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 B
Explanation
A) Have suction equipment at the bedside:
Having suction equipment at the bedside is not specifically related to the administration of clopidogrel. It may be necessary for clients with respiratory or airway concerns but is not directly associated with this medication.
B) Monitor the client for black, tarry stools:
Clopidogrel is an antiplatelet medication that can increase the risk of bleeding, including gastrointestinal bleeding. Monitoring for black, tarry stools is essential as it can indicate upper gastrointestinal bleeding, which is a potential adverse effect of clopidogrel therapy.
C) Initiate contact precautions:
Contact precautions are not required for clients taking clopidogrel. Clopidogrel does not pose an infection risk that would necessitate contact precautions.
D) Administer the medication with each meal:
Clopidogrel is typically administered once daily, regardless of meals. There is no specific requirement to administer it with each meal.
Correct Answer is ["94"]
Explanation
To calculate the flow rate for the IV infusion, we can follow these steps:
Identify the total volume to be infused: The total volume of 0.9% sodium chloride (NaCl) solution is 750 mL.
Identify the infusion time: The nurse needs to administer the solution over 8 hours.
Calculate the flow rate: We need to find out how many milliliters (mL) per hour (hr) the IV pump should deliver.
Here's the formula:
Flow rate (mL/hr) = Total volume (mL) / Infusion time (hr)
Flow rate (mL/hr) = 750 mL / 8 hr
Flow rate = 93.75 mL/hr
Rounding the answer: Since we are dealing with medication administration, it's important to round to the nearest whole number to avoid inaccurate dosing. In this case, rounding down is appropriate.
Therefore, the nurse should set the IV pump to deliver 94 mL/hr.
