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 C
Explanation
Dependent personality disorder is characterized by an excessive reliance on others for decision-making and a fear of being alone or taking responsibility. Encouraging the client to be assertive helps promote their independence and self-confidence. It allows them to express their needs and preferences, make decisions, and take responsibility for their own actions. Empowering the client to be assertive can enhance their overall well-being and promote healthier relationships.
Limiting the client's social interactions may exacerbate their dependency and hinder their progress in developing more self-reliance and independent coping skills. It is important to encourage appropriate and healthy social interactions while also promoting the client's independence.
Maintaining a verbal no-harm contract with the client is a strategy more commonly used for clients at risk of self-harm or harm to others. It may not be directly applicable to the care of a client with dependent personality disorder unless there are specific safety concerns. Assuming responsibility for making the client's decisions would reinforce their dependency and enable their avoidance of taking personal responsibility. It is important to promote autonomy and support the client in making their own decisions whenever possible.

Correct Answer is D
Explanation
The nurse should intervene when the AP raises all four side-rails on the client's bed. While it is important to ensure the client's safety and minimize the risk of falls, raising all four side-rails can be considered a restraint and may not be the best practice for fall prevention. The use of physical restraints, including all four side-rails, can lead to adverse outcomes such as entrapment, increased agitation, and decreased mobility.
Locking the wheels on the client's bed: This is an appropriate action to prevent the bed from rolling and ensures stability.
Clearing furniture from the path leading to the bathroom: This is a good practice as it creates a clear and safe path for the client to walk without obstacles.
Assisting the client to the bathroom every 2 hours: This is a proactive measure to prevent falls by ensuring regular toileting and minimizing the need for the client to get up and move independently.
It's important to promote mobility and independence for the client while ensuring their safety.
