A nurse is providing dietary teaching to a client who has chronic kidney disease (CKD). The nurse should instruct the client to limit which of the following nutrients? (Select all that apply.)

The patient is apneic (not breathing) and has no palpable pulses, indicating a cardiac arrest or severe cardiovascular compromise. In this situation, the most appropriate action for the nurse to take next is to start cardiopulmonary resuscitation (CPR) immediately.

CPR is a life-saving procedure that combines chest compressions and rescue breaths to circulate oxygenated blood to vital organs when the heart is not effectively pumping. In the case of cardiac arrest, early initiation of CPR is critical to improve the chances of survival and minimize potential brain damage.

The heart monitor shows sinus tachycardia, rate 132, which suggests that the electrical impulses are reaching the heart, but the heart is not effectively pumping blood due to the lack of a palpable pulse. This condition requires immediate intervention with CPR rather than other treatments such as synchronized cardioversion (option A) or administering atropine (option D).

While applying supplemental oxygen via a non-rebreather mask (option C) is generally important in many emergency situations, it is not the immediate priority when a patient is apneic and has no palpable pulses. In such cases, CPR takes precedence to restore circulation and maintain oxygen delivery to the body's vital organs.

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.
