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

Answer and Explanation

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

Explanation

Placing soiled dressings in a biohazard trash receptacle is the appropriate practice for disposing of potentially infectious materials. It helps prevent the spread of microorganisms and ensures proper handling and disposal of contaminated items.

Clostridium difficile is a spore-forming bacterium that is not effectively killed by alcohol-based hand rubs. Hand hygiene for C. difficile requires the use of soap and water to thoroughly wash the hands.

Droplet precautions typically require the use of a surgical mask, not a gown and gloves. Gown and gloves are used for contact precautions.

The recommended bleach solution for blood spills is typically a 1:10 dilution, not 1:20. This concentration helps ensure effective disinfection and decontamination of the area.

A. A client who is postoperative and reports intermittent nausea B. A client whose blood pressure is 160/90 mm Hg and reports a headache C. A client who is scheduled for surgery in 2 hr D. A client who is postoperative and has a Jackson-Pratt drain

Correct Answer is B

Explanation

Hypertensive crisis is a severe increase in blood pressure that can lead to organ damage or other complications. Prompt assessment and intervention are necessary to prevent further escalation of blood pressure and potential complications.

While all the clients mentioned require attention, the client with elevated blood pressure and a headache poses a higher immediate risk. The nurse should assess the client's blood pressure, evaluate for signs of target organ damage, and initiate appropriate interventions, which may include administering antihypertensive medications as prescribed and monitoring closely for any changes in the client's condition.

The client who is postoperative and reports intermittent nausea can be assessed and managed after addressing the client with the elevated blood pressure and headache.

The client scheduled for surgery in 2 hours can be addressed according to the scheduled timeline.
