Which statement by a client indicates an understanding of self-care precautions when taking warfarin?
"My warfarin dose may need to be readjusted when I take a course of antibiotics."

"I should eat spinach to increase my iron count if my INR goes below two."
"Herbal remedies are fine, but I shouldn't take aspirin without consulting my provider."
The Correct Answer is A
A) Antibiotics can interact with warfarin, potentially affecting the INR, so dose adjustments may be necessary.
B) Pink urine is not an expected side effect of warfarin; this statement is inaccurate.

Correct Answer is ["0.3"]
Explanation
-
Convert the ordered dose from micrograms (mcg) to milligrams (mg):
- 300 mcg = 0.3 mg (since 1 mg = 1000 mcg)
-
Use the formula:
Dose to administer = (Desired Dose ÷ On-Hand Dose) × Quantity Available- Desired Dose (D) = 0.3 mg
- On-Hand Dose (H) = 1 mg
- Quantity Available (Q) = 1 mL
-
Calculate:
0.3 mg ÷ 1 mg × 1 mL = 0.3 mL
The nurse should administer 0.3 mL of the medication.
