A nurse is assisting in the education of a group of clients about the contraindications of warfarin therapy. Which of the following statements is appropriate to include in the instructions?
"Clients who have rheumatoid arthritis should not take warfarin."
"Clients who have diabetes mellitus type 1 should not take warfarin"
"Clients who have hypertension should not take warfarin"
"Clients who are pregnant should not take warfarin"
The Correct Answer is D
A) "Clients who have rheumatoid arthritis should not take warfarin":
Rheumatoid arthritis itself is not a contraindication for warfarin therapy. However, close monitoring is required due to potential interactions with medications used to treat rheumatoid arthritis and the increased risk of bleeding associated with both conditions.
B) "Clients who have diabetes mellitus type 1 should not take warfarin":
Type 1 diabetes mellitus is not a contraindication for warfarin therapy. However, diabetes increases the risk of complications such as peripheral vascular disease, which may necessitate careful monitoring of INR levels and adjustments to warfarin dosage.
C) "Clients who have hypertension should not take warfarin":
Hypertension alone is not a contraindication for warfarin therapy. However, hypertension is a risk factor for cardiovascular diseases that may require anticoagulation therapy. Close monitoring of blood pressure and potential interactions with antihypertensive medications is essential.
D) "Clients who are pregnant should not take warfarin":
Pregnancy is a contraindication for warfarin therapy due to its teratogenic effects, which can cause fetal harm or birth defects. Pregnant clients requiring anticoagulation therapy may be prescribed alternative medications that are safer during pregnancy, under the guidance of a healthcare provider.

Correct Answer is D
Explanation
A) To provide analgesia:
Aspirin is primarily used as an antiplatelet medication in the context of myocardial infarction (MI) and coronary artery disease (CAD). While aspirin can provide mild pain relief (analgesia), its main therapeutic effect in this scenario is not for pain management.
B) To reduce inflammation:
Aspirin does have anti-inflammatory properties, but its use in preventing cardiovascular events like myocardial infarction is primarily due to its antiplatelet effects rather than its anti-inflammatory properties.
C) To prevent fever:
Aspirin is sometimes used to reduce fever, but its role in preventing cardiovascular complications like clot formation after myocardial infarction is more crucial and unrelated to fever prevention.
D) To prevent blood clotting:
Aspirin inhibits platelet aggregation and reduces the risk of blood clot formation. This antiplatelet effect is beneficial in preventing further clot formation in coronary arteries, which is critical in the management of myocardial infarction and coronary artery disease.
Correct Answer is D
Explanation
A) Pantoprazole:
Pantoprazole is a proton pump inhibitor used to reduce stomach acid. It does not typically require withholding before radiological studies with IV contrast dye.
B) Simvastatin:
Simvastatin, a statin medication used to lower cholesterol, does not need to be withheld before radiological studies with IV contrast dye.
C) Valsartan:
Valsartan, an angiotensin II receptor blocker used for hypertension, does not typically need to be withheld before radiological studies with IV contrast dye.
D) Metformin:
Metformin, an oral antidiabetic medication, should be withheld before radiological studies with IV contrast dye. There is a risk of lactic acidosis when metformin interacts with IV contrast dye, particularly in clients with impaired renal function.
