A nurse is caring for a client who has a prescription for warfarin. Which of the following laboratory tests should the nurse monitor?
Triiodothyronine
Blood urea nitrogen
Arterial blood gases
Prothrombin time
The Correct Answer is D
Warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. Therefore, it is important to monitor the client's clotting ability to ensure that the medication is working properly and not causing any adverse effects. The laboratory test that is used to monitor warfarin therapy is the prothrombin time (PT), which measures the time it takes for the blood to clot. The nurse should monitor the client's PT regularly and adjust the dosage of warfarin as necessary to maintain the therapeutic range. Option a (Triiodothyronine) is a thyroid hormone and is not directly related to warfarin therapy. Option b (Blood urea nitrogen) is a measure of kidney function and is also not directly related to warfarin therapy. Option c (Arterial blood gases) is a measure of oxygen and carbon dioxide levels in the blood and is not related to warfarin therapy.

Correct Answer is {"dropdown-group-1":"C","dropdown-group-2":"B"}
Explanation
The client's symptoms are concerning for angina or a possible myocardial infarction (heart atack) and require immediate intervention. Nitroglycerin is a medication that can help relieve chest pain associated with cardiac events by dilating blood vessels and reducing the workload on the heart.
Therefore, the nurse should administer nitroglycerin as ordered by the provider. After administering nitroglycerin, the nurse should obtain an ECG to assess for any changes in cardiac rhythm or evidence of ischemia (lack of blood flow to the heart muscle).
The ECG can provide important diagnostic information and guide further treatment decisions.
Correct Answer is C
Explanation
A nurse assisting with the care of a client who is 6 hours postoperative following a right total knee arthroplasty should check the client's pedal pulses every hour. This is important to assess the adequacy of blood flow and tissue perfusion to the extremity.
It is also important to monitor the client's pain level, administer pain medication as ordered, and encourage the client to perform exercises as appropriate.
The head of the client's bed should be maintained in a semi-Fowler's position to promote optimal respiratory function, and the client's dressing should be changed only as needed and with sterile technique.
An abductor wedge is not typically used following knee arthroplasty surgery.
