A. While assessing potassium levels is important for clients on diuretics, the immediate concern is the client's dizziness, which indicates a potential issue with blood pressure.

B. Teaching the client about the potential for orthostatic hypotension caused by hydrochlorothiazide and instructing them on safety measures (e.g., standing up slowly) is crucial to prevent falls and address the dizziness.

C. Bed rest is not necessary; the client should be educated about managing dizziness instead.

D. Withholding the medication is not warranted unless directed by a healthcare provider; the focus should be on safety education.

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.
