A nurse is admitting a client who has a history of atrial fibrillation. Which of the following conditions should the nurse recognize atrial fibrillation places the client at risk for?
Hemothorax
Cardiac tamponade
Pulmonary emboli
Widened pulse pressure
The Correct Answer is C
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.

Correct Answer is ["A","B"]
Explanation
Rationale for Correct Choices
• Meconium aspiration syndrome: The presence of thick green amniotic fluid indicates meconium-stained fluid, which the post-term infant may aspirate during delivery. Meconium aspiration can obstruct the airways, cause chemical pneumonitis, and lead to respiratory distress requiring immediate intervention and supportive care.
• Macrosomia: Post-term infants are at increased risk of macrosomia due to prolonged gestation and continued growth in utero. Macrosomic infants face complications such as difficult labor, shoulder dystocia, and birth injuries, necessitating careful monitoring and potential interventions during delivery.
Rationale for Incorrect Choices
• Intraventricular hemorrhage: This condition is primarily associated with preterm infants due to fragile germinal matrix vasculature. The post-term infant in this scenario is less likely to develop intraventricular hemorrhage.
• Bronchopulmonary dysplasia: Chronic lung disease usually develops in preterm infants who have required prolonged mechanical ventilation or oxygen therapy. The term post-term infant is not at high risk for this condition immediately after birth.
Correct Answer is B
Explanation
Calculation:
- Identify the client's weight in kilograms (kg) and height in meters (m).
Weight = 75 kg
Height = 1.8 m
- Calculate the square of the height in meters (m squared).
Height squared = 1.8 m x 1.8 m
= 3.24 m squared.
- Calculate the BMI.
BMI = Weight (kg) / Height (m squared)
= 75 kg / 3.24 m squared
= 23.148
- Round the answer to the nearest tenth.
= 23.1
