A nurse is reviewing the medical history of a client who asks about the use of warfarin.
The nurse should identify which of the following findings as a contraindication for the administration of this medication?

Recent myocardial infarction.

Recent eye surgery.

Thrombophlebitis.

Breast cancer.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

Recent myocardial infarction is not a contraindication for warfarin administration. Warfarin is often prescribed for patients with a history of myocardial infarction to prevent clot formation and reduce the risk of stroke.

Choice B rationale:

Recent eye surgery is a contraindication for the administration of warfarin. Warfarin can increase the risk of bleeding, which is particularly concerning after eye surgery due to the delicate nature of ocular tissues. Using anticoagulants in this scenario can lead to severe complications, including vision loss.

Choice C rationale:

Thrombophlebitis, inflammation of a vein with clot formation, is not a contraindication for warfarin administration. In fact, anticoagulants like warfarin are commonly prescribed to prevent the extension of clots and reduce the risk of complications associated with thrombophlebitis.

Choice D rationale:

Breast cancer is not a direct contraindication for warfarin administration. However, the decision to use anticoagulants in patients with a history of breast cancer should be made carefully, considering individual factors such as the stage of cancer, ongoing treatment, and overall risk of thromboembolic events.

Correct Answer is A

Explanation

The correct answer is choice a. Maternal hypoglycemia.

Choice A rationale:

Maternal hypoglycemia can lead to decreased glucose availability for the fetus, which can result in fetal bradycardia due to reduced energy supply.

Choice B rationale:

Fetal anemia typically causes fetal tachycardia rather than bradycardia, as the fetus compensates for the lack of oxygen-carrying capacity by increasing the heart rate.

Choice C rationale:

Chorioamnionitis, an infection of the fetal membranes, usually causes fetal tachycardia due to the inflammatory response and fever.

Choice D rationale:

Maternal fever is more likely to cause fetal tachycardia rather than bradycardia, as the increased maternal temperature can lead to an increased fetal heart rate.

A. An angiocatheter. B. A 25-gauge needle. C. A butterfly needle. D. A noncoring needle.

Correct Answer is D

Explanation

Choice A rationale:

An angiocatheter is not appropriate for accessing an implanted venous access port. Angiocatheters are large-bore catheters designed for rapid fluid administration and are typically used for peripheral venous access. They are not suitable for accessing the small, specialized ports used for central venous access.

Choice B rationale:

A 25-gauge needle is too small for accessing an implanted venous access port. While smaller gauge needles are suitable for delicate procedures and patients with fragile veins, they might not provide adequate flow for certain therapies or blood draws. Accessing a port with a needle that is too small can lead to increased pressure, potentially damaging the port or causing discomfort to the patient.

Choice C rationale:

A butterfly needle is also not the best choice for accessing an implanted venous access port. Butterfly needles, also known as winged infusion sets, are commonly used for short-term peripheral venous access. They are not designed for accessing implanted ports, which require a noncoring needle for precise and safe access without damaging the port membrane.

Choice D rationale:

(Correct Choice) A noncoring needle, also known as a Huber needle, is the correct choice for accessing an implanted venous access port. Noncoring needles have a specially designed tip that creates a smaller puncture hole, reducing damage to the port membrane and minimizing patient discomfort. They are specifically designed for accessing ports and are the standard choice for this procedure.
