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?

Coenzyme Q10

Probiotics

Valerian

Ginkgo biloba

Answer and Explanation

The Correct Answer is D

A. “Coenzyme Q10”: While coenzyme Q10 is often used for its potential benefits in conditions like heart disease and high blood pressure, it does not typically interact with warfarin.

B. “Probiotics”: Probiotics, which are beneficial bacteria and yeasts, are generally considered safe to use with most medications, including warfarin. They do not typically cause an interaction.

C. “Valerian”: Valerian is often used for its potential benefits in promoting sleep and relaxation. While it can interact with some medications, it is not typically contraindicated for use with warfarin.

D. “Ginkgo biloba”: Ginkgo biloba can increase the risk of bleeding, especially when taken with anticoagulants like warfarin. Therefore, it is contraindicated for concurrent use with warfarin. The nurse should advise the client to stop taking ginkgo biloba and discuss any herbal supplement use with their healthcare provider.

Correct Answer is B

Explanation

A. INR (International Normalized Ratio): INR is primarily used to monitor the effectiveness of anticoagulant therapy, such as warfarin. It is not directly related to the effectiveness of filgrastim, which is a medication used to stimulate the production of white blood cells (WBCs).

B. WBC count: Filgrastim is a granulocyte colony-stimulating factor (G-CSF) that stimulates the bone marrow to produce more white blood cells, particularly neutrophils. Monitoring the WBC count helps assess the effectiveness of filgrastim in increasing the client's white blood cell levels, which is essential for fighting infections.

C. BUN (Blood Urea Nitrogen): BUN is a measure of kidney function and hydration status. While it is an important laboratory value to monitor in many clinical situations, it is not directly related to the effectiveness of filgrastim.

D. Potassium level: Potassium levels are essential for normal cellular function, but they are not specific markers for assessing the effectiveness of filgrastim therapy. Monitoring potassium levels is important for identifying electrolyte imbalances but does not directly evaluate the therapeutic response to filgrastim.

A. Bronchospasms B. Glaucoma C. Diverticulitis D. Diarrhea

Correct Answer is B

Explanation

A) Bronchospasms:
Atropine can be used to treat bronchospasms by dilating the bronchi and bronchioles, thereby increasing airflow to the lungs. It is not contraindicated in clients with bronchospasms.

B) Glaucoma:
Correct. Atropine is contraindicated in clients with glaucoma. Atropine can cause pupillary dilation (mydriasis) and increase intraocular pressure, which can worsen the symptoms of glaucoma and potentially lead to vision loss.

C) Diverticulitis:
Atropine is not contraindicated in clients with diverticulitis. Diverticulitis is inflammation or infection of small pouches (diverticula) that can develop in the walls of the intestines. Atropine can be used to treat various gastrointestinal conditions, including irritable bowel syndrome and diverticulitis, by reducing gastrointestinal motility.

D) Diarrhea:
Atropine can be used to treat diarrhea by slowing gastrointestinal motility and reducing gastrointestinal secretions. It is not contraindicated in clients with diarrhea.
