client with acute coronary syndrome has returned to the coronary care unit after having angioplasty with stent placement. Which assessment data indicate the need for immediate action by the nurse?

For a patient admitted with syncopal (fainting) episodes of unknown origin, the most appropriate action to include in the plan of care is to instruct the patient to call for assistance before getting out of bed.

Syncope can be caused by various factors, including orthostatic hypotension (a drop in blood pressure upon standing) or cardiac-related issues. One of the common triggers for syncopal episodes is getting up from a lying or sitting position too quickly. By instructing the patient to call for assistance before getting out of bed, the nurse aims to prevent falls and potential injuries that may occur due to sudden fainting episodes.

While it's essential to educate the patient about potential causes of syncope (option A) and the benefits of implantable cardioverter-defibrillators (option B) if applicable to their condition, these actions may not directly address the immediate safety concern of preventing falls during syncopal episodes.

Option D, teaching the patient about the need to avoid caffeine and other stimulants, may be relevant if stimulants are identified as potential triggers for syncope in this particular patient. However, it is not the most critical action to include in the initial plan of care for a patient with syncopal episodes of unknown origin.

In summary, the top priority for the nurse is to ensure the safety of the patient by instructing them to call for assistance before getting out of bed to prevent falls during syncopal episodes until further evaluation and diagnosis can determine the cause of the fainting episodes.

During the 48 hours after a myocardial infarction (MI), the highest priority for monitoring the patient is for dysrhythmias. After an MI, the heart's electrical system can be disrupted, leading to various types of abnormal heart rhythms (dysrhythmias). Dysrhythmias can be life-threatening and require prompt recognition and intervention.

Other options:

B) Anxiety and fear: Anxiety and fear are common emotional responses after an MI, but they are not the highest priority for monitoring during the immediate post-MI period. Emotional support and counseling are essential, but they do not require continuous monitoring.

C) Metabolic acidosis: Metabolic acidosis is not a common complication of an acute MI. It may occur in certain situations, such as when there is inadequate perfusion to tissues, but it is not the highest priority during the immediate post-MI period.

D) Medication side effects: Monitoring for medication side effects is important but is not the highest priority during the immediate post-MI period. Many patients will receive medications to manage pain, reduce clot formation, and stabilize their heart function. The nurse should monitor for side effects but not as a higher priority compared to dysrhythmias.
