The nurse is caring for a client diagnosed with acute decompensated heart failure. The client is increasingly anxious and restless. The nurse should plan to implement which prescribed orders to assist in relieving these symptoms?

A. Sinus Bradycardia, with First Degree AV block, Rate 40: The rhythm strip shows regular P waves, each followed by a QRS complex, indicating a sinus rhythm. The PR interval is prolonged (greater than 0.20 seconds) but remains consistent across all beats. This confirms a first-degree AV block. The ventricular rate is approximately 40 bpm, consistent with sinus bradycardia.

B. Second Degree AV block – Mobitz I, Rate 40: Mobitz I (Wenckebach) is characterized by a progressively lengthening PR interval followed by a dropped QRS complex. This pattern is not seen here; the PR intervals are consistently prolonged.

C. Second Degree AV block – Mobitz II, Rate 40: Mobitz II involves intermittent dropped QRS complexes without progressive PR prolongation. In the strip, no QRS complexes are missing, ruling out Mobitz II.

D. Third Degree Heart Block, Rate 40: In complete heart block, there is no relationship between P waves and QRS complexes (AV dissociation). Here, the P waves are consistently followed by QRS complexes, indicating intact conduction, even if delayed. This therefore is not a third-degree block.

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.
