A community health nurse is performing a home visit for a client and is evaluating the home environment for safety. Which of the following findings would indicate to the nurse that the client has a proper understanding of safety in the home?

Rationale:
A. A client who is receiving a blood transfusion and reports low-back pain: Low-back pain during a blood transfusion indicates a possible acute hemolytic reaction caused by ABO incompatibility. This is a life-threatening emergency that requires immediate discontinuation of the transfusion and notifying the provider to prevent renal failure and shock.

B. A female client who is scheduled for chemotherapy and has an RBC count of 4.0 x10⁶/µL (4.2–5.4 x10⁶/µL): Although the RBC count is slightly low, this finding is not immediately life-threatening. The provider should be informed, but the client does not require urgent intervention.

C. A client who is 24 hr postoperative following a transurethral resection of the prostate and has small blood clots in the drainage tubing: Small clots are expected during the first 24 to 36 hours post-TURP due to residual bleeding from the surgical site.

D. A client who is 2 days postoperative following placement of an ascending colostomy and has shreds of bloody mucus in the bag: Small amounts of bloody mucus are normal during the early postoperative phase as the bowel mucosa heals.

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.
