A client with a deep vein thrombosis has been receiving warfarin sodium 2.5 mg PO daily. The client's International Normalized Ratio (INR) is 5.0. The nurse is aware that the medication dose needs to be:

increased.

given as prescribed.

cut in half.

held.

Answer and Explanation

The Correct Answer is D

A.   An INR of 5.0 indicates that the blood is significantly thinner than the therapeutic range (typically 2.0 to 3.0 for DVT treatment). Increasing the dose of warfarin would further increase the risk of bleeding.
B.   Continuing with the prescribed dose of 2.5 mg is not appropriate at this time. The INR is above the safe therapeutic range, indicating a need for adjustment, not maintenance of the current dose.
C.   While reducing the dose may be necessary, cutting it in half may not adequately address the high INR. The more appropriate action would involve holding the dose or significantly adjusting it based on the INR and clinical guidelines.
D.   An INR of 5.0 is a critical value that suggests the client is at an increased risk of bleeding. The appropriate action in this case is to hold the warfarin dose and notify the healthcare provider for further evaluation and management. Depending on clinical protocols, the provider may recommend administering vitamin K to reverse the effects of warfarin, especially if there are signs of bleeding or if the INR is critically high.

Correct Answer is ["37.5"]

Explanation

Drip rate (drops per minute) = (Volume to be infused (mL) x Drop factor) / Time (minutes)

3 hours = 3 * 60 = 180 minutes
Drip rate = (450 mL x 15 drops/mL) / 180 minutes Drip rate = 6750 / 180
Drip rate = 37.5 drops per minute
Therefore, the nurse should regulate the IV at a rate of 37.5 drops per minute.

A. Instruct the client how to perform biofeedback exercises B. Place the client's residual limb in the dependent position C. Explain to the client his left leg has been amputated D. Medicate the client with narcotic analgesic immediately

Correct Answer is D

Explanation

A. While biofeedback can be a helpful technique for managing pain in the long term, it is not an immediate intervention for acute pain. The client is expressing urgent pain that requires prompt action, so this option does not address the immediate need.
B. Placing the residual limb in a dependent position (below the level of the heart) can increase swelling and may worsen the pain. After surgery, the limb should typically be elevated to minimize swelling, especially in the early postoperative period.

C. While it is important for clients to understand their situation, explaining the amputation does not provide immediate relief for acute pain. The client is likely already aware of the amputation and is in distress, so this option is not a priority at this moment.
D. This is the most appropriate intervention. The client is experiencing significant pain, and administering a narcotic analgesic can provide immediate relief. Pain management is a priority in the postoperative setting, especially in the first few hours after surgery.
