A nurse is reviewing laboratory findings for a client who is to receive a dose of enoxaparin. For which of the following laboratory values should the nurse withhold the dose and notify the provider?

A. Potassium level: Potassium measurement is used to assess electrolyte balance and kidney function, but it does not provide information about platelet function or clotting ability. It is not relevant for evaluating petechiae or ecchymoses.

B. Prealbumin: Prealbumin is a marker of nutritional status and protein intake. While important for overall health, it does not help identify the cause of bleeding disorders or thrombocytopenia.

C. Creatinine clearance: Creatinine clearance assesses renal function and is unrelated to platelet levels or coagulation abnormalities. It would not provide diagnostic information for clients presenting with bleeding manifestations.

D. Platelet count: A platelet count is essential for evaluating clients with generalized petechiae and ecchymoses because these signs suggest thrombocytopenia or platelet dysfunction. Measuring platelet levels helps determine the severity of the disorder and guides further diagnostic and therapeutic interventions.

A. Interpret the client's need for pain medication: Determining the need for analgesia requires professional nursing judgment and assessment, which is outside the AP’s scope of practice. The nurse must evaluate pain and make medication decisions.

B. Change a sterile dressing on a client's open incisional wound: Sterile dressing changes involve invasive procedures and assessment of wound healing, which are nursing responsibilities. APs can assist with non-sterile care but cannot perform sterile interventions independently.

C. Educate a client on the use of a glucometer: Patient education involves teaching, assessing understanding, and clinical judgment, all of which require nursing expertise. APs can reinforce teaching but cannot independently instruct clients on medical device use.

D. Perform cardiopulmonary resuscitation on a client: CPR is a basic life-saving procedure that APs are trained and authorized to perform in emergencies. This task falls within the AP’s scope of practice and can be done under general supervision until advanced help arrives.
