The nurse is caring for a client immediately following the insertion of a permanent pacemaker. Which intervention should be included in the plan of care?

A. The P-P and R-R distances are equal and regular: Equal and regular spacing between P-P and R-R intervals indicates that both atrial and ventricular rhythms are regular. This is a fundamental aspect of rhythm interpretation, helping to distinguish between regular and irregular rhythms such as atrial fibrillation or sinus arrhythmia.

B. The rhythm rate using a 3-second strip: Assessing the heart rate using a 3-second or 6-second ECG strip helps determine whether the rhythm is bradycardic, tachycardic, or within normal limits, which is crucial for accurate rhythm classification.

C. The duration of the U waves: U waves are typically small and follow the T wave. Although their presence can suggest conditions like hypokalemia, they are not routinely assessed in basic rhythm identification. Evaluating U wave duration is more relevant in electrolyte imbalance analysis than in identifying rhythm type.

D. There is a QRS complex after each P wave: A consistent QRS following every P wave indicates effective conduction from the atria to the ventricles. Each atrial depolarization (P wave) should be followed by a ventricular depolarization (QRS complex) if the signal is being conducted properly through the AV node. This finding supports a diagnosis of sinus rhythm and helps rule out AV blocks, where conduction may be delayed or blocked entirely.

E. P waves are present, upright and rounded: P waves that are upright and rounded in lead II suggest the electrical impulse is originating from the SA node. Their presence and morphology are essential criteria for identifying sinus rhythm and differentiating it from atrial arrhythmias like flutter or fibrillation.

A. Assist the client from the stretcher to a wheelchair: Immediately after electroconvulsive therapy (ECT), the client is still recovering from anesthesia and may experience confusion, drowsiness, or muscle weakness. Transferring the client prematurely poses a fall risk and is not appropriate as the first action.

B. Orient the client and offer reassurance: While reorientation and reassurance are important aspects of post-ECT care, safety and physiological stability must be assessed first. This action should follow an initial assessment of vital signs and level of consciousness.

C. Encourage the client to drink some fluids: Offering fluids too soon after ECT is inappropriate because the client may have impaired swallowing reflexes from anesthesia or sedation. Ensuring the airway is clear and the client is fully alert must precede oral intake.

D. Assess vital signs and orient client to the PACU environment: The priority after any procedure involving anesthesia is to assess vital signs to ensure hemodynamic stability and monitor for complications. Once stable, the nurse can begin to orient the client, which is often needed after ECT due to temporary disorientation or memory lapses.
