A patient on warfarin is found to have an INR of 5.0. What is the most appropriate action by the nurse?

Administer vitamin K per provider's orders.

Increase the dose of warfarin and monitor INR more frequently per provider's orders.

Discontinue warfarin and administer a dose of heparin per provider's orders.

Continue warfarin and monitor for any symptoms of bleeding per provider's orders.

Answer and Explanation

The Correct Answer is A

A. An INR of 5.0 indicates a significantly increased risk of bleeding, and administering vitamin K is the appropriate antidote for reversing the effects of warfarin. This is a critical intervention to restore coagulation.

B. Increasing the dose of warfarin is inappropriate in this scenario because the INR is already elevated; it would further increase bleeding risk.

C. While heparin can be used for anticoagulation, it is not appropriate to administer it while the INR is dangerously high without reversing the warfarin first.

D. Continuing warfarin is unsafe at this INR level due to the high risk of bleeding; monitoring for symptoms without intervention is not adequate care.

Correct Answer is B

Explanation

A. Rebound hypertension can occur if antihypertensive medications are abruptly stopped, but it is not a direct reason for switching from an ACE inhibitor to an angiotensin II receptor blocker.

B. A persistent cough is a well-known side effect of ACE inhibitors due to the accumulation of bradykinin. If the client experienced this side effect, it would likely prompt the healthcare provider to switch to an angiotensin II receptor blocker, which does not typically cause this issue.

C. A transient ischemic attack (TIA) would require urgent intervention but is not a reason for changing from an ACE inhibitor to an angiotensin II receptor blocker.

D. Non-adherence to ACE inhibitor treatment may lead to ineffective blood pressure control but would not directly justify a switch to a different class of medication.

Correct Answer is ["0.6"]

Explanation

Volume (mL) = Desired dose (units) / Concentration (units/mL)

In this case:

Desired dose = 6000 units
Concentration = 10000 units/mL

Plugging the values into the formula:

Volume = 6000 units / 10000 units/mL = 0.6 mL
