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
A.Wearing a face mask does not increase the risk of injury. In fact, it helps protect the client from infections, especially if they have concurrent neutropenia, which is common in conditions affecting the bone marrow.
B.Green, leafy vegetables are rich in vitamin K, which plays a role in clotting. However, they do not directly increase the risk of injury in a client with thrombocytopenia. While vitamin K affects clotting factors, thrombocytopenia primarily involves a deficiency of platelets, which are necessary for clot formation.
C.Clients with thrombocytopenia have a low platelet count, which increases their risk of bleeding. Using a firm-bristled toothbrush can cause gum trauma and bleeding, leading to complications such as prolonged bleeding or infection. A soft-bristled toothbrush or an alternative oral hygiene method (such as an oral swab) is recommended to minimize injury.
D.Adequate sleep does not increase the risk of injury. In fact, it may support overall health and immune function.
Correct Answer is C
Explanation
Delirium is a state of acute confusion and cognitive impairment that can cause disorientation and difficulty with time perception. Reminding the client of the day and time frequently helps provide orientation and reduce confusion. It can help ground the client in reality and improve their understanding of their current circumstances.
Avoiding discussing the client's fears can hinder their ability to express and address their concerns. It is important to provide a safe and supportive environment where the client can communicate their fears and feelings.
Offering the client several choices at mealtimes might be overwhelming and confusing for someone experiencing delirium. It is generally better to provide structure and simplicity in their meal options, reducing decision-making demands.
Alternating daily caregivers can disrupt continuity of care and increase the client's confusion. Consistency in the caregiving team can help establish a therapeutic relationship and familiarity, which can aid in managing delirium.
