A nurse is preparing a client who is to receive chemotherapy for treatment of ovarian cancer. Which of the following actions should the nurse plan to take?

Choice A reason: The Health Care Proxy Does Not Go Into Effect Until I Am Incapable of Making Decisions

This statement is correct. A health care proxy, also known as a durable power of attorney for health care, only becomes active when the individual is no longer capable of making their own medical decisions. Until that point, the individual retains full control over their health care choices1.

Choice B reason: I Have to Choose a Family Member as My Health Proxy

This statement indicates a need for clarification. It is not necessary to choose a family member as a health care proxy. An individual can select any trusted person, whether a family member or a friend, to act as their health care proxy. The most important factor is that the chosen person understands the individual’s wishes and is willing to advocate for them2.

Choice C reason: I Can Change Who I Designate as My Health Care Proxy at Any Time

This statement is correct. An individual can change their designated health care proxy at any time, as long as they are still capable of making their own decisions. It is important to ensure that any changes are documented properly and that all relevant parties are informed of the change3.

Choice D reason: If I Become Incapacitated, End-of-Life Choices Will Be Made by My Proxy

This statement is correct. If an individual becomes incapacitated and is unable to make their own medical decisions, the health care proxy will step in to make decisions on their behalf, including end-of-life choices. The proxy should be well-informed about the individual’s preferences and values to make decisions that align with their wishes4.

Choice A reason: Obtain a 12-lead ECG

Obtaining a 12-lead ECG is a critical action when a client has a potassium level of 6.8 mEq/L, which indicates hyperkalemia. Hyperkalemia can cause serious cardiac dysrhythmias, including life-threatening arrhythmias such as ventricular fibrillation or asystole. An ECG can help detect these abnormalities early, allowing for prompt intervention to prevent cardiac complications. The ECG may show characteristic changes such as peaked T waves, widened QRS complexes, and prolonged PR intervals, which are indicative of hyperkalemia.

Choice B reason: Suggest that the client use a salt substitute

Suggesting that the client use a salt substitute is not appropriate in this situation. Many salt substitutes contain potassium chloride, which can further increase the potassium level in the blood. For a client with hyperkalemia, it is crucial to avoid additional sources of potassium to prevent exacerbating the condition. Therefore, recommending a salt substitute could be harmful.

Choice C reason: Advise the client to add citrus juices and bananas to her diet

Advising the client to add citrus juices and bananas to her diet is also inappropriate. Both citrus juices and bananas are high in potassium and can contribute to an increase in serum potassium levels. For a client with hyperkalemia, it is essential to limit dietary potassium intake to help lower the potassium levels in the blood. Encouraging the consumption of high-potassium foods would be counterproductive and potentially dangerous.

Choice D reason: Obtain a blood sample for a serum sodium level

While obtaining a blood sample for a serum sodium level can be part of a comprehensive assessment, it is not the immediate priority in managing hyperkalemia. The primary concern with a potassium level of 6.8 mEq/L is the risk of cardiac dysrhythmias. Therefore, obtaining an ECG to monitor the heart’s electrical activity is the most urgent and appropriate action. Once the immediate risk is addressed, further laboratory tests, including serum sodium levels, can be conducted as part of the overall assessment and management plan.
