A client states that she is afraid of receiving vitamin B12 injections because of potential toxic effects, which is the nurse's best response to relieve these fears?
Correct answer
D
Rationale
Vitamin B12 is a water-soluble vitamin, and excess amounts are excreted in urine, making toxicity rare. This response reassures the client by addressing her fear of toxic effects accurately. The other responses are incorrect, as B12 does not typically cause ringing in the ears, rash, or nausea as signs of toxicity.
