The patient is to be started on warfarin (Coumadin) therapy. It is important for the nurse to check for the use of which herbs? (Select All that Apply)
Valerian
Ginkgo biloba
Echinacea
Ginger
Garlic
Correct Answer : B,C,D,E
A. Valerian:
Valerian is an herb commonly used for its sedative and anxiolytic properties. There is limited evidence suggesting potential interactions between valerian and warfarin, but it is not considered a major concern for altering warfarin's anticoagulant effects. However, caution is still warranted, and healthcare providers should monitor patients for any signs of increased bleeding if they are using valerian along with warfarin.
B. Ginkgo biloba:
Ginkgo biloba is an herb often used for its cognitive-enhancing properties and to improve circulation. There is some evidence to suggest that ginkgo biloba may interact with warfarin and increase the risk of bleeding due to its anticoagulant effects. Therefore, patients taking warfarin should use ginkgo biloba cautiously and inform their healthcare providers if they are using it.
C. Echinacea:
Echinacea is an herb commonly used to boost the immune system and treat colds and respiratory infections. Some studies suggest that echinacea may interact with warfarin and potentially increase the risk of bleeding. Therefore, it's essential for patients taking warfarin to avoid or use echinacea cautiously and to inform their healthcare providers if they are using it.
D. Ginger:
Ginger is an herb commonly used for its anti-inflammatory and digestive properties. Some studies suggest that ginger may interact with warfarin and increase the risk of bleeding due to its anticoagulant effects. Patients taking warfarin should use ginger cautiously and inform their healthcare providers if they are using it.
E. Garlic:
Garlic is an herb known for its cardiovascular benefits and potential anticoagulant effects. Some studies suggest that garlic may interact with warfarin and increase the risk of bleeding. Patients taking warfarin should use garlic cautiously and inform their healthcare providers if they are using it.

Correct Answer is ["125"]
Explanation
To calculate the rate at which the IV pump should be set to deliver 3,000 mL of intravenous fluids over 24 hours, you would divide the total volume (3,000 mL) by the total time (24 hours):
Rate (mL/hr) = Total volume (mL) / Total time (hours)
Rate = 3,000 mL / 24 hours
Rate ≈ 125 mL/hr
Rounding to the nearest whole number, the IV pump should be set to deliver approximately 125 mL/hr.
Correct Answer is A
Explanation
A. Keep the serum drug level within the therapeutic margin:
This is the correct goal of monitoring peak and trough levels during antibacterial therapy. The therapeutic margin refers to the range of drug concentrations in the bloodstream that achieves optimal therapeutic effects while avoiding toxicity. By monitoring peak and trough levels, healthcare providers can adjust the dosing regimen to maintain drug levels within this therapeutic margin.
B. Increase the therapeutic effect of the drug by gradually decreasing the drug dose:
This statement is incorrect. Monitoring peak and trough levels is not about increasing the therapeutic effect of the drug by gradually decreasing the drug dose. Instead, it's about ensuring that the drug levels are maintained within the appropriate therapeutic range to achieve optimal efficacy without causing adverse effects.
C. Provide maximum physical comfort to the patient:
Monitoring peak and trough levels is not primarily aimed at providing physical comfort to the patient. While optimizing drug therapy can contribute to improved clinical outcomes and patient well-being, the goal of monitoring these levels is specifically related to achieving therapeutic drug concentrations.
D. Treat the main disorder with no psychological distress to the patient:
This statement is unrelated to the goal of monitoring peak and trough levels during antibacterial therapy. While psychological distress may be a consideration in patient care, the primary goal of monitoring drug levels is to ensure therapeutic efficacy and safety.
