A nurse is caring for a client who is taking warfarin and reports taking several new herbal supplements. The nurse should identify that which of the following supplements is contraindicated for concurrent use with warfarin?

Valerian

Probiotics

Ginkgo biloba

Coenzyme Q10

Answer and Explanation

The Correct Answer is C

A. Valerian is an herbal supplement commonly used for its sedative effects. It does not have a significant interaction with warfarin and is not contraindicated for concurrent use.
B. Probiotics are generally safe to use with warfarin and do not have a significant impact on its anticoagulant effects. They are not contraindicated for concurrent use.
C. Ginkgo biloba is known to increase the risk of bleeding when taken with warfarin. It has antiplatelet effects that can enhance the anticoagulant effects of warfarin, leading to an increased risk of bleeding complications. Therefore, it is contraindicated for concurrent use with warfarin.
D. Coenzyme Q10 is structurally similar to vitamin K and can potentially reduce the effectiveness of warfarin. However, it is not as strongly contraindicated as ginkgo biloba, which has a more pronounced effect on bleeding risk.

Correct Answer is B

Explanation

A. INR (International Normalized Ratio) is used to monitor blood clotting and is not relevant to evaluating the effectiveness of filgrastim. Filgrastim is used to stimulate the production of white blood cells, so monitoring INR would not provide useful information about its effectiveness.
B. WBC count (White Blood Cell count) is the primary laboratory value to monitor when evaluating the effectiveness of filgrastim. Filgrastim is a granulocyte colony-stimulating factor that promotes the production of neutrophils, a type of white blood cell. An increase in WBC count indicates that the treatment is effective.
C. Potassium level is important for overall health but is not directly related to the effectiveness of filgrastim. Monitoring potassium levels is not necessary for assessing the response to filgrastim therapy.
D. BUN (Blood Urea Nitrogen) measures kidney function and is not relevant to evaluating the effectiveness of filgrastim. Monitoring BUN levels would not provide information about the response to filgrastim treatment.

A. Complete an incident report. B. Document the findings in the nurse’s notes. C. Notify the nursing manager. D. Inform the client’s provider.

Correct Answer is D

Explanation

A. Complete an incident report is necessary for documenting the error, but it should not be the first action. Immediate steps should focus on patient safety and addressing the error.
B. Document the findings in the nurse’s notes is important for maintaining accurate medical records, but it should follow the immediate actions taken to address the error.
C. Notify the nursing manager is important for internal reporting and addressing the error within the healthcare team, but it should not be the first action.
D. Inform the client’s provider is the first action the nurse should take. The provider needs to be informed immediately to assess the client’s condition, determine any necessary interventions, and prevent potential harm from the medication error.
