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 ["B"]
Explanation
a. Asking other group members to limit their speaking may place unnecessary pressure on the quiet client and make them feel singled out. The goal is to create a supportive environment where the client feels comfortable contributing when they are ready. Limiting the other group members' participation does not address the individual needs of the client who is silent.
b.Some clients may need extra time to process information or formulate their responses, particularly in a group setting where they might feel overwhelmed or anxious. Allowing the client extra time respects their pace and encourages participation without pressuring them.
c.Appointing the client to lead the discussion if they cannot contribute are not appropriate actions. These approaches can increase the client's discomfort and create a negative atmosphere, which goes against the principles of group therapy. It is important to foster an inclusive and supportive environment that encourages participation at each person's pace.
d.Telling a client to leave the group if they cannot contribute is not appropriate action. These approaches can increase the client's discomfort and create a negative atmosphere, which goes against the principles of group therapy.
Correct Answer is D
Explanation
Furosemide works by promoting diuresis, which helps to reduce fluid volume overload in heart failure. Increased urinary output indicates that the medication is effectively removing excess fluid from the body. This can help alleviate symptoms such as edema and fluid retention commonly associated with heart failure. Therefore, an increased urinary output is a positive response to furosemide therapy in this context.
Decreased BUN (blood urea nitrogen) levels and weight loss are also expected outcomes of diuretic therapy, further indicating the effectiveness of the medication. However, a decreased hemoglobin level is not directly related to the efficacy of furosemide and might be indicative of other factors such as anemia or bleeding, requiring further assessment and intervention.
