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 choice C. Report the findings to the charge nurse. Choice A rationale:

Encouraging the client to drink fluids is not the priority in this situation. While hydration is important, the client's symptoms of muscle soreness, fatigue, and warm skin might indicate a potential adverse reaction to the statin medication, which requires immediate attention.

Choice B rationale:

Monitoring the client's serum lipid levels is not the priority at this moment. The client's current symptoms suggest a possible adverse reaction to the statin medication, and waiting for lipid level results may delay necessary interventions.

Choice C rationale:

Reporting the findings to the charge nurse is the priority action. The client's symptoms could be signs of rhabdomyolysis, a severe and potentially life-threatening condition where muscle breakdown releases toxic substances into the bloodstream. The charge nurse needs to be informed promptly so that appropriate interventions can be initiated.

Choice D rationale:

Administering a PRN dose of acetaminophen is not the priority in this situation. Acetaminophen may help with pain relief, but it will not address the potential underlying issue of muscle soreness and fatigue related to the statin medication.

The correct answer is C. Oriented to person only.

Choice A rationale:

A blood pressure of 144/84 mmHg is slightly elevated but not critically high. While it is important to monitor, it does not immediately impact the instructions for morning care.

Choice B rationale:

An oxygen saturation measurement of 95 to 96% is within the normal range and indicates adequate oxygenation. This is important to monitor but does not require specific changes to morning care instructions.

Choice C rationale:

Being oriented to person only indicates a significant alteration in the client’s cognitive status, which is crucial for the UAP to be aware of. This affects the client’s ability to understand and follow instructions, and may require additional supervision and safety measures during care.

Choice D rationale:

A urinary output of 50 mL/hour is within the normal range (typically 30-50 mL/hour is considered adequate). While it is important to monitor, it does not necessitate immediate changes to morning care instructions.
