Correct Answer is C
Explanation
Choice A Reason:
COPD (Chronic Obstructive Pulmonary Disease) - While COPD might influence the choice of anaesthesia and perioperative management, it is not a direct contraindication to heparin.
Choice B Reason:
Thalassemia - Thalassemia is a genetic blood disorder that affects haemoglobin production and the structure of red blood cells. It does not directly impact the ability to receive heparin.
Choice C Reason:
Thrombocytopenia. Thrombocytopenia, which is a low platelet count, is a contraindication to receiving heparin, an anticoagulant. Heparin works by preventing the formation of blood clots, but if a person has a low platelet count, their ability to form blood clots is already compromised. Administering heparin in this situation could increase the risk of bleeding and further reduce platelet count.
Choice D Reason:
Rheumatoid arthritis - Rheumatoid arthritis is an autoimmune condition affecting joints. It is not a contraindication to heparin use, but the client's overall health and medications should be considered when planning surgery and anticoagulant therapy.
Correct Answer is B
Explanation
Choice A Reason:
Magnesium - While magnesium levels can affect cardiac function, hypomagnesemia is not a primary risk factor for digoxin toxicity.
Choice B Reason:
Potassium. An imbalance of potassium can increase the risk of digoxin toxicity. Hypokalaemia (low potassium levels) enhances the binding of digoxin to its target receptors in the heart, leading to an increased risk of digoxin toxicity. It's essential to monitor potassium levels in clients taking digoxin, as maintaining a stable potassium level helps prevent adverse effects associated with digoxin therapy.
Choice C Reason:
Phosphatase - Phosphate levels are not commonly associated with an increased risk of digoxin toxicity.
Choice D Reason:
Calcium - Calcium levels can affect cardiac function, but they are not a primary factor in the development of digoxin toxicity.
