The patient requests information on alternative treatments for her arthritis. The nurse provides the patient with information on which of the following supplements?

Dosage (mL) = Desired dose (mg) / Concentration (mg/mL)

Dosage (mL) = 350 mg / (250 mg/5 mL)

Dosage (mL) = 7 mL (rounded to nearest whole number)

Therefore, the nurse should administer 7 mL of amoxicillin suspension.

A. Easy bruising indicates the medication is effective: While some bruising is possible, excessive bruising doesn't necessarily mean the medication is working effectively. It could indicate excessive anticoagulation, requiring dose adjustments.

B. Inject the medication deep into the thigh muscle: Heparin is injected subcutaneously, targeting the fatty tissue layer just beneath the skin. Injecting into the muscle can be painful and decrease absorption.

C. Expect stools to become black and tarry: Black stools can be a sign of upper gastrointestinal bleeding, a potential but uncommon side effect. The nurse should instruct the client to report any black stools but not expect them as a normal occurrence.

D. Use a soft bristle toothbrush: This is important because heparin increases bleeding risk, and a soft-bristled toothbrush minimizes gum irritation and potential bleeding.
