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 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.
Correct Answer is A
Explanation
An incident report is a tool used to document any unexpected or adverse event that occurs in the healthcare setting. It is important to report incidents to ensure proper investigation, analysis, and implementation of measures to prevent future occurrences.
In this example, the incident involves an error with an electronic IV pump resulting in the delivery of an incorrect amount of fluid, which can have serious implications for the client's safety and well-being.
The other examples listed may require further actions but may not necessarily require an incident report:
- A nurse discovers that a client's family member has administered a PCA dose: While it is concerning that a client's family member administered a patient-controlled analgesia (PCA) dose, it is more appropriate to address this situation through immediate intervention, education, and communication with the healthcare provider. An incident report may not be necessary unless there are further complications or system issues related to this incident.
- A nurse observes another nurse remove wrist restraints one at a time from a client who is currently calm: While the observation of improper restraint removal raises concerns about proper restraint protocol, it is more appropriate to address this situation through immediate intervention and communication with the involved nurse and healthcare provider. Depending on the severity of the situation, an incident report may or may not be warranted, but it is not the primary action in this case.
- A nurse observes a client vomiting after receiving an oral pain medication: While it is important to assess and address the client's condition and any adverse reactions, such as vomiting after receiving medication, it may not necessarily require an incident report. The nurse should assess the client, notify the healthcare provider, and document the incident appropriately in the client's medical record.
