Four hours following surgical repair of a compound fracture of the right ulna, the nurse is unable to palpate the client’s right radial pulse. Which action should the nurse take first?

Elevate the client’s right hand on one or two pillows.

Measure the client’s blood pressure and apical heart rate.

Complete a neurovascular assessment of the right hand.

Notify the healthcare provider quickly.

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is A

Explanation

Choice A reason: Obtaining another blood pressure measurement is critical, as lethargy, pallor, and diaphoresis suggest hypotension or shock, despite the earlier 140/90 reading. This guides safe administration of antihypertensives, preventing harm, per cardiovascular assessment and medication safety protocols in nursing practice.

Choice B reason: Determining recent medications is important but secondary to assessing current blood pressure, as symptoms suggest acute instability. Blood pressure confirms hypotension risk before reviewing drugs, ensuring timely intervention, per cardiovascular assessment and patient safety standards in nursing care.

Choice C reason: Administering antihypertensives without reassessing blood pressure is unsafe, as lethargy, pallor, and diaphoresis indicate possible hypotension. Confirming blood pressure prevents exacerbating instability, per medication safety and cardiovascular monitoring protocols in nursing practice for clients with hypertension.

Choice D reason: Consulting the PN about the 0800 condition delays immediate assessment of current symptoms. Blood pressure measurement addresses acute lethargy, pallor, and diaphoresis, guiding intervention. Consultation is secondary, per prioritization and cardiovascular assessment standards in nursing care.

A. Dry skin with inelastic turgor. B. Apical rate of 110 beats/minute. C. Serum sodium of 185 mEq/L (185 mmol/L). D. Polyuria and excessive thirst.

Correct Answer is C

Explanation

Choice A reason: Dry skin and inelastic turgor reflect dehydration in DI from antidiuretic hormone deficiency, causing water loss. This is less urgent than hypernatremia (185 mEq/L), which dehydrates brain cells, risking seizures or coma, requiring immediate fluid correction to prevent neurological damage in this critical condition.

Choice B reason: Tachycardia (110 beats/minute) compensates for hypovolemia in DI, where water loss reduces preload, triggering sympathetic activation. This is less critical than hypernatremia (185 mEq/L), which causes cerebral dehydration, necessitating urgent hypotonic fluids to prevent neurological complications, making heart rate secondary.

Choice C reason: Serum sodium of 185 mEq/L indicates severe hypernatremia in DI, where water loss concentrates sodium, dehydrating neurons and risking seizures or coma. Immediate IV hypotonic fluids (e.g., 5% dextrose) correct osmolarity, preventing life-threatening cerebral complications, addressing the urgent pathophysiological crisis in DI.

Choice D reason: Polyuria and thirst are hallmark DI symptoms from water loss but expected and less urgent than hypernatremia (185 mEq/L), which threatens neurological function via osmotic brain injury. Correcting sodium is critical to prevent seizures, making these symptoms secondary to urgent electrolyte management.
