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. 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.

Rationale:
A. Limit teaching sessions about the procedure to 20 min: While preschoolers have limited attention spans, the focus should be on using age-appropriate language and explanations rather than strictly timing the teaching session. The quality and clarity of instruction are more important.

B. Ask the parents to wait outside the room during the procedure: Preschoolers often feel safer and more cooperative when a parent is present. Removing parents can increase anxiety and resistance, so parental presence is encouraged.

C. Instruct the child in deep-breathing methods prior to the procedure: Deep-breathing exercises can help with relaxation, but preschoolers may have difficulty understanding or performing them effectively. Simple explanations and reassurance are more appropriate.

D. Explain in simple terms how the procedure will affect the child: Providing a clear, age-appropriate explanation helps the preschooler understand what to expect, reduces fear, and promotes cooperation. Using simple terms tailored to the child’s developmental level is the most effective preparation.
