Question 1 of 5
When administering dobutamine to a client, what is the most important parameter to assess?
Correct Answer: A
Rationale: The correct answer is A: Blood pressure. When administering dobutamine, a medication that increases heart contractility, the most important parameter to assess is blood pressure. This is because dobutamine can cause significant changes in blood pressure, including hypotension or hypertension, which can have serious implications for the client's hemodynamic stability. Monitoring blood pressure allows for timely intervention and adjustment of the medication dosage to ensure optimal cardiovascular function. Heart rate (B), oxygen saturation (C), and respiratory rate (D) are also important parameters to monitor but are not the primary concern when administering dobutamine, as its effects on blood pressure are more critical for patient safety and treatment efficacy.
Question 2 of 5
The client on warfarin has an INR of 4.5. What is the most appropriate action by the nurse?
Correct Answer: A
Rationale: The correct answer is A: Administer vitamin K. When a client on warfarin has an INR of 4.5, it indicates over-anticoagulation, putting them at risk of bleeding. Vitamin K helps reverse the effects of warfarin by promoting clotting factors. Administering vitamin K will lower the INR back into the therapeutic range. Holding the next dose of warfarin (B) is not enough to rapidly reverse the effects. Increasing the dose of warfarin (C) would worsen the over-anticoagulation. Monitoring the INR closely (D) is important but not the immediate action needed for a high INR.
