A nurse is caring for a client who has a prescription for levothyroxine.
Which of the following laboratory tests should the nurse monitor?
Serum potassium
Triiodothyronine
Blood urea nitrogen
Prothrombin time
The Correct Answer is B
Explanation B.Triiodothyronine
Levothyroxine is a synthetic form of the thyroid hormone thyroxine (T4). It is converted to triiodothyronine (T3), the active form of the thyroid hormone, in the body. Monitoring the levels of triiodothyronine (T3) can help assess the effectiveness of levothyroxine therapy and ensure that the client's thyroid hormone levels are within the desired therapeutic range.
Serum potassium levels in (option A) should not be monitored because they are not directly affected by levothyroxine. However, imbalances in electrolytes can occur in some individuals with thyroid disorders. Electrolyte levels may be monitored, but it is not the primary focus of monitoring for levothyroxine therapy.
Blood urea nitrogen (BUN) in (option C) should not be monitored because it is a test used to assess kidney function and is not directly related to monitoring levothyroxine therapy.
Prothrombin time (PT) in (option D) should not be monitored because it is a test used to evaluate the clotting function of the blood and is not specifically related to monitoring levothyroxine therapy.

Correct Answer is ["A","B","C","D"]
Explanation
Provide the client with written information about advance directives: It is important for the nurse to educate the client about advance directives, their purpose, and how they can make informed decisions about their healthcare.
Instruct the client that an advance directive is a legal document and must be honored by care providers: The nurse should explain to the client that an advance directive is a legally binding document that guides healthcare decisions, and it must be respected and followed by healthcare providers.
Communicate advance directives status via the medical record and shift report: The nurse should ensure that the client's advance directives status is accurately documented in the medical record and communicated to other members of the healthcare team during shift handoffs. This helps ensure that the client's wishes are known and respected by all involved in their care.
Initiate a power of attorney for health care document: The nurse can assist the client in initiating a power of attorney for healthcare document if the client wishes to appoint someone as their healthcare proxy or agent. This document designates someone to make medical decisions on behalf of the client if they become unable to do so.
The other options listed are not appropriate or accurate in relation to the responsibilities of the nurse regarding advance directives:
Document that the provider discussed-do-not-resuscitate status with the client: While discussing do-not-resuscitate (DNR) status may be part of the advance care planning process, it is not directly related to advance directives as a whole.
Inform the client that an advance directive discontinues further care: This statement is incorrect and misleading. An advance directive does not automatically discontinue care but rather guides the provision of care according to the client's wishes.
Correct Answer is C
Explanation
This response allows the nurse to express genuine interest in the client's perspective and opens up a dialogue to understand the client's concerns or reasons for refusing to learn how to self-administer insulin. It provides an opportunity for the client to express their fears, doubts, or any barriers they may have. By actively listening to the client, the nurse can better address their concerns and provide appropriate education and support tailored to their individual needs.
The other options may come across as confrontational, judgmental, or unhelpful in establishing a therapeutic relationship with the client. It is important for the nurse to approach the situation with empathy, respect, and a non-judgmental attitude to foster effective communication and promote the client's engagement in their own care.
