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.

Explanation
It is not appropriate for the nurse to threaten the client's child with reporting for maltreatment without further assessment and evidence.
Asking the client's child to provide details regarding the client's fractured arm will provide additional information about the client's injury and help the nurse assess the potential for abuse or neglect.
Discussing respite care options with the client's child may help alleviate any caregiver stress or burden, and ensure the client's continued care and safety.
Speaking to the client privately will help establish trust and rapport, and allow the client to disclose any
concerns or issues that they may not feel comfortable sharing in front of their child.
Providing legal advice regarding power of attorney is not within the scope of nursing practice and should be referred to a legal professional. Additionally, the client's capacity to make decisions and appoint a power of attorney should be assessed before providing such advice.
Correct Answer is A
Explanation
Pain in the calf can be a potential symptom of deep vein thrombosis (DVT), which is a serious complication after surgery. Monitoring the client's pulse oximetry can help assess for signs of decreased oxygenation, which may indicate a possible clot or compromised circulation. A decrease in oxygen saturation can be an early indicator of a potential DVT-related complication, such as a pulmonary embolism. Monitoring the pulse oximetry can provide valuable information for timely intervention and management.
Instructing the client to massage the calf gently is not advisable without further assessment and evaluation. Massaging the calf can potentially dislodge a clot if one is present, leading to further complications. It is important to rule out DVT through appropriate diagnostic measures before providing specific instructions for calf massage.
Maintaining the leg in a dependent position while in bed can potentially worsen the symptoms and increase the risk of venous stasis. Elevating the affected leg, rather than maintaining it in a dependent position, can help improve venous return and reduce pain or swelling.
Applying a cold compress to the client's calf is not recommended without further assessment. Heat or cold therapy should be applied based on the underlying cause of the pain. In the case of potential DVT, applying a cold compress can increase vasoconstriction and potentially worsen the condition. It is essential to investigate the cause of the pain first and consult with the healthcare provider before initiating any specific therapies or interventions.
