A nurse is reviewing the medical record of a client who is to undergo open heart surgery. Which of the following findings should the nurse report to the provider as a contraindication to receiving heparin?

A. Place pillows under the client's knees: Placing pillows under the knees can lead to venous stasis, increasing the risk of deep vein thrombosis (DVT). Prolonged knee flexion can also reduce circulation and contribute to joint stiffness. Instead, the client should be encouraged to keep their legs extended and change positions frequently to promote blood flow.

B. Avoid use of anticoagulants: Anticoagulants are commonly prescribed after surgery to prevent thromboembolic complications such as DVT and pulmonary embolism. Avoiding them may increase the client's risk of clot formation, especially if they have limited mobility. The decision to withhold anticoagulation should be based on specific contraindications rather than routine avoidance.

C. Discourage leg exercises while in bed: Leg exercises help prevent blood pooling in the lower extremities, reducing the risk of DVT. Discouraging movement can lead to complications such as impaired circulation, muscle stiffness, and clot formation. Encouraging active and passive range-of-motion exercises supports recovery and decreases the likelihood of postoperative complications.

D. Apply compression stockings to the lower extremities: Compression stockings help improve venous return and reduce the risk of clot formation by preventing blood from pooling in the lower extremities. They are particularly beneficial for clients with limited mobility after surgery. Using them in combination with early ambulation and anticoagulation therapy further decreases the risk of thromboembolic events.

The first action the nurse should take is assess for dizziness when standing followed by increase dietary iron intake.

Rationale:

Assess for dizziness when standing: The client’s orthostatic hypotension (BP drops from 132/60 to 102/50 mmHg upon standing) and tachycardia (HR 108/min) suggest possible symptomatic anemia. Evaluating for dizziness ensures client safety and helps determine the severity of anemia-related hypoxia.

Increase dietary iron intake: The client has iron deficiency anemia (low hemoglobin, hematocrit, RBC count, and ferritin). Since they follow a vegan diet, increasing plant-based iron sources (e.g., leafy greens, legumes, fortified cereals) and vitamin C intake can improve iron absorption.

Incorrect:

Administer IV fluids: While anemia can cause orthostatic hypotension, fluid resuscitation is not the first-line intervention unless dehydration is present.

Check for signs of bleeding: The client reports no pain or discomfort, and there is no evidence of active bleeding. Anemia is more likely due to chronic dietary deficiency rather than acute blood loss.

Administer vitamin B12 supplements: The client’s vitamin B12 level is slightly low but not critically deficient. The primary issue is iron deficiency, not pernicious anemia.
