A. A client who is having difficulty breathing with a diagnosis of a fractured femur: Clients experiencing respiratory difficulty require continuous assessment, rapid intervention, and potential critical thinking for changes in status. These responsibilities fall within the RN scope of practice, making this client inappropriate for LVN assignment.

B. A client with a total knee replacement and will be discharged tomorrow: This client is stable, has predictable care needs, and requires routine postoperative tasks such as vitals, dressing checks, and ambulation assistance. These responsibilities are within the LVN’s scope of practice, making this the most appropriate assignment.

C. A new admission with a diagnosis of Congestive Heart Failure: New admissions require comprehensive assessment, identification of acute changes, and nursing judgment for prioritizing care, which are RN responsibilities. LVNs should not manage new admissions independently due to these complex requirements.

D. A transfer client from the ICU with a diagnosis of End-stage Renal Failure: ICU transfers are high-risk and require ongoing assessment, titration of medications, and recognition of rapid deterioration. These responsibilities require RN-level critical thinking and are not appropriate for LVN assignment.

A. Administer a prescribed bronchodilator medication to open the airways: Immediate administration of bronchodilators without assessing the current oxygenation status may overlook the most urgent problem. The client’s drowsiness and bradypnea suggest potential hypoventilation or oxygen-induced hypercapnia, requiring assessment before medication.

B. Assess the client's oxygen saturation level using a pulse oximeter: The first action is to evaluate the client’s oxygenation objectively. Measuring SpO₂ provides critical data to determine the severity of hypoxemia and guides safe interventions. In COPD patients, oxygen adjustments must be carefully titrated to avoid worsening CO₂ retention, making assessment the priority.

C. Increase the oxygen flow rate to 4 L/min to improve oxygenation: Increasing oxygen without assessing saturation may risk suppressing the hypoxic drive in a COPD patient, leading to further CO₂ retention and respiratory depression. Oxygen titration should follow assessment of SpO₂ and clinical status.

D. Reposition the head of the bed to the Semi-Fowler position: Repositioning can enhance lung expansion and ease breathing, but it does not address the immediate need to determine the client’s oxygenation status or the risk of worsening respiratory depression. Assessment takes precedence to guide appropriate interventions.
