The nurse is providing teaching to a client who is being discharged with a prescription for warfarin. Which information should be included in the teaching for this medication?

Omit green, leafy vegetables from the diet.

Use over-the-counter pain relief medications.

Obtain laboratory tests as directed.

Use an electric razor for shaving.

Obtain a medical alert bracelet.

Answer and Explanation

The Correct Answer is C

Choice A rationale

While it is true that warfarin’s effectiveness can be affected by vitamin K, found in green leafy vegetables, it is not necessary to completely omit these from the diet. Instead, maintaining a consistent intake of vitamin K can help keep INR levels stable.

Choice B rationale

Over-the-counter pain relief medications, especially those that are nonsteroidal anti- inflammatory drugs (NSAIDs), can increase the risk of bleeding when taken with warfarin. Therefore, this advice is not correct.

Choice C rationale

Regular laboratory tests, specifically the International Normalized Ratio (INR), are crucial when taking warfarin to monitor its effectiveness and adjust the dosage if necessary.

Choice D rationale

Using an electric razor can help prevent cuts and bleeding, which is important because warfarin is a blood thinner. However, this information is not as critical as obtaining regular laboratory tests.

Choice E rationale

Obtaining a medical alert bracelet can be beneficial for individuals taking warfarin, as it can alert healthcare professionals in an emergency situation about the individual’s use of a blood thinner. However, this information is not as critical as obtaining regular laboratory tests.

Correct Answer is A

Explanation

Choice A rationale

The hemoglobin A1C test, also known as the HbA1C or glycated hemoglobin test, is a blood test that evaluates glycemic control over a 3-month period by measuring the glucose attached to hemoglobin. This test is commonly used to diagnose and monitor diabetes. It provides an average of your blood sugar levels over the past 2-3 months, which can help healthcare providers assess how well diabetes is being managed.

Choice B rationale

The hemoglobin A1C test does not use the level of serum protein to evaluate glycemic control. Instead, it measures the amount of glucose that is attached to the hemoglobin in your red blood cells.

Choice C rationale

The hemoglobin A1C test does not evaluate serum ketone production over several days. Ketones are produced when the body burns fat for energy, which can occur when there is not enough insulin to help your body use sugar for energy. High levels of ketones can lead to diabetic ketoacidosis, a serious condition that requires immediate medical attention.

Choice D rationale

The hemoglobin A1C test does not determine the amount of glucose attached to hemoglobin over the last seven days. Instead, it provides an average of your blood sugar levels over the past 2-3 months. -

A. Administer the prescribed antibiotic early. B. Apply a sterile dressing to the area. C. Report the finding to the care provider. D. Obtain a culture of the incision.

Correct Answer is C

Explanation

Choice A rationale

Administering the prescribed antibiotic early might not be the most immediate action. While antibiotics can help treat an infection, it’s crucial to first confirm the presence of an infection before starting antibiotic therapy.

Choice B rationale

Applying a sterile dressing to the area is important, but it’s not the priority nursing action. Dressings help protect the wound from further contamination, but they do not address the underlying issue of a potential infection.

Choice C rationale

Reporting the finding to the care provider is the priority nursing action. The symptoms described - a new foul odor coming from the incision, which is erythematous, tender, and warm to the touch - suggest a possible infection. Immediate reporting allows for prompt evaluation and treatment, which is crucial in preventing further complications.

Choice D rationale

Obtaining a culture of the incision might be necessary to identify the specific causative agent of the infection, but it’s not the priority action. It’s more important to first report the findings to the care provider.
