A client who had 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"]
Step 1: The medication is prescribed as 30 mg every 12 hours, which means it is given twice a day. So, the total daily dosage in mg is 30 mg × 2 = 60 mg.
Step 2: The medication is available in 30 mg per 0.3 mL. So, to find out how many mL correspond to 60 mg, we set up a proportion: (30 mg / 0.3 mL) = (60 mg / x mL). Solving for x gives x = (0.3 mL / 30 mg) × 60 mg = 0.6 mL.
Therefore, the practical nurse should administer 0.6 mL of the medication each day.

Correct Answer is B
Explanation
This is the best intervention for the PN to implement because it relieves the muscle spasm and reduces the pain of a leg cramp. Leg cramps are common during pregnancy and labor due to changes in calcium levels, fluid balance, or pressure on nerves and blood vessels.
A. Massaging the calf and foot is not recommended because it may increase pain or cause injury to the muscle or nerve.
C. Checking the pedal pulse in the affected leg is not necessary unless there is a suspicion of vascular compromise or thrombosis, which are unlikely causes of a leg cramp.
D. Elevating the leg above the heart is not helpful because it may impair blood flow or increase pressure on the nerve or muscle.
Correct Answer is A
Explanation
Choice A rationale:
After administering hydrocodone/acetaminophen for pain, the PN should closely monitor the client for signs of respiratory depression, which may manifest as shallow or slow breathing.
Ongoing assessments are crucial because respiratory depression is a potential adverse effect of opioid medications like hydrocodone. If this complication is detected early, appropriate interventions can be implemented to ensure the client's safety.
Choice B rationale:
Assessing the skin daily for areas of ecchymosis or other signs of bleeding is not directly related to the administration of hydrocodone/acetaminophen. While bruising and bleeding are possible side effects of some medications, this assessment is not the priority in this scenario.
Choice C rationale:
Encouraging the client to resume normal activities after medication administration is not appropriate in this situation. Hydrocodone/acetaminophen can cause drowsiness and impairment, so the client should be advised to avoid activities that require alertness or coordination until the effects of the medication are known.
Choice D rationale:
Observing the client for involuntary movements of the lips and tongue is relevant when administering antipsychotic medications, as these movements may be signs of tardive dyskinesia. However, it is not directly related to the use of hydrocodone/acetaminophen. The priority after administering this pain medication is to monitor for respiratory depression, as opioids can affect the respiratory system
