into the ear canal.
4. Position an emesis basin close to the neck under the ear to catch the returning solution and cerumen.
5. Direct the flow of the warm solution toward the wall of the ear canal, not directly at the eardrum, to dislodge the impacted cerumen gently
