. A nurse is preparing to administer filgrastim 5 mcg/kg/day subcutaneous to a client who weighs 143 lb. How many mcg should the nurse administer per day? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) _mcg

A) WBC count: Filgrastim is a granulocyte colony-stimulating factor (G-CSF) medication used to stimulate the production of white blood cells (WBCs), particularly neutrophils, in individuals with neutropenia. Therefore, monitoring the WBC count is essential to evaluate the effectiveness of filgrastim therapy. An increase in WBC count indicates a response to treatment, helping to prevent or manage neutropenic complications such as infections.

B) INR: The international normalized ratio (INR) is a laboratory test used to monitor the effectiveness of anticoagulant therapy, particularly warfarin (Coumadin). It measures the clotting ability of the blood and is not directly related to filgrastim therapy. Therefore, monitoring the INR is not appropriate for evaluating the effectiveness of filgrastim treatment.

C) BUN: Blood urea nitrogen (BUN) is a laboratory test used to assess kidney function and hydration status. It measures the concentration of urea nitrogen in the blood and is not directly related to filgrastim therapy. Monitoring BUN levels may be indicated for assessing renal function in certain clinical contexts but is not specific to evaluating the effectiveness of filgrastim treatment.

D) Potassium level: Monitoring potassium levels is important for assessing electrolyte balance and kidney function but is not directly related to filgrastim therapy. Potassium levels may be affected by various factors, including medications, diet, and renal function. However, they do not directly reflect the effectiveness of filgrastim in stimulating WBC production.

A) Ginkgo biloba: This is the correct answer. Ginkgo biloba is contraindicated for concurrent use with warfarin because it can increase the risk of bleeding due to its anticoagulant properties. It can potentiate the effects of warfarin, leading to an increased risk of bruising and bleeding complications.

B) Valerian: While valerian is an herbal supplement used for its sedative effects, it does not typically interact significantly with warfarin. However, caution should still be exercised when combining valerian with any medication due to its potential to cause drowsiness and enhance the effects of other central nervous system depressants.

C) Coenzyme Q10: Coenzyme Q10 is a dietary supplement that is generally well-tolerated and does not have significant interactions with warfarin. It is often used as an antioxidant and for various cardiovascular conditions.

D) Probiotics: Probiotics are beneficial bacteria that can aid in gut health but are unlikely to interact significantly with warfarin. However, it is essential to monitor for any potential changes in gastrointestinal function when starting probiotics concurrently with warfarin.
