An adult male who is admitted to the mental health clinic is alert and oriented to person, place, time, and situation. His affect is blunted, his mood dysphoric, and the nurse identifies his responses as tangential with a paranoid theme when he states, “I have a chip inside my head that is speaking to me.” Based on these assessment findings, which nursing problem is best to include in this client’s initial plan of care?

Choice A reason: Protein and albumin reflect nutritional or liver status but are unaffected by enoxaparin, a low-molecular-weight heparin inhibiting factor Xa. These do not monitor anticoagulation effects or complications like bleeding. CBC is critical, as enoxaparin increases bleeding risk, requiring platelet and hemoglobin monitoring to detect serious hematological issues.

Choice B reason: Enoxaparin, an anticoagulant, heightens bleeding risk and can cause thrombocytopenia. Monitoring CBC, especially platelets and hemoglobin, detects heparin-induced thrombocytopenia (HIT) or hemorrhage. This ensures early identification of complications, allowing timely intervention to prevent severe bleeding or thrombosis, making CBC the most critical test for safe administration.

Choice C reason: BUN and creatinine assess renal function, relevant for renally cleared drugs, but enoxaparin is primarily liver-metabolized. Renal monitoring is secondary unless severe impairment exists. CBC is more urgent, as enoxaparin’s anticoagulant effect increases bleeding risk, necessitating hematological surveillance to prevent life-threatening complications.

Choice D reason: Electrolytes like potassium or sodium are not directly affected by enoxaparin’s action on the coagulation cascade. Imbalances may occur in critical illness but are not primary concerns. CBC monitoring for bleeding or thrombocytopenia is critical, as enoxaparin’s anti-Xa activity poses hematological risks requiring immediate attention.

Choice A reason: Elevating the hand reduces edema, potentially improving circulation, but is premature without assessing the absent radial pulse’s cause. Post-fracture, compartment syndrome or arterial injury risks ischemia. Neurovascular assessment identifies severity, guiding targeted interventions to restore perfusion, making elevation secondary to assessment.

Choice B reason: Measuring blood pressure and heart rate provides systemic data but not localized insight into the absent radial pulse, likely from arterial compression post-surgery. Neurovascular assessment evaluates limb perfusion, detecting compartment syndrome or occlusion, critical for urgent intervention to prevent tissue necrosis.

Choice C reason: Completing a neurovascular assessment evaluates pulse, color, warmth, sensation, and movement. Absent radial pulse post-fracture suggests compartment syndrome or arterial injury, risking ischemia. This confirms vascular compromise, guiding interventions like fasciotomy, addressing the pathophysiological threat to limb viability, ensuring timely treatment.

Choice D reason: Notifying the provider follows assessment. Absent radial pulse suggests compartment syndrome, where swelling impairs arterial flow. Neurovascular assessment quantifies severity (e.g., pallor, paresthesia), ensuring accurate reporting for urgent intervention, preventing delays in treating vascular compromise critical to limb preservation.
