Which statement, made by the client diagnosed with unstable angina, reflects an understanding of the nurse's discharge teaching?

Choice A Reason:
Switching to heparin is not the standard response for a high INR. Heparin may be used in conjunction with warfarin when starting anticoagulation therapy, but it is not typically used as a substitute in response to an elevated INR.

Choice B Reason:
Giving the dose as prescribed would not be appropriate when the INR is significantly above the therapeutic range. Continuing the same dose could increase the risk of bleeding complications.

Choice C Reason:
Increasing the dose would be contraindicated as the INR is already too high. Increasing the warfarin dose would further elevate the INR and increase the risk of bleeding.

Choice D Reason:
Holding the dose is the correct action when the INR is significantly above the therapeutic range, which is generally between 2.0 to 3.0 for most indications. The healthcare provider should be notified, and the warfarin dose should be held until the INR returns to the therapeutic range. Vitamin K may also be administered to help lower the INR more quickly if necessary.

Choice A Reason
Providing a quiet atmosphere for undisturbed sleep is beneficial for all patients, especially those recovering from illness. However, it does not directly address the issue of activity intolerance. Adequate rest is important, but the primary concern with activity intolerance is managing energy levels during waking hours to improve the patient's ability to engage in activities.

Choice B Reason
Clustering activities in the morning may seem like a good strategy when the patient is well-rested. However, this could lead to rapid depletion of energy reserves and exacerbate activity intolerance. It is more effective to spread activities throughout the day to manage energy levels better.

Choice C Reason
Identifying ways to conserve energy is a key intervention for managing activity intolerance. This can include teaching the patient energy-conservation techniques, such as sitting while showering or dressing, taking frequent breaks, and prioritizing tasks. This approach helps patients with folic acid deficiency anemia to participate in activities without excessive fatigue.

Choice D Reason
While nutrition is important in the management of anemia, recommending small frequent iron-rich meals does not directly address activity intolerance. Folic acid deficiency anemia requires dietary intake of folate-rich foods or supplements. Iron is important, but the focus for folic acid deficiency should be on folate.
