A nurse is assessing a client who has a new diagnosis of heart failure. Which of the following findings should the nurse expect?

Choice A reason: Concern about skin staining indicates the Z-track method, which prevents medication leakage into subcutaneous tissue, reducing irritation or discoloration. This technique is used for medications like iron dextran, where staining is a risk, making this the correct patient statement.

Choice B reason: Wanting to reduce injection pain does not specifically indicate Z-track, which is used to prevent leakage, not primarily pain. Other techniques (e.g., slow injection) address pain, making this statement unrelated to Z-track use.

Choice C reason: An allergy to the medication contraindicates administration, not indicates a specific technique like Z-track. The method addresses leakage, not hypersensitivity, making this statement irrelevant to the Z-track method’s purpose.

Choice D reason: Wanting fast-acting medication does not relate to Z-track, which ensures deep delivery but does not affect onset speed. Intramuscular routes generally have fixed absorption rates, making this statement unrelated to the Z-track indication.

Choice A reason: Oranges have minimal vitamin K, which does not significantly affect warfarin’s anticoagulant effect. They are safe for consumption, making this an incorrect food to avoid.

Choice B reason: Spinach is high in vitamin K, which counteracts warfarin by promoting clotting factor synthesis. Clients should limit such foods to maintain stable anticoagulation, making this the correct choice.

Choice C reason: Chicken breast is low in vitamin K and does not interfere with warfarin. It is a safe protein source, making it incorrect to include in foods to avoid.

Choice D reason: White bread contains negligible vitamin K, having no significant impact on warfarin efficacy. It is safe for consumption, making it incorrect for the teaching.
