A nurse is providing medication teaching about disulfiram for a client who has alcohol use disorder. Which of the following statements by the client indicates an understanding of the teaching?

Rationale:
A. After inflation, deflate a blood pressure cuff on the client's arm while palpating their brachial pulse: This technique assesses blood pressure, not pulse deficit. Pulse deficit requires comparing simultaneous heartbeats at different sites rather than using a cuff for measurement.

B. Compare the client's carotid pulse while resting to their carotid pulse after standing for 1 min: This evaluates orthostatic changes in heart rate, not pulse deficit. Pulse deficit specifically identifies a difference between apical and peripheral pulses during the same cardiac cycle.

C. Measure the client's apical pulse while another nurse measures their radial pulse: A pulse deficit is determined by counting the apical pulse and comparing it to the radial pulse simultaneously. A difference indicates that some heartbeats are not producing a palpable peripheral pulse, which is important in conditions like atrial fibrillation.

D. Assess both of the client's radial pulses at the same time and compare the quality of pulsations: Comparing radial pulses on both sides evaluates for peripheral pulse equality or arterial obstruction, not pulse deficit.

Rationale:
A. Hemothorax: Hemothorax is accumulation of blood in the pleural space, typically caused by trauma, surgery, or ruptured vessels. Atrial fibrillation does not directly increase the risk of hemothorax.

B. Cardiac tamponade: Cardiac tamponade occurs when fluid accumulates in the pericardial sac, impairing cardiac output. This condition is usually associated with trauma, pericarditis, or post-surgical complications, not atrial fibrillation.

C. Pulmonary emboli: Atrial fibrillation can lead to stasis of blood in the atria, especially the left atrial appendage, increasing the risk of thrombus formation. If a clot dislodges and travels to the lungs, it can cause a pulmonary embolism, making this a serious complication to monitor for.

D. Widened pulse pressure: Widened pulse pressure reflects the difference between systolic and diastolic blood pressure and is associated with conditions like aortic regurgitation. It is not a direct consequence of atrial fibrillation and is not considered a primary risk in these clients.
