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?
Thrombocytopenia
Rheumatoid arthritis
COPD
Thalassemia
The Correct Answer is A
Choice A rationale: Thrombocytopenia (a low platelet count) is a contraindication to heparin therapy because heparin can further increase the risk of bleeding in individuals with reduced platelet levels.
Choice B rationale: Rheumatoid arthritis is not a contraindication to heparin therapy. It is an autoimmune condition affecting the joints.
Choice C rationale: COPD (Chronic Obstructive Pulmonary Disease) is not a contraindication to heparin therapy. Heparin primarily affects the circulatory system.
Choice D rationale: Thalassemia is not a contraindication to heparin therapy.
Thalassemia is a genetic blood disorder affecting hemoglobin production.

Correct Answer is B
Explanation
Choice A rationale: Checking blood pressure in the right arm is contraindicated as it can damage or occlude the graft.
Choice B rationale: Palpating the site for a thrill is a way to assess the patency of an arteriovenous graft. A thrill is a vibration felt over the graft that indicates blood flow.
Choice C rationale: Inserting a saline lock into a site near the graft is contraindicated as it can damage or occlude the graft.
Choice D rationale: Applying pressure to the site is contraindicated as it can damage or occlude the graft.
Correct Answer is D
Explanation
Choice A rationale: Cleansing the site with a hydrogen peroxide solution is not recommended, as it can cause tissue irritation.
Choice B rationale: the correct position of the line is confirmed by a chest x-ray, not by a blood sample.
Choice C rationale: Instructing the client to cough is not necessary and may not be helpful during the insertion of a central venous catheter.
Choice D rationale: This is done to prevent air embolism, which can occur when air enters the bloodstream through the catheter insertion site. Air embolism can cause cardiac arrest, stroke, or respiratory failure.
